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


ABSTRACT: 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 -80°C before RNA extraction. Total RNA, after globin mRNA depletion, was hybridized onto Affymetrix GeneChip® Human Exon 1.0 ST oligonucleotide arrays (Affymetrix, Santa Clara, CA, USA) according to manufacturer’s instructions.

In diffuse large B-cell lymphoma (DLBCL), the number of circulating monocytes and neutrophils represents an independent prognostic factor. These cell subsets include monocytic and granulocytic myeloid-derived suppressor cells (M- and G-MDSCs) defined by their ability to suppress T-cell responses. MDSCs are a heterogeneous population described in inflammatory and infectious diseases and in numerous tumors including multiple myeloma, chronic lymphocytic leukemia, and DLBCL. However, their mechanis  ...[more]
