WebHypoxia-inducible factor-1 (HIF-1), a heterodimeric (containing α and β subunits) transcription factor, is involved in hypoxia response pathway that regulates the expression of many tumorrelated genes. The stabilized HIF-1 heterodimer couples to the general co-activators p300/CBP (CREB binding protein), forming an active transcription factor to … Web25 de fev. de 2024 · Throughout this pathway, the factor-inhibiting HIF-1 α is a negative regulator of HIF-1 α leading to its hydroxylation at the C-TAD domain of HIF-1 α under normoxia. Thus, hydroxylated HIF-1 α is unable to proceed with the transcriptional events due to interference in binding of C-TAD and CBP/p300. Web19 de mar. de 2002 · 1L8C. PubMed Abstract: The cellular response to low tissue oxygen concentrations is mediated by the hypoxia-inducible transcription factor HIF-1.

Web14 de abr. de 2024 · Interestingly, it has been shown that the tumor suppressor P53 binds to p300 and interferes with the interactions between p300 and HIF-1α, leading to the inhibition of HIF-1α and the induction of death in cells under severe hypoxic conditions. However, HIF-1α dissociates p300 from P53 in cells under mild hypoxic conditions (Ye et al. 2024). Web11 de abr. de 2024 · Under hypoxic conditions, HIF-2α is stabilized and interacts with HIF-β to form a heterodimer, which can bind to the functional hypoxia-response elements (HREs) in the ATX promoter and recruit p300/CBP to the ATX promoter. p300/CBP-mediated histone crotonylation induces ATX expression, leading to the elevation of extracellular …

Web13 de nov. de 2002 · Full HIF induction requires the interaction of the C-terminal transactivation domain (CTAD) with coactivators such as CBP/p300 to recruit the transcriptional machinery . Under normoxic conditions, this interaction is inhibited by hydroxylation of an asparagine residue within the CTAD by factor-inhibiting HIF-1 (FIH … WebIn addition, HIF-α undergoes asparaginyl hydroxylation by factor inhibiting HIF-1 (FIH) under non-hypoxic conditions, which prevents binding of HIF-α to the co-activators p300/CBP. Under hypoxia, PHD and FIH activity is substrate limited, resulting in rapid HIF-α accumulation, nuclear translocation and dimerization with HIF-1β.
