Abstract:
The rapid emergence of molecularly based techniques to detect changes in the genetic landscape of diffuse large B cell lymphoma (DLBCL), including gene expression, DNA and RNA sequencing, and epigenetic profiling, has significantly influenced the understanding and therapeutic targeting of DLBCL. In this review, we briefly discuss the new methods used in the study of DLBCL. We describe the influence of the generated data on DLBCL classification and the identification of new entities and altered cell survival strategies, with a focus on the renewed interest in some classic oncogenic pathways that are currently targeted for new therapy. Finally, we examine the molecular genomic studies that revealed the importance of the tumor microenvironment in the pathogenesis of DLBCL.

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
