Transcription profiling by array of TET2 wild type and TET2 mutant patients with diffuse large B-cell derived lymphoma

ABSTRACT: Global gene expression in TET2 mutant and Wild type patients. We performed an integrated analysis of global DNA methylation and gene expression data to investigate the effects of DNA hypermethylation on gene expression. Total RNA was isolated from 4 TET2mut and 5 TET2wt were isolated using standard RNAeasy kit protocol (Qiagen). Their gene expression profiles were obtained using the[HuGene-1_0-st] Affymetrix.

The discovery that the Ten-Eleven Translocation (TET) hydroxylases cause DNA demethylation has fundamentally changed the notion of how DNA methylation is regulated. Clonal analysis of the hematopoetic stem cell compartment suggests that TET2 mutations can be early events in hematologic cancers and recent investigations have shown TET2 mutations in diffuse large B-cell lymphoma. However, the detection rates and the types of TET2 mutations vary, and the relation to global methylation patterns has  ...[more]
