(Submitter supplied) Precise control of mRNA decay is fundamental for robust yet not exaggerated inflammatory responses to pathogens. Parameters determining the specificity and extent of mRNA degradation within the entire inflammation-associated transcriptome remain incompletely understood. Using transcriptome-wide high resolution occupancy assessment of the mRNA-destabilizing protein TTP, a major inflammation-limiting factor, we qualitatively and quantitatively characterize TTP binding positions and functionally relate them to TTP-dependent mRNA decay in immunostimulated macrophages. more...

(Submitter supplied) Controlled decay of cytokine and chemokine mRNAs restrains the time and amplitude of inflammatory responses. Tristetraprolin (TTP) binds to AU-rich elements in 3´ untranslated regions of mRNA and targets the bound mRNA for degradation. We have addressed here the function of TTP in balancing the macrophage activation state by a comprehensive analysis of TTP-dependent mRNA decay in LPS-stimulated macrophages from WT and TTP-deficient mice.

(Submitter supplied) The mitogen-activated protein kinase (MAPK) p38 pathway is reported to regulate macrophage responses to lipopolysaccharide (LPS) at least partly via the phosphorylation of the mRNA-destabilizing factor tristetraprolin (TTP). LPS-activated MAPK p38 phosphorylates and activates the downstream kinase MAPK-activated protein kinase 2 (MK2), which then phosphorylates serines 52 and 178 of TTP, resulting in loss of mRNA-destabilizing activity. more...

(Submitter supplied) Tristetraprolin (TTP) is a tandem CCCH zinc finger protein that was identified through its rapid induction by mitogens in fibroblasts. Studies of TTP-deficient mice, and cells derived from them, showed that TTP could bind to certain AU-rich elements in mRNAs, leading to increases in the rates of mRNA deadenylation and destruction. Known physiological target mRNAs for TTP include tumor necrosis factor alpha (TNF), granulocyte macrophage colony stimulating factor (GM-CSF) and interleukin 2 beta (IL2 beta). more...

Analysis of tristetrapolin (TTP)-deficient fibroblasts after serum activation and subsequent actinomycin D treatment for up to 120 minutes. TTP is a tandem CCCH zinc finger protein that binds to AU-rich elements in mRNA, leading to increases in the rates of mRNA deadenylation and destruction.

(Submitter supplied) Tristetraprolin (TTP) binds to specific AU-rich elements in the 3'UTR of certain transcripts and regulates post-transcriptional gene expression by increasing the rate of mRNA turnover. In this study, we evaluated the effects of TTP deficiency on the overall gene expression of spleen tissue, in order to discover tissue specific targets of TTP under normal physiologic conditions. We utilized "Triple KO" (Zfp36-/-/TNFR1-/-/TNFR2-/-) mice that are deficient in TTP and two TNF receptors and compared the transcriptomic changes to "Double KO" (TNFR1-/-/TNFR2-/-) and WT mice. more...

(Submitter supplied) we cloned and overexpressed human TTP-encoding gene ZFP36 in HeLa cell in the absence of inflammatory stimuli. The transcriptomes of the control and ZFP36-overexpression cells were sequenced and subjected to analysis and validation. Upon ZFP36 overexpression, expression of genes in innate immunity, including those in type I interferon signaling pathway and viral response, were specifically up-regulated, implying a transcriptional regulatory mechanism associated with the predicted DNA binding activity of TTP. more...

(Submitter supplied) In many eukaryotes, mRNAs containing specific AU-rich motifs are regulated by proteins of the tristetraprolin (TTP) family, which bind to these motifs through a tandem zinc finger (TZF) domain. This binding leads to promotion of subsequent deadenylation and decay, partly through a conserved carboxyl-terminal CNOT1 binding domain. We explored the physiological role of the single TTP family member (TtpA) expressed in Dictyostelium discoideum. more...
