Project description:Gene expression analyis of primary MCL including IGHV mutated and unmutated cases Gene set analysis was perfomed in MCL samples, comparing IGHV mutated cases vs. IGHV unmutated cases In total 38 MCL samples were processed with the HU133plus 2.0 microarray. Twenty four cases had a IGHV mutations and 14 were unmutated.

Project description:Stabilizing mutations of NOTCH1 have been identified in about 10% of chronic lymphocytic leukemia (CLL) cases at diagnosis, with a higher frequency in unmutated IGHV (IGHV-UM) CLL, chemorefractory CLL and CLL in advanced disease phases. Clinically, the presence of NOTCH1 mutations is an independent predictor of overall survival in CLL and associates with resistance to anti-Cd20 immunotherapy. The Gene Expression Profile was generated to identify the peculiar molecular signatures of NOTCH1 mutated CLL in the context of IGHV-UM CLL. Constitutive gene expression in CLL cells bearing or not NOTCH1 mutation (c.7541_7542delCT). Five samples were selected for each category (WT vs MUT).

Project description:In the present study, the methylation profiling (MeDIP) was carried out in 14 treatment-naive, early stage (Rai stage 0-2) CLL patients and pooled 19+ normal controls. To find an association of methylation with IGHV mutation status, CLL patients were further segregated into IGHV unmutated (n=9) and IGHV mutated (n=5) subgroups. The methylation signature obtained for CLL versus nornal controls and; unmutated versus mutated CLL was integrated with gene expression profile of these patients and the results were correlated with clinical outcome.

Project description:Loss of function mutations in the histone methyltransferase KMT2D are common in lymphomas but difficult to target. We reported targeting KDM5 restores epigenetic balance in germinal centre (GC) lymphomas. Here, we show the KDM5 family are over-expressed in mantle cell lymphoma (MCL). GS716054, a pro-drug, increases H3K4 trimethylation (H3K4me3) and kills MCL cells including TP53 mutated cells via suppression of the MYC pathway. It can overcome ibrutinib resistance and synergises with ibrutinib. These data suggest a possible role for KDM5-inhibitors in advanced MCL.

Project description:Mantle cell lymphoma is characterized by a t(11;14) chromosomal translocation; however, it alone is insufficient to result in the disease. A number of secondary genetic alterations have been proposed as essential in MCL pathogenesis. Amongst these, numerous copy number altered regions remain ill-defined, both for location and prognostic significance. In this study we examined in detail the genomes of a panel of 52 MCL cases. Relating gene dosage alterations to disease outcome, we found seven loci that correlated with overall survival. A survival model was constructed based on four of these loci (P = 5.87 x 10-6). Using serial analysis of gene expression and quantitative PCR we investigated the expression of genes within these altered regions and determined that CCNI and CCNG2 may be important in MCL pathogenesis (P = 0.0201 and P = 0.0292, respectively). Our findings reinforce the hypothesis that cell cycle deregulation and apoptosis are key factors in MCL pathogenesis. Array CGH, Long-SAGE, and qPCR were utilized to determine regions of the genome that have prognostic significance when altered in copy number in MCL.
