▼ Current therapy approaches for tyrosine kinase driven
leukemia including Ph⁺ ALL and CML are almost entirely focused on
the development of more potent tyrosine kinase inhibitors (TKI).
The ultimate goal in this approach is to reduce the oncogenic
signaling below a minimum threshold that is required for the
survival of
leukemia cells. Despite the successful results obtained
so far, this approach has its own drawbacks. Unfortunately, TKI
treatment is not very effective in Ph⁺ ALL patients. Furthermore,
in CML patients it can lead to the appearance of resistant tumors
that are not sensitive to therapy anymore. Therefore, new
strategies for killing the Ph⁺
leukemia independent of kinase
inhibition are necessary. ❧ Hypersignaling has been known as an
unfavorable condition for the survival of cells, and induction of
hypersignaling may result in stalled proliferation or cellular
senescence. However, its implication as a therapeutic mean has not
been well-characterized. One strategy for induction of
hypersignaling is to suppress the inhibitory regulators of
signaling pathways. Therefore, we hypothesized that inhibition of
negative feedback regulators or inhibitory phosphatases in Ph⁺
kinase
leukemia could raise the signaling level and induce cell
cycle arrest or senescence in transformed cells. Importantly, cells
lacking high oncogenic kinase activity should be insensitive to
such inhibition of negative feedback signaling. ❧ In chapter two of
this thesis, we focused on the mitogen-activated protein kinase
(MAPK) pathway. By the analysis of gene expression changes and
evaluation of protein levels, we found that DUSP6 and SPRY2, two
negative feedback regulators of the MAPK pathway, are highly
expressed in human B cell lineage Ph⁺ ALL, while they are not
expressed in B cell progenitor cells. Interestingly, in contrast to
BCR-ABL1 kinase driven
leukemia, non kinase-driven B cell
Non-Hodgkin-Lymphoma (B-NHL) lack expression of these genes. To
study the function of DUSP6 and SPRY2 in a genetic mouse model of
Ph⁺ like
leukemia, we transduced bone marrow pre-B cells from
DUSP6-/-, SPRY2fl/fl mice and respective wildtype controls with
retroviral BCR-ABL1. Defects in either of these two negative
feedback mediators caused profound signaling imbalances in BCR-ABL1
leukemia cells and resulted in drastic negative consequences for
the cells. For instance, Dusp6-deficient
leukemia cells rapidly
underwent cellular senescence and were less capable of colony
formation in semisolid culture. In addition, Lack of Dusp6 and
Spry2 dramatically increased cellular reactive oxygen species
(ROS). Furthermore, inducible Cre-mediated deletion of Spry2 in
leukemia cells resulted in rapid cell death. ❧ To test whether
negative feedback signaling molecules represent a potential target
for pharmacological inhibition in the treatment of kinase driven
leukemia, we tested the DUSP6 small molecule inhibitor
2-benzylidene-3-(cyclohexylamino)-1-Indanone hydrochloride (BCI).
BCI induced massive accumulation of ROS and subsequent cell death

▼ Intensification of treatment for
Acute Lymphoblastic
Leukemia (ALL) has improved survival but has also led to large
increases in treatment-related toxicity (TRT). Weight and body
composition are well-recognized mediators of chronic disease whose
impact in childhood cancer is still being determined. Previous
studies and pilot data have demonstrated that children with ALL
undergo significant changes in body composition during therapy that
may have a significant effect on TRT and outcome. ❧ We therefore
undertook a two-part investigation into body composition and its
effect on TRT in childhood ALL. Children's Oncology Group (COG)
CCG-1961 was a large cooperative group clinical trial in high-risk
ALL. We conducted a secondary analysis of the study that
demonstrated either weight extreme, severely underweight or obese,
was associated with increased TRT. Outcome as measured by
event-free survival (EFS) was worse in both weight extremes but
this did not reach statistical significance on multivariate
analysis. The second half of our investigation is ongoing and
explores a common complication of ALL therapy. Poor bone health
affects approximately one in four children during treatment and
also has the potential for long-term sequalae and reduced quality
of survival. As Vitamin D insufficiency is prevalent in this
population and known to be a key mediator of bone health, we
therefore designed a prospective, randomized, double-blinded,
placebo-controlled interventional clinical trial of Vitamin D
supplementation in the context of body composition. This will also
provide an in-depth description of bone metabolism during treatment
for ALL that will help identify other targets for future
intervention. ❧ These two studies represent only the surface of the
likely impact of weight and body composition on TRT in the
treatment of childhood ALL and other cancers and further research
is required to continue to characterize their effect on different
morbidities.

▼ Acute lymphoblastic leukemia (ALL) affects
individuals at all ages, with peak incidences in children <4
years and adults >50 years. ALL is broadly categorized into
B-cell precursor (BCP) and T-cell ALL with specific clinical
features associated with outcome. In contrast to pediatric ALL,
which has a favorable prognosis, adult ALL is associated with a
much poorer outcome with less than 40% overall survival rates,
decreasing with higher age. The presence of specific acquired
genetic abnormalities is important for diagnosis, prognostication,
and treatment stratification. ALL can be further categorized into
subgroups defined by structural or ploidy abnormalities. One such
subgroup, hypodiploid ALL (<46 chromosomes) is seen in 5-8% of
all cases, and associated with a very dismal prognosis. It can be
further subdivided into two distinct genetic and clinical
subgroups, namely near-haploidy (24-31 chromosomes) and low
hypodiploidy (32-39 chromosomes), and, comprising cases with a more
heterogenous background, high hypodiploidy (40-43 chromosomes) and
cases with 44 and 45 chromosomes. Near-haploid and low hypodiploid
ALL are very rare, comprising less than 1% of BCP ALL, with overall
survival rates of <30%. The general aim of my PhD project has
been to characterize ALL patients with a poor prognosis, including
adult ALL (article I) and hypodiploid ALL (article II-IV). To
investigate the genetic landscape of adult ALL, we performed SNP
array analysis on 126 ALL cases. Characteristic deletions seen in
pediatric ALL were detected, furthermore, comparison of diagnostic
and relapse clonal relationship showed evolution from an ancestral
clone in the majority of cases, highlighting similarities in
childhood and adult disease. In addition, the analysis revealed
several recurrent cryptic genetic events not previously implicated
with adult ALL, including the BCAT1, BTLA, NR3C1, PIK3AP1 and SERP2
genes. In articles II-IV the genetic and epigenetic background of
hypodiploid ALL was further investigated using SNP array analysis,
exome and RNA sequencing, methylation array analysis and FISH
analysis. Characteristic chromosomal patterns were confirmed and
subtype specific alterations targeting IKZF3, NF1, FLT3 and TP53
were identified near-haploid and low hypodiploid respectively.
Furthermore, due to the specific pattern of CDKN2A deletions in one
case, we could conclude that chromosomal loss was the primary event
with further microdeletions occurring after the
near-haploidization. Combining SNP array and FISH analysis, a
sublconal pattern was detected in three cases harboring >79
chromosomes, showing a possible hypodiploid origin due to the
extensive loss of heterozygosity identified in such cases. That all
three cases harbored TP53 mutations emphasized similarities to low
hypodiploid ALL. In conclusion, screening for specific genetic
abnormalities routinely in the clinic may improve prognostication
and treatment stratification in cases with a poor
prognosis.

▼ This report describes a newly-designed molecular method based on the high sensitive techniques Fragment analysis and Quantitative real-time PCR that is able to scan leukemic DNA at very low levels in the blood of patients with pediatric acute lymphoblastic leukemia. Our study presents tracks of leukemic burden at diagnosis and on days 8, 15, 33 when the commonly used markers Bone marrow infiltration and Minimal Residual Disease (MRD) reduce the value (day 8) and eliminate it (days 15 and 33) giving the impression that blasts disappear from patient’s organism. Cell-free leukemic DNA can also be scanned on these days and appears to follow the same procession and behavior as nuclear leukemic DNA although at significantly lower levels.The detection of blasts on days 15 and 33, when the number of white blood cells reduces significantly, is crucial for the progression and response to chemotherapy. The analysis of the methylation status of the promoter of Rassf6 gene reveals a methyl-CpG-domain that carries methylgroups the number of which differs between two major groups of patients. Those with favorable and those with unfavorable outcome. Therefore the detection of nuclear and cell-free leukemic DNA in blood circulation of patients with acute lymphoblastic leukemia using the hypermethylated promoter of Rassf6 gene adds prognostic value to minimal residual disease status and gives hope of potential marker in ALL to become as it follows the reduce of leukemic burden and the presence or absence of blasts in blood circulation during chemotherapy and for long time afterwards.
Στην παρούσα διατριβή μελετήθηκαν καρκινικά κύτταρα από δείγματα ασθενών με οξεία λεμφοβλαστική λευχαιμία παιδικού τύπου. Τα δείγματα ελήφθησαν την ημέρα 0 (πρωτοδιάγνωση) και τις ημέρες 8, 15 και 33 όταν οι ασθενείς υποβάλλονταν σε χημειοθεραπεία. Στις ημέρες αυτές μελετήθηκε το λευχαιμικό πυρηνικό DNA καθώς και το λευχαιμικό cell-free DNA και συγκεκριμένα μελετήθηκε ο υποκινητής του ογκοκατασταλτικού γονιδίου Rassf6 για τον οποίον σχεδιάστηκε ειδική μέθοδος στο Εργαστήριο Ιατρικής Γενετικής, που περιελάμβανε αρκετές τεχνικές (πέψη, fragment analysis, quantitative real-time PCR και Sanger sequencing). Τα αποτελέσματα της μεθόδου έδειξαν την παρουσία καρκινικού DNA και τις 4 ημέρες θεραπείας, εύρημα αξιοσημείωτο καθώς τις ημέρες 15 και 33 οι δείκτες διήθηση μυελού (bone marrow infiltration) και ελάχιστη υπολειμματική νόσος (MRD) μηδενίζονται. Η ποσοτική μέτρηση του λευχαιμικού φορτίου μας δίνει πολύ υψηλές τιμές στην πρωτοδιάγνωση (ημέρα 0) οι οποίες μειώνονται ραγδαίως τις ημέρες 8, 15 και 33 όταν δηλαδή οι ασθενείς υποβάλλονται σε χημειοθεραπεία, παρά το γεγονός ότι και την ημέρα 33, καθώς και τις προηγούμενες ημέρες ανιχνεύεται λευχαιμικό φορτίο το οποίο ποσοτικοποιείται. Τέλος η κατά βάση αλληλούχιση του υποκινητή του γονιδίου Rassf6 μας αποκάλυψε την παρουσία των χημικών ομάδων του μεθυλίου (CH3) ο αριθμός των οποίων διέφερε μεταξύ των ασθενών με θετική έκβαση και των ασθενών που κατέληξαν.

▼ Background: Currently available chemotherapeutic
treatment for relapse/refractory
acute lymphoblastic leukemia (ALL)
helps to achieve complete remission (CR) in only one third of the
patients. The definitive treatment for ALL is allogeneic
hematopoietic stem cell transplant (HSCT) which can be used only in
patients who achieved complete remission with the chemotherapy. We
did the study to explore possibilities for better survival by using
other possible chemotherapeutic regimens in relapsed/refractory ALL
patients. ❧ Methods: Patients with ALL who relapsed or were
refractory to chemotherapy, age range of 17 to 55 years, Karnofsky
performance status of > 50%, and adequate hepatic and renal
function were eligible for the study. The primary objective of the
study was to achieve higher CR rate after the two phases of
induction therapy as compared to standard of care. Secondary
objectives were to achieve longer LFS (
Leukemia free survival),
measure regimen toxicity and decrease number of days required for
neutrophil count recovery after each cycle of induction as compared
to current chemotherapy for relapsed/refractory ALL patients. In an
effort to improve the CR rate in adults ALL cases, a modified
regimen was derived from pediatric Berlin-Frankfurt-Muenster
(BFM)-85 protocol, with addition of a continuous infusional phase
II induction followed by consolidation with alternating monthly
cycles. ❧ Results: In this study, we have included the outcome of
19 patients treated prospectively on the study, as well as a
subsequent cohort of 31 patients treated off the study. Thirteen
out of nineteen (68%) patients from the initial prospective study
achieved CR, and the median overall survival of these 13 CR
patients was 10.3 months. The median survival and LFS of all 19
patients were 5.6 and 4.3 months respectively. The regimen was
well-tolerated and no grade 4 non-hematological toxicity was
observed. Of the 31 patients treated off the study and analyzed
retrospectively, 16 (52%) achieved CR. After including all 50
patients, 29 achieved CR (58%). ❧ Conclusion: The regimen used in
this trial helps to achieve higher CR than the current
chemotherapeutic regimen for relapse/refractory ALL and helps to
use allogeneic-HSCT as a definitive treatment in these
patients.

▼ Ph.D. University of Hawaii at Manoa 2010.
Overall survival for pediatric patients with acute lymphoblastic leukemia (A.L.L.) treated with contemporary therapy now exceeds 85%; however, approximately 20% will experience relapse. Since A.L.L. is the most common malignancy in children, relapsed patients comprise a large proportion of the total number of children with cancer. The prognosis for long-term survival following relapse is generally poor; thus, relapsed A.L.L. is a significant contributor to cancer-related mortality in children.
Poor adherence to oral medication is a substantial problem in contemporary health care and may contribute to unexplained relapses in children with A.L.L. Therapy for pediatric A.L.L. includes a prolonged "maintenance" phase that requires daily 6-mercaptopurine (6MP), a self-or parent/caregiver-administered oral chemotherapy agent given for approximately two years. 6MP has been shown to be a critical component of the curative regimen for A.L.L.; thus, children with A.L.L. who fail to adhere to oral 6MP chemotherapy as prescribed may be at increased risk of leukemia relapse.
This study used extant questionnaire data from a cohort of children with A.L.L enrolled on a Children's Oncology Group study (AALL03N1) to determine the prevalence of self/parent-reported non-adherence to oral 6MP during the maintenance phase of A.L.L. therapy, and to identify sociodemographic and behavioral predictors of non-adherence to oral 6MP.
Twenty-two percent of children in the cohort were non-adherent to oral chemotherapy, defined as missing more than one dose of 6MP for non-medical reasons over the 112-day observation period. The risk of non-adherence was significantly increased for those who failed to perceive the severity of the child's illness (Odds ratio [OR] 1.89, 95% Confidence Interval [CI] 1.00-3.55, P=0.049) or the benefits of treatment with oral 6MP (OR 1.78, 95%CI 1.07-2.94, P=0.025). Vulnerable subgroups included Hispanic ethnicity (OR 2.25, 95%CI 1.30-3.90, P=0.004) and older age (OR 1.07 per year, 95%CI 1.02-1.12, P=0.005).
Study findings suggest that even occasional reports of missed 6MP doses may herald a significant adherence problem; that patients and their parents may need ongoing reminders regarding the subclinical and asymptomatic nature of leukemia in remission; and that frequent review with families regarding the purpose, function, and proper administration of oral 6MP is imperative.

▼ Apoptosis and Autophagy are two processes that play key roles in the death and survival of cells. Apoptosis is a cell death mechanism, where autophagy is a cell survival as well as a cell death mechanism. In this study we investigated whether and how these two processes interact with each other in human
lymphoblastic leukemic cells. Two cell lines were used: the first being CEM C1-15, resistant to dexamethasone-induced apoptotic death. The second cell line being CEM C7-14, sensitive to dexamethasone-induced death. The drug reagent rapamycin, an mTOR inhibitor, was utilized to induce autophagy. Dexamethasone, a synthetic glucocorticoid, was used to induce Apoptosis. Additionally, 3-Methyl Adenine (3MA) was employed to rescue cells from an autophagic fate caused by rapamycin. We show that apoptosis and autophagy collaborate in CEM C1-15 and C7-14 cells, and are able to take place simultaneously in the same cell. We also show that there is a synergistic effect when both processes are induced, resulting in a stronger death response. Moreover, we have used cell growth assay data in conjunction with fluorescent microscopy images to show that when autophagy is inhibited, apoptosis takes over as the primary cell death mechanism. In summary, our results add to the knowledge of apoptotic-autophagic interaction in leukemic cells and show that epifluorescence microscopy is a useful tool in aiding researchers to take specific and detailed images of cellular processes.

▼ Obesity is a recognized problem for children treated for
acute lymphoblastic leukemia (ALL) and is present in roughly one fourth of children by the end of therapy. Obesity may lead to immediate health threats, such as an increased risk for cancer relapse, or may cause future heath issues such as diabetes, metabolic syndrome, hypertension, additional cancers, depression or cardiovascular disease. The purpose of this study was to determine if weight gain during two individual cycles of therapy (Induction or Delayed Intensification Cycle 1) were predictive of obesity (defined as body mass index ≥ 95th percentile for age and gender) at the end of treatment. This study retrospectively examined height and weight data from 1,017 childhood
leukemia patients treated on Children's Oncology Group (COG) protocol number 1961. This study included patients that had fully completed therapy on protocol 1961 and who were between the ages of 2-20 years. Percentiles and z-scores for age and gender specific body mass index (BMI) were calculated using the height and weight measurements obtained at the beginning of each cycle of chemotherapy. Univariate and multivariate logistic regression analyses were performed. BMI z-score at the beginning of therapy and difference in BMI z-score during Induction were significant predictors (p<0.0001) of BMI ≥ 95th percentile at the end of maintenance in both males and females. A one unit increase in the difference of BMI z-score during Induction resulted in a 3.03 odds ratio (OR) for obesity at the end of therapy for males (95% CI, 1.90 to 4.84) and a 4.15 OR for females (95% CI, 2.32 to 7.43). The change in BMI z-score during Delayed Intensification I was not found to be significant in relationship to obesity at the end of therapy. Weight gain during Induction consisted of ≥ 20% increase in weight for 3.9% of the study participants. Weight gain during Induction therapy of childhood ALL treatment may be useful in predicting patients at increased risk for obesity development during therapy. Early identification of these at risk patients can assist with interventions aimed at normalizing weight gain during therapy.

▼ Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Current treatments result in continued complete remission in over 80% of patients, however up to 20% relapse due to small numbers of surviving cells. Measurement of this minimal residual disease (MRD) at day 33 and day 79 is used in a current clinical trial, Australian and New Zealand Childrens Haematology/Oncology Group (ANZCHOG) Study 8 to decide patient treatment risk group. The level of MRD in a remission sample is defined as the amount of amplifiable gene rearrangement relative to the patients diagnosis sample. The hypothesis tested in this study was that MRD level at day 15 is also prognostic of patient outcome. MRD was measured by real-time quantitative PCR detection of immunoglobulin and T-cell receptor gene rearrangements in bone marrow DNA at day 15 from 211 paediatric patients at two hospitals and analysed according to EuroMRD guidelines.Day 15 MRD was highly prognostic of outcome (event-free-survival; EFS) at several thresholds especially at 1x10-2. About 61% of patients (28/46) who relapse have day 15 MRD greater than 1x10-2 and around 44% of patients with MRD above this threshold relapsed or had other events. Even after the exclusion of high risk patients, day 15 MRD was still prognostic of outcome (P=0.0001). It was also able to separate patients into three groups with different prognoses: patients with high MRD (≥1x10-2), lower MRD (<1x10-2) and no detectable MRD with 5-year EFS rate of 57%, 82% and 93% respectively. When day 15 MRD was assessed together with Study 8 risk group and NCI risk group in a multivariate risk analysis, day 15 MRD and NCI risk group retained significance, demonstrating the independent predictive value of day 15 MRD. Both high MRD at day 15 and high NCI risk groups were associated with two-fold increase of relative risk of events.In a Cox multivariate analysis of day 15, 33 and 79 MRD, MRD at day 15 retained significance in predicting subsequent relapse and other events (P=0.0122). Patients with high MRD at both day 15 and day 33 appeared to be at highest risk, andiithe combination (day 15 MRD ≥1x10-2 and day 33 MRD ≥1x10-3) could be used for patient stratification. Patients with undetectable MRD at day 15 could be considered for reduced chemotherapy.The use of a second marker in 37 relapsed patients provided additional useful information for 5 patients. Although limited by small numbers, these findings are consistent with earlier studies which concluded that a second marker is important in ensuring reliable and accurate MRD assessment for patient stratification.It is clear that MRD at day 15 of therapy is predictive of outcome in ALL patients treated on a current Australian MRD intervention protocol. It could be used to identify additional patients at high risk of relapse; and therefore it is suggested that MRD at day 15 should be evaluated for all patients in future clinical trials. Earlier tailoring of treatments to best suit different risk groups could lead to further…

▼ In the United States approximately 3,500 children are diagnosed with
acute lymphoblastic leukemia (ALL) each year (Horton & Steuber, 2012). With a considerable amount of families being affected by ALL annually there is a substantial need to understand how this affects the parents of these children. There have been numerous studies in reference to families dealing with childhood cancers. However, few studies have addressed the topic of parenting a child with ALL and the challenges that arise during this difficult time (Long & Marsland, 2011). More importantly of the reports on parenting a child with ALL, only a few explore the experience from the father???s perspective.
The purpose of this study is to explore paternal and maternal stress levels on parents who are parenting a child with ALL that is undergoing treatment and to explore possible parental gender differences in coping with the stress of parenting a child with ALL undergoing treatment. This study uses the theoretical framework of Richard Lazarus and Susan Folkman???s (1984) theory of stress, appraisal, and coping to explore the experience of parenting a child with ALL.
The research questions explored in this study will be: (1) Is there is a difference in stress levels reported by the mothers and fathers of a child undergoing treatment for ALL? and (2) ???To determine if the demographic variables of the child???s age, the child???s gender, time since diagnosis, and parent???s gender explain the different parenting experiences when parenting a child with ALL?

▼ Acute leukemia (AL) is a rare, potentially curable, aggressive neoplasm of hematopoietic origin. AL is a heterogeneous disease and is further subdivided according to clinical and biological features.
The aims were to investigate: i) the incidence and survival of adult AL in regions with socioeconomic differences, ii) the outcome of acute promyelocytic leukemia (APL) with particular emphasis on the course of disease during the first weeks of diagnosis, iii) the disease characteristics and survival in patients aged 10-30 years, with acute myeloid leukemia (AML).
We have investigated these issues in population-based materials; the first two studies were based on data from the Swedish Cancer Registry and the other four studies were based on data from the Swedish Adult Acute Leukemia Registry (SAALR). Comparisons were made with Estonia on incidence and survival of AL and with the Nordic Society for Paediatric Haematology and Oncology (NOPHO) and adult registries in Denmark and Norway for young AML patients.
The incidence of de novo AL was higher in western Sweden than in Estonia for patients aged ≥ 65 years. The 5-year relative survival for AL in patients aged 16-64 years was better in western Sweden than in Estonia and there was a significant improvement in outcome in western Sweden during 1982-1996. The differences in survival between the regions had decreased during the period 1997-2001; a dramatical improvement of survival was seen in Estonia, while no further improvement was recorded in western Sweden.
In a population-based study of APL, 29% of patients died within 30 days from diagnosis, 41% due to hemorrhage. The early mortality was higher than described in randomized trials.
There were no differences in survival for young AML patients whether treated according to pediatric or adult treatment protocols. Age was not found to be an independent prognostic marker for outcome.
Studies from population-based materials provide real world data, an important complement to data from randomized trials. Observational studies from population-based registries with high coverage can improve the epidemiological knowledge and can also describe unknown problems that need further investigation in randomized trials.

▼ markdownabstract__Abstract__
Despite the improvement in prognosis of childhood acute lymphoblastic leukemia (ALL) due to the implementation of relapse risk stratification, the majoritiy of relapses occurs in cases that were initially not considered as high-risk. Furthermore, current therapies are designed in the fifties and sixties of the past century and result toxicity. Therfore, there is a need for better relapse risk stratification and newly designed drugs that specifcally target leukemic cells. This thesis identifies the interaction and independency of different recently introduced relapse risk markers. It demonstrates that both BCR-ABL1-like gene expression signature and all variants of IKZF1 deletions are correlated to an unfavorable prognosis in B-cell precursor ALL (BCP-ALL). These observations resulted in the implementation of IKZF1 deletions in the currect DCOG ALL-11 treatment protocol. Furthermore, this thesis demonstrates that TCF3-rearranged BCP-ALL is characterized by an activated pre B-cell receptor. This pathway may be used for targetting leukemic cells in future clinical trials.

▼ The t(1;19) chromosomal translocation is present in 5% of acute lymphoblastic leukemia (ALL) cases and leads to expression of the oncogenic transcription factor, E2A-PBX1. Although t(1;19) is exclusively associated with pre-B ALL in clinical cases, murine models produce myeloid or T-lymphoid leukemias, which are not representative of the clinical disease. In this work, we have advanced progress towards the development an E2A-PBX1-driven experimental leukemia model. We initially determined that lineage-negative (lin-) hematopoietic progenitors expressing E2A-PBX1 expression fail to repopulate the B-lymphoid lineage when transplanted into irradiated recipient mice. Furthermore, E2A-PBX1 expressing, lin- fetal liver progenitors (FLPs) fail to differentiate into B-lymphocytes ex vivo. The majority of E2A-PBX1-expressing FLPs manifested an immature phenotype and displayed stem cell factor (SCF)-dependency and enhanced self-renewal. Additionally, these cells retained myeloid potential upon transplantation or stimulation with granulocyte macrophage colony-stimulating factor (GM-CSF). DNA binding was required for the differentiation block, suggesting that E2A-PBX1 target genes are incompatible with B-lineage specification. E2A-PBX1 FLPs had a stem cell like gene expression profile, including up-regulation of the leukemic transcription factors, Hoxa9 and Meis1. These findings explain why E2A-PBX1-driven bone marrow transplant models fail to generate B-lymphoid disease and suggest that future efforts in developing a model of E2A-PBX1-driven pre-B ALL leukemia should focus on expressing E2A-PBX1 subsequent to B-lymphoid commitment.
In an attempt to override the B-lymphoid differentiation block, we next expressed E2A-PBX1 in primary pre-B cells. E2A-PBX1 induced an apoptotic response in pre-B cells, which was consistent with previous observations. Since pre-B ALL induction requires secondary genetic events, we attempted to abrogate these E2A-PBX1-mediated effects by modulating expression of the Cdkn2a locus. Loss of Cdkn2a through deletion or Bmi1 overexpression failed to ameliorate the apoptotic response, suggesting that E2A-PBX1 mediated apoptosis occurs independently of Cdkn2a in murine pre-B cells. However, in the absence of Cdkn2a, co-expression of constitutively active MerTK or Ras attenuated the E2A-PBX1 mediated apoptosis.
Cumulatively, these results support the notion that t(1;19) occurs subsequent to B-lymphoid commitment and requires multiple secondary genetic lesions. Data presented in this thesis represents crucial initiating steps towards the development of a pre-B ALL model mediated by E2A-PBX1.

▼ Bioinformatics is the application of statistics and
computer science to the field of molecular biology The field of
bioinformatics has come to mean the application of mathematics
statistics and information technology to the biological sciences
and the bioinformatics of microarray is the answer to that
challenge In all living organisms the genetic content is encoded in
information units referred to as genes The whole set of genes of an
organism is referred to as its genome The design of microarray
experiments is needed to acquire analyze store and share the
genetic information with other scientists Micro arrays have
acquired special significance in the field of bioinformatics as
they consist of an ordered collection of thousands of different
Deoxyribonucleic Acid sequences that can be used to measure both
DNA and Ribonucleic Acid variations In particular microarrays are
considered a breakthrough technology in biology facilitating the
quantitative study of thousands of genes simultaneously from a
single sample of cells The Gene Expression profiling helps in
understanding the fundamental cause of gene behaviour the growth of
genes identifying new ailments such as cancer and also analysing
their molecular pharmacology DNA microarray technology allows
biologists and medical experts to measure the expressiveness of
thousands of genes of a tissue sample in a single experiment ,
which also helps to identify the cancerous gene However newlinethe
information that is generated from the experiments cannot be
processed or analyzed manually because of its large size and high
complexity In the case of cancer study machine learning algorithms
have become valuable tools to identify the cancerous genes from the
thousands of possible genes Machine learning techniques can be
divided into three major groups based on the types of problems they
can solve namely supervised semi supervised and unsupervised
learning techniques newline newline

▼ Purpose: To identify associations between
specific therapy-related events such as length of hospitalization
and neuropathic pain with health-related quality of life (HRQOL)
outcomes for children with
acute lymphoblastic leukemia and
lymphoblastic lymphoma. Hypothesis: In children
(ages 2 – 30 years) with
acute lymphoblastic leukemia (ALL) or
lymphoblastic lymphoma, poor health-related quality of life (HRQOL)
scores as measured by the PedsQL modules during low-intensity
“maintenance” therapy are significantly associated with increased
care measures during the initial phases of therapy, including
prolonged hospitalization and use of narcotics or neuropathic pain
medications. Specific Aims:1.To evaluate the
relationship between extended hospitalization time (as defined by
total days or weeks admitted, or by number of unanticipated
admissions) during intensive phases of therapy, and HRQOL scores
during maintenance therapy in children ages 2 years and older with
ALL or
lymphoblastic lymphoma. 2. To evaluate the
relationship between increased supportive care for pain by use of
patient-controlled analgesia (PCA), long acting oral narcotics, or
the use of neuropathic pain medications during therapy, and HRQOL
scores during maintenance therapy in children ages 2 years and
older with ALL or
lymphoblastic
lymphoma. Methods: A cross-sectional single
institution pilot study was performed for children with ALL or
lymphoblastic lymphoma who had reached maintenance therapy or had
recently completed treatment. HRQOL scores were obtained using the
PedsQL 4.0 Generic Core Scales and PedsQL 3.0 Cancer Module, and
retrospective chart review was performed for each
patient. Results: 57 subjects were available for
analysis. Multiple regression analysis found that longer total time
of hospitalization correlated with poorer overall PedsQL 4.0
summary scores (p = 0.002). Age, time since the start of
maintenance therapy, and the number of unscheduled hospitalizations
were independently prognostic for physical scores. The use of
neuropathic pain medications was strongly associated with poorer
social functioning scores (OR 4.58, p = 0.03), the number of weeks
hospitalized also negatively influenced social scores (OR 0.90, p =
0.04). Conclusions: Specific therapy-related
events can predict changes in HRQOL outcomes for children and
adolescents with ALL and
lymphoblastic lymphoma. Future research
should include prospective evaluations of HRQOL outcomes throughout
therapy and determine what interventions may improve HRQOL
outcomes.

▼ Background. With achievable
acute lymphoblastic leukemia (ALL) survival rates of
80-90%, non-leukemic events lead to a high proportion of treatment failure. An important cause of morbidity and mortality related to intensified chemotherapy is infection.
Procedure. In this study, the incidence, severity and related pathogen of severe invasive fungal infections (IFI) in the induction and intensification phase reported during the Dutch Childhood Oncology Group (DCOG) ALL-10 protocol were evaluated. IFI grade 3 /4 and grade 5 (death) were reported. Also risk factors for IFI were studied. Additionally, the antifungal policy of all Dutch pediatric oncology centers according to two Dutch national protocols were compared.
Results. Out of 776 patients, 38 cases (5%) of severe IFI were revealed. 35/38 cases (92%) occurred during the induction phase. 33/38 cases (87%) were graded as severe IFI (grade 3 /4), and the others as grade 5. The pathogen was significantly related to the severity of IFI (p = 0.024). In 19 cases (50%) IFI was caused by candida; none of these were fatal. 17/38 (45%) patients had an IFI caused by aspergillus of which 4 were fatal. Regarding all IFI, younger median age (OR, 1.5; CI 0.037;0.834) and Down syndrome (OR, 4.7; CI 1.880;11.545) were risk factors for development of IFI.
Conclusions. Administration of an antifungal agent should be (re)considered during the induction phase. This agent should especially be effective against aspergillus. Younger median age and Down syndrome as risk factor for IFI should be confirmed by other studies.

▼ O papel da vacinação em crianças que receberam quimioterapia (QT) para neoplasias malignas, inclusive leucemia linfóide aguda (LLA), continua controverso. Tanto a doença quanto o tratamento afetam o sistema imune. As alterações podem ocorrer pela neutropenia, que leva ao risco imediato de infecções bacterianas e fúngicas, pela perda dos níveis protetores de anticorpos adquiridos por imunizações prévias, como também pela eficácia duvidosa das reimunizações. Por isso, diferentes abordagens são aplicadas em vários países e o melhor esquema de vacinação não está bem definido. Além disso, as recomendações existentes, construídas principalmente com baixos níveis de evidência, nem sempre são seguidas pelos oncologistas na prática clínica e as referências de literatura quanto ao tema são poucas. A escassez de dados de ensaios controlados, tanto para a imunidade residual contra antígenos vacinais no final do tratamento de crianças com LLA, como para a capacidade desses pacientes responderem aos reforços vacinais, não permitiu até o momento o desenvolvimento de diretrizes, sendo, então, necessárias novas avaliações. Foi realizado um estudo do tipo ensaio clínico controlado aberto, para avaliar as taxas de proteção contra antígenos vacinais virais em crianças tratadas para LLA após término da QT, e da aplicação de uma dose de reforço vacinal. O estado imunológico contra hepatite B, sarampo, rubéola e caxumba foi avaliado em 33 pacientes e comparado com um grupo controle. Para análise estatística foram utilizados o teste do qui-quadrado e exato de Fisher para variáveis categóricas e teste de Mann-Whitney para variáveis contínuas. Observouse uma elevada proporção de indivíduos não imunes ao sarampo (75,9%) à rubéola (51,7%) e à hepatite B (59,3%) ao final da QT para LLA. Após a administração de uma dose vacinal de reforço, ocorreu a recuperação para todos os antígenos testados sendo estatisticamente significante para sarampo (p = 0,0422) e hepatite B (p = 0,0357). Recomenda-se, portanto, uma dose das vacinas tríplice viral e hepatite B após recuperação hematológica e posterior avaliação dos títulos de anticorpos vacinais para intervenções individualizadas.
The role of vaccination in children, who received chemotherapy for malignancies, including acute lymphoblastic leukemia (ALL), remains controversial. Both the disease and treatment affect the immune system. Changes may occur by neutropenia, leading to immediate risk of bacterial and fungal infections, loss protective levels of antibody by previous immunizations, as well as the questionable efficacy of revaccination. Therefore, different approaches are applied in several countries and the best vaccination schedule is not well defined yet. Moreover, the existing recommendations, mainly built on low levels of evidence, are not always followed by oncologists in clinical practice and there are still few references to literature on the subject. The paucity of data from controlled trials on both residual immunity against vaccine antigens at the end of treatment of children with ALL…

▼ Leukemias are the most common form of childhood cancer making up 30% of total pediatric oncological cases, and
Acute Lymphoblastic Leukemia (ALL) makes up a significant portion (12%) of the total pediatric cancer diagnoses. In 2017, the FDA approved a successful immunotherapy called CAR-T therapy for the treatment of pediatric B-cell ALL. This therapy includes a CAR (chimeric antigen receptor) that is loaded into the T-cell and expressed. Currently, the loading of the CAR utilizes viral transduction, but consistency issues lead to adverse symptoms in the patients. Better methods of transduction/transfection are being studied in order to improve these consistency concerns. In this thesis, the efficiency of sonoporation as a non-viral method of transfection was assessed. Fluorescein was loaded as a fluorescent model molecule for beginning understanding of the sonoporation efficiency. It was found that by using sonoporation over electroporation for the uptake of fluorescein, the efficiency is improved by 34%. When sonoporation was used for the transfection of GFP plasmid, the same increase was not proven. This leads to the conclusion that without further optimization, sonoporation is successful at loading small molecule such as fluorescein but not those as large as plasmids. With optimization, sonoporation could eventually be used as a non-viral method to transfect T-cells with CARs for CAR-T therapy and the treatment of ALL in both children and adults.

▼ A Leucemia linfóide aguda (LLA) é caracterizada pela proliferação anormal de células linfóides imaturas e representa a neoplasia mais comum em crianças. A avaliação de fatores prognósticos em pacientes com LLA possibilita a implantação de abordagens terapêuticas diferenciadas. A expressão aberrante dos marcadores CD56, CD57 e CD16 pode ser uma forma de avaliar tal prognóstico. O objetivo deste trabalho foi caracterizar os pacientes com LLA e avaliar a influência prognóstica da expressão aberrante dos marcadores CD56, CD16 e CD57 na LLA. Foram avaliados 40 pacientes, atendidos no Instituto Maranhense de Oncologia Aldenora Bello (IMOAB), em São Luís MA, no período de março de 2010 a outubro de 2011. Os pacientes foram diagnosticados com LLA, segundo os critérios morfo-citoquímicos e imunofenotípicos. A expressão dos marcadores foi determinada através da citometria de fluxo e os dados clínicos foram obtidos através da revisão de prontuários. Dois grupos foram divididos quanto à expressão ou não dos referidos marcadores e comparados em relação às variáveis prognósticas. A média de idade na amostra foi de 6,28 anos, sendo o sexo masculino predominante (60,0%). A média de blastos contados na medula óssea (MO) e sangue periférico (SP) foram de 77,0 e 39,6, respectivamente. A morfologia L1 dos blastos da MO foi a mais frequente (80,0%). O perfil do hemograma, ao diagnóstico, indicou: 24.061 leucócitos/mm3, 56.510 plaquetas/mm3 e 8,0 g/dL de hemoglobina. De acordo com a classificação GBTLI-99, 60,0% dos pacientes se encontravam no grupo de baixo risco de recidiva e ao final da fase de indução do tratamento (D29), 70,0% dos pacientes alcançaram a remissão. Os pacientes portadores de LLA T apresentaram média de idade (10,6 anos; p= 0,0204) e leucometria (48.200/mm3; p= 0,0167) significativamente mais altas do que os pacientes com LLA B. 80,0% dos pacientes expressaram o marcador CD56 e nenhum paciente expressou o CD16 e/ou o CD57. Os pacientes que não expressaram o marcador CD56 tinham idade significativamente maior daqueles que o expressaram (9,3 anos; p= 0,0353). Para os pacientes portadores de LLA B, a média de blastos do SP dos pacientes que expressaram o marcador CD56 foi maior do que a média dos que não o expressaram (41,1; p= 0,0226). Conclui-se que a expressão do CD56 sugere um pior prognóstico para os pacientes com LLA B, em virtude de uma média significativamente maior de blastos contados no SP encontrada no nosso estudo, contudo, um maior número de casos e um maior tempo de observação seriam necessários para enfatizar melhor esta evidência.
The acute lymphoblastic leukemia (ALL) is characterized by abnormal proliferation of immature lymphoid cells and represents the most common cancer in children. The evaluation of prognostic factors in patients with ALL enables the implantation of different therapeutic approaches. The aberrant expression of markers CD56, CD57 and CD16 may be a way to assess this prognosis. The objective of this study was to characterize patients with ALL and to evaluate the prognostic influence…

▼ L-asparaginase has been used for more than three decades in acute lymphoblastic leukemia (ALL) patients and remains an essential drug in the treatment of ALL. Poor response to L-asparaginase is associated with increased risk of therapeutic failure in ALL. However, both the metabolic perturbation and molecular context of L-asparaginase–treated ALL cells has not been fully elucidated. Here we identify that treatment with L-asparaginase results in metabolic shutdown via the reduction of both glycolysis and oxidative phosphorylation, accompanied by mitochondrial damage and activation of autophagy. The autophagy is involved in reducing reactive oxygen species (ROS) level by eliminating injured mitochondria. Inhibition of autophagy enhances L-asparaginase-induced cytotoxicity and overcomes the acquired resistance to L-asparaginase in ALL cells. The ROS-p53 positive feedback loop is an essential mechanism of this synergistic cytotoxicity. Thus, our findings provide the rationale for the future development of combined treatment of L-asparaginase and anti-autophagy drug in ALL patients.

▼ The etiology of childhood cancer remains largely elusive. In rare cases, genetic mutations and environmental exposures such as radiation are known causes. For the vast majority of childhood cancer patients, there is no known cause for their disease. With an increasing number of childhood cancer survivors, the need to understand disease for patients and their families is becoming even more vital. This dissertation will describe three different investigations to understand the role of genetic or inborn factors play in the etiology of childhood cancer.
The first study reviewed investigates family history in acute lymphoblastic leukemia (ALL) patients. Family history information can provide insight into the genetic (and/or shared environmental) basis of an illness. We investigated the association of family history of specific cancers and non-malignant diseases in one of the largest case-control studies of childhood ALL conducted to date. In this study, family history of cancer was not significantly more frequent among ALL cases compared to controls. The likelihood of family history of esophageal cancer was lower in ALL cases as compared to controls but the number of affected relatives was small in both groups and due to multiple comparisons performed in the statistical analysis may not be a true association. For selected non-malignant conditions, significant inverse associations with family history of allergic disease, food and drug allergy, rheumatoid arthritis and risk of ALL were observed.
The second study reviewed focuses on the association of rib anomalies and childhood cancer. Congenital anomalies have been associated with childhood cancer syndromes in many large epidemiological studies using population based registries. This study sought to better understand and more robustly describe the association between childhood cancer and morphological defects of the ribs in a hospital-based case-control United States population. Our results indicate a modest but fairly robust association between rib anomalies (RA) and childhood cancer. RAs were associated with increased odds of the individual cancer types AML, renal tumors, and hepatoblastoma.
The final study reviewed examines common genetic variation associated with pediatric osteosarcoma (OS). A small subset of individuals develop OS due to a hereditary predisposition syndrome such as Li Fraumeni, Retinoblastoma, or Rothmund-Thompson syndrome. Mutations in the TP53, RB, and RECQL4 genes are highly penetrant and can confer up to a 90% chance of developing OS. We hypothesized that single nucleotide polymorphisms (SNPs) in these genes, and those in the same pathways affect risk of OS less drastically. In this analysis, we conducted a case-parent triad study to examine main effects of DNA repair and metabolism genes in pediatric OS. We identified a nonsynonymous SNP in RECQL4 that was most associated with OS although not significantly after correction for multiple comparisons. No significant associations of DNA repair genes previously described were replicated in this…

▼ B cell Acute Lymphoblastic Leukemia (B-ALL) arises from transformation of progenitor B cells. The transcription factor STAT5 plays a critical role in B-ALL, as high STAT5 activation is correlated with poor patient survival. How STAT5 mediates this effect is unclear. Previous studies suggested that STAT5 simply promotes the survival of progenitor B cells. However, other roles for STAT5 in B-ALL have not been explored. This study demonstrates that STAT5 activation drives leukemia in cooperation with defects in a linear signaling pathway emanating from the pre-BCR, including Blnk, Btk, Prkcb, Nfkb1, and Ikaros. Using microarray analysis and chromatin immunoprecipitation followed by high throughput sequencing (ChIP-seq), we demonstrate that STAT5 antagonizes NFκB and IKAROS by opposing regulation of shared target genes. High levels of STAT5 binding was enriched at super-enhancers that are typically associated with an opposing network of B cell transcription factors including PAX5, EBF1, PU.1, IRF4, or IKAROS. The antagonism between STAT5 and NFκB or IKAROS has direct clinical relevance as the balance between these transcription factors affects patient outcome. Patients with high ratios of active STAT5 to NFκB or IKAROS have more aggressive disease characterized by decreased survival. Our studies illustrate how modest perturbations in two opposing transcriptional programs have dramatic consequences for B cell transformation, and that the degree of antagonism between these transcriptional programs correlates with patient survival.

▼ Although cure rates for
acute lymphoblastic leukemia
(ALL) in children are high, relapse of ALL leads to death in
50-95%. Adult ALL patients have a survival rate of only 40%. Even
survived, patients often suffer from late-term secondary toxic
effects of current treatments. Therefore, chemotherapeutic drug
resistance of ALL cells remains a major problem and less toxic and
more efficient therapies are needed. More than 80% of first relapse
of childhood and adult ALL occurs in the bone marrow. Interaction
of normal hematopoietic stem cells with the bone marrow (BM)
stromal cells has been shown to provide mechanical support and
facilitate proliferation and differentiation. BM stromal cells also
provide protection of ALL cells from chemotherapy, thus
contributing to drug resistance due to the lack of efficacy of
current therapies. The exact mechanisms for stroma-mediated
chemoprotection and approaches to address this problem remain
elusive. In chapter two of this thesis, we summarize how we
established a xenograft model of primary ALL cells to evaluate
novel therapies. In chapter three, we use this preclinical model of
primary ALL and focus on integrin alpha 4 as a central adhesion
molecule for stromal-mediated chemoprotection and drug resistance
of ALL. Integrin α4 is known to mediate adhesion of normal and
malignant B-cell precursors in BM stromal cells. However, the
functional modulation of integrin α4 and its consequences for drug
resistance in ALL remains to be examined. According to gene
expression analyses, integrin α4 is overexpressed in ALL patients
and inversely correlated with the survival outcome. Therefore, we
tested whether interference with α4-mediated stromal adhesion might
be a new ALL treatment strategy. For this purpose, two models of
leukemia were used: one pharmacological using antibody, like
Tysabri, and small molecule inhibitor, like TBC3486, to target α4
of primary pre-B ALL and later in chapter 4 a genetic model
(conditional α4 ablation of BCR-ABL1-induced murine
leukemia).
Conditional deletion of α4 sensitized murine
leukemia cell to
chemotherapy, Nilotinib. Adhesion of primary pre-B ALL cells was
α4-dependent and inhibiting α4 sensitized primary ALL cells towards
chemotherapy, VDL. Combination of chemotherapy with Tysabri
prolonged survival of NOD/SCID recipients of primary ALL suggesting
adjuvant integrin α4 inhibition as a novel strategy for pre-B ALL.
Taken together, our data demonstrate that integrin α4-blockade with
adjuvant chemotherapy can eradicate chemotherapy-resistant
leukemia.

▼ textabstractAcute lymphoblastic leukemia (ALL) represents the most frequent malignancy in
childhood. Last decades brought enormous progress in ALL treatment and in the
understanding of ALL biology (see Chapter 1.1 ), but still 20 to 30% of children suffer
from relapse and many of them will ultimately die of disease progression. The currently
used cytomorphological (microscopic) techniques can only detect 1 to 5% of
malignant cells, which is not sufficiently sensitive for identification of patients who are
prone to relapse and who might be rescued by treatment intensification. During the
past 15 years several approaches have been developed for detection of much lower
numbers of malignant cells, i.e. for detection of minimal residual disease (MRD) in
various hematopoietic malignancies (see Chapter 1.2). Monitoring of MRD with sensitivities
of 1 Q-4 to 1 o-6 (i.e. one malignant cell within the background of 104 to 106
normal cells) has significantly higher prognostic value than conventional cytomorphological
techniques and other clinical parameters at diagnosis and is therefore currently
implemented into clinical practice in several hematopoietic malignancies,
including ALL.
In childhood ALL, detection of MRD most frequently relies on patient-specific
immunoglobulin (lg) and T-cell receptor (TCR) gene rearrangements as molecular
markers for PCR studies. The junctional regions of rearranged lg and TCR genes are
unique "fingerprint-like" sequences, which are assumed to be different in each lymphoid
cell and thus also in each lymphoid malignancy. They can be easily identified
and characterized for instance by using heteroduplex PCR analysis (see Chapter
2.2) and direct sequencing.
This thesis aimed at detailed evaluation of lg and TCR gene rearrangements in
ALL with regard to the following aspects:
-characterization of lg/TCR gene rearrangements patterns in precursor-BALL
and T-ALL;
- immunobiological differences between malignant and normal lymphoid cells;
-stability of clonal lg/TCR gene rearrangements at relapse of ALL;
-applicability of lg/TCR gene rearrangements as PCR targets for detection of
MRD.
Virtually all precursor-B-ALL (96%) have rearranged lg heavy chain (/GH) genes.
In most cases (80-90%) this concerns complete VH-DH-JH rearrangements on at
least one allele. Incomplete DH-JH rearrangements could be identified in 22% of
patients, being the sole /GH gene rearrangements in only 5% of patients (see
Chapter 2.3). Most precursor-B-ALL contain lg kappa (/GK) light chain gene
rearrangements (30%) or deletions (50%); 20% of precursor-B-ALL cases even have
lg lambda (IGL) gene rearrangements. Deletions in the IGK genes are predominantly
mediated via the IGK deleting element (Kde) sequence. Such Kde rearrangements
occur in 50% of precursor-B-ALL cases

▼ Acute Lymphoblastic Leukemia (ALL) is the most common cancer in children under
the age of 15. At present, diagnosis, prognosis and treatment decisions are made
based upon blood and bone marrow laboratory testing. With advances in microarray
technology it is becoming more feasible to perform genetic assessment of individual
patients as well. We used Singular Value Decomposition (SVD) on Illumina SNP,
Affymetrix and cDNA gene-expression data and performed aggressive attribute se-
lection using random forests to reduce the number of attributes to a manageable
size. We then explored clustering and prediction of patient-specific properties such
as disease sub-classification, and especially clinical outcome. We determined that
integrating multiple types of data can provide more meaningful information than
individual datasets, if combined properly. This method is able to capture the cor-
relation between the attributes. The most striking result is an apparent connection
between genetic background and patient mortality under existing treatment regimes.
We find that we can cluster well using the mortality label of the patients. Also, using
a Support Vector Machine (SVM) we can predict clinical outcome with high accu-racy. This thesis will discuss the data-mining methods used and their application to
biomedical research, as well as our results and how this will affect the diagnosis and
treatment of ALL in the future.

▼ AIM: To improve survival in patients with glucocorticoid-resistant T-cell acute lymphoblastic leukemia (T-ALL), it is critical to develop new therapeutic strategies to overcome steroid resistance.
MATERIALS AND METHODS: Biochemical and molecular methodologies were used to evaluate whether tissue transglutaminase (TG2) confers steroid resistance in T-ALL.
RESULTS: T-ALL cells were found to express elevated levels of TG2. We went on to generate models of steroid-adaptedsubclonesofT-ALLcelllinesthatwerenotablylesssensitivetosteroidsthantheparental cells. The steroid-adapted subclones showed increased TG2 expression and nuclear factor-κB (NF-κB) activity compared to T-ALL parental cells. Inhibition of TG2 suppressed steroid resistance and improved steroid cytotoxicity in steroid-adapted subclones of T-ALL in association with reduced NF-κB activity.
CONCLUSION: It is important to note that this study identified that possible changes in TG2 expression may serve as a new target aimed at overcoming steroid resistance in T-ALL.

▼ It has been long known that many types of cancers have high metabolic requirements and use reprogrammed metabolism to support cellular activities. The first identified metabolic alteration in cancer cells was elevated glucose uptake, glycolysis activity and lactate production even in the presence of oxygen. This metabolic program, termed aerobic glycolysis or the Warburg effect, provides cells with energy as well as biosynthetic substrates to sustain cell survival and rapid cell proliferation. Cancer metabolism is closely linked to genetic mutations and oncogenic signaling pathways, such as PI3K/Akt, cMyc and HIF pathways. These oncogenic signals can direct metabolic reprogramming while changes in metabolic status can regulate activities of these signaling pathways in turn. In addition to glucose, later studies also found utilization of alternate nutrients in cancer cells, including glutamine and lipids. Glutamine is the second major metabolic fuel and can be converted to various substrates to support cell bioenergetics needs and biosynthetic reactions. Usage of metabolic fuels in cancer cells, however, is variable. While certain cancers display addiction to one type of nutrient, others are capable of using multiple nutrients. The unique metabolic features of cancer cells raise the possibility of targeting metabolism as a novel therapeutic approach for cancer treatment. Using pharmacological inhibitors, previous research has provided corroborating evidence that metabolic stress can impact survival and growth of proliferative cancer cells by regulating cell apoptotic machinery and cell cycle checkpoints. Due to lack of genetic tools and side effects from these inhibitors, however, mechanistic understanding of cell response to metabolic inhibition was limited in these studies. More importantly, how metabolic stress affects cancer progression in a physiological condition has not yet been well investigated. Lastly, current research has not examined metabolic program in indolent cancers and the metabolic requirements and activities in less proliferative cells also remain to be understood. This work examines nutrients utilization in B cell derived
acute and chronic
leukemia (B-ALL and B-CLL). B-ALL is an aggressive form of
leukemia. Using cell lines and primary patient samples, we found B-ALL cells primarily used glucose through aerobic glycolysis, similar to other proliferative cancer cells. B-ALL cells were also more sensitive to inhibition of glycolysis than normal B cells. Employing an untargeted metabolomics profiling in combination with isotope labeled glucose tracing approach, we show in a B-ALL model that genetic ablation of glucose transporter Glut1 partially reduced glucose uptake, sufficiently hindered anabolic pathways and promoted catabolic metabolism. This metabolic shift led to sharply curtailed B-ALL proliferation in vitro and reduced leukemic burden in vivo. Furthermore, this partial inhibition of glucose metabolism sensitized B-ALL cells to apoptotic stimuli and non-cytotoxic metabolic…

▼ Acute lymphoblastic leukemia (ALL) encompasses a spectrum of lymphoid progenitors that have undergone malignant transformation and clonal proliferation at various stages of differentiation. Some cases of ALL have been documented to have prenatal origins and in particular neonatal exposure to various environmental pollutants is associated with increased disease risk, including childhood lymphoma and
leukemia. Dibenzo[def,p]chrysene (DBC) is a polycyclic aromatic hydrocarbon (PAH) and in our laboratory has been established as a transplacental carcinogen in mice, producing aggressive T-cell
lymphoblastic lymphomas, lung, liver, uterine, ovarian, and testicular lesions, depending on timing and dose of exposure.
Investigation of the transplacental and translactational transfer of DBC was warranted following a cross-foster experiment demonstrating the greatest tumorigenic response occurred in offspring both gestating in and nursed by an exposed female. [¹⁴C]-DBC (GD17) dosing was utilized to examine time-dependent alterations of [¹⁴C] in maternal and fetal tissues, excreta, and residual levels at weaning. Fetal tissue levels of [¹⁴C]-DBC equivalents were 10-fold lower than maternal tissue, and after weaning the residual body burden was roughly equivalent in offspring exposed only in utero or only via lactation.
Certain bioactive food components, including indole-3-carbinol (I3C), 3,3'-diindolylmethane (DIM), and sulforaphane (SFN) from cruciferous vegetables have been shown to target cellular pathways regulating carcinogenesis. In the above mentioned DBC initiated model of carcinogenesis, I3C is an effective transplacental chemopreventive agent. We sought to extend our chemoprevention studies in mice to a human neoplasm in cell culture, analogous to the observed murine T-cell lymphomas. Treatment of the human T-ALL cell line CCRF-CEM (CEM) with I3C reduced cell proliferation and viability only at supraphysiologic concentrations whereas DIM, the primary acid condensation product of I3C, had a marked effect at low micromolar concentrations in vitro and reduced growth of CEM xenografts in vivo. Additional T-ALL lines, selected to represent the heterogeneity of the disease, (CCRF-HSB2, Jurkat, and SUP-T1) responded similarly in vitro, demonstrating a potential therapeutic value of DIM in T-ALL.
Given that epigenetic reprograming is especially active during fetal development and that DNA hypermethylation contributes to the etiology of T-ALL we examined genome-wide DNA methylation in CEM. Differential methylation analysis revealed that DIM and I3C alter CpG methylation in unique, yet overlapping, gene targets. DIM treated cells exhibited a dose-dependent decrease in hypermethylation, an observation consistent with an epigenetic mechanism of cancer suppression. Pyroseqencing and RTPCR technologies were utilized to validate changes in DNA methylation and to compare these patterns with a transcriptional response in both novel targets and candidate genes selected from the literature.
Collectively, these studies merited returning…

▼ Somatic mutations in RNA splicing genes are frequent in many haematological malignancies, but are rarer in
acute myeloid leukaemia (AML). However, their roles in leukaemogenesis are poorly described. To gain insights into the functional impact of alternative RNA splicing in
leukemia, I investigated the transcriptomes of patients with matching clinical data.As a first step, I developed a bioinformatics pipeline (henceforth SpliceGX) to quantify alternative splicing (AS) and differentially expressed genes (DEGs) within the same samples. I also developed tools to predict the functional impact of AS on the translated proteins. I then applied SpliceGX to interrogate the role AS in disease severity in AML. I then applied SpliceGX in two additional, novel contexts: to study T-cell
Acute Lymphoblastic Leukaemia (T-ALL) as well as in T cell development.To investigate alternative RNA splicing in AML, I extracted transcriptomic data from two published cohorts; The Cancer Genome Atlas and Clinseq. I identified 222 AS events that were significantly enriched or depleted in adverse- vs. favourable-risk AML patients with ~ 30% resulting in predicted loss of an annotated protein domain. Most AS events resulted in skipped exons with dysregulation of mTOR and integrin signalling in patients assigned as adverse risk by the European Leukaemia Net (ELN). Motif analysis of alternatively spliced junctions showed usage of non-canonical splice sites. Integrating AS with DEG in adverse- vs. favourable-risk AML further showed that aberrant splicing, even in the absence of known splicing factor mutations, triggers a stress response and the up-regulation of inflammatory genes in AML patients with poor prognosis. Furthermore, using machine learning, I discovered four alternatively spliced transcripts of prognostic significance in AML.Using SpliceGX, I identified characteristic splicing signatures at each waypoint during healthy T cell development, which affected various pathways responsible for cell growth, differentiation, and lineage commitment of thymocytes. In T-ALL, I discovered aberrant splicing of leukaemia driver and splicing factor genes, which indicate that in T-ALL deregulation of cancer genes occurs primarily at the level of splicing, rather than via somatic mutations.In summary, I have developed a bioinformatics pipeline and surveyed RNA splicing in AML and healthy T cell/T-ALL and identified specific events of interest that could be of value as therapeutic targets.

▼ A Leucemia Linfóide Aguda (LLA) é uma doença heterogênea em relação à biologia e ao prognóstico. Além de alterações genéticas, anormalidades epigenéticas, estão estreitamente relacionadas ao processo de carcinogênese e entre os mecanismos epigenéticos, a acetilação das histonas é um componente essencial para a regulação da estrutura da cromatina e atividade transcricional. Esse processo é mediado pelas histonas acetiltransferases (HATs). Por outro lado, a desacetilação, por meio das histonas desacetilases (HDACs), está relacionada à condensação da cromatina e repressão transcricional. A expressão anormal das HDACs tem sido associada ao processo de leucemogênese, revelando ser uma área promissora na caracterização de grupos de risco e tratamento do câncer. Os objetivos deste trabalho foram avaliar a expressão dos genes da classe I de HDACs (HDAC 1, 2, 3 e 8), correlacionar os resultados com as características clínicas e de prognóstico (idade, gênero, grupo de risco, contagem inicial de blastos, imunofenótipo, resposta ao tratamento, doença residual mínima nos dias 14 e 18 e a sobrevida livre de eventos) em 46 amostras consecutivas de medula óssea de crianças e adolescentes portadores de LLA; comparar e correlacionar a expressão dos genes estudados entre as amostras de pacientes portadores LLA e 10 amostras de medula óssea sem doença hematológica. A análise da expressão gênica foi realizada através da técnica de PCR em Tempo Real pelo método TaqMan®. Foi observado um aumento da expressão do gene HDAC1 nas amostras dos pacientes bons respondedores ao ix tratamento. O gene HDAC2 foi mais expresso no grupo de pacientes do gênero masculino (p=0,038). Esse gene também mostrou uma expressão aumentada nos pacientes de alto risco (p=0,060) e com sobrevida menor (p=0,065), entretanto os valores encontrados não foram estatisticamente significativos. Além disso, foi observada uma expressão aumentada dos genes HDAC2 (p=0,007), HDAC3 (p=0,014) e HDAC8 (p=0,002) em amostras de pacientes com LLA quando comparadas às amostras de medula óssea sem doença hematológica. Houve correlação entre a expressão de todos os genes de classe I das HDACs, exceto entre HDAC1 e HDAC8. Os resultados obtidos nesse trabalho sugerem que as HDACs de classe I, podem representar importantes alvos para futuros estudos em LLA, no entanto são necessários de testes funcionais para confirmar estes resultados.
Acute Lymphoblastic Leukemia (ALL) is a heterogeneous disease with distinct biologic and prognostic groups. In addition to genetic alterations, epigenetic processes play an important role in carcinogenesis, among which histone acetylation/deacetylation is crucial for chromatin modulation structure and transcriptional activity. Histone acetylation is regulated by the enzyme histone acetyl transferases (HATs). On the other hand, the deacetylation process is regulated by histone deacetylases (HDACs) enzymes, which is associated with the chromatin condensation and transcriptional repression. Abnormal expression of HDACs is a common feature of cancer and has…
