(Submitter supplied) Gene regulation by cytokine-activated STAT transcription factors requires serine phosphorylation within the transactivation domain (TAD). STAT1 and STAT3 TAD phosphorylation was reported to occur upon promoter binding by an unknown kinase. Here we show that the Mediator CDK8 module phosphorylates S727 of the STAT1 TAD in the interferon (IFN) signaling pathway as well as the TADs of other STATs. Microarray analysis reveals that CDK8-mediated STAT1 TAD phosphorylation positively or negatively regulates over 40% of IFN-gamma-responsive genes, and RNA polymerase II occupancy correlates with gene expression changes. more...

(Submitter supplied) Cytokines are highly pleiotropic ligands that critically contribute to a balanced immune response. We have an incomplete understanding of how cytokines elicit their functional pleiotropy, which has limited their therapeutic use. Here, using Interleukin-6 (IL-6) as a model system, we have performed detailed phosphoproteomic and transcriptomic studies in human Th-1 cells to address the molecular bases defining cytokine functional pleiotropy. more...

(Submitter supplied) IFNg is a pro-inflammatory and pro-atherogenic cytokine that leads to macrophage activation. Adenosine has well-documented anti-inflammatory properties. We used microarrays to compare the global gene expression profile in mouse macrophages stimulated with IFNg alone and those cells treated with IFNg and adenosine. We determined that adenosine suppressed the expression of many IFNg-regulated pro-inflammatory cytokines, chemokines, and other pro-atherogenic genes. more...

(Submitter supplied) Compared to primary human monocytes in whole blood cultures, few B cells activated STAT1 in response to stimulation of 2000 IU/ml IFN-beta for 45 minutes. Because activation of STAT1 leads to apoptosis induction, we tested the hypothesis that less pro-apoptotic genes are induced in B cells as compared to monocytes. Manuscript titled: Major differences in the responses of primary human leukocyte subsets to IFN-beta. more...

(Submitter supplied) Atherosclerosis is a disease of large and medium-sized muscular arteries and is characterized by vascular inflammation and lipid-laden plaque formation within the intima of the vessel wall. Atherosclerosis is initiated by recruitment of blood leukocytes to the injured vascular endothelium and leads to altered contractility of Vascular Smooth Muscle Cells (VSMCs), acute and chronic luminal obstruction, abnormalities of blood flow and diminished oxygen supply to target organs. more...

(Submitter supplied) We characterized the marine natural product cortistatin A (CA) as an inhibitor of CDK8 to determine whether pharmacologic inhibition of CDK8 regulates super-enhancer function and inhibits AML proliferation. In this series, we use ChIP-seq of STAT1 and STAT1 pS727 to examine how the localization of STAT1 is affected by inhibition of serine 727 phosphorylation

(Submitter supplied) Complete activation of macrophage proinflammatory and antimicrobial phenotype is promoted by combined action of IFN-g and LPS. Synergistic activation of canonical inflammatory NF-kB target genes by IFN-g and LPS is well appreciated, but less is known about whether IFN-g negatively regulates components of the LPS response, and how this affects polarization. A combined transcriptomic and epigenomic approach revealed that IFN-g selectively abrogates LPS-induced feedback and select metabolic pathways by suppressing TLR4-mediated activation of gene enhancers. more...

(Submitter supplied) Virus infection induces the production of type I and type II interferons (IFN-I and IFN-II), cytokines that mediate the antiviral response. IFN-I (IFN-a and -b) induces the assembly of ISGF3 (interferon-stimulated gene factor 3), a multimeric transcriptional activation complex comprised of STAT1, STAT2 and IRF9. IFN-II (IFN-g) induces the homodimerization of STAT1 to form the GAF (gamma-activated factor) complex. more...

(Submitter supplied) Pluripotent stem cells (PSCs) can transition between cell states in vitro, closely reflecting developmental changes in the early embryo. PSCs can be stabilized in their naive state by blocking extracellular differentiation stimuli, particularly FGF5 MEK signaling. Here, we report that multiple features of the naive state in human and mouse PSCs can be recapitulated without affecting FGF-MEK-signaling. more...
