Transcriptional stalling in B-lymphocytes
B cells utilize three DNA alteration strategies-V(D)J recombination, somatic hypermutation (SHM) and class switch recombination (CSR)-to somatically mutate their genome, thereby expressing a plethora of antibodies tailor-made against the innumerable antigens they encounter while in circulation. Of these three events, the single-strand DNA cytidine deaminase, Activation Induced cytidine Deaminas...
متن کاملRunx3-mediated Transcriptional Program in Cytotoxic Lymphocytes
The transcription factor Runx3 is highly expressed in CD8(+) T and NK cytotoxic lymphocytes and is required for their effective activation and proliferation but molecular insights into the transcription program regulated by Runx3 in these cells are still missing. Using Runx3-ChIP-seq and transcriptome analysis of wild type vs. Runx3(-/-) primary cells we have now identified Runx3-regulated gene...
متن کاملTranscriptional regulation of the mu-delta heavy chain locus in normal murine B lymphocytes
The heavy chain genes for IgM (C mu) and IgD (C delta) are expressed differentially during B cell maturation and activation. We have determined the role that transcription plays in the regulation of these changes by using the method of in vitro nascent RNA chain elongation. In neonatal cells that express much lower densities of IgD than IgM on their surface, transcription of C delta is observed...
متن کاملTranscriptional activation of the human cytotoxic serine protease gene CSP-B in T lymphocytes.
The cytotoxic serine protease B (CSP-B) gene is activated during cytotoxic T-lymphocyte maturation. In this report, we demonstrate that the PEER T-cell line (bearing gamma/delta T-cell receptors) accumulates CSP-B mRNA following exposure to 12-O-tetradecanoylphorbol-13-acetate (TPA) and N6-2'-O-dibutyryladenosine 3',5'-cyclic monophosphate (bt2cAMP) because of transcriptional activation of the ...
متن کاملGenome-Wide Discovery of Modulators of Transcriptional Interactions in Human B Lymphocytes
Transcriptional interactions in a cell are modulated by a variety of mechanisms that prevent their representation as pure pairwise interactions between a transcription factor and its target(s). These include, among others, transcription factor activation by phosphorylation and acetylation, formation of active complexes with one or more cofactors, and mRNA/protein degradation and stabilization p...
