▼ High mobility group box 1 (HMGB-
1) protein is a non-histone chromosomal protein. As a DNA binding protein, HMGB-
1 is involved in the maintenance of nucleosome structure, regulation of gene transcription and it is active in DNA recombination and repair. It has been known that HMGB-
1 is a late mediator of endotoxemia and sepsis. HMGB-
1 is released from activated macrophages, induces the release of other proinflammatory mediators, and mediates cell death when overexpressed.
We speculated that the course of sepsis maybe different without the involvement of HMGB-
1. The aims of this study are to investigate the role of HMGB-
1 in mediating sepsis and to observe the effects by using RNAi to affect the production of HMGB-
1. Lipopolysaccharide (LPS) was used to simulate sepsis in culture as well as stimulate the release of HMGB-
1 from RAW 264.7 cells. Levels of HMGB-
1 in the culture medium were subsequently measured by Western blot. Other proinflammatory cytokines (TNF-α, IL-6 and TGF-β) were measured by ELISA. HMGB-
1 could not be detected in the culture medium in the absence of LPS stimuli, but after 0.5 μg/ml LPS treatment HMGB-
1 release could be detected. HMGB-
1 the amount of released from LPS activated RAW 264.7 cells was in a time- and dose-dependent manner. The present study demonstrated that RNAi in the treatment of LPS-stimulated RAW264.7 cells resulted in the blockade of HMGB-
1 and decreased LPS-induced inflammatory response. The results demonstrated that HMGB-
1 plays a pivotal role in macrophage inflammatory responses by modulating the production of inflammatory mediators.

▼ Asthma is a chronic disorder highlighted by intermittent airway inflammation and characterized by paroxysmal dyspnea and airway hyperresponsiveness (AHR). A key feature of severe asthma is the development of airway wall remodeling, which is thought to occur through repeated rounds of inflammation and tissue repair. Remodeling includes structural changes such as increased mass of airway smooth muscle (ASM), and excessive collagen deposition. ASM cells contribute to airway remodeling via the expression and secretion of extracellular matrix (ECM) proteins. This is particularly driven by inflammatory processes, which include mediators such as transforming growth factor (TGF)-β
1 and damage associated molecular pattern (DAMP) proteins, such as
high mobility group box 1 (
HMGB1).
HMGB1 is ubiquitously expressed as a non-histone DNA-binding protein that can regulate gene expression, but can also be released in response to stress to underpin inflammation and tissue repair. In this study we tested the hypothesis that extracellular
HMGB1 induces signaling pathways that control responses linked to progression of airway inflammation, remodeling and hyperresponsiveness in human ASM cells. We used primary cultured ASM cells as well as hTERT-immortalized human ASM cells. With immunoblotting we demonstrate that exogenous
HMGB1 (10 ng/mL) can induce rapid and sustained phosphorylation of p42/p44 mitogen-activated protein kinase (MAPK) that is comparable to that induced by a potent mitogen, platelet derived growth factor (PDGF-BB, 10 ng/mL). We also found that TGF-β
1 (2.5 ng/mL) promotes the accumulation of secreted
HMGB1 in culture medium in a time line concomitant with expression of ECM proteins, collagen and fibronectin, suggesting a role for
HMGB1 in pro-fibrotic effects of TGF-β
1. By lentiviral delivery, we induced stable expression of short hairpin RNA (shRNA) that silenced expression of endogenous
HMGB1 or mammalian diaphanous
1 (mDia1), a cytoplasmic scaffold protein that is required for
HMGB1-induced cell responses through one of its receptors, receptor for advanced glycation end products (RAGE). Immunoblot analyses revealed that silencing of mDia1 was associated with markedly decreased induction of p42/p44 MAPK phosphorylation by exogenous
HMGB1. In
HMGB1-silenced human ASM cells, we observed significantly reduced synthesis and secretion of collagen A1 and fibronectin in response to TGF-β
1 (2.5 ng/mL, 0-48 hrs). However, exogenous
HMGB1 was not sufficient to rescue ECM synthesis in response to TGF-β
1 in
HMGB1-silenced cells - this suggests that intracellular, but not necessarily secreted
HMGB1, regulates ECM expression and secretion in response to TGF-β
1. Consistent with this interpretation, exogenous
HMGB1 alone was not sufficient to induce ECM synthesis or secretion in primary cultured ASM cells. In conclusion, we show that though in human ASM cells extracellular
HMGB1 alone can activate MAPK signaling, likely via mDia1-dependent pathways involving RAGE. it is not capable of prompting ECM protein expression. Recombinanat…

▼ Asthma is a heterogeneous disorder encompassing distinct clinical phenotypes thought to be mediated by distinct mechanisms. The Receptor for Advanced Glycation End products (RAGE) is a pattern-recognition receptor capable of ‘sensing’ exogenous and endogenous molecules; and there is evidence that ligand-RAGE axis is activated in asthma. We investigated the role of RAGE and its ligand high-mobility group box-1 (HMGB1) in the inception and progression of allergen and virus-induced asthma using mouse models. We demonstrate that RAGE is a critical mediator of allergic airway sensitization induced by house dust mite (HDM) and cockroach (CR) allergens. Our studies suggest that RAGE is engaged secondary to the release of HMGB1 by airway epithelial cells; and that HMGB1-RAGE signalling drives type 2 immunity and airway inflammation. RAGE is also required for anti-viral immunity to pneumonia virus of mice (PVM) (equivalent to human respiratory syncytial virus). PVM infection in RAGE-deficient mice led to increased HMGB1 expression in the airways; this contributed to the development of an asthma-like pathology characterised by airway smooth muscle remodelling, airways hyperresponsiveness and the absence of granulocytic inflammation, representing a pauci-granulocytic phenotype of human asthma. In separate studies we investigated whether an anti-IL-6 receptor (IL-6R) antibody protects against allergic airway inflammation. Intriguingly, anti-IL-6R protected against CR-induced airway inflammation but exacerbated the airway inflammatory response to HDM. This differential response was related to differential activation of IL-6 signalling mechanisms in response to CR and HDM. The studies herein expose novel molecular mechanisms that may explain the development of specific phenotypes of human asthma in response to viral or allergic triggers. Selective targeting of these pathways in appropriate patient sub-groups may lead to better outcomes in asthma management.

house dust mite (HDM);

▼ High plasma levels of inflammatory mediator, high mobility group box protein 1 (HMGB1), and its main receptor, receptor for advanced glycation end products (RAGE), is associated with poor prognosis for a variety of cancers, but little is known about this signalling axis in chronic lymphocytic leukaemia (CLL). We have previously determined significantly increased HMGB1 levels in the plasma of CLL patients compared to healthy controls, associated with poor clinical outcome. It is unknown whether the HMGB1-RAGE signalling axis contributes to disease progression and can directly promote CLL B-cell survival by converging with toll-like receptor 9 (TLR9) signalling. Moreover, the role of soluble RAGE (sRAGE), a free extracellular receptor fragment that functions as a decoy receptor in blood plasma, is poorly documented for CLL. The overall aim of my PhD is to (1) determine expression of HMGB1 receptors, RAGE and TLR9, in CLL B-cells and their prognostic significance in patients with CLL; (2) assess global cell-signalling network activation following exogenous HMGB1 treatment and blockade with neutralising anti-RAGE antibody; (3) study the impact of sRAGE in CLL. Lymph node RAGE expression positively correlated with TLR9, Ki67 and ZAP70 - markers of proliferating and aggressive disease. Patients with high lymph node RAGE expression confer inferior overall survival in comparison to patients with low RAGE expression. Further risk stratification of RAGE with Ki67 and ZAP70 lymph node expression increased the prognostic power of RAGE, highlighting a significant interaction between these variables. HMGB1 induced activation and colocalization of RAGE and TLR9 in CLL B-cells. Phosphoproteomic analysis highlights activation of MAPK signalling in primary CLL cells following HMGB1 treatment in vitro for patients with ZAP70 expression. We confirmed increased plasma levels of HMGB1 and surprisingly of sRAGE in CLL patients compared to healthy controls, but not of other RAGE ligand, S100B. Plasma sRAGE levels did not reach a high enough concentration to inflict full HMGB1 inhibition, but RAGE shedding could be induced in vitro by stimulating metalloprotease termed a disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) with ionomycin in RAGE-transfected HEK293 cell line and primary CLL cells, and blocked when ADAM10 was specifically inhibited with GI254023X. In summary, this study demonstrates that overexpression of HMGB1 receptor, RAGE, in CLL lymph nodes is associated with a worse clinical outcome in patients with CLL. HMGB1 activates both RAGE and TLR9 in primary CLL B-cells. sRAGE has a protective effect in CLL by prolonging time to first treatment and sRAGE originates from ectodomain shedding, dependent on ADAM10. We therefore propose that HMGB1 and surface RAGE may play an important role in promoting CLL cell proliferation and cell survival, and plasma sRAGE combined with HMGB1 could be markers of disease monitoring.

▼ Renal transplantation invariably results in tissue injury resulting from ischemia reperfusion injury (IRI), inflammation, drug toxicity, and rejection. Tubular epithelial cells (TEC) comprise the majority of renal parenchyma and are susceptible to cell death and injury during diverse forms of inflammation, which has direct and indirect effects on long term allograft function. Renal TEC have the unique ability to attenuate inflammation and alloimmune injury through the expression of various mediators of cell death and inflammatory molecules. Inhibition of cell death pathways in renal allografts may influence outcomes of alloimmune responses and graft survival. In this body of investigation, alteration of apoptosis and necroptosis forms of TEC death in vitro, were tested for their ability to extend allograft survival in vivo. Apoptotic death induced by cytotoxic cells during allograft rejection was inhibited by TEC expression of Granzyme B inhibiting serine protease inhibitor-6 (SPI-6) and prolonged graft survival and function. Apoptosis death of TEC can also be initiated during renal IRI and with rejection by pro-inflammatory cytokines through surface death receptors. However, inhibition of TNFα-induced apoptosis in TEC through caspase-8 upregulated the receptor interacting protein kinase 1 and 3 (RIPK1/3)-mediated necroptosis pathway to limit graft survival. However, inhibition of RIPK1/3 necroptotic death during renal IRI and transplantation was able to preserve renal function and promote long term graft survival. Augmented pro-inflammatory effects following necrotic cell death were related to an increased release of high mobility group box 1 (HMGB1). Use of the HMGB1 inhibitor glycyrrhizic acid (GZA) inhibited inflammatory responses in vitro and was able to ameliorate renal IRI. Collectively these studies highlight the importance of endogenous donor kidney factors in regulating inflammatory cell death and subsequently the severity and outcomes of allograft rejection. Regulators of parenchymal cell death in kidney and other solid organs may provide entirely new therapeutic targets for transplantation which will promote long term allograft survival.

▼ Neuroinflammation is associated with microglia reactivity in Alzheimer’s disease (AD) in the presence of amyloid-β (Aβ) peptide. Interestingly, expression and activation of the alarmin
high mobility group box 1 (
HMGB1) were recently associated with neuroinflammation in the aged brain and noticed to contribute to AD pathology. Recent results from our
group indicate that Aβ upregulates
HMGB1 mRNA in a culture model of reactive microglial cells.
Here we aimed to assess the effects of modulating
HMGB1 gene expression in young/reactive and aged/irresponsive microglia, when stimulated by Aβ. Therefore, mixed glial cultures were obtained from CD1 mice pups. Microglia were isolated, maintained for 3 (young) or 16 (aged) days in vitro (DIV) and transiently transfected to silence (si) or overexpress (p)
HMGB1, respectively. Cells were then treated (or not) with a mixture of Aβ species (1000 nM). We evaluated: autophagy (LC3II/I and Beclin-
1); phagocytosis (MFG-E8); phenotypic markers of pro-inflammatory (TLR2/TLR4/NF-kB signalling pathway, NLRP3-inflammasome/IL-18 complex, TNF-α, iNOS and MHCII) or anti-inflammatory (IL-10 and Arginase-
1, CX3CR1) stages; inflamma-miRNAs (miR-155, miR-124 and miR-146a); and senescence.
Aβ induced
HMGB1 expression in 3 DIV/young microglia and promoted autophagy, M1 polarization, as well as senescence, while reducing MFG-E8-associated phagocytosis. Efficient siHMGB1 abrogated all these effects, with exception of NLRP3 mRNA upsurge. Contrarily, Aβ couldn’t trigger
HMGB1 upregulation in 16DIV/aged microglia, only achieved in pHMGB1-treated samples. pHMGB1 diminished senescence in Aβ-challenged cells and increased the expression of pro- and anti-inflammatory markers, even in the absence of Aβ challenge.
Overall, our data suggest that siHMGB1 protects young microglia from excessive activation without compromising their responsiveness, while pHMGB1 allows aged microglia to regain a reactive profile. Therefore, selective modulation of
HMGB1 appears essential to preserve microglia’s key functions, supporting a potential therapeutic application in AD with advantages over conventional broad effect anti-inflammatory agents.

▼ Previous studies have shown that inflammation
is a key factor in determining scar formation in cutaneous fetal
wounds. In a fetal mouse model, sterile wounds generated on
embryonic day 15 (E15) have little to no inflammation and heal
scarlessly, while wounds generated on embryonic day 18 (E18) have
inflammation and heal with a scar. The mechanisms leading to
age-related differences in inflammation and healing are not fully
understood. Alarmins, which comprise a
group of
endogenous danger signals, have been implicated in promoting
inflammation in various organ systems and disease processes. This
study evaluates the role of a specific alarmin,
high mobility group
box 1 (HMGB-
1), in cutaneous fetal wound healing. HMGB-
1 is a
non-histone architectural DNA binding protein localized within the
nucleus of the cell. However, it can be released by both passive
and active mechanisms. Passive release into the extracellular
matrix occurs as a result of cell injury or necrosis. While active
secretion is described as a capability of several cell types,
including immune cells. Once in the extracellular space, HMGB-
1
stimulates inflammation by binding to RAGE (receptor for advanced
glycation end products) or toll-like receptors present on
inflammatory cells. This is the first study to
evaluate the role of HMGB-
1 in the process of fetal wound healing.
We hypothesized that alterations in the expression or release of
HMGB-
1 between early and late gestation fetal wounds contribute to
the differences seen in healing outcomes. To begin, comparisons of
HMGB-
1 expression in fetal wounds that heal scarlessly and wounds
that heal by scar formation were made. Later experiments tested the
ability of HMGB-
1 to induce scar formation in E15 wounds that have
previously been shown to heal scarlessly. Finally, mechanisms of
action were explored to decipher how HMGB-
1 affects fibroblasts,
the cells ultimately responsible for scar
formation. Immunohistochemical staining of E15
and E18 skin revealed age-related differences in HMGB-
1 expression
patterns in both unwounded and wounded skin. As compared to E15
basal keratinocytes, basal keratinocytes of E18 skin expressed
higher nuclear HMGB-
1 staining and demonstrated a more substantial
loss of nuclear staining after injury, suggesting that HMGB-
1 is
released to a greater extent in E18 wounds. Furthermore, E15 wounds
treated with HMGB-
1 could be induced to heal by fibrosis with
differences seen in both the amount and quality of collagen present
within the scar. Age-dependent differential
release of HMGB-
1 from fetal keratinocytes during wound healing and
the capability of HMGB-
1 to induce scar formation in E15 wounds
that naturally heal scarlessly were found. These results support
the hypothesis that alterations in expression or release of HMGB-
1
contribute to the difference seen in healing outcome between early
and late fetal wounds. This study suggests both the timing and
degree of extracellular HMGB-
1 release are potential factors in
determining whether scarless or fibrotic…

▼ Interleukin 33 (IL-33) is a nuclear cytokine from the IL-1 family which is constitutively highly expressed in barrier sites, acting via the suppression of tumorigenicity 2 (ST2) receptor. On the other hand, high-mobility group box 1 protein (HMGB1) is a chromosomal multifunctional redox sensitive protein. Many actions of HMGB1 are mediated through the receptor for advanced glycation endproducts (RAGE). Both molecules serve various roles in different cellular compartments. Extracellularly, they act as alarmins with multiple roles in immunity and cell homeostasis. Productions of IL-33, HMGB1 and soluble forms of the receptors (sST2 and sRAGE, respectively) have been implicated in several pulmonary diseases. Both axes have been scarcely investigated in pleural diseases. The aims of this thesis were to determine the levels of IL-33 and sST2 as well as ΗΜGB1 and sRAGE in transudative (TrPEs), malignant (MPEs) and parapneumonic (PPEs) pleural effusions (PEs) and investigate the effect of PE fluids with low and high IL-33 or HMGB1 levels on MeT-5A cell adhesion, migration and sphere formation. Further, recombinant IL-33 and HMGB1 were separately used to assess effects on MeT-5A adhesion, migration and sphere formation. IL-33 and sST2 levels were similar among TrPEs, MPEs and PPEs. However, HMGB1 and sRAGE levels were significantly higher and lower, respectively in exudative pleural effusions compared to TrPEs. HMGB1 and sRAGE levels can effectively discriminate transudates from exudates. Remarkably, HMGB1 and sRAGE levels are differentiated between various PEs in an age-dependent manner. A significant positive correlation was found between IL-33 and LDH in TrPEs and between IL-33 and red blood cells (RBCs) in MPEs, while sST2 correlated with lymphocytes in TrPEs. HMGB1 was positively correlated with RBCs and lymphocytes in MPEs. No correlation was found between sRAGE and cellular or specific biochemical characteristics of PEs. Furthermore, we found that in exudates (MPEs and PPEs) high or low levels of IL-33 had significant differential effects on MeT-5A adhesion and migration, while no effect in both cell 33 phenotypes was determined for TrPEs. Further, based on etiology high or low levels of HMGB1 have differential effects on mesothelial cell adhesion, migration and sphere formation. Moreover, significantly decreased MeT-5A cell migration was found when higher concentrations of recombinant IL-33 were used. 50 ng/mL and 100ng/mL of recombinant HMGB1 significantly decreased cell adhesion and sphere size, respectively. These results highlight the emerging role of the IL-33/ST2 and HMGB1/sRAGE axes in pathophysiology of pleural disease. However, further research to improve our understanding of both signaling pathways in pleural homeostasis and disease will be essential to translate aforementioned findings into clinical practice and be able to predict benefits and risks of evolving therapies.

▼ HMGB proteins are eukaryotic, chromatin-associated proteins that play roles in both DNA dynamics and transcription regulation. Hmo1p is an HMGB protein in Saccharomyces cerevisiae that behaves somewhat like a hybrid between mammalian HMGB proteins and the metazoan linker histone H1. mTORC1, a protein complex containing the Tor1p kinase and a major regulator of cellular growth, is inhibited by both rapamycin and stress. It has also been shown to not only associate with Hmo1p at various gene promoters, but also regulate the HMO1 gene itself through direct binding. In this study, the Hmo1p-mTORC1 relationship was further investigated through two questions: 1) Does the transcription factor Sfp1p play a role in relaying mTORC1’s signal to the HMO1 promoter, and 2) Is the reduction in HMO1 transcripts during stress dependent on mTORC1? Gene expression analyses revealed that Sfp1p is not required for normal HMO1 transcription; however, it does appear to play a role in transmitting the mTORC1 stress signal to the promoter, as transcripts are only significantly decreased during stress when Sfp1p is present. Survival tests revealed that Sfp1p might be hindering the cell’s ability to repair DNA double-strand breaks, as there is a slight increase in cell survival during double-strand break-induction when Sfp1p is knocked-out; however, there is some uncertainty as to whether this is Hmo1p-related. Chromatin Immunoprecipitation techniques were then used to demonstrate that RNA polymerase II is evicted from the HMO1 gene over the course of one hour during stress when Tor1p is knocked-out. This same phenomenon had previously been shown in wild-type cells; however, HMO1 transcripts are only attenuated in wild-type cells, and not when Tor1p is knocked-out. This suggests that mTORC1 is responsible for the reduction of HMO1 mRNA during stress. We propose the possibility that mTORC1 is participating in active mRNA degradation at the HMO1 gene, and that transcription-inhibition techniques can be utilized to confirm this.

▼ Chez les eucaryotes pluricellulaires, la différenciation des cellules repose en partie sur l’activation oula répression des gènes. Les profils d’expression génique mis en place vont perdurer d’une générationcellulaire à l’autre. Ce phénomène met en jeu des mécanismes épigénétiques qui remodèlentlocalement la structure de la chromatine. Chez Drosophila melanogaster, les protéines des groupesPolycomb (PcG) et Trithorax (TrxG) participent au maintien du profil d’expression des gènes au coursdu développement. Les protéines PcG maintiennent les gènes réprimés tandis que les protéines TrxGmaintiennent les gènes activés. Une troisième classe de protéines nommée Enhancers of Trithoraxand Polycomb (ETP) module l’activité des PcG et TrxG. Dorsal Switch Protein 1 (DSP1) est uneprotéine HMGB (High Mobility Group B) classée comme une ETP. Par tamisage moléculaire, nousavions montré que la protéine DSP1 était présente au sein de complexes de poids moléculaire de 100kDa à 1 MDa. Le travail de thèse présenté ici a pour but d’identifier les partenaires de la protéineDSP1 dans l’embryon et de mieux connaître les propriétés biochimiques de DSP1. Premièrement, j’aimis en place puis effectué l’immunopurification des complexes contenant DSP1 dans des extraitsprotéiques embryonnaires. Cette approche nous a permis d’identifier 23 partenaires putatifs de laprotéine DSP1. Parmi ces protéines, nous avons identifié la protéine Rm62 qui est une ARN hélicaseà boîte DEAD. Les relations biologiques entre DSP1 et Rm62 ont été précisées. Deuxièmement, j’aidéterminé, par une approche biochimique, de nouvelles caractéristiques physico-chimiques de laprotéine DSP1.
In multicellular organism, the identity of cell is determined by several factors playing on genesexpression. Once established, the gene expression pattern is transmitted to daughter cells through aprocess involving epigenetic mechanisms that locally reshape the structure of chromatin. In Drosophilamelanogaster, the Polycomb (PcG) and trithorax (trxG) group genes are involved in the maintenanceof gene expression profile during development. Inside multimeric complexes, PcG proteins maintaingenes in repressed state whereas TrxG maintain genes active. A third class of proteins, calledEnhancers of Trithorax and Polycomb, regulate PcG and TrxG activities. Dorsal Switch Protein 1(DSP1) is a High Mobility Group B protein acting as an ETP. But DSP1 has not yet been identified inPcG or TrxG complexes. On the basis of gel filtration analysis of protein complexes in embryo nuclearextracts, it appears that the majority of DSP1 is present in complex(es) from 100 kDa to 1MDa. Aimsof present work are the identification of DSP1 protein partners in drosophila embryo and thecharacterization of biochemical properties of DSP1. Firstly, I used immunopurification from drosophilaembryonic nuclear extracts. The proteins purified with DSP1 were characterized through sequencingof peptides from individual protein bands by mass spectrometry. Among identified proteins, wefocused on the DEAD Box RNA helicase, Rm62. The…

▼ In the present era of combination anti-retroviral therapy (ART), the latent cellular reservoir of HIV is recognized as the major barrier to a cure. HIV latency may be reversed by a controlled induction of virus reactivation in the presence of ART to reveal latently infected cells for immune system recognition and destruction. Histone deacetylase inhibitors (HDACis) have been used as potential latency reversing agents for HIV. Suberoylanilide hydroxamic acid (SAHA), the most widely tested HDACi, has effectively induced expression of HIV RNA in patients on suppressive ART, but has failed to reduce the size of the latent reservoir. The secondary effects of SAHA on host gene and protein expression are among the possible explanations of why SAHA has failed to deplete the latent reservoirs. SAHA upregulates the high mobility group AT-hook 1 (HMGA1) gene, which encodes a protein that represses reporter transcription from HIV promoter, long terminal repeat (LTR) in primary CD4 T cells. In this thesis study, we investigated the role of HMGA1 in HIV reactivation by SAHA. Latently infected CD4 T cells from 11 different blood donors were generated through in vitro model of HIV latency and were each treated with 1uM SAHA or its solvent dimethyl sulfoxide (DMSO). The expression of HMGA1 and HIV reactivation were assessed using droplet digital PCR (ddPCR). The degree of HMGA1 upregulation by SAHA negatively correlated with levels of HIV reactivation. Knockdown experiments were conducted using GapmeR technology in primary CD4 T cells. HMGA1 GampeRs were used to test whether HMGA1 played a role in HIV reactivation by SAHA. Latently infected CD4 T cells from 5 seronegative blood donors were generated through in vitro model of HIV latency and were each treated with 1 uM SAHA or DMSO. The expression of HMGA1 and HIV multiply spliced transcripts was measured using ddPCR. Although, a modest knockdown of HMGA1 was achieved, the improvement of HIV reactivation by SAHA in three samples suggested that HMGA1 presents a potential target for improvement of HIV reactivation by SAHA. However, further studies that optimize HMGA1 knockdown are needed to fully understand the role of HMGA1 in HIV reactivation by SAHA.

▼ La poly(ADP-ribosyl)ation est une modification post-traductionnelle des protéines catalysée par une famille d’enzymes : les poly(ADP-ribose) polymérases. Parmi les plus étudiées, PARP-1 et PARP-2 interviennent dans l’organisation, l’expression et le maintien de l’intégrité du génome. Nous avons initié l'étude d'un nouveau partenaire de PARP-1 préalablement identifié par double-hybride, et encore peu étudié à ce jour : HMG2L1 (High-Mobility Group protein 2 Like-1). La protéine humaine de 601 acides aminés contient un domaine HMG (High-Mobility Group) normalement impliqué dans l’interaction avec l’ADN. Quelques études ont montré que HMG2L1 régule la transcription en agissant comme co-régulateur négatif ou positif. Dans un premier temps, nous avons caractérisé le lien entre PARP-1 et HMG2L1. L’interaction avec PARP-1 a été confirmée in-vivo et in vitro. Nous avons montré que HMG2L1 pouvait également interagir avec PARP-2. HMG2L1 est poly(ADP-ribosyl)ée par PARP-1 et PARP-2, de même qu’elle est capable d’interagir avec le poly(ADP-ribose). La construction de formes tronquées de HMG2L1 en fusion avec la GFP nous a permis de montrer que le domaine N-terminal – en amont du domaine HMG – est impliqué dans ces interactions. Ce domaine N-terminal est très électropositif et intrinsèquement désordonné ce qui lui confère de nombreuses potentialités d’interactions. L’expression des fusions GFP dans des cellules HeLa nous a permis de montrer la localisation nucléaire et nucléolaire de HMG2L1, comme c’est le cas pour PARP-1 et PARP- 2. En outre, HMG2L1 colocalise avec UBF (Upstream Binding Factor), le facteur de transcription de l’ARN polymérase I responsable de la transcription des ARN ribosomaux. La surexpression de GFP-hHMG2L1 entraîne un stress nucléolaire caractérisé par l’inhibition de la transcription des ADNr et la formation de coiffes nucléolaires. Nous avons également entrepris une recherche de partenaires de HMG2L1 par spectrométrie de masse. De nombreuses protéines nucléolaires, impliquées dans la biogenèse des ribosomes ou la maturation des ARNs ont été identifiées, suggérant un rôle de HMG2L1 dans ces processus. Nous avons montré que la protéine purifiée interagit avec l’ADN via son domaine HMG principalement, et qu’elle interagit avec l’ARN via son domaine N-terminal. Mais surtout, nous avons mis en évidence une activité ARN-chaperonne, qui peut être régulée par le poly(ADP-ribose). La localisation de HMG2L1, son réseau d’interaction ainsi que son activité chaperonne nous laissent à penser qu’elle pourrait être impliquée dans des processus de maturation des ARN, régulés par la poly(ADPribosyl)ation.
Poly(ADP-ribosyl)ation is a post-translational modification of proteins mediated by a family of enzymes called poly(ADP-ribose) polymerases. Among the best studied, PARP-1 and PARP-2 are both implicated into the transcription, organization and integrity of genome. We have initiated the characterization of a new PARP-1 partner previously identified in a yeast two-hybrid screen, and still poorly studied: HMG2L1…

▼ In the eukaryotic nucleus, an immense length of DNA is compactly packaged to generate an ordered three-dimensional hierarchical structure called chromatin (van Holde, 1988; Wolffe, A.P, 1998). This organization forms a template for various DNA transaction processes like replication, transcription, recombination etc. The different stages of organization of the chromatin finally results in the 10,000-fold compaction observed in the metaphase chromosome. The problem of how the fibres of chromatin are folded has interested biologists and biochemists for decades. It has long been recognized that the Histones play a major part in this folding. However, the distinctly different roles of the Histones H2A, H2B, H3 and H4 on one hand and the lysine rich Histones such as Histone H1 and its cognates on the other, were not understood until after the discovery of the nucleosomes in the early 1970s. Some of the early insights into the structure of chromatin came through the digestion of nuclear chromatin with calcium-dependent endonucleases like micrococcal nuclease. A repeating kinetic intermediate of about 200 bp of DNA with Histones was obtained (Simpson, 1978). Based on repeating pattern of micrococcal nuclease digested chromatin and structural studies, Kornberg (1974) proposed that chromatin is composed of a flexible chain of repeating units of 100 A0 diameter. These units were termed as "nucleosomes" (Oudet et al, 1975). It then became clear that the Histones H2A, H2B, H3 and H4 were constituents of the nucleosome core particle whereas the lysine rich Histone H1 was somehow associated with the linker DNA between core particles. Hence, the formers are called core Histones and the latter as linker Histones. On further digestion of nucleosome, a nucleosome core was obtained in which wrapping of 146 bp of DNA about the Histone octamer to form the core particle provided the first level of folding. Electron microscopy and X-ray diffraction techniques suggested that this particle is a disk, 57 A0 thick and 110 A0 in diameter, and that the DNA is wound around the Histone core (Finch et al, 1977), But this cannot account for the many thousand-fold condensation of the DNA in the eukaryotic nucleus. The "string of beads" structure observed obviously could not satisfy the compaction requirement. It soon became evident that there exists some level of higher order folding of the chromatin fiber. In a classical paper, Finch and Klug (1976), showed that the extended nucleosomal filaments condense into irregular fibers of about 30 nm diameter in the presence of low concentrations of Mg 2+. Based on the data from earlier structural studies, these authors proposed a solenoid model in which nucleosomes were wrapped into a regular helix with a pitch of about 11nm. Later, it was observed that the formation of well defined fibers requires the presence of lysine rich Histones such as Histone H1.

▼ The DNA of eukaryotic cells does not exist in free linear strands; it is tightly packaged and wrapped around nuclear proteins in order to be accommodated it inside the nucleus. The basal repeating unit of chromatin, termed the nucleosome, provides the first level of compaction of DNA into the nucleus. Nucleosomes are interconnected by linker DNA and associated linker histones to form 30 nm fibers. The highly diverse linker histones are critical for compaction and stabilization of higher order chromatin structure by binding DNA entering and exiting the nucleosome. The lysine-rich C-terminal domain (CTD) of metazoan H1 is crucial for such stabilization. This study concerns the functions of Saccharomyces cerevisiae Hmo1p, an high mobility group (HMGB) family protein unique in containing a terminal lysine-rich domain and functions in stabilizing genomic DNA.
My study suggests that Hmo1p shares with mammalian linker histone H1 the ability to stabilize chromatin, as evidenced by the absence of Hmo1p or deletion of the Hmo1p CTD creating a more dynamic chromatin environment that is more sensitive to nuclease digestion and in which chromatin remodeling events associated with DNA double strand break repair occur faster; such chromatin stabilization requires the lysine-rich extension of Hmo1p. Further, my data indicates that Hmo1p functions in the DNA damage response by directing lesions towards the error-free pathway. My results suggest that Hmo1p controls DNA end resection and favors the classical non- homologous end joining (NHEJ) over alternate end Joining (A-EJ) that is error-prone process. In all, my study identifies a novel linker histone function of Hmo1p in Saccharomyces cerevisiae with the ability to stabilize genomic DNA, and appears to go beyond conventional linker histone function.

▼ DNA damage is a common hazard that all cells have to combat. Saccharomyces cerevisiae HMO2 is a high mobility group protein (HMGB) that is a component of the chromatin remodeling complex INO80, which is involved in double strand break repair. I show here using DNA end-joining and exonuclease protection assays that HMO2 binds preferentially to DNA ends. While HMO2 binds DNA with both blunt and cohesive ends, the sequence of a single stranded overhang significantly affects binding, supporting the conclusion that HMO2 recognizes features at DNA ends. Analysis of the effect of duplex length on the ability of HMO2 to protect DNA from exonucleolytic cleavage suggests that more than one HMO2 must assemble at each DNA end. HMO2 binds supercoiled DNA with higher affinity than linear DNA and has a preference for DNA with lesions such as pairs of tandem mismatches; however, comparison of DNA constructs of increasing length suggests that HMO2 may not bind stably as a monomer to distorted DNA. The remarkable ability of HMO2 to protect DNA from exonucleolytic cleavage, combined with reports that HMO2 arrives early at DNA double strand breaks, suggests that HMO2 may play a role in double strand break repair beyond INO80 recruitment. I also found that HMO2 has the ability to mediate both 3Œ and 5Œ DNA strand invasion, which is an essential step in homologous recombination. Also hmo2∆ and hmo2∆rad52∆ have slower growth phenotype in presence of hydroxyurea thus indicating that HMO2 might play important role in recovery of stalled DNA replication forks.

▼ La neuro-inflammation induite par l'inflammation systémique ou générée en réponse à une lésion cérébrale aiguë a des conséquences cliniques néfastes : elle est mise en cause dans l'aggravation des lésions cérébrales aiguës chez l'homme, aussi bien chez l'adulte que chez l'enfant. La microglie est l'effecteur cérébral principal de cette réponse inflammatoire, et peut présenter selon les situations un profil neurotoxique ou, au contraire, anti-inflammatoire et régulateur. La compréhension des mécanismes d'activation microgliale et de leurs conséquences est capitale pour une meilleure prise en charge des malades. La première partie de ce travail de thèse s'intéresse aux conséquences de l'inflammation néonatale associée à la prématurité sur la réponse microgliale à l'âge adulte, face à de nouvelles agressions cérébrales que sont l'inflammation systémique et les lésions cérébrales aiguës. Dans un modèle murin d'inflammation néonatale, nous avons mis en évidence d'importantes modifications du transcriptome microglial une fois ces souris adultes. De plus, un stimulus inflammatoire à l'âge adulte modifie le profil d'activation microgliale, le pic des marqueurs pro-inflammatoires et immuno-régulateurs survenant plus précocement et intensément, démontrant l'existence d'une mémoire du système immunitaire inné cérébral. Ces modifications dans le profil d'activation microgliale s'accompagnent dans un modèle de lésion cérébrale excitotoxique d'une majoration de la taille des lésions de la substance blanche. Un traitement par mélatonine des souriceaux prévient cette aggravation. La deuxième partie de ce travail a consisté à caractériser in vitro le profil d'activation microgliale en réponse à une stimulation par HMGB1, une alarmine relarguée lors de la mort cellulaire et donc présente en cas de lésion cérébrale aiguë mais aussi de lésions extra-crâniennes associées. Nous avons montré que le profil d'activation microgliale dépend du type d'HMGB1 utilisé. Les microglies exposées à la forme recombinante de chez Sigma présentent un profil transcriptomique proinflammatoire mais une baisse des taux de cytokines sécrétées dans le milieu. Ces résultats mettent en évidence l'importance de l'inflammation et de l'activation microgliale dans le pronostic des lésions cérébrales et offrent la possibilité de mettre en place des stratégies neuroprotectrices innovantes
Neuroinflammation induced by systemic inflammation or generated in response to acute brain injury has adverse clinical consequences: it is implicated in exacerbation of acute brain injury in humans, for adults as well as for children. Microglia is the main effector of this cerebral inflammatory response, and may present, depending on the situation, a neurotoxic or - on the opposite - anti-inflammatory and regulating profile. To decipher the mechanisms of microglial activation and their consequences is essential for better management of patients.The first part of this thesis focuses on the consequences of neonatal inflammation associated with prematurity on the microglial response…

▼ In the foreseeable future, the elderly will make up a significant proportion of New Zealand’s population. The relationship between ageing and disability means the disabled population is expected to increase as the population ages. Physical disabilities especially
mobility impairments have adverse impacts on the life experience of elderly people. The outdoor environment contributes to the physical and mental health of ageing people and can provide the opportunities to enhance their quality of life. This thesis explores the concept of a rehabilitative landscape design at Kenepuru Community Hospital. The design aims to improve and maintain
mobility during the ageing process, and potentially provide feedback which will motivate the ageing to continue a healthy lifestyle. The thesis concludes that the “disabled” elderly and their community gain a better life experience while reconnecting with a strategically designed outdoor environment.

▼ The selective activation of genes is essential for diverse biological processes such as growth, development, and responses to environmental cues. Unlike lower organisms that often use individual proteins to control gene activation, transcription regulation in higher organisms generally requires cooperation among multiple proteins. Cooperation can be achieved via interactions between DNA-binding proteins that bind to adjoining DNA sequences. Such interactions can stabilize DNA binding by these proteins. Many eukaryotic transcription factors form heterodimers that can bind to DNA in two opposite orientations. Because of the asymmetry of such heterodimers, cooperative DNA binding has been predicted, and in some cases observed, to require a specific orientation of heterodimer binding.
Interferon regulatory factor 3 (IRF3) and a heterodimer containing activating transcription factor 2 and c-Jun (ATF2-Jun) bind cooperatively to the human interferon-beta enhancer, and opposite orientations of ATF2-Jun binding have been observed using different experimental approaches.
High mobility group protein I (HMGI) binds to sequences overlapping the ATF2-Jun-IRF3 site within the interferon-beta enhancer and facilitates DNA-binding and synergistic transcriptional activation by components of the enhancer complex, yet its effects on ATF2-Jun-IRF3 complex formation have not been investigated. This thesis presents the identification of the structural determinants of ATF2-Jun heterodimer orientation at the interferon-beta enhancer in vitro as well as functional characterization in cells. Using gel-based fluorescence resonance energy transfer analysis, I found that ATF2-Jun binds to the interferon-beta enhancer in both orientations alone and in association with IRF3 and HMGI. Two symmetry-related sets of amino acid residues in ATF2 and Jun facilitated the opposite orientations of heterodimer interactions with IRF3 at the interferon-beta enhancer. Expression of ATF2 and Jun variants that bound the interferon-beta enhancer in opposite orientations together with IRF3 produced distinct levels of interferon-beta transcription in Sendai-virus infected Hela cells. Expression of these proteins resulted in different relative levels of transcription of different genes regulated by ATF2 and Jun. Collectively, this work illustrates a novel mode of cooperative DNA-binding by transcription factors and suggests that alternative nucleoprotein arrangements can influence transcriptional activity through distinct mechanisms at different genes.

▼ The first section of this dissertation describes the
development of strategies for the treatment of pancreatic cancer
using a novel synthetic DNA sequence that functions as decoy
binding site for an oncogenic protein called
high mobility group A
(HMGA) and adenovirus mediated gene therapy. The second part of
this dissertation describes a survey study for evaluating the
antibacterial activity of mushroom samples collected from local
areas. The Chapter
1 provides background information about the HMGA
and its role in tumor development and cancer progression. The
Chapter
1 also provides background information about the adenovirus
and its use in cancer treatment. In addition, Chapter
1 discusses
about the medicinal use and antibacterial potential of mushrooms.
In Chapter 2, we have devised a strategy of using engineered
replication-defective adenovirus (Ad) to deliver decoy hyper
binding sites for HMGA to the nucleus of cancer cells with the goal
of sequestering excess HMGA at the decoy hyper binding sites due to
binding competition. Sequestration of excess HMGA at the decoy
binding sites is intended to reduce HMGA binding at the naturally
occurring genomic HMGA binding sites, which should result in
normalized gene expression and restored sensitivity to
chemotherapy. Infection of five different pancreatic and liver
cancer cell lines with the Ad containing the HMGA decoy hyper
binding sites resulted in significant reduction in cell viability
and increased sensitivity to chemotherapy. The Chapter 3 discusses
toxicity and biodistribution following injection of the Ad
containing the HMGA decoy hyper binding sites into mice liver or
pancreas. This study provides essential preclinical information
regarding toxicity and biodistribution needed to determine the
potential of our engineered virus for future treatment of cancer in
humans. The Cahpter 4 demonstrated a strategy to develop a
conditionally replicating Ad virus which will selectively replicate
in cancer cells while being unable to replicate in normal cells. We
have shown that the deletion of two genes, E1ACR2 and E1B19K,
increased cancer selective replication of the Ad and decrease
chemotherapy resistance of pancreatic cacner cells. In Chapter 5,
we have described a survey study where we showed antibacterial
activity in 25 mushroom samples out of the 75 samples tested.
Finally the Chapter 6 summarizes the present research and shows
future direction.

▼ Pancreatic cancer is the third leading cause of cancer
related deaths. Individuals inflicted with this cancer are
typically asymptomatic until advanced stages are reached. Surgical
procedures provide the greatest chance of survival; nevertheless,
pancreatic cancer is rarely detected in early stages where surgery
would be effective. This is primarily due to the lack of dependable
tests for early detection and diagnosis. Current diagnostic methods
are extremely invasive or are deemed inadequate by general
consensus, and population screening for pancreatic cancer with
these methods is not feasible. Urine and fecal excrements have been
shown to encompass potentially useful biomarkers in pancreatic
cancer. In this dissertation, potential early biomarkers in serum,
urine, and blood were identified through the use of the mouse model
Ptf1aCre; LSL-KrasG12D of pancreatic cancer and nuclear magnetic
resonance spectroscopy (NMR). Additionally, a histology atlas of
pancreatic tissue was produced to aid in the evaluation of the
precancerous stages, referred to as pancreatic intraepithelial
neoplasia (PanIN). Due to the existence of multiple classification
systems being in use, discrepancies among the field exist. The
generated atlas will promote discussion and clarification of the
PanIN stages. In order to acquire images, removal of the pancreas
had to be performed. Due to the lack of peer-reviewed and
high
quality videos and instructions available, a manuscript accompanied
by a video were produced to show the proper procedures to
successfully remove the pancreas by dissection from a mouse. Also,
high-
mobility growth A1 protein (HMGA1), that has been linked to
tumor progression in many cancers, had not been examined with the
Ptf1aCre; LSL-KrasG12D mouse model until now. Elevated levels of
HMGA1 have been shown to be present in as young as 5-months in the
PanIN mice and in as old as 15-months when compared to normal
un-transitioned pancreatic tissue. This dissertation encompasses
many tools, platforms, and analyses assisting in the progression of
early diagnostic pancreatic cancer research.

▼ black
box [
1] is an approximately seven-minute,
single-movement work for full orchestra. This piece is not
programmatic; rather, the piece’s structure is determined by its
content.black
box [
1] is cast in two large sections. In the first
section, instruments are separated into three broad registral areas
(
high, mid, and low). Each
group plays a discrete thematic idea.
The piece begins with each theme stated in turn and they develop as
the section progresses. As the themes develop, they begin
interrupting one another. These interruptions become more frequent
as the section progresses, and at the section’s climax, all three
themes play simultaneously.A percussion solo immediately follows
the climax and leads to the piece’s second section. Similar to the
first section, the second section features three different melodic
ideas. After these are introduced, they develop into three
different phrases using pitches from each theme put into randomized
orders. Each phrase differs in length so that they do not coincide
with each other in the same way for each iteration. These phrases
repeat until the piece’s end.The piece’s first section is cast in
Lydian mode and the harmony modulates twice. The piece’s second
section is cast in a minor key. Each melodic theme in the second
section utilizes a different subset from a minor scale and the key
also modulates two times in this section. The final part of the
second section (with repeated phrases) sounds pandiatonic because
the limited pitch material and the randomized combination of
pitches do not create a sense of hierarchy or utilize functional
harmony.Rhythm plays an important role in black
box [
1]. The piece
is mostly notated in common time so it can be easily read, with
other meters used occasionally in order to begin new phrases on a
downbeat. The first section has an upbeat tempo and features
frequent rhythmic syncopation. The second section unfolds at a
slower tempo (a 33.3% decrease from the first section). This
section feels much more rhythmically “floating” than the preceding
section.

▼ En kulturskola är inte ett skyltfönster för barnens talang utan en kreativ verkstad för att utvecklas. Detta har jag tagit fasta på och har en idé om en kulturskola där större delen av skolan är vikt till barnens trygghet. De vuxna har sin plats och resten av byggnaden är barnens. Här ska blyga kunna öva i trygghet och de som vill spela ut hela sin repertoar har möjlighet till det. Skolan ska också kunna vara en plats att hänga på någon timme innan sin lektion. Gestaltningsmässigt har skolan här ett öppet foajéplan som är semioffentlig. Caféet är öppet för allmänheten och kan användas för utställningar, föreläsningar och liknande. Men denna yta är också den som är de vuxnas. Kommer du med ditt barn så är det här du får vänta medan barnet springer in och gör sitt. Resten av foajéplanet är en flexibel yta som egentligen kan programmeras lite hur som helst. Uppåt i huset finns en yta för barn, som ett väntrum, där de kan hänga innan sin lektion. Uppåt finns också lektionssalar. Blandad verksamhet för att blanda barnen. Den nedre delen av huset är nästan som ett helt annat hus. Här finns verksamhetslokaler samt flertalet av de servicefunktioner som måste finnas. Ytan att vistas på är här begränsad då det inte är tänkt att man ska uppehålla sig här mellan lektionerna. Som en bärande idé har jag fört med mig forskning som visar på hur man kan bygga bort mobbning. Huset har inga långa dolda korridorer och överallt kan lärare överse, utan att bevaka, alla utrymmen där barnen befinner sig. Med hörsel och syn kopplas hela huset samman genom principen att visuell och audiell kommunikation är trygghetens kärna.
A Culture school should not be a kids talent show room. It should be a creative shop for their own development. This is the starting point of my project. I have an idea of a culture school where the bigger part is for the children and only the children. A place to be safe. The shy kids should be able to practice in a safe environment and the more outspoken kids will have the opportunity to perform. This, normally a place you just spend a lesson at, should be a place to hang around after school. The entrance floor is a semi public floor with an café open for the public and with an area to have flexible purposes, maybe a show room one day and an open lecture the next. This area is the only area for the grown ups. When you pass through into the building you are in the world for the kids. The flexible entrance floor is accompanied with a ”half floor” entirely voided for the kids to hang at. Another floor up and two floors down you’ll find the rooms for different activities. The entire house is devoted to minimize bullying. No long corridors, a constant ability for teachers to watch the kids without being monitors and throughout the house you can hear, and almost see, everything.

▼ The quality of GaN template layer plays a very important role in
high electron
mobility transistors. We proposed a special method in the growth of molecular beam epitaxy to deal with the dilemma between structure and the morphology of GaN. In our study, we used a nitrogen-rich GaN growth condition to deposit the initial varied layer. After that, we changed the N/Ga ratio stepwise to the growth condition of gallium-rich GaN and grew the epitaxy layer right away. In X-ray diffraction analysis, the full width at half-maximum (FWHM) value of rocking curves of GaN(002) was improved relatively to gallium-rich sample from 531.69 arcsecond to 59.43 arcsecond. In atomic force microscopy (AFM) analysis, the root mean square (rms) roughness of sample surface was improved relatively to nitrogen-rich sample from 18.28 nm to
1.62 nm over 5 μm à 5 μm area. The Raman scattering shows there is a slightly tilted plane in gradient layer and the gradient layer can also slash the strain force which is caused from Ga-rich GaN epitaxy layer and AlN buffer layer.
A series
high mobility AlxGa1-xN/GaN heterostructures samples were grown on MOVPE-grown GaN templates substrate by molecular beam epitaxy with different Al concentrations (x = 0.017~0.355). The quality checked by XRD and AFM indicated that the excellent properties agreed with the GaN-template. The highest
mobility in this series samples at 8 K is 19593 cm2/Vs with carrier concentration 3.13 Ã 1012 cm-2 and Al concentration x = 0.017. In our experiments, the carrier density decreases as Al concentration reduces. In the illuminated Hall measurement, there are only few electrons increased following blue LED illumination. It shows that there are only few deep level defects existing near the heterointerface. From temperature-depended Shubnikov-de Haas (SdH) oscillations, the electron effective mass m* in 2DEG are evaluated as 0.213 mo and for x = 0.207 0.227 moand 0.136 respectively.
The
high mobility AlxGa1-xN/GaN was fabricated to a series of wires by focused ion beam (FIB) equipment, and the width of the active channel is ranged from 900 nm to 50 nm (900 nm, 500 nm, 300 nm, 200 nm, 100 nm, 80 nm and 50 nm) with the channel orientation in [11 0] direction. The largest spin-splitting energy in the series of wires is 2.14 meV. Due to larger spin-splitting energy and quasi-ballistic transportation, the 200 nm wire is the best candidate to be the channel of the quantum-ring interferometer in our case.

▼ Compared to classical lab instrumentation, the biosensors are being increasingly exploited as promising diagnostic devices for their advantages, such as label-free, ultrasensitive, highly selective,
high accuracy, fast and real-time detection. Fabricating biosensor chip has great benefits for gene-detection, protein-detection, medical diagnosis and development new medicine. The goal of this research work is to develop nitrideâbased
high electron
mobility transistor (N-HEMT) biosensor for the detection pancreatic cancer marker carbohydrate 19-9 (CA19-9) antigen for early detection of pancreatic cancer.
ããN-HEMT biosensor was fabricated through microelectronic semiconductor process technology by growing AlGaN/GaN film using molecular beam epitaxy (MBE). The surface of N-HEMT biosensor was functionalized with modify pancreatic cancer marker CA 19-9 antibody for the detection of pancreatic cancer marker CA19-9 antigen molecule. The proposed research was focused on two important objectives. At first, N- N-HEMT biosensor was subjected to rapid thermal annealing (RTA) temperatures to optimize the device performance by enhancing metal ohmic contact. Secondly, the aluminum content N-HEMT biosensor was changed to investigate the effect on the performance of the device during biosensing.
ããIt was observed that The RTA at 700â resulting in better performance which is evident from the Isd-Vsd measurement and during detection of CA19-9 antigen detection with a minimum concentration of 150 U/mL. When the influence aluminum content of was investigated, it was observed that N-HEMT biosensor with 29% aluminum content has shown a better performance compared with N-HEMT biosensor with 49% aluminum content during CA19-9 antigen detection with a minimum concentration 150 U/mL.
ããFinally, N-HEMT biosensor was successfully fabricated and implemented for early pancreatic cancer detection, which provided important information for the future development of
high sensitivity N-HEMT biosensor for a variety of biological sensing experiments.

▼ A model that can be used to analyze both current and future
high-speed rail corridors is presented in this work. This model has been integrated into the Transportation Systems Analysis Model (TSAM). The TSAM is a model used to predict travel demand between any two locations in the United States, at the county level. The purpose of this work is to develop tools that will create the necessary input data for TSAM, and to update the model to incorporate passenger rail as a viable mode of transportation. This work develops a train dynamics model that can be used to calculate the travel time and energy consumption of multiple
high-speed train types while traveling between stations. The work also explores multiple options to determine the best method of improving the calibration and implementation of the model in TSAM. For the mode choice model, a standard C logit model is used to calibrate the mode choice model. The utility equation for the logit model uses the decision variables of travel time and travel cost for each mode. A modified utility equation is explored; the travel time is broken into an in-vehicle and out-of-vehicle time in an attempt to improve the model, however the test determines that there is no benefit to the modification. In addition to the C-logit model, a
Box-Cox transformation is applied to both variables in the utility equation. This transformation removes some of the linear assumptions of the logit model and thus improves the performance of the model. The calibration results are implemented in TSAM, where both existing and projected
high-speed train corridors are modeled. The projected corridors use the planned alignment for modeling. The TSAM model is executed for the cases of existing train network and projected corridors. The model results show the sensitivity of travel demand by modeling the future corridors with varying travel speeds and travel costs. The TSAM model shows the mode shift that occurs because of the introduction of
high-speed rail.

▼ L'ARN génomique du Virus de l'Immunodéficience Humaine-
1 (VIH-
1) est multifonctionnel. Il constitue le génome encapsidé dans les virions et sert d'ARN messager pour la traduction des protéines virales Gag et Gag-Pol. La traduction de ces protéines dépend exclusivement de la machinerie traductionnelle cellulaire et est initiée par deux mécanismes différents : l'initiation canonique dépendante de la coiffe et l'initiation par entrée interne des ribosomes (IRES). Le VIH-
1 présente deux IRES, l'un dans la région 5' non traduite (5'-UTR) qui est stimulé en phase G2/M du cycle cellulaire et l'autre dans la région codante de Gag. Ce dernier permet l'initiation de la traduction sur deux AUG en phase et conduit à la production de la protéine Gag pleine longueur mais également à la production d'une isoforme alternative de Gag, tronquée en région N-terminale. Le rôle de cette isoforme reste mal connu. Toutefois la mutation du second AUG chez VIH-
1 et donc la suppression de la seconde isoforme de Gag provoque une diminution importante du taux de la réplication virale. La conservation structurelle et fonctionnelle de l'IRES Gag parmi les lentivirus suggère un rôle important de cette isoforme et de l'IRES gag dans le cycle viral. Nos travaux visent à comprendre à un niveau moléculaire les relations hôtes-pathogènes lors de la traduction des messagers viraux. Je me suis particulièrement intéressée aux rôles de la sous unité ribosomale 40S et de l'hélicase cellulaire DDX3 dans l'initiation de la traduction de la polyprotéine Gag du VIH-
1. La première partie de ma thèse est consacrée à l'étude de l'interaction entre la sous unité ribosomale 40S et l'IRES gag du VIH-
1. Par l'utilisation d'approches complémentaires, nous avons pu démontrer la présence de deux sites distincts de liaison au ribosome qui sont présents à proximité des deux codons d'initiation. Nous avons ensuite évalué à la fois in vitro et in cellulo (en collaboration avec l'équipe de T. Ohlmann, CIRI-ENS-Lyon) l'effet de la délétion de chacun des sites de liaison au 40S sur l'efficacité de traduction de la polyprotéine Gag. Nos résultats valident l'importance fonctionnelle des sites de liaison au ribosome pour une production optimale des deux isoformes de la polyprotéine Gag. La seconde partie de mon travail a consisté à définir le rôle de DDX3 dans l'initiation « coiffe-dépendante » de la traduction de la polyprotéine Gag. DDX3 est une hélicase à ARN à boîte DEAD impliquée dans de nombreux processus cellulaires tels que la régulation du cycle cellulaire et la réponse immunitaire innée mais également dans tous les aspects du métabolisme de l'ARN comme la transcription, l'épissage, l'export nucléaire ou encore la traduction. Plus récemment, il a été montré que DDX3 est nécessaire à la traduction de l'ARN génomique du VIH-
1, cependant son rôle exact n'a pas encore été défini. Nous avons purifié une forme recombinante de la protéine en fusion avec la MBP (Maltose Binding Protein) et effectué des cinétiques enzymatiques afin de caractériser ses propriétés biochimiques.…

▼ Mammalian EGR-family genes and T-
box family genes are broadly expressed and mutants result in a variety of defects and diseases (O'Donovan et al., 1999). To aid in our understanding of how these transcription factor families regulate gene expression we analyzed the function of C. elegans egrh-
1 and tbx-2 in the somatic gonad and pharynx respectively.
We found that the C. elegans Early Growth Response factor family member egrh-
1 inhibits oocyte maturation and ovulation until sperm are available. C. elegans is an important system for addressing the fundamental events of oocyte meiotic maturation, ovulation and fertilization, complementing studies in vertebrate systems (Hubbard and Greenstein, 2000). In C. elegans oocyte production, maturation and ovulation must be coordinated with sperm availability for successful fertilization. egrh-
1 mutants exhibit ectopic oocyte differentiation in the distal gonadal arm and accumulate abnormal and degraded oocytes proximally. These defects result in reduced brood size and partially penetrant embryonic lethality. Results of tissue-specific egrh-
1(RNAi) experiments and genetic mosaic analyses revealed EGRH-
1 function is necessary in the soma, and surprisingly this function is required in both the gut and the somatic gonad. Through transformation rescue experiments we show EGRH-
1 in the somatic gonad inhibits oocyte maturation, ovulation and sperm recruitment.
The T-
box family member TBX-2 is the sole C. elegans member of the conserved Tbx2 sub-family. It has been previously shown that C. elegans TBX-2 is required for the development of ABa-derived pharyngeal muscles; however it is not known how TBX-2 specifically regulates the development of these cells. We are interested in identifying TBX-2 targets that function in
pharyngeal muscle development, and in determining if TBX-2 is a transcriptional activator or repressor. To identify targets of TBX-2, we have compared mRNA expression levels in wild-type and tbx-2(bx59) mutant embryos using Affymetrix microarrays. Of 19,885 probe sets examined, we found 980 mRNAs that were significantly up-regulated in tbx-2(bx59) relative to wild-type and 175 mRNAs that were significantly down-regulated. Using clustering analysis, comparisons to existing data sets on pharyngeal gene expression, and phylogenetic foot-printing to identify promoters with consensus T-
box factor binding sites, we have analyzed a subset of genes and identified D2096.6 as a direct target of TBX-2. Our data indicate that D2096.6 is directly repressed by TBX-2 at a variant T-
box binding site in the D2096.6 promoter.

▼ We studied nonlinear electrical transport in high-mobility 2D electron gas (2DEG) forming in modulation-doped GaAs/AlGaAs quantum wells. Transport nonlinearities induced by a pure dc electric field as well as by coexisting dc and microwave fields were studied at very high Landau level filling factors. It was observed that a pure dc electric field could induce transport nonlinearities phenomenologically similar to those previously discovered in microwave-irradiated 2DEG. New phenomena in magnetotransport emerged when a 2DEG was under the simultaneous influences of a dc electric field and a microwave field. The experimental observations were compared to the numerical simulations which were carried out based on a recently proposed theory. Generally speaking, good agreement between the experimental data and the numerical results was obtained. This suggested that the rich transport nonlinearities we have observed so far could all be coherently understood within this theoretical work.
