WebSubstantial evidence points to a critical role for the p300/CREB binding protein (CBP) coactivators in p53 responses to DNA damage. p300/CBP and the associated protein P/CAF bind to and acetylate p53 during the DNA damage response, and are needed for full p53 transactivation as well as downstream p5 …. 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).

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. … WebRepositorio. Portal de Datos Abiertos UNAM, Colecciones Universitarias. 2,045,979.

p53 inhibits hypoxia-inducible factor-stimulated transcription

WebApr 14, 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). WebThe two cancer-related transcription factors p53 and hypoxia-inducible factor (HIF)-1 are reported to interact either directly (1) or in a complex with the coactivator protein p300 (2). The interaction has been suggested to mediate hypoxia-induced apoptosis (3) and constitute a pathway of HIF-1 degradation (4) but is controversial (5).

WebJul 17, 2024 · The interaction of HIF-1α and p53 with the cofactor p300 is required for stable transcriptional activation. We found that TGase 2-mediated p53 depletion increased the availability of p300 for HIF-1α-p300 binding. A preclinical xenograft model suggested that TGase 2 inhibition can reverse angiogenesis in RCC. WebHypoxia-inducible factor 1α (HIF-1α) and p53 are pivotal regulators of tumor growth. Lysophosphatidic acid (LPA) is a lipid mediator that functions as a mitogen by acting through LPA receptors. We have shown previously that LPA stimulates HIF-1α expression in colon cancer cells.

WebOct 10, 2024 · Under hypoxia, HIF-1α-hydroxylase and PHDs are inactive leading to HIF-1α accumulation, nuclear translocation followed by HIF-1β and p300 bindings with the final outcome of HIF-1α stabilization and transcriptional activation.
