Development and application of a new immunophenotypic algorithm for molecular subtype classification of Diffuse Large B-Cell Lymphoma (DLBCL): Report from an International DLBCL Rituximab-CHOP Consortium Program Study

ABSTRACT: We studied 498 de-novo adult DLBCL cases, which had been diagnosed between January 2002 and October 2009, as part of the International DLBCL Rituximab-CHOP Consortium Program Study We perform global gene expression profiling from formalin fixed paraffin embedded 498 DLBCL tissues RNA by SPIA mediated microarray detection and identified the distinct subgroups of the disease within DLBCL, known as germinal-center-B-cell-like (GCB), activated B-cell-like (ABC), and unclassified DLBCL (UC). RNA of 498 FFPET DLBCL patient samples were extracted, amplified using a novel RNA amplicfication method, Single Primer Isothermal Amplification (SPIA, NuGen Inc.), and hybridized to Affymetrix HG-U133 Plus 2.0 GeneChips. This dataset is the collaboration between The University of Texas at MD Anderson Cancer Center and Roche Molecular Systems, Inc.

Microarray Innovations in LEukemia (MILE) study: Stage 2 data

Project description:An International Multi-Center Study to Define the Clinical Utility of MicroarrayâBased Gene Expression Profiling in the Diagnosis and Sub-classification of Leukemia (MILE Study) Established in 2005, the MILE (Microarray Innovations in LEukemia) study research program included 11 participating centers in three continents. This cohort of n=1,152 samples represents data on the retrospective whole-genome analysis phase. This dataset is part of the MILE Study (Microarray Innovations In LEukemia) program, headed by the European Leukemia Network (ELN) and sponsored by Roche Molecular Systems, Inc. 1,152 blood or bone marrow samples of acute and chronic leukemia patients were hybridized to the Roche AmpliChip Leukemia Custom Microarray

Expression data from iMyc mouse B lymphoma and human DLBCL

Project description:Cross-species comparative gene expression profiling was performed to identify differentially expressed genes conserved in aggressive B lymphomas. Whole genome expression arrays from mouse B220+ splenic B cells (wild-type C57BL/6, B6) were compared to whole tumors (approximately >75% neoplastic cells) from B6.iMyc mice. Correspondingly, isolated human peripheral blood B cells were compared to human diffuse large B cell (DLBCL) whole tumors (approximately >75% neoplastic cells) DLBCL.

Whole-transcript expression data from normal and DLBCL human peripheral blood samples

Project description:Gene expression profiling based classification of DLBCL patients versus healthy donors provides insights on transcriptional regulation processes. Within the most represented pathways in DLBCL, we identified an innate immune response signature, as well as an anti-inflammatory response. On the other hand, a significant under-representation of pathways involved in T-cell activation was also revealed. Whole blood from 76 DLBCL patients and 87 healthy donors was collected into PAXgene Blood RNA tubes (Becton Dickinson BD Biosciences, San Jose, CA, USA) ensuring blood stabilization and stored at -80Â°C before RNA extraction. Total RNA, after globin mRNA depletion, was hybridized onto Affymetrix GeneChipÂ® Human Exon 1.0 ST oligonucleotide arrays (Affymetrix, Santa Clara, CA, USA) according to manufacturerâs instructions.
