TLDR
These findings suggest that Blimp-1 promotes plasmacytic differentiation by extinguishing gene expression important for B cell receptor signaling, germinal center B cell function, and proliferation while allowing expression of important plasma cell genes such as XBP-1.About:

TL;DR: In this paper, the authors discuss the unique physiology of ASC and how nBs undergo epigenetic and genome architectural reorganization to acquire the necessary functions to support antibody production, and discuss the stagewise manner in which reprogramming occurs across cell divisions and how key molecular determinants can influence B cell fate outcomes.

Clinical and Molecular Properties of Human Immunodeficiency Virus-Related Diffuse Large B-Cell Lymphoma
TL;DR: In this article, the authors address the clinical and molecular properties of DLBCL disease in the context of HIV infection, as well as the mechanisms by which HIV is able to modulate B lymphocytes and induce their transformation into lymphoma.

Constitutive CD40 Signaling Calibrates Differentiation Outcomes in Responding B Cells via Multiple Molecular Pathways
TL;DR: CD40 signaling induces miR-125b that targets Blimp-1 transcripts, and increases amounts of the ubiquitin ligase Hrd1 that targets BLIMP-1 protein for proteasomal degradation, and constitutive CD40 signaling in vivo involving bystander T–B interactions can calibrate B cell differentiation outcomes.

Cluster analysis and display of genome-wide expression patterns
TL;DR: A system of cluster analysis for genome-wide expression data from DNA microarray hybridization is described that uses standard statistical algorithms to arrange genes according to similarity in pattern of gene expression, finding in the budding yeast Saccharomyces cerevisiae that clustering gene expression data groups together efficiently genes of known similar function.

TL;DR: It is shown that there is diversity in gene expression among the tumours of DLBCL patients, apparently reflecting the variation in tumour proliferation rate, host response and differentiation state of the tumour.

Class Switch Recombination and Hypermutation Require Activation-Induced Cytidine Deaminase (AID), a Potential RNA Editing Enzyme
Masamichi Muramatsu,Kazuo Kinoshita,Sidonia Fagarasan,Shuichi Yamada,Yoichi Shinkai,Tasuku Honjo +5 more
TL;DR: Results suggest that AID may be involved in regulation or catalysis of the DNA modification step of both class switching and somatic hypermutation in CH12F3-2 B lymphoma.

TL;DR: It is demonstrated that mutations in either ire-1 or the transcription-factor-encoding xbp-1 gene abolished the UPR in Caenorhabditis elegans, suggesting that physiological ER load regulates a developmental decision in higher eukaryotes.

c-Myc target genes involved in cell growth, apoptosis, and metabolism
TL;DR: The c-myc gene was discovered as the cellular homolog of the retroviral v- myc oncogene 20 years ago and found to be activated in various animal and human tumors, suggesting that it is critical for development.
