Web1 de jun. de 2010 · In summary, we demonstrated that HNF4α plays a key role in transcriptional regulation of CTRP5. Considering that CTRP5 is involved in glucose and fatty acid metabolism, our work identifying HNF4α as a cis-acting element for CTRP5 regulation helps elucidate the regulatory mechanism of CTRP5 in metabolic diseases … Web14 de abr. de 2024 · The hypoxia therapy results in recruitment of the transcriptional coactivator p300, an increase in HIF 1 association, and the basal transcriptional machinery components RNA polymerase II and TFIIB. Under hypoxia, this transcriptional complex is still linked to the gene and is also linked to exon 12 of the hTERT gene, which is located …

Web3 de ago. de 2024 · Factor-inhibiting HIF-1 (FIH1) and reactive oxygen species (ROS) can also affect HIF-1α stability. The former hydroxylates an asparagine residue (Asn803) of HIF-1α in the C-terminal transactivation domain, thereby blocking HIF binding to the transcriptional coactivator cAMP response element-binding protein (CBP)/p300 and … Webthe previously reported negative regulation of wt p53 on HIF-1 α stability, depletion of wt p53 increased normoxic levels of HIF-1 α (SI Appendix,Fig.S2E). These last results were in agreement with previous studies, reporting the hypoxia-dependent stabilization of wt p53 (19, 20), a negative regulation of HIF-1 α stability following
