WebApr 14, 2024 · Initially, HIF-1a accumulates under mild hypoxic conditions because of decrease in enzymatic activities of PHD, which has markedly high Km values than FIH. Under severely hypoxic conditions, it then shows its maximum transcriptional activity by interacting with p300/CBP as a result of inactivation of HIF-1α (Koivunen et al. 2004). WebSep 8, 2015 · In anoxia, p53 competitively binds to p300 and Mdm2 targets HIF-1α for degradation; thus, the HIF-1α ac level drops markedly and rather low levels of p21 are induced. These results are...
WebMay 5, 2006 · von Hippel-Lindau (VHL) disease is a rare autosomal dominant cancer syndrome. Although hypoxia-inducible factor-α (HIFα) is a well-documented substrate of von Hippel-Lindau tumor suppressor protein (pVHL), it remains unclear whether the dysregulation of HIF is sufficient to account for de novo tumorigenesis in VHL-deleted … WebMay 15, 1998 · p53 is required for hypoxia-induced apoptosis in vivo, although the mechanism by which this occurs is not known. Conversely, induction of the hypoxia-inducible factor-1 (HIF-1) transactivator stimulates transcription of a number of genes crucial to survival of the hypoxic state.
WebJul 7, 2024 · Apart from HIF-1α, p53 is also activated during hypoxia exposure and … WebInterestingly, the HDAI-mediated repression of transactivation potential distinguishes HIF- α from other p300/CBP-dependent TFs. We notice that p53 and MyoD are involved in growth arrest and...
Webp53 is required for hypoxia-induced apoptosisin vivo, although the mechanism by which this occurs is not known. Conversely, induction of the hypoxia-inducible factor-1 (HIF-1) transactivator stimulates transcription of a number of genes crucial to survival of the hypoxic state. Here we demonstrate that p53 represses HIF-1-stimulated transcription. …
WebSep 2, 2016 · This fits our modeling of the p53-p300 interaction via TAD2 indicating a potentially weaker binding in Spalax relative to humans. Importantly, under hypoxia, p53 crosstalks with the hypoxic response transcription factor hypoxia inducible factor 1 (HIF-1) and both compete for p300 as a co-activator to enhance transcription of their target genes . fukushima nuclear power plant damageWebAug 1, 2024 · HIF-1α activity is mainly regulated by its transcriptional co-activator p300 which has histone acetyl-transferase (HAT) activity. p300 HAT activity is very crucial for p300 auto-acetylation and subsequently its interaction with its partner molecule HIF-1α as well as proapoptotic protein p53. p300 is a multi-domain protein and CH1 domain of ... fukushima nuclear power plant cleanupWebOct 2, 2008 · As the K320 p53 acetylation is the site predominantly affected in hypoxia, the PCAF histone acetyltransferase activity is the key regulator of the cellular fate modulated by p53 under these conditions.
