Full textMantle Cell Lymphoma (MCL) is a recently defined entity, typically characterised by the genetic translocation t(11 ;14)(q13 ;q32) and counting for 2 - 10% of all non-Hodgkin Lymphomas. With a median survival between 3 and 5 years after diagnosis, MCL is an agressive disease and despite the recent therapeutic advances little in know about its prognostic factors. Some studies had investigated clinicopathological features and new treatment strategies, but there is a lack of knowledge regarding the impact of lifestyle and environnemental factors on outcome of MCL patients. From 2008 to 2012, the LYSA Group conducted in France two prospective multi center clinical trials on MCL : LM manteau 2010 SA "RiBVD" (NCI01457144) and Manteau 2007 SJ "LyMa" (NCT00921414). After a comparison of these patients with population-based data, socioeconomic factors, lifestyle factors and their influence on survival had been investigated through a qualitative survey administrated to each volunteer after diagnosis. Our findings suggest that low educational attainment, low body body mass index and alcohol consumption are associated with a higher risk of death in MCL. However, to investigate lifestyle factors in this rare NHL subtype, larger studies should be carried out. Clinical trial inclusion criteria must be widen to select more patients and patients more representative of general population. Implementation of these epidemiological studies in clinical practice should be considered

Full textMantle cell lymphoma (MCL) is a mature malignant hemopathy, belonging to the non-Hodgkin's lymphoma family. The MCL is characterized by the translocation t(11;14)(q13;q32) which causes an aberrant expression of cyclin D1. It is a rare disease but at high risk of relapse, and it is most often incurable due to the appearance of chemoresistant clones. The acquisition of resistance is intimately linked to the interactions between the tumor cells and their microenvironment. In order to mimic, in the most relevant way, these interactions, we have implemented a mouse xenograft model using the MCL cell lines JeKo1, REC1, Z138 and Granta-519 which we have modified so that they express a fluorophore (GFP or m-cherry) and / or the gene encoding the luciferase. After injection to the mice of the luciferase substrate, luciferin, we are able to follow over time the tumor progression. We can also assess the degree of tumor infiltration in bone marrow, spleen, brain and blood after euthanasia of animals, by flow cytometry and immunocytochemistry. This model allowed us to show the therapeutic interest of an inhibitor of exportin 1 (XPO1): the KPT 330 (or selinexor) which is able to contain cyclin D1 only on the nuclear level. We have shown that the subcellular localization of cyclin D1 is mainly cytoplasmic in some LCM (2/7) cell lines and in a number of patients (6/42, 14%), and is associated with a high potential Invasion, migration and an aggressive phenotype. Moreover, thanks to this model, we have been able to objectify the in vivo lack of efficacy of agonists to β-type estrogen receptors (ER β). These receptors, present on B lymphocytes, were thought to inhibit cell proliferation and cause cell death by apoptosis. The use of two ER β agonists, diarylpropionitrile (DPN) and ERB-041 showed an absence of effect of these molecules, when the tumor cells are in contact with their microenvironment. On the other hand, in order to better understand the mechanisms of resistance to chemotherapies, we studied the resistance of the REC-1 cell line treated with genotoxic agents. We have shown that this line has an abnormality of cyclin D1 degradation associated with decreased activity of the 26S proteasome. Finally, we have shown in preliminary work that the fused in sarcoma protein (FUS) could, when associated with cyclin D1, be able to regulate the repair pathways of DNA damage. Abnormalities of these pathways induce a great genetic instability responsible for the escape of tumors to treatments, the targeting of FUS could therefore be of therapeutic interest.Taken as a whole, these results reinforce or invalidate the interest of certain therapeutic targets in the hope of continuing to improve the management of patients. They also provide a tool for evaluating new molecules in a murine model that takes into account the interactions between the tumor cell and its microenvironment

Full textCyclin D1 is a protein involved in cell cycle regulation and transcription. It is expressed in some hematological B lymphoid neoplasms: multiple myeloma (MM), mantle cell lymphoma (MCL) and hairy cell leukemia (HCL), but not in B cells. Cyclin D1 is encoded by CCND1 gene and transcribed by alternative splicing in two forms (a and b). The proteins cyclin D1a and b differ in the N-terminal region involved in degradation and subcellular localization. We studied the expression of cyclin D1 RNA and protein in three B hemopathiesl (MM, MCL and HCL). Cyclin D1b is mainly present in MCL and rarely in MM. The rate of transcript a is higher than transcript b. The half-life of both isoforms is similar and both proteins are present in nucleus and cytoplasm. Cyclin D1b has not the properties (stability, localization) associated with its tumorigenic potential. Thus, cyclin D1b does not appear to play a role in the pathophysiology of MM and MCL. To characterize the mechanisms of action of cyclin D1a, we transduced the protein in various MM and lymphoma cell lines with no endogenous cyclin D1 and representative of various levels of differentiation. Transduction of exogenous cyclin D1 leads to an increase of proliferation rate of pro-B cell lines (NALM-6, 697) and a block of cell cycle in B cell line (RAMOS) and MM cell lines (OPM2, LP1). The latter effect is also observed after transduction of cells with a mutated cyclin D1 protein (K112E). This argue for an effect independent of the phosphorylation of pRb. This effect could be mediated by the activation of the DNA binding subunit p65 and c-Rel of NF-kappaB. In the future, we have to look for new binding partners or transcriptional targets of cyclin D1

Full textLymphoma is a cancer of the lymph nodes which are organs in which immune cells, particularly the antibody producing B cells, proliferate and differentiate before circulating in the blood and tissues to fight infection. B cell lymphoid cancers – ‘B cell lymphoma’ arise as a consequence of the occurrence of gene mutations in B cells. By affecting the functions of key B cell genes, these mutations drive the malignant transformation of the affected B cells which then begin to divide abnormally eventually destroying normal lymph node organization and function. The lymph node is divided into distinct micro-anatomical compartments or zones which are called (from the inner to outer most compartment – germinal centre, mantle zone, and marginal zone). B cell lymphoma classification follows this general organization and classifies tumours depending on the compartment of origin of the particular tumour B cell population. This classification thus defines lymphoma according to a ‘histological subtype’ with defined clinic-biological features. Among these subtypes, mantle cell lymphoma (MCL) is a particularly aggressive form of B lymphoid cancer. This type of lymphoma is characterised by successive relapses and short survival (median is 4 to 5 years), although some patients can show long survival. Predictive biomarkers of this clinical behavior are lacking. This project aims to address this question. More specifically we propose to perform whole ‘exome’ sequencing – i.e. sequencing of all protein coding sections of all known protein coding genes in the genome – of the tumour B cell DNA from patients who show refractory or early relapsing disease compared to patients who show relatively long survival. By doing this genome scale study we hope to identify new gene mutations that can serve as molecular predictors of survival and bring new knowledges in the understanding between genetics and epigenetics in MCL

Full textThe PI3K / AKT / mTOR pathway is the target of Temsirolimus. However, important resistance is observed. We tried to obtain a more important inhibition of PI3K / AKT pathway using two new molecules :- NVP-BEZ 235 (BEZ) which inhibits both mTORC1 and PI3K- AZD8055 (AZD) an inhibitor of mTORC1 and mTORC2 complexes. Using different cell lines of MCL, we have shown that the effect of these new inhibitors on cell survival was more important than that of Temsirolimus. This is probably because contrary to Temsirolimus, the two new molecules can inhibit AKT and 4EBP phosphorylation. In the second part of this project we studied the synergy between the m-TOR kinase inhibitors and aracytine (conventional treatment of MCL). We revealed a significant additive effect in MCL cell lines. We demonstrated by Western blot analysis that aracytine inhibits S6 and 4EBP phosphorylation. This may explain the results obtained from this drug association. We then showed that Ibrutinib (an inhibitor of Btk pathway) can induce a significant inhibition of cell survival when combined with aracytine. In this study, Ibrutinib proved antagonist effect to PI3K-AKT-mTOR inhibitors. The mechanisms of these results remain unclear. Finally, we demonstrated an additive effect of Ibrutinib in combination with doxorubicin. We did not obtain the same results when we combined m-TOR inhibitors with doxorubicin. To explain these data, we studied the effect of these drugs on the expression of GSTPi by western blot. This enzyme is known to have an important role in MCL resistance to anthracycline. Importantly, Ibrutinib induced a decrease in the expression of GSTPi but AZD8055, Temsirolimus and NVP-BEZ235 had no effect

Full textMantle cell lymphoma (MCL) is a rare disease displaying a great diversity in terms of clinic, biology and response to therapies. Currently, immunochemotherapy and consolidation by autologous hematopoietic stem cell transplantation is the standard treatment proposed to all younger patients, yet about 10% are refractory while others enjoy long remissions. The development of new prognostic markers could help to adapt a personalized approach of therapeutic strategies. In the first part of this document, fundamental and scientific aspects of this disease are described The second part reports the results obtained in the context of this thesis. The prognostic value of chromosomal copy number anomalies intrinsic to the tumor cells was investigated in 100 MCL patients enrolled for first-line therapy in the LyMa clinical trial. This pan-genomic approach, performed on highly degraded tumoral DNA by SNP-array, allowed to identify that 7p22 gains are associated to a good response is spite of the presence of high-risk anomalies (TP53 or CDKN2A deletions). We also identified that gains of CCND1, corresponding to additional copies of CCND1/IGH rearrangements, are associated to poor response to therapy. These data were confirmed in a second independent cohort of MCL patients. This work has been published..Investigations in progress are also presented. In the same LyMa cohort, the role of CDKN2A and p16INK4 anomalies is being evaluated, in correlation with immunohistochemistry. Overexpression of the p16INK4A protein or homozygous deletion of CDKN2A have been characterized, that could be used as prognostic biomarkers at diagnosis, to predict the patient’s response to first line therapy. Finally, we used a novel approach of transcriptomic analysis by Reverse Transcriptase Multiplex Ligation-dependent Probe Amplification (RT-MLPA), adapted to the degraded nucleic acids of our formalin-fixed paraffin-embedded samples. Variations intrinsic or extrinsic to the tumor cell have been explored. Quantitative anomalies of monocytes/macrophages, as well as T and NK cells have been observed, in comparison to non-tumoral samples. Other variations have been identified to be associated to aggressive forms of the MCL, in case of p53 anomalies or at relapse. A third part announces projects envisioned in the future. An analysis of the clonality of tumor-infiltrating T-cells should allow to better understand the immune context of MCL. Finally, a combined analysis of intrinsic and extrinsic anomalies at the single cell level could allow to identify new therapeutic targets and new biomarkers for a better-adapted management of patients

Full textPrimary central nervous system lymphoma (PCNSL) belongs to the systemic diffuse large B-cell lymphoma family. It can affect meninges as well as cranial, spinal, and peripheral nerves, but most frequently, it develops into the brain and/or eye. Primary cerebral lymphoma (PCL) and primary intraocular lymphoma (PIOL) are highly aggressive malignancies with a dark prognosis. Although the important advances founded from the pathogenesis of extraneural non-Hodgkin's lymphoma, the unique organotropism of PCL/PIOL remains poorly understood. Diagnosis now is facilitated by modern imaging techniques and molecular markers, but remains difficult in particular with PIOL as it is a “uveitis masquerade syndrom”. Moreover, in spite of remarkable progress through methotrexate-based chemotherapy, the majority of patients experience relapses within a few years. Better diagnostic tools are required for earlier diagnosis and monitoring of treatment response, and a deeper understanding of the pathogenesis of primary nervous system lymphoma may reveal new therapeutic targets. My PhD project was first to find new cytokine combinations as diagnostic and prognostic markers and then to explore new immunotherapeutic strategies on PIOL and PCL preclinical mouse models. Using vitreous and aqueous humor samples from French and Tunisian patients, we define a new highly discriminative combination of the IL-10/IL-6 and IL-10/IFNγ ratios between PIOL and uveitis patients. Besides, we show an encouraging therapeutic effect of a novel glycoengineered anti-hCD20 antibody in PCL and PIOL murine lymphomas, and intriguing differences in B-cell lymphoma responsiveness to CpG
