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:MCL lines were treated with or without 100ng/ml doxycycline for 7 days This experiment is designed to see if shRNA-mediated knockdown of NIK downregulates NFKB signaling in MCL lines with mutations in upstream regulators of the alternative pathway (TRAF2 & TRAF3)

Project description:The genome of mantle cell lymphoma (MCL) is, in addition to the translocation t(11;14), characterized by a high number of secondary chromosomal gains and losses that likely account for the varying survival times of MCL patients. We investigated 77 primary MCL tumors with available clinical information using high resolution RNA expression and genomic profiling and applied our recently developed gene expression and dosage integrator (GEDI) algorithm to identify novel genes and pathways that may be of relevance for the pathobiology of MCL. We show that copy number neutral loss of heterozygosity (CNN-LOH) is common in MCL and targets regions that are frequently affected by deletions. The molecular consequences of genomic copy number changes appear complex, even in genomic loci with identified tumor suppressors, such as the region 9p21 containing the CDKN2A locus. Moreover, the deregulation of novel genes such as CUL4A, ING1 and MCPH1 may affect the two crucial pathogenetic mechanisms in MCL, the disturbance of the proliferation and DNA damage response pathways. Deregulation of the Hippo pathway may have a pathogenetic role in MCL, since decreased expression of its members MOBKL2A, MOBKL2B and LATS2 was associated with inferior outcome also in an independent validation series of 32 MCL.

Sixty-four primary MCL specimens from previously untreated patients were investigated with Affymetrix HG U133 plus 2.0 gene expression arrays.

Project description:Ibrutinib, a bruton's tyrosine kinase inhibitor, was shown to have high response rates in mantle cell lymphoma (MCL), an aggressive B-cell lymphoma. However, emergence of ibrutinib resistance (IR) and subsequent fatal progression is of significant clinical concern. By implementing genomics, chemical proteomics and drug screening, we report that enhancer remodeling-mediated transcriptional activation and adaptive signaling changes drive the malignant phenotype of IR. Accordingly, IR MCL cells are vulnerable to inhibition of the transcriptional machinery and especially to inhibition of cyclin-dependent kinase 9 (CDK9). Thus, targeting transcriptional activation offers a novel strategy to prevent the emergence of IR and overcome IR via impeding IR-associated cellular signaling reprogramming in MCL. In addition, our ex-vivo microfluidic image-based functional drug screen can function not only as new technology platforms for predicting clinical therapeutic response but also, in conjunction with genomic profiling in primary MCL samples, identify the molecular vulnerabilities for drug resistance evolution, providing insight into the underlying IR mechanisms for MCL and other B-cell malignancies
