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.

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). 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.
