▼ Le laboratoire INSERM U908 a montré que le Nerve Growth Factor (NGF) et son précurseur, le proNGF, sont impliqués dans l’agressivité des tumeurs mammaires via des effets sur la croissance, l’angiogenèse ou encore la migration/invasion. Pour autant, aucunes thérapies ciblées n’a à ce jour été approuvée suite à des essais cliniques de traitements visant à inhiber les effets du (pro)NGF et de leurs récepteurs dans les cancers. Ces résultats indiquent que la phosphorylation de TrkA est nécessaire mais pas suffisante pour expliquer le(s) mécanisme(s) par lequel(s) le NGF ou son précurseur participe(nt) au développement tumoral. L’obtention de lignées tumorales résistantes au lestaurtinib est un phénomène rapide, nous avons donc émis l’hypothèse que la signalisation de TrkA indépendante de sa phosphorylation existe de façon « innée » dans les cellules tumorales. Par l’analyse protéomique, nous avons ainsi découvert que le NGF induit le recrutement de CD44 et d’une cascade de signalisation p115RhoGEF/RhoA/ROCK1 (Aubert L*, Guilbert M* et al, Oncotarget, 2015 ; *co-premier auteur). Nous avons ainsi montré que le NGF via le complexe TrkA/CD44 induit la migration et l’invasion des cellules cancéreuses de sein in vivo, et augmente la tumorigénicité in vivo. Quant au proNGF, j’ai pu observer qu’il induit l’internalisation de l’EGFR par la phosphorylation du résidu Y1068. Il en résulte une diminution des effets prolifératif et pro-invasif de l’EGF dans les cellules tumorales. Ces résultats fondamentaux sont tout à fait intéressants même s’ils nécessitent leurs consolidations et doivent permettre de démontrer le caractère pronostic de la détection de TrkA et ses corécepteurs dans le cancer. Ainsi nos études permettront le développement de thérapie ciblée par des firmes pharmaceutiques.
The INSERM U908 unit has showed that Nerve Growth factor (NGF) and its precursor (ProNGF) are implicated in tumor agressivness via their effects on growth, angiogenesis or migration/invasion and metastasis. Nevertheless, (pro)NGF and their receptors targeted therapies failed to demonstrate efficiency and clinical trial are disappointing. These results indicate that TrkA phosphorylation is not sufficient to explain molecular mechanisms of (pro)NGF effects on tumors. Indeed, we obtained lestaurtinib resistant cell lines within 3 weeks of treatment which indicated that resistant mechanisms are innate. So, by functional proteomics analyses, we described that NGF induced the formation of TrkA/CD44 complex and then the recruitment of p115RhoGEF/RhoA/ROCK1 signalling cascade (Aubert L*, Guilbert M* et al, Oncotarget, 2015 ; *equally contributed to this work). We showed that CD44 mediated effects participate to invasive effects of NGF in vitro, and in vivo, we demontrated that CD44 increases NGF induced tumoriginicity. In a second part, I observed that the proNGF regulated EGFR turn over through its phosphorylation on Y1068. This effect on EGFR decreased proliferative and pro-invasive effects of EGF in cancer cells. These fundamental results are…

▼ Epithelial ovarian cancer is a leading cause of death from gynecological malignancies. Challenges in effectively treating patients with metastatic disease and preventing chemo-resistance can be attributed to the insufficient understanding of the biology and the mechanisms involved in ovarian cancer metastasis. Epithelial ovarian carcinoma (EOC) metastasis is characterized by the shedding of malignant cells from the surface of the primary tumor and their implantation onto the peritoneal surface lining the abdominal cavity in addition to more distant sites. This shedding of malignant cells from the primary site results as either single cells or free-floating multicellular aggregates, known as spheroids, in the ascites. Although single cells and spheroids may potentially seed metastases, considerable evidence now suggests that the aggregation of cells is important for anchorage-independent cell survival and growth, and spheroid formation may represent an important intermediate survival mechanism to facilitate EOC dissemination. This project, thus, aimed to characterize CD44s in EOC spheroids and its functional significance in epithelial ovarian carcinoma metastasis.
Recent studies have uncovered human transmembrane cell adhesion molecule
CD44 standard (CD44s) isoform expression correlating with high grade and advance-stage ovarian carcinoma. Moreover, it has also been suggested that CD44s may be an important mediator of ovarian cancer cell implantation in the peritoneal cavity enhancing the metastatic potential of ovarian cancer cells. Therefore, we investigated the functional significance of
CD44 standard by means of in vitro culture experiments with ovarian cancer spheroids.
After characterizing 8 EOC cell lines, a spectrum of
CD44 expression was observed and we chose two cell lines with high CD44s (ES-2 and SKOV-3) and two cell lines low in CD44s (OVCAR-4 and OVSAHO) for further testing. Interestingly, the high CD44s-expressing cell lines formed larger spheroids that adhered significantly faster to a monolayer of primary mesothelial cells. Silencing of
CD44 using CRISPR/Cas9 in these 2 cell lines reduced spheroid formation suggesting that differential expression of CD44s plays a role in cell-cell adhesion. When we i.p. injected ES-2
CD44-/- cells into athymic nude mice, decreased ascites production and mesentery tumor burden were observed as well as increased overall survival. However,
CD44 knockout also significantly increased metastasis to the lung suggesting a suppressive role for
CD44 in EOC distant metastasis, as well. This data implies that
CD44 enhances the metastatic potential in ovarian cancer spheroids and regulates organ-specific dissemination of ovarian cancer cells, favoring peritoneal dissemination. However, high
CD44 expression prevents metastatic dissemination to distant sites, including lungs, thereby limiting its use as a therapeutic target for disease management.

▼ Mouse models of malignant glioma that accurately recapitulate the genetic and phenotypic heterogeneity are essential for advancing brain tumor therapeutics. We have developed a novel model using the Sleeping Beauty transposable element to achieve chromosomal integration of human oncogenes into endogenous brain cells of any mouse strain. The phenotype of these genetically engineered brain tumors is influenced by the combination of oncogenes delivered, but many of the pathological features of malignant human glioma are present in the majority of cases. At least five different genes can be cotransfected simultaneously, including reporters that allow measurement of tumor progression. The flexibility of this model enabled studies on the role of the microenvironment in brain tumor development. The data presented here demonstrate that glioma cells make an abundance of CD44 and HA starting early in tumor development and continue to make both receptor and ligand as gliomas progress to highly invasive disease. We show that CD44-/- tumors progressed significantly slower than CD44+/+ tumors, but that expression of full length CD44 within tumors restores the CD44-/- tumor progression. In addition, we show that CD44 loss of function caused severe impairment in single cell motility. The data presented here suggest that HA-engaged CD44 mediates tumor progression by facilitating glioma cell invasion. These studies highlight the therapeutic potential for targeting the infiltrative glioma population through antagonists of the HA-CD44 complex.

▼ Glioblastoma (GBM) is a highly aggressive brain cancer (generally, “glioma”) with poor patient prognosis, even with current standard treatments. In order to rationally develop novel treatments that can significantly extend patient survival, we must first understand at a basic scientific level how the disease progresses. GBM is thought to be fatal due to highly invasive cells that migrate beyond the visible bulk tumor and lead to tumor recurrence after therapeutic intervention. Therefore, we sought to investigate what makes GBM cells invasive at the single-cell level (Chapter 1). Using a genetically induced mouse glioma model and confocal imaging of intact tumor-containing brain slices, we found that, consistent with previous biophysical models, glioma cell migration is biphasic with respect to the concentration of the transmembrane cell adhesion molecule CD44. By contrast, cell proliferation is independent of CD44 level. Additionally, mouse model and human patient survival are also biphasic with respect to CD44 level, with poorest prognosis occurring at intermediate CD44 levels. Thus, migration and survival are both biphasic and are anti-correlated to each other, suggesting that CD44-dependent migration directly affects survival outcomes. We next investigated how these single-cell behaviors impact overall tumor growth and progression (Chapter 2). Noticing that previous models of GBM migration use parameter values for migration rate (defined by a diffusion coefficient, also known as a random motility coefficeint) that are much higher than our measurements of single-cell migration behavior in Chapter 1, a Brownian dynamics (BD) approach was used to simulate single-cell growth, proliferation, and migration, and compare model assumptions. These studies showed that employing the physically-based assumption that tumor cells occupy volume, an assumption not captured in current reaction-diffusion (RD) simulations, resulted in increased tumor spreading behavior with the same input parameters. Specifically, non-overlapping cells can enter a jammed regime where interior cells are subdiffusive, and peripheral cells become biased outward and superdiffusive in a quasi-ballistic expansion. Thus, we show that, when we account for volume conservation, the relatively low values of diffusion coefficient, such as what was measured in Chapter 1, can generate fast progressing tumors that are similar to RD simulations which use diffusion coefficients much greater than what is observed experimentally for single migrating cells. Therefore, we suggest that cellular jamming behavior contributes to the fast spreading of GBM tumors, and that subsequent simulations of GBM growth should incorporate this assumption so that models are physically grounded and achieve consistency between single-cell behavior and bulk tumor progression. Overall, these studies demonstrate the potential importance of fundamental physical effects in driving tumor progression generally, and glioblastoma specifically.

▼ Prostate cancer (CaP) is a major health problem in males in western countries. Although early-stage CaP can be controlled using conventional therapies, almost all CaP patients invariably progress to recurrent castration resistant CaP and eventually die from secondary disease. Targeting tumour-associated antigens is fast emerging as an area of promise for late stage CaP. This thesis provides an overview of literature regarding CaP-related issues, with emphasis on the putative roles of the tumour microenvironment and selected tumour-associated antigens, i.e.
CD44 and CD147 in CaP. The aims of the study were to: 1) investigate the expression of
CD44 and CD147 in primary CaP tissues and various metastatic CaP cell lines, and identify whether
CD44 and CD147 are related with CaP progression, whether they are related with multidrug-resistance proteins, and whether these two proteins are inter-related; 2) develop CaP cell lines with down-regulated
CD44 and CD147 expression, study the in vitro functions of these molecules in CaP, and the potential mechanisms involved; and 3) develop CaP animal models with
CD44/CD147-knock-down (KD) xenografts, and look at the roles of
CD44 and CD147 in vivo in respect of tumour growth, metastasis, and drug resistance.The results indicated that
CD44 and CD147 are both associated with CaP progression.
CD44 and CD147 are co-expressed and interact in CaP cells. KD of
CD44 or CD147 enhanced docetaxel sensitivity, reduced CaP invasive potential, and down-regulated main signal modulators associated with cell growth and survival. In vivo,
CD44 or CD147-KD PC-3M-luc subcutaneous xenografts showed suppressed tumour growth with increased docetaxel responsiveness compared to control xenografts. Preliminary studies of an intracardiac model showed metastatic spread of PC-3M-luc cells imaged using bioluminescence, indicating this is an appropriate model for future studies assessing the in vivo roles of
CD44 and CD147 in tumour spread. These findings suggest that
CD44 and CD147 are both closely related with CaP metastasis and drug resistance. Selective targeting of
CD44/CD147 alone or combined with docetaxel may limit CaP metastasis and increase chemosensitivity, indicating promise for future CaP treatment. To date, these studies appear to be the first to show that
CD44 and CD147 are collaborators in CaP.

▼ Problem: Über molekulare Mechanismen der
Ausbreitung von Endometriose auf Lymphknoten ist wenig bekannt.
Mittels Genexpressionsanalyse sollen daran beteiligte Gene
identifiziert werden. Methode: RNA-Extrakiton aus Gewebeproben
(Primärläsionen, Lymphknoten mit/ohne Endometriosebefall);
Quanitfizierung der Expression von 28 Genen mittels Real-time PCR;
Immunohistochemie. Ergebnis: Endometriose-spezifische Genprodukte
(z.B. Östrogen- und Progesteronrezeptor) konnten trotz "Verdünnung"
durch Lymphknotengewebe noch klar nachgewiesen werden. CXCR4, CD68,
MKI67 und
CD44 waren in befallenen Lymphknoten deutlich höher
exprimiert. Epitheliale Marker waren in Lymphknoten nur bei
Vorhandensein von manifesten Läsionen nachweisbar, nicht aber in
sog. isolierten Endometriose-ähnlichen Zellen. Diskussion: Die
Ausbreitung von Endometriose auf Lymphknoten ist von einer
differenzierten Genexpression begleitet und scheint Parallelen zu
malignen Transformationen aufzuweisen.

▼ Rheumatoid Arthritis (RA) is an autoimmune disease characterized by inflammation and eventual destruction of the synovial joints. The role of platelets in the pathophysiology of arthritis has only recently been established. Because antibodies to CD44 can deplete platelets, we hypothesized that these antibodies might be effective in arthritis through a platelet-depletion mechanism. We examined the K/BxN passive transfer mouse model of arthritis and found that most antibodies against CD44 were capable of depleting platelets. However, anti-CD44 treatment is effective when administered during developing arthritis, while anti-platelet treatment was not. While CD44 antibodies may be therapeutic through platelet-dependant and independent mechanisms, the ability of CD44 antibodies to decrease platelet counts does not seem to be the critical factor in resolving arthritis in the K/BxN model.

Στην παρούσα διατριβή μελετήσαμε τη χωροχρονική κατανομή των πρωτεογλυκανών versican και
CD44 με τη μέθοδο της RT-PCR και του ανοσοφθορισμού από το στάδιο ΧΙ-ΧΙΙ (μορίδιο) έως το στάδιο ΗΗ16+ (28-29 ζεύγη σωμιτών) και τον ρόλο της versican και της
CD44 με τη χρήση μονοκλωνικών αντισωμάτων έναντι αυτών κατά την ανάπτυξη του πρώιμου εμβρύου.
Η versican είναι πρωτεογλυκάνη θειικής χονδροϊτίνης και αλληλεπιδρά με αυξητικούς παράγοντες, με διάφορες πρωτεΐνες της εξωκυττάριας ύλης και με διαμεμβρανικούς υποδοχείς όπως η
CD44. Τα αποτελέσματα της RT-PCR έδειξαν ότι το mRNA της versican εκφράζεται σε όλα τα αναπτυξιακά στάδια που μελετήσαμε. Ενδιαφέρον παρουσιάζουν τα προϊόντα εναλλακτικής ωρίμανσης της versican που ανιχνεύσαμε ακόμα και στο στάδιο του μοριδίου και που η έκφρασή τους ρυθμίζεται αναπτυξιακά. Η παρουσία του mRNA της versican σε υψηλά επίπεδα στο στάδιο του μοριδίου (ΧΙ-ΧΙΙ) υποδεικνύει ότι το mRNA της versican είναι ωογενετικής προέλευσης στο στάδιο αυτό. Τα πειράματα μας του ανοσοφθορισμού έδειξαν ότι η versican πρωτεΐνη ανιχνεύεται στο στάδιο του μοριδίου και εκφράζεται έντονα στην επιβλάστη και στην υποβλάστη στο στάδιο του προχωρημένου βλαστιδίου (στάδιο ΧΙΙΙ). Στο στάδιο ΗΗ3+ (ενδιάμεσο γαστρίδιο / intermediate streak) παρατηρήσαμε μεγάλη ένταση φθορισμού στα κύτταρα που μεταναστεύουν μέσα από την πρωτογενή αύλακα και στα μεσεγχυματικά κύτταρα που θα σχηματίσουν το μεσόδερμα και το ενδόδερμα. Στο στάδιο ΗΗ4 (προχωρημένο γαστρίδιο / definitive streak) ένταση φθορισμού της versican ανιχνεύθηκε κύτταρα που μεταναστεύουν μέσα από την πρωτογενή αύλακα καθώς και στα κύτταρα που έχουν αρχίσει να σχηματίζουν το μεσόδερμα και το ενδόδερμα. Στο στάδιο που το έμβρυο έχει σχηματίσει 4 ζεύγη σωμιτών (στάδιο ΗΗ8), ανιχνεύσαμε υψηλή ένταση φθορισμού της versican στη νευρική πλάκα και στις νευρικές πτυχές καθώς ανασηκώνονται να σχηματίσουν το νευρικό σωλήνα. Στο στάδιο ΗΗ12 (16 ζεύγη σωμιτών), ισχυρή ένταση φθορισμού της versican ανιχνεύσαμε στο νευρικό σωλήνα, στο γειτονικό του εξώδερμα, στα κύτταρα της νευρικής ακρολοφίας (neural crest), στα κύτταρα του σωμίτη, στο μεσονέφρο και στο γειτονικό του πλάγιο μεσόδερμα που θα σχηματίσει τους μεσονεφρικούς σωληνίσκους. Αργότερα στην ανάπτυξη, ισχυρή ένταση φθορισμού της versican ανιχνεύσαμε επίσης στο διεγκέφαλο, στον οπτικό μίσχο, στο μεσεγκέφαλο, στο μυελεγκέφαλο, στα τοιχώματα του φάρυγγα και της ραχιαίας αορτής, στο ραχιαίο μεσοκάρδιο, στο μυοκάρδιο και στο ενδοκάρδιο, στο μυοτόμο και σκληροτόμο στους σωμίτες, στα τοιχώματα του εντέρου, καθώς και στην εξωκυττάρια ύλη των εμβρυϊκών κοιλοτήτων. Πειράματα σε έμβρυα που εκτέθηκαν στο αντίσωμα έναντι της versican σε διαφορετικά στάδια ανάπτυξης από το μορίδιο ως το προχωρημένο γαστρίδιο έδειξαν ότι η versican πιθανόν να συμμετέχει στα μονοπάτια σηματοδότησης που…

▼ LRP1 est un récepteur d’endocytose multifonctionnel capable non seulement d’interagir avec de nombreux ligands et de réguler leur endocytose, mais également de moduler certaines voies de signalisation intracellulaire. Ce récepteur se révèle implique dans de nombreux mécanismes physiologiques et pathologiques, comme l’athérosclérose, la maladie d’Alzheimer ou encore le cancer. La multiplicité de ses partenaires fait émerger le concept selon lequel LRP1 est capable de réguler le protéome membranaire et ainsi d’influencer le comportement migratoire de nombreuses cellules. De plus, les résultats récents obtenus au sein de notre laboratoire indiquent que ce récepteur d’endocytose est capable de contrôler la dynamique d’adhérence des cellules tumorales. Nous avons donc cherche à identifier un nouveau partenaire membranaire de LRP1, capable de participer à la régulation de l’adhérence tumorale. Notre étude s’est portée sur le récepteur d’adhérence CD44. L’utilisation de RAP, un antagoniste de LRP1 révèle que ce récepteur d’endocytose module la présence de CD44 à la membrane plasmique. Nous avons également découvert que ces deux récepteurs colocalisent fortement dans la cellule tumorale, que ce soit à la surface cellulaire ou au niveau intracellulaire. De plus LRP1 et CD44 co-immunoprécipitent à partir d’extraits totaux et membranaires, indiquant que ces deux récepteurs sont fortement associés au sein d’un même complexe moléculaire. L’étude de la répartition membranaire du complexe LRP1/CD44 a montré qu’il était en grande partie situé dans les radeaux lipidiques et particulièrement les cavéoles. Toutefois ces structures n’apparaissent pas nécessaires à l’établissement du complexe et ne sont pas impliquées dans les processus d’endocytose relatifs à ces récepteurs. En effet, des expérimentations visant à quantifier l’endocytose de CD44 couplées à différents traitements (β-MCD, conditions hyperosmotiques) révèlent que l’endocytose de ce complexe implique principalement la voie des vésicules tapissées de clathrine. Nous avons également démontré que ce mécanisme dynamique permettait de réguler l’adhérence tumorale. Enfin, des travaux sur le shedding de CD44 ont permis d’identifier les protéases impliquées (MT1MMP, ADAMs 10 et 17) et mettent en évidence un effet protecteur de LRP1 sur le clivage de l’ectodomaine de CD44.
The low-density lipoprotein receptor-related protein-1(LRP-1) is a large endocytic recept or mediating the clearance of various molecules from the extracellular matrix. In the field of cancer, LRP1-metiated endocytosis was first associated to anti-properties. However, recent results suggested that LRP-1 may coordinate the adhesion-deadhesion balance in malignant cells to support tumor progression. Here, we observed that LRP-1-silencing or RAP (receptor-associated protein) treatment led to tumor cell surface accumulation of CD44. Moreover, we evidenced a tight interaction between CD44 and LRP-1, not exclusively localized in lipid rafts. Overexpression of LRP-1-derived mini-receptors indicated that the fourth…

▼ In recent years, magnetic nanowires (NWs) have been widely used for their therapeutic potential in biomedical applications. The use of iron (Fe) NWs combines two important properties, biocompatibility and remote manipulation by magnetic fields. In addition the NWs can be coated and functionalized to target cells of interest and, upon exposure to an alternating magnetic field, have been shown to induce cell death on several types of adherent cells, including several cancer cell types. For suspension cells, however, using these NWs has been much less effective primarily due to the free-floating nature of the cells minimizing the interaction between them and the NWs.
Leukemic cells express higher levels of the cell surface marker CD44 (Braumüller, Gansauge, Ramadani, & Gansauge, 2000), compared to normal blood cells. The goal of this study was to functionalize Fe NWs with a specific monoclonal antibody towards CD44 in order to target leukemic cells (HL-60 cells). This approach is expected to increase the probability of a specific binding to occur between HL-60 cells and Fe NWs. Fe NWs were fabricated with an average diameter of 30-40 nm and a length around 3-4 μm. Then, they were coated with both 3-Aminopropyl-triethoxysilane and bovine serum albumin (BSA) in order to conjugate them with an anti-CD44 antibody (i.e. anti-CD44-iron NWs). The antibody interacts with the amine group in the BSA via the 1-Ethyl-3-3-dimethylaminopropyl-carbodiimide and N-Hydroxysuccinimide coupling. The NWs functionalization was confirmed using a number of approaches including: infrared spectroscopy, Nanodrop to measure the concentration of CD44 antibody, as well as fluorescent-labeled secondary antibody staining to detect the primary CD44 antibody. To confirm that the anti-CD44-iron NWs and bare Fe NWs, in the absence of a magnetic field, were not toxic to HL-60 cells, cytotoxicity assays using XTT (2,3-Bis-2-Methoxy-4-Nitro-5-Sulfophenyl-2H-Tetrazolium-5-Carboxanilide) were performed and resulted in a high level of biocompatibility. In addition, the internalization of the coated NWs have been studied by coating them with a pH dependent dye (pHrodoTM Red) that showed a signal once the NWs were internalized by the cell.

▼ Osteoblastic differentiation into osteocytes is regulated in a temporospatial manner. It is difficult to identify which of osteoblasts are at the verge of differentiating into osteocytes; however, podoplanin reportedly localizes to osteoblasts/osteocytes at the verge of differentiating or right after embedding in the bone matrix. In this study, therefore, we attempted to examine the biological function of podoplanin for osteoblastic differentiation into osteocytes. Podoplanin-reactive osteoblasts show dynamic rearrangement of actin filament distribution and show their assembly along the cell membranes and the basal region of the cytoplasmic processes, whereas osteoblasts with little podoplanin immunoreactivity revealed well-developed stress fibers inside the cells. In the metaphysis (the bone remodeling area),
CD44-positive osteoclasts were close to or in contact with podoplanin-reactive osteoblasts showing immunoreactivity of phosphorylated ezrin, an ERM family member associated with actin filament arrangement. Therefore,
CD44-positive osteoclasts may participate in the differentiation of podoplanin-positive/phosphorylated ezrin-reactive osteoblasts into osteocytes. Immunoblotting analysis using calvariae from neonatal mice demonstrated increased phosphorylated ezrin when exogenous
CD44 was administered. On the endosteal surfaces of cortical bones (a modeling area), bone podoplanin-positive osteoblasts were uniformly localized at certain intervals. Although there was no contact with
CD44-positive cells, several osteoblasts showed the immunoreactivities of podoplanin and phosphorylated ezrin. Therefore, unlike femoral trabecules, molecules other than
CD44 may transduce the podoplanin/EMR family signaling in preparation for osteocytic differentiation in the cortical bone. Taken together, the interplay between podoplanin and
CD44 appears to be, at least in part, associated with ezrin phosphorylation and the subsequent actin rearrangement as well as the facilitation of osteoblastic differentiation into osteocytes in metaphyseal trabecules; however, it does not seem to be associated with the cortical bone.

▼ Our laboratory recently reported that treatment with the d-amino acid containing peptide HYD1 induces necrotic cell death in multiple myeloma (MM) cell lines. Due to the intriguing biological activity and promising in vivo activity of HYD1, we pursued strategies for increasing the therapeutic efficacy of the parent linear peptide. These efforts led to the development of a cyclized peptidomimetic, MTI-101, with increased in vitro activity and robust in vivo activity as a single agent using two myeloma models that consider the bone marrow microenvironment. MTI-101 treatment resulted in mechanistically similar hallmarks of HYD1 induced cell death, namely the generation of ROS, depletion of ATP levels, and failure to activate caspase-3. Moreover, MTI-101 was shown to be cross-resistant in the HYD1 acquired resistant H929-60 cell line that was previously developed in our laboratory. In the present study, we pursued an unbiased chemical biology approach using biotinylated peptide affinity purification and LC-MS/MS analysis to identify binding partners of MTI-101. Using this approach, CD44 was identified as a predominant binding partner. Using an ELISA based assay, we showed that biotinylated peptide bound to full length recombinant human CD44 in a concentration dependent manner. Reducing the cell surface expression of CD44 was accompanied by the activation of caspase-3 and cell death was observed in the NCI-H929 and U266 MM cell lines, indicating that MM cells require CD44 expression for survival. Ectopic expression of CD44s correlated with increased binding of the FAM-conjugated peptide in the 8226 MM cell line, and this was further corroborated using CD44 knockout mice which also showed less peptide binding compared to wild-type. However, ectopic expression of CD44s was not sufficient to increase the sensitivity to MTI-101 induced cell death. Mechanistically, we show that MTI-101 induced a pro-survival signal through the activation of Erk1/2 and that CD44 formed a complex with Pyk2. These data corroborate with that of which was previously observed with the parental peptide being a partial agonist and inducing an autophagic survival signal. With respect to cell death, we showed that CD44 forms a complex with known death inducing proteins caspase-8, caspase-10, Rip1, Rip3, Drp1, TNFAIP8, and PGAM5. Furthermore, we demonstrated that MTI-101 induced mitochondrial fission which may be modulated by a Rip1, Rip3 or Drp1 dependent and independent pathway. Finally, we show that MTI-101 has robust activity as a single agent in the SCID-Hu bone implant and 5TGM1 in vivo model of multiple myeloma. Together these data continue to support the further development of this class of compounds as well as identify CD44 as a therapeutic target for the treatment of MM.

▼ Acute myeloid leukemia (AML) is a hematological disorder
characterized by blockage of differentiation of myeloblasts. To date, the
main therapy for AML is chemotherapy. Yet, studies are seeking a better
treatment to enhance the survival rate of patients and minimize the
relapsing of the disease. Since the major problem in these cells is that they
are arrested in cellular differentiation, drugs that could induce their
differentiation have proven to be efficient and of major interest for AML
therapy.
CD44 triggering appeared as a promising target for AML therapy as it
has been shown that specific monoclonal antibodies, such as A3D8 and
H90, reversed the blockage of differentiation, inhibited the proliferation of
all AML subtypes, and in some cases, induced cell apoptosis. Studies
conducted in our laboratory have added strength to these antibodies as
potential treatment for AML. Indeed, our laboratory found that treating HL60 cells with A3D8 shows a decrease in the phosphorylation of the
mammalian target of Rapamycin (mTOR) kinase correlated with the
inhibition of proliferation/induction of differentiation of AML cells.The
relationship between the induction of differentiation and the inhibition of
proliferation and the decrease of mTOR phosphorylation remains to be
clarified.
To study the importance of the de-phosphorylation of mTOR and the
observed effect of CD44 triggering on differentiation and/or proliferation,
we sought to prepare phospho-mimic mutants of the mTOR kinase that will
code for a constitutively phosphorylated form of mTOR and used two main
methods to express this mutant in HL60 cells: lentiviral and simple
transfection (cationic-liposomal transfection).

▼ Acute myeloid leukemia (AML) is a subset of leukemia that is characterized by the clonal expansion of cytogenetically and molecularly abnormal myeloid blasts. These blasts are highly proliferative accumulating in bone marrow and blood which leads to severe infections, anemia, and bone marrow failure. The poor prognosis of AML patients caused by the low tolerance to intensive chemotherapy has encouraged the pursuit of alternative therapeutic approaches. Differentiation therapy which involves the use of agents that can release the differentiation block in these leukemic blasts has emerged as a promising therapeutic approach. The use of All-trans retinoic acid (ATRA) represents a successful example of such an approach, nonetheless its efficacy is restricted to one subtype of AML. Efforts have been focused on finding differentiation agents which are effective for the other more common AML subtypes. Anti-CD44 targeted antibodies that activate the CD44 cell surface antigen are a promising candidate. Previous studies have shown that anti-CD44 treatment has been able to release the differentiation block in AML1 through AML5 subtypes. The exact mechanism by which anti-CD44 treatment is able to induce its effects has not been fully elucidated.
Recent studies highlight the role that epigenetic mechanisms play during haematopoiesis and leukemogenesis and therefore, in this work we investigated the epigenetic mechanisms associated with anti-CD44 induced differentiation. Using AML cell lines from different subtypes, we demonstrated that anti-CD44-induced differentiation results in an extensive change of histone modification levels. We found that inhibiting enzymes responsible for the H3K9ac, H3K4me, H3K9me, and H3K27me modifications, attenuated the anti-proliferative and differentiation promoting effects of antic-CD44 treatment. Taken together, these data highlight the promising potential of using anti-CD44 as a therapeutic agent across multiple subtypes in AML

▼ Des progrès récents dans l’utilisation préclinique et clinique des petits ARN interférents (siRNA) ont montré leur potentiel en tant qu’inhibiteur de la synthèse protéique dans de nombreuses pathologies comme le cancer. L’administration des siRNA rencontre un certain nombre de problèmes liés à leur dégradation rapide dans les milieux biologiques, ainsi qu’à leur difficulté à pénétrer au sein des cellules cibles en raison de leur hydrophilie et de leur charge négative. Une des clés de l’amélioration de l’efficacité thérapeutique de ces molécules repose sur l’emploi de vecteurs. Au cours de cette thèse, des lipoplexes capables de protéger les siRNA contre la dégradation et de favoriser leur transport jusqu’aux cellules cibles ont été développés et optimisés. Pour ce faire, des lipoplexes recouverts d’HA ont été formulés pour la vectorisation active de siRNA vers des cellules tumorales surexprimant le récepteur
CD44. Dans la première partie de cette thèse, la formation des lipoplexes a été étudiée, ainsi que les paramètres influençant leur organisation supramoléculaire. L'insertion de l'HA dans la structure du liposome au moment de la formation des vésicules a entraîné une augmentation de la taille des liposomes en fonction de la concentration d’HA. Leur complexation avec les siRNA a encore augmenté la taille des particules obtenues. L’ajout des acides nucléiques lors de la formation des lipoplexes a provoqué un déplacement d'une partie du conjugué HA-DOPE de la structure des lipoplexes, comme montré par électrophorèse capillaire. La titration calorimétrique isotherme et les études de diffraction des rayons X ont démontré que, sous l’effet des interactions électrostatiques avec les siRNA, un réarrangement des bicouches lipidiques a lieu, conduisant à la formation de vésicules oligolamellaires, confirmé visuellement par cryo-microscopie. Enfin, le positionnement convenable de l’HA sur la surface des lipoplexes et sa capacité de se lier spécifiquement aux récepteurs de
CD44 ont été démontrés par la technique de résonance plasmonique de surface. Dans la deuxième partie de cette thèse, la capture cellulaire et localisation intracellulaire des lipoplexes-HA ont été évalués par cytométrie en flux et microscopie de fluorescence, et ont montré que les lipoplexes modifies par l’HA sont internalisés plus rapidement que les lipoplexes non modifiés, et une fois dans des cellules, ils sont localisés principalement à l’intérieur des endosomes. La capacité des lipoplexes à transporter des molécules de siRNA intactes au cytoplasme a été confirmée par 81 % d'inhibition d'expression de luciferase in vitro sur la lignée cellulaire de cancer du poumon A549-luc. In vivo, le traitement avec les lipoplexes-HA transportant un siRNA anti-luciferase a mené à une diminution statistiquement significative de l’expression de luciferase, ce qui a été confirmé par la réduction de l'expression d’ARNm de la luciferase dans le poumon des animaux traités avec les lipoplexes-HA. L'analyse de la distribution des lipoplexes dans les poumons a montré que les…

▼ L’infection par Helicobacter pylori touche environ la moitié de la population mondiale et est responsable de plusieurs pathologies gastro-intestinales incluant l’adénocarcinome gastrique. Les mécanismes de la carcinogénèse induite par H. pylori ne sont pas clairement élucidés. Mais, l’oncoprotéine CagA que possèdent certaines souches est très impliquée dans la carcinogénèse gastrique ; elle induit l’apparition d’un phénotype particulier, dit colibri, qui mime une transition épithélio-mésenchymateuse (EMT). De plus, CagA déstabilise les jonctions cellulaires en perturbant la E-cadhérine. Les objectifs de ces travaux ont été de déterminer si H. pylori induit une véritable EMT et si cette EMT est à l’origine de l’émergence de cellules souches cancéreuses (CSC). De plus, nous avons étudié le rôle joué par la protéine IQGAP1, protéine assurant le maintien des jonctions cellulaires, dans la carcinogénèse gastrique induite par H. pylori. Ces travaux ont montré que H. pylori induit une EMT in vitro. Cette EMT est à l’origine de l’émergence de cellules CD44high présentant les caractéristiques de CSC. L’étude du rôle de IQGAP1 au cours de la carcinogénèse gastrique liée à H. pylori a permis de déterminer son implication dans l’apparition de lésions néoplasiques dans un modèle de souris transgéniques hétérozygotes pour IQGAP1. En outre, IQGAP1 apparaît comme une protéine dont l’expression est modifiée par l’infection à H. pylori et par l’EMT induite par cette bactérie in vitro. Nos résultats permettent de mieux comprendre le mécanisme physiopathologique de l’adénocarcinome gastrique et seront potentiellement utiles au développement de nouvelles thérapeutiques anti-cancéreuses.
Helicobacter pylori infection is found in about half of the world population and is responsible for several gastrointestinal pathologies, including gastric adenocarcinoma. The mechanisms of the carcinogenesis due to H. pylori remain unclear. However, the link with gastric adenocarcinoma is partly due to the H. pylori CagA oncoprotein. CagA is responsible for a particular cell phenotype in vitro, the “hummingbird” phenotype which corresponds to an elongation of the cells, mimicking an epithelial to mesenchymal transition (EMT). EMT participates to carcinogenesis, and is involved in the generation of cancer stem cells (CSC). Moreover, CagA destabilize the cell junctions. This study aimed to determine wether H. pylori induces a true EMT, and if so, wether this EMT can generate CSCs. The role of IQGAP1, which is a scaffold protein involved in cell adhesion, was also studied in cases of gastric carcinogenesis due to H. pylori. We demonstrated that H. pylori induces an EMT in vitro. Moreover, we showed that this EMT is responsible for the emergence of CD44high cells which have the same characteristics as the CSCs. IQGAP1 has been identified as a protein implicated in neoplastic lesion development in a transgenic mouse model heterozygous for IQGAP1. Moreover, in vitro, the expression of IQGAP1 was modified by H. pylori infection and more specifically by the…

▼ Intrinsisch ungeordnete Proteine (IDP; englisch: intrinsically disordered proteins) liegen als Ensemble von schnell ineinander überführbaren Strukturen vor. Sie nehmen keine stabile tertiäre Struktur an und können einen großen Konformationsraum abdecken. IDPs unterscheiden sich jedoch insofern von denaturierten Proteinen, als dass sie bestimmte kompakte energetisch bevorzugte Zustände einnehmen können. Der Grad an Unordnung bzw. Verdichtung ist in ihrer Primärstruktur codiert, welche evolutionär auf gewisse molekulare Eigenschaften und deren spezielle Funktionen optimiert wurde. Insbesondere das Fehlen einer stabilen Struktur verleiht IDPs ein Explorationsverhalten, um an einer Vielzahl von Wechselwirkungen teilzunehmen. Aufgrund ihrer Fähigkeit zu posttranslationalen Modifikationen und/oder Spleißvarianten bieten IDPs Modularität und Anpassungsfähigkeit an zahlreiche biologische Prozesse. Deshalb inszenieren intrinsisch ungeordnete Bereiche oft die Signalketten in eukaryotischen Zellen. Tatsächlich stehen das abnormale Verhalten von IDPs unter anderem auch mit Krebserkrankungen und neurodegenerativen Erkrankungen in Zusammenhang.
In dieser Arbeit lege ich ein besonderes Augenmerk auf das mit Metastasen assoziierte Protein Osteopontin (OPN). OPN dient dabei als ein typisches IDP; es liegt größtenteils ungeordnet vor mit einem zentralen verdichteten Zustand, der für die richtige Anordnung der wechselwirkenden Motive des Proteins verantwortlich ist. OPN ist ein extrazelluläres Protein, das mit verschiedenen Komponenten der extrazellulären Matrix (EZM) und mit zwei Familien an Membran-Rezeptoren wechselwirkt, Integrine und CD44. Das Ziel ist die Charakterisierung (i) der für die Verdichtung des IDPs entscheidenden Sequenzen, mit besonderem Augenmerk auf die Relevanz von Prolinen; (ii) des Evolutionsdrucks, bestimmte Eigenschaften von OPN-Homologen zu konservieren; (iii) der strukturellen Neuanordnung bei der Bindung an EZM-Partner sowie auch deren Membran-Rezeptoren; (iv) der Auswirkung von Phosphorylierung auf Strukturdynamik und Bindung; und (v) der ungeordneten Bereiche von CD44 und deren Bindung an OPN.
Schnelle lokale Bewegungen der Polypeptidketten machen IDPs zu hervorragend geeigneten Systemen, die mit Kernspinresonanz-Spektroskopie (NMR; englisch: nuclear magnetic resonance) in Lösung untersucht werden können. Verschiedene Methoden wurden entwickelt um die Problemstellungen anzugehen. Diese reichen von maßgeschneiderten 13C-detektierten Experimenten und ein neues Protokoll, um die Synergie zwischen NMR und Zellbiologie zu nutzen und die Bindung von OPN an lebende Zellen zu charakterisieren.
Intrinsically disordered proteins (IDPs) exist as an ensemble of rapidly interconverting structures. They do not adopt a stable tertiary structure and explore a large conformational space. However, IDPs differ from denatured proteins in the sense that they probe some energetically favourable compact states. The degree of ‘disorder’ or compaction is encoded in their primary sequence, which has evolved to provide certain…

▼ Le cancer gastrique (CG) est une maladie multifactorielle, fréquemment associée à l’infection chronique par des souches CagA+ d’Helicobacter pylori. La transition épithélio-mésenchymateuse (EMT) est un processus réversible dans lequel une cellule épithéliale polarisée acquiert un phénotype mésenchymateux. L’EMT est à l’émergence de cellules souches cancéreuses (CSC) qui expriment
CD44 et présentent une activité ALDH élevée. L’infection des cellules épithéliales gastriques humaines (CEGs) par CagA+ H. pylori induit des cellules
CD44+ avec des propriétés des CSCs via une EMT. La voie Hippo est composée par les kinases MST et LATS, et leurs cibles, les YAP1 et TAZ. Suite à la phosphorylation, YAP1 et TAZ sont inhibés. YAP1 et TAZ activés lient les facteurs TEAD pour promouvoir la croissance cellulaire et l’inhibition de l’apoptose.Notre premier objectif était de rechercher si H. pylori change l’état d’activation de la voie Hippo et l'effet sur l’EMT et les CSC in vitro et in vivo. Le deuxième but est la caractérisation du rôle de YAP1/TEAD dans les propriétés de CSCs gastriques in vitro et les conséquences de son inhibition dans la croissance tumorale in vivo.Pour étudier la régulation de la voie Hippo pendant l’infection par H. pylori, LATS2, YAP1 et
CD44 ont été évalués dans la muqueuse gastrique de sujets non-infectés et infectés par H. pylori, qui ont été augmentés avec l’infection et leur surexpression a été associée avec la gastrite et la métaplasie intestinale. Dans les CEGs l’expression de gènes de la voie Hippo a été altérée par l’infection. La régulation de la voie Hippo par H. pylori a une cinétique diphasique et dépendante de CagA. Dans l’infection précoce, H. pylori déclenche l’activité transcriptionelle de YAP1. Cette période d’inactivité de la voie Hippo est suivi de son activation progressive, soutenue par l’accumulation de LATS2 et la phosphorylation inhibitrice de YAP1. La répression de LATS2 avec siRNAs a accéléré l’acquisition du phénotype mésenchymateux après l’infection, l’augmentation de marqueurs de l’EMT (Zeb1 et Snail1), et la diminution des miR-200 épithéliaux. Les CSC induites par H. pylori ont été potentialisées par l’inhibition de LATS2, ce qui suggère que LATS2 limite l’EMT et le phénotype de CSC acquis pendant l’infection. L’inhibition de LATS2 ou YAP1 diminue l’expression de ces deux protéines, révélant ainsi une boucle de régulation positive. Dans des coupes de tissu de CG, l’expression de LATS2 et YAP1 est hétérogène et positivement corrélée, fait qui a été confirmé dans 38 CEGs de la CCLE. L’expression LATS2 est fortement corrélée à celle de CTGF et CYR61, ce qui suggère que LATS2 peut aussi être un gène cible de YAP1/TEAD.La verteporfine (VP) est capable d’interrompre l’interaction YAP1/TEAD, et donc d’inhiber son activité transcriptionelle. In vitro, utilisant CEGs et des cellules de tumeurs de patients amplifiées chez la souris (patient-derived xenograft PDX), le traitement à la VP a diminué la croissance cellulaire, l’expression de gènes cible de YAP1/TAZ/TEAD, l’activité du…

▼ Tumores sÃo populaÃÃes celulares heterogÃneas hierarquicamente organizadas, cujas cÃlulas-tronco possuem importÃncia relevante desde que sÃo cÃlulas com a capacidade de se renovarem e de gerarem linhagens em fases diferentes. Dada a sua importÃncia, a
identificaÃÃo de componentes de cÃlulas-tronco à essencial para o entendimento da tumorigÃnese. Apesar de marcadores de linhagem neural terem sido identificados, a associaÃÃo destes marcadores com os tumores cerebrais ainda à escassa e nos astrocitomas sÃo relacionados principalmente aos glioblastomas. Entre esses marcadores de cÃlulas-tronco,CD133, CXCR4 e
CD44 sÃo relacionados à formaÃÃo do glioma, migraÃÃo e crescimento; por outro lado, OLIG2 à envolvido no destino celular. NÃo existem estudos, atà essa data, que avaliam todos esses marcadores juntos e sua relaÃÃo com grau tumoral. Adicionalmente, alteraÃÃes epigenÃticas especÃficas, especialmente a metilaÃÃo em promotor, tem sido identificadas nestes tumores, levando a inativaÃÃo de genes, com destaque o CDKN2A (proteÃna p16INK4A), um supressor tumoral. Apesar de esse mecanismo ser apontado como o principal inativador desse gene, em astrocitomas ainda existem questÃes controversas. Para avaliar essas questÃes, este estudo objetivou determinar a expressÃo e padrÃo de metilaÃÃo em promotor de CDKN2A e sua associaÃÃo com parÃmetros clinico-patolÃgicos e se a presenÃa de cÃlulas-tronco/progenitoras, considerando a expressÃo de CD133, CXCR4,
CD44 e OLIG2 poderia definir subpopulaÃÃes de cÃlulas que podem ser usadas como marcadores prognÃsticos. Para isso, em uma sÃrie de 93 astrocitomas de diferentes graus de malignidade, foram estudadas a expressÃo dos marcadores CD133, CXCR4,
CD44, OLIG2 e p16INK4A, detectada pela tÃcnica de imunohistoquÃmica, e o padrÃo de metilaÃÃo em promotor de CDKN2A, por PCR especÃfico para metilaÃÃo (PCR-MS). Os dados foram entÃo associados com grau tumoral, localizaÃÃo e outros parÃmetros clinico-patolÃgicos. As anÃlises estatÃsticas foram realizadas usando o teste do X2, teste exato de Fisher, correlaÃÃo de Spearman, agrupamento de k-means e anÃlise de componentes principais, com diferenÃas consideradas significantes com p<0.05. A imunomarcaÃÃo de OLIG2 mostrou a frequÃncia maior de positividade (73,1%), seguido por CXCR4 (60,2%),
CD44 (55,9%) e CD133 (45,2%). AnÃlises de correlaÃÃo e agrupamento definiram dois subtipos de populaÃÃo de acordo com os marcadores estudados, um subtipo CXCR4(+)CD133(+)
CD44(+) e outro OLIG2(+). Tumores CD133, CXCR4 e
CD44 positivos aumentaram de acordo com malignidade. No grau IV, este subtipo de tumores [CD133(+)CXCR4(+)
CD44(+)] foi significantemente mais frequente (p=0,008) e tambÃm nos tumores difusos. Adicionalmente, tumores com CXCR4(+) e CD133(+) foram preferencialmente localizados nos hemisfÃrios cerebrais e nos ventrÃculos, e a maioria nos pacientes com idade ≥ 30 anos. Por outro lado, tumores OLIG2(+) foram associados com o cerebelo, que à a localizaÃÃo preferencial do astrocitoma pilocÃtico. Uma forte correlaÃÃo negativa entre imunomarcaÃÃo nuclear…

▼ Sabemos hoje que os tumores sólidos apresentam uma composição celular heterogênia e que apenas uma pequena parcela dessas células apresenta capacidade de se proliferar e gerar novos tumores. Estudos prévios sobre a formação do câncer de mama têm sido realizados com base na combinação dos marcadores de superfície celular CD44 e CD24. Já foi demonstrado que uma subpopulação de células do câncer de mama com alta expressão de CD44 e baixa expressão de CD24 (CD44+/CD24-) tem maior capacidade de gerar tumores, quando comparadas com a subpopulação de células CD44-/CD24+. O objetivo do estudo foi identificar a taxa de células com fenótipo CD44+/CD24- presentes nos tumores mamários e relaciona-la com a taxa de comprometimento dos linfonodos axilares ipsilaterais por neoplasia, além de avaliar também sua relação com outros fatores sabidamente relacionados com mal prognóstico da paciente. Pacientes e métodos: avaliamos prospectivamente 53 amostras cirúrgicas provenientes de 42 pacientes com diagnóstico histopatológico de carcinoma de mama, quantificando as células CD44+/CD24- por citometria de fluxo. Relacionamos a porcentagem destas células encontrada em cada amostra com o comprometimento axilar, os receptores hormonais e Her-2, a idade da paciente, o grau histológico do tumor, o diâmetro patológico do tumor e o tipo histológico. Resultados: verificamos um significante aumento da população de células CD44+/CD24- no grupo de carcinomas ductais invasivos em pacientes que apresentavam metástase axilar [mediana 8,53% (3,6 71,2%)] em relação ao grupo de pacientes sem linfonodos comprometidos pela neoplasia [mediana 1,49% (0,3 17,1%)] (p=0,0002). Conclusão: concluímos então que quando estudamos vários tumores mamários invasivos de mesma classificação histológica, podemos notar que existe uma variação na quantidade de células CD44+/CD24- entre eles. Nosso estudo mostrou que essa variação está relacionada à agressividade tumoral e à sua capacidade de gerar metástases já que, tumores com maior quantidade de células CD44+/CD24- apresentam maior taxa de comprometimento dos linfonodos axilares.
It is known that solid tumors are composed by a heterogeneous combination of cells and only a small portion of these cells has the capacity to proliferate and generate new tumors. Previous studies about the breast cancer initiation have been based on a combination of CD44 and CD24cell surface markers. It has been shown that this subpopulation of breast cancer cells with high expression of CD44 and low expression of CD24 (CD44+/CD24-) has a greater capacity to generate tumors when compared with the subpopulation of cells CD44- /CD24+. The study objective was to identify whether the rate of cells with CD44+/CD24- phenotype present in breast tumors is related with the rate of ipsilateral lymph node metastasis, in addition to evaluate its relationship with other risk factors known to be related with worst prognosis. Patients and methods: we prospectively evaluated 53 surgical specimens from 42 patients with histological diagnosis of breast cancer,…

▼ Colon cancer comes third worldwide in men and fourth in women. During progression to colon cancer, the first disorder observed is the increase of the cells number (hyperplasia) at the intestinal epithelial surface. As a result, adenomas formed increase in size and number, without invading in neighboring structures. Some of the adenomas can become in situ cancer and finally invasive cancer. Extracellular matrix surrounds the cells and supports their growth into the tissues. Particularly, the molecules of the extracellular matrix interact with the cells, signal them and affect important cellular functions, such as recognition between cells, cell adhesion, migration, proliferation and differentiation. In cancer, structural changes take place in the synthesis and degradation of the extracellular matrix, leading to increased deposition of molecules in the matrix. As normal cells become cancerous, the extracellular matrix is modified in such a way that promotes the secretion of molecules, which further promote the growth of cancer cells and promote processes such as filtration and metastasis. The extracellular matrix, therefore, is one that provides in tumor cells survival signals, such as proliferation, motility, infiltration and metastasis. Hyaluronan is a main component of the extracellular matrix, which participates in a variety of molecular functions, which contribute both to structural features of the tissue and on the cell behavior during the formation or reorganization of tissues. Most cancers are characterized by an increased accumulation of hyaluronan. In most normal biological processes, large molecules of hyaluronan are usually found, whereas in cancerous conditions small molecules of hyaluronan are mostly found, which are considered to facilitate the mobility of cancer cells and infiltration. In the production of molecules of hyaluronan, its biosynthetic enzymes play catalytic role, hyaluronan synthases (HAS1, HAS2, HAS3), and its catabolic enzymes, hyaluronidases (Hyal-1, -2, -3, PH-20). The three synthases, while they have high homology in their sequence, they differ in the sizes of synthesized molecules. Hyaluronidases have also high degree of homology, they are transcriptionally active and their expression depends on the type of tissue in which they are expressed. During tumor development differential expression of synthases is observed and the transcriptional regulation of genes allows the cells to modulate the extracellular environment so as to favor tumor growth and metastasis. Additionally, numerous studies show differential hyaluronidase expression in cancer, which suggests that cancer cells use hyaluronidase to cleave hyaluronan in tissues and thereby facilitate tumor invasion. Furthermore, loss of hyaluronolytic activity leads to accumulation of hyaluronan that may be one of the steps required by the cells during carcinogenesis. All these molecules are involved in hyaluronan metabolism and in the reorganization of the extracellular matrix, in cell-extracellular matrix interactions and are likely…

▼ Acute myeloid leukemia (AML) is a heterogeneous disease characterized by the accumulation of immature nonfunctional highly proliferative hematopoietic cells in the blood, due to a blockage in myeloid differentiation at various stages. Since the success of the differentiation agent, All-trans retinoic acid (ATRA), in the treatment of acute promyelocytic leukemia (APL), much effort has gone into trying to find agents that are able to differentiate AML cells and specifically the leukemic stem cell (LSC). CD44 is a cell surface receptor that is over-expressed on AML cells. When bound to anti-CD44 monoclonal antibodies (mAbs), this differentiation block is relieved in AML cells and their proliferation is reduced. The molecular mechanisms that AML cells undergo to achieve this reversal of their apparent phenotype is not fully understood. To this end, we designed a study using quantitative phosphoproteomics approaches aimed at identifying differences in phosphorylation found on proteins involved in signaling pathways post-treatment with CD44-mAbs. The Rho family of GTPases emerged as one of the most transformed pathways following the treatment with CD44-mAbs. The P21 activated kinase 2(PAK2), a target of the Rho family of GTPases, was found to be differentially phosphorylated in AML cells post-treatment with CD44-mAbs. This protein has been found to possess a role similar to that of a switch that determines whether the cell survives or undergoes apoptosis. Beyond confirming these results by various biochemical approaches, our study aimed to determine the effect of knock down of PAK2 on AML cell proliferation and differentiation. In addition, over-expression of PAK2 mutants using plasmid cloning was also explored to fully understand how levels of PAK2 as well as the alteration of specific phospohorylation sites could alter AML cell responses to CD44-mAbs. Results from this study will be important in determining whether PAK2 could be used as a potential therapeutic target for AML once its levels are altered.

▼ Ovarian carcinoma has poor prognosis with a high mortality rate in gynecologic malignancy. The epithelial ovarian cancers account for 90% of ovarian malignancy. They have been considered arising from the surface epithelium covering the ovary. The major types of epithelial ovarian cancers include serous, endometrioid, mucinous and clear cell carcinomas.
DLK-1(Delta-Like 1 Homolog) is a transmembranous and secreted protein belonging to the epidermal growth factor-like homeotic family. Although expressed widely during embryonic development, only few types of tissue retain DLK-1 expression in adults. DLK-1 plays important roles in regulating cell differentiation, such as adipogenesis and osteogenesis. Aberrant expression of DLK1 has been found in various types of human cancers, including neuroblastoma, hepatocellular carcinoma, glioma and prostate cancer, but its expression in ovarian cancer has not yet been studied.
CD44 is known as a stem cell marker. Previous studies showed that
CD44 expressed higher level in ovarian cancer tissues and has been identified as a biomarker of ovarian carcinoma. Vimentin is a type III intermediate filament protein that is widely expressed in mesenchymal tissue, and is considered an important marker for epithelial-mesenchymal transition (EMT). E-cadherin is widely expressed in epithelial cells and acts as a pivotal tumor suppressor. Loss of E-cadherin expression has been known to be involved in epithelial-mesenchymal transition.
This study was aimed to discover the significance of DLK-1 expression and its correlation with tumor stemness and EMT in various types of epithelial ovarian cancer. The expression of DLK-1,
CD44, vimentin and E-cadherin were analyzed in 283 ovarian carcinomas by immunohistochemistry on tissue microarray. The result showed positive correlation among DLK-1,
CD44 and Vimentin expressions (P ï¼ 0.01). Although there was no statistical significance (P ï¼ 0.237), a reversed correlation was noted between the expressions of DLK-1 and E-cadherin in ovarian carcinomas. Our study revealed that DLK-1 is overexpressed in epithelial ovarian cancers, especially in endometrioid carcinoma.
In summary, DLK-1 may correlate with EMT and tumor stemness of ovarian carcinoma. Further study is needed to assess the potential use of DLK-1 for therapeutic strategy and prognosis evaluation.

▼ Salivary gland neoplasms exhibit a wide variety of biological behavior and a high
morphological diversity raises the interest in researching these lesions. The stem cells are the
main source for the generation and maintenance of cell diversity, disorders in the regulation of
these cells can lead to the production of altered stem cells, termed cancer stem cells capable of
generate the tumor. Researches on cancer stem cells and associated proteins have been
developed in some oral cancers; however, their role in salivary gland neoplasms is not well
established. Thus, the aim of this study was to identify the tumor parenchyma cells exhibiting
stem cell characteristics, by evaluating the immunoreactivity of OCT4 and
CD44, in a number
of cases of salivary gland neoplasms. The sample consisted of 20 pleomorphic adenomas, 20
mucoepidermoid carcinomas and 20 adenoid cystic carcinoma located in minor and major
salivary glands. The expression of OCT4 and
CD44 was evaluated by the percentage of
positive cells (PP) and the intensity of expression (IE), it is realized the sum of the scores,
resulting in the total score immunostaining (PIT) ranging 0-7. All studied cases showed
positive expression of OCT4 and
CD44 and higher values than the control groups. It was
observed that for OCT4 luminal cells and non-luminal were immunostained in the case of
pleomorphic adenomas and adenoid cystic carcinoma. Already the immunoreactivity of
CD44
was particularly evident in the non-luminal cells of these lesions. In mucoepidermoid
carcinomas for both markers, there was immunoreactivity in squamous and intermediate cells
and absence of staining mucous cells. For both markers, a statistically significant higher
immunostaining was verified in neoplasms located in the major salivary glands compared
with lesions in the minor salivary (p<0.001). At the total sample and in the group of minor
salivary glands, malignant neoplasms exhibited higher immunoreactivity for OCT4 than
pleomorphic adenoma. However, there was no statistically significant difference between the
lesions and between their classifications histomorphologic. Analyzing the correlation between
OCT4 and
CD44 immunoexpressions, a statistically significant moderate positive correlation
(r = 0.444) was observed. The high expression of OCT4 and
CD44 may indicate that these
proteins play an important role in identifying cancer stem cells, allowing a prediction of
biological behavior of salivary gland neoplasms.

▼ Τα μηνιγγιώματα αποτελούν ιδιαίτερα συχνούς όγκους του Kεντρικού Νευρικού Συστήματος, όχι όμως επαρκώς μελετημένοι. Στην πλειοψηφία τους είναι καλοήθεις όγκοι (WHO grade I), όμως το 10% όλων των μηνιγγιωμάτων εμφανίζουν κακοήθη χαρακτηριστικά, όπως διήθηση των παρακείμενων ιστών, αυξημένα ποσοστά υποτροπής μετά από εξαίρεση, κ.α. Το σηματοδοτικό μονοπάτι Hippo είναι ένα διατηρημένο εξελικτικά μονοπάτι που εμπλέκεται σε διαδικασίες ρύθμισης του μεγέθους των οργάνων, κυτταρικού πολλαπλασιασμού, διαφοροποίησης και ανάπτυξης καρκίνου. Λίγα είναι γνωστά όσον αφορά το ρόλο του Hippo μονοπατιού στα μηνιγγιώματα.
Σκοπός της παρούσας εργασίας είναι η μελέτη του Hippo μονοπατιού στα χαμηλής και υψηλής κακοήθειας μηνιγγιώματα.
Χρησιμοποιήθηκαν 53 δείγματα από εξαιρεθέντα μηνιγγιώματα, 34 χαμηλής κακοήθειας και 19 υψηλής κακοήθειας, τα οποία μελετήθηκαν ανοσοϊστοχημικά ως προς την έκφραση των παραγόντων του Hippo CD44, YAP και TAZ.
Παρατηρήσαμε στατιστικά σημαντική συσχέτιση μεταξύ της έκφρασης των CD44, ΥΑΡ και ΤΑΖ. Υπήρχε στατιστικά σημαντική συσχέτιση μεταξύ του βαθμού κακοήθειας και της έκφρασης των παραπάνω μορίων. Παρατηρήθηκε στατιστικά σημαντική διαφορά στην πυρηνική εντόπιση των ΥΑΡ και ΤΑΖ μεταξύ των υψηλής και χαμηλής κακοήθειας μηνιγγιωμάτων.
Βάσει των παραπάνω αποτελεσμάτων, συμπεραίνουμε ότι το σηματοδοτικό μονοπάτι Hippo είναι απενεργοποιημένο στα υψηλής κακοήθειας μηνιγγιώματα με αποτέλεσμα οι μεταγραφικοί συνενεργοποιητές ΥΑΡ και ΤΑΖ να δρουν στον πυρήνα προάγοντας τον κυτταρικό πολλαπλασιασμό και διαδικασίες αντιαπόπτωσης. Αυτό, είναι ίσως εφικτό μέσω της δράσης του CD44 που αλληλεπιδρά με την μερλίνη, upstream ρυθμιστής του μονοπατιού. Απαιτούνται περαιτέρω μελέτες για τη διευκρίνηση του ακριβούς μηχανισμού.
Meningiomas are among the most common primary tumors of the Central Nervous System, but relatively understudied. The majority of meningiomas are benign tumors (WHO grade I), but almost 10% of all diagnosed meningiomas exhibit malignant features, such as invasiveness to the surrounding brain tissue, high recurrence rate, etc. Hippo signaling pathway is an evolutionary highly conserved protein kinase cascade involved in organ size control, cell proliferation and apoptosis, differentiation and cancer development. Very few are known about the role of Hippo pathway and meningiomas.
In this study we attempt to find out whether Hippo path functions differently between high and low grade meningiomas.
For this purpose paraffin embedded tissues obtained from 53 patients who underwent surgical removal of meningiomas were examined histoimmunologicaly. 34 out of 53 cases were low grade meningiomas and 19 out of 53 were high grade meningiomas. The paraffin sections were immunostained with CD44, YAP and TAZ antibodies, components of the Hippo signaling pathway.
We observed statistically significant association between the expression of CD44, YAP and TAZ. There was a significant correlation between high grade meningiomas and expression of the examined factors. Moreover there was a significant difference in…

▼ The Bowman-Birk inhibitors (BBI) are protein molecules containing two distinct inhibitory domains for trypsin and chymotrypsin-like enzymes. The interest for this class of inhibitors is based on studies which demonstrated a protective effect promoted by BBI, particularly for chemically-induced cancers. In the present work, we evaluated the effects of BBI isolated from Macrotyloma axillare and Glycine max in the prevention of colon cancers induced by intraperitoneal injections of dimethylhydrazine (DMH) during 12 weeks. Control and DMH-treated animals were fed a diet containing BBI at a dose of 0.1% (p/p) associated (DMHV) or not with the vitamins A, C and E, during 24 weeks. DMH-treated animals exhibited hystopathological alterations compatible with the formation of neoplastic polyps. In agreement with the hystological examinations, analysis of the tumor marker CD44, by Western blotting, revealed a significant increase in its expression for the DMH-treated group. Protein extracts from these tissues also contained increased proteasome-dependent proteolytic activity as judged by peptidase assays for the trypsin and chymotrypsin-like activities. In contrast, for DMH + BBI-treated animals proteasomal activity was comparable to that observed for the control group. In fact, animals given BBI alone, as a diet supplement, exhibited decreased proteasomal activity when compared to that from animals fed a normal diet. In addition, by using a sepharose-BBI affinity column, it was observed retention of enzymes displaying trypsin and chymotrypsin-like activities obtained from the lysosomal and soluble fractions. These proteolytic activities were also shown to be increased for DMH-treated animals. These results suggest that the inhibition of distinct proteolytic activities could account for the protective mechanisms produced by BBI. Collectively our analyses allowed us to conclude that BBI treatment was able to prevent intestine polyp formation, decrease any associated inflammatory processes and keep at basal levels the classic tumor marker CD44.
Os inibidores do tipo Bowman-Birk (BBI) são moléculas protéicas contendo dois domínios inibitórios distintos para enzimas semelhantes à tripsina e quimotripsina. O interesse por essa classe de inibidores decorre de estudos que demonstraram o efeito protetor dos BBI no câncer induzido quimicamente. No presente trabalho avaliou-se o efeito dos BBI isolados de Macrotyloma axillare e Glycine max na prevenção de neoplasias colo-retal induzidas por injeções intraperitoneais de dimetilhidrazina (DMH) durante 12 semanas. Os grupos de camundongos controle e testes (tratados com DMH) receberam uma dieta contendo BBI, na dose de 0,1% (p/p) associada (DMHV) ou não às vitaminas A, C e E, durante 24 semanas. Camundongos tratados com DMH apresentaram alterações histopatológicas compatíveis com a formação de pólipos neoplásicos. Em concordância com a histologia, a análise do marcador tumoral CD44, por Western blotting, revelou aumento significativo de expressão nos animais tratados com DMH e DMHV. Os…

▼ Ceramide is a bioactive sphingolipid that is capable of inducing apoptosis in mammalian cells. However, the role of ceramide in cancer metastasis remains largely unexplored. In this dissertation, I have demonstrated that ceramide induces anoikis, inhibits extravasation, and blocks the epithelial-mesenchymal transition (EMT) in metastasis-competent human breast cancer cell lines. Mechanistically, the effects of ceramide on anoikis and extravasation are mediated by lysosomal degradation of
CD44, independent of palmitoylation or proteasome targeting. SiRNA down-regulation of
CD44 mimics ceramide-induced anoikis and diminished extravasation of cancer cells. On the other hand, the ability of ceramide to prevent IL-6-induced EMT is dependent on its ability to inhibit STAT3 activation. Taken together, the data in this dissertation indicate that ceramide limits
CD44-dependent breast cancer cell migration and IL-6/STAT3-dependent EMT, suggesting that ceramide analogs could be used to prevent and treat solid tumor metastasis.

▼ As Síndromes Mielodisplásicas (SMD) representam um grupo de doenças clonais da célula pluripotencial hematopoiética caracterizadas por hematopoiese ineficaz e aumento do risco de progressão para Leucemia Mieloblástica Aguda. Considerando que a linha eritróide está muitas vezes afectada em SMD e a avaliação da displasia desta linha representa um desafio na análise imunofenotípica de medulas mielodisplásicas, o objectivo deste trabalho foi estudar a expressão de
CD44 e de CD35 na maturação eritróide normal e a forma como essa expressão é afectada em SMD.
Este estudo foi efectuado em 16 amostras de medula óssea (MO) normais/reactivas e em 48 amostras de MO de indivíduos diagnosticados com SMD e sem tratamento. De acordo, com a Organização Mundial de Sáude (OMS) os doentes com SMD foram classificados em CRDM (n=20), AREB-1 (n=15) e AREB-2 (n=13) e de acordo com o International Prognostic Scoring System (IPSS) em Baixo risco (n=5), Intermédio-1 (n=8) e Intermédio-2 e Alto risco (n=14). A caracterização imunofenotípica foi efectuada através de um protocolo de imunofluorescência directa de marcação-lise-lavagem, utilizando os anticorpos monoclonais: anti-CD34; anti-HLA-DR; anti-CD117; anti-
CD44; anti-CD35; anti-CD45, anti-CD123 e anti-CD133. Para a análise, procedeu-se à identificação e quantificação das células de linha eritróide em MO total e nos diferentes estádios de maturação e à avaliação da expressão de
CD44 e de CD35.
Os resultados deste estudo revelaram o CD35 como um marcador precoce na diferenciação eritróide normal e um aumento da expressão de
CD44 e da percentagem de eritroblastos em SMD, sendo este aumento mais evidenciado nos estádios mais avançados da doença.

▼ This project focused on the design of a cellular
scaffold applicable for the promotion of peripheral nerve
regeneration. Firstly, we established a correlation between the
organization of HA/PEG co-polymeric networks to their mechanical
and degradability properties; cell adhesion was conferred to all
gels by the incorporation of RGD peptides. Three families of
hydrogels were produced using different procedures to permit an
increasing physical incorporation of HA into a PEGDA-based network.
From a comparative study of rheological properties and enzymatic
degradability, co-networks obtained using thiolated HA as chain
transfer agent during PEGDA photo-polymerization were selected for
further biological investigations, aiming to link the cellular
response of L929 murine fibroblasts (phenotype, proliferation rate,
metabolic activity) to the composition and the consistency of
selected hydrogels. Our findings showed that there is a clear
relation between increasing hardness and increasing cell
spreading/proliferation rate. This study illustrated the
possibility to fine tune cell/material interactions with
appropriate reactive processing techniques.As a spin-off of this
study, we become interested in the interplay of cellular
interactions in the use of materials that contain both HA and RGD
peptides, which can bind at the same time to HA receptors such as
CD44 and av integrins. We focused on soluble HA derivatives, with
or without dandling RGD peptides. The kinetics and the mechanistic
details of both HA and HA-RGD internalization were studied in a
phagocytic model (J774.2 murine macrophages). HA-RGD showed a form
of synergic binding to integrins and
CD44 (HA receptor), whereas
its uptake remained solely regulated by
CD44 dwell-time on the cell
membrane. This study demonstrated that the knowledge of the
rate-determining steps of the uptake of a carrier is necessary for
assessing its efficiency. In this case, the presence of multiple
ligands on a carrier was beneficial in some respect, but may not be
optimal to overcome internalization limitations that arise from the
slow turnover of the determining receptor.Finally, we studied the
relation between the regulation of the expression of
CD44 / RHAMM
(HA receptor mediated motility) and the motility of Schwann cells
(peripheral glial cells) and stem cells differentiated into a glial
phenotype. Rt-PCR and immuno-assay experiments suggested that RHAMM
up-regulation is associated with glial differentiation and we
speculate that in the future this HA receptor could be considered
as a differentiation marker. We also illustrated the importance of
HA / RHAMM interaction for the motility of glial cells. These
results indicate the importance of HA in mediating glial cell
function during peripheral nerve regeneration and have implications
