Massive Transcriptional Perturbation in Subgroups of Diffuse Large B-cell Lymphomas

LHA-ID
7RU86AHFM0-8
Motivation

Based on the assumption that molecular mechanisms involved in cancerogenesis are characterized by groups of coordinately expressed genes, we developed and validated a novel method for analyzing transcriptional data called Correlated Gene Set Analysis (CGSA). Using 50 extracted gene sets we identified three different profiles of tumors in a cohort of 364 Diffuse large B-cell (DLBCL) and related mature aggressive B-cell lymphomas other than Burkitt lymphoma.

Description
72 samples from normal cells and lymphoma cell lines including: 8 samples of naïve B cells, 13 samples of germinal center (GC) B cells, 9 samples of postGC B cells, 10 tissue samples of tonsils and 32 samples of 28 different lymphoma cell lines were hybridized to HGU133A Affymetrix GeneChips.
Overall Design

We analyzed a cohort consisting of 364 DLBCL and related mature aggressive B-cell lymphomas other than Burkitt lymphoma. All cases of this cohort were collected within the network project Molecular Mechanisms in Malignant Lymphoma (MMML).
