Hif p53
WebCancer cells must acquire a greater amount of nutrients, especially glucose. One of the mediators is HIF-1, which increases glucose uptake through the induction of GLUT-1, GLUT-4 and GLUT-1; simultaneosly, it can also be stimulated by TGF-β through the PI3K/AKT/mTOR pathway. Other important mediators are p53 that plays a protective role ... Web31 de out. de 2024 · In particular, while HIF-1α recruits and shuttles mutant p53 to the DNA genomic elements, mutant p53 does not influence HIF-1 binding to the DNA but impinges on its transcriptional activity. The binding of mutant p53 to the genomic elements is, however, not completely abolished by HIF-1α depletion, indicating that other factors also …

Web28 de jul. de 2024 · In mild hypoxia, HIF-1 has a rather protective effect due to the induced expressions of various anti-apoptotic proteins. In contrast, severe hypoxia (anoxia) leads to cell death, which is at least partly caused by HIF-1α-mediated p53 stabilization (Levine, 1997; Suzuki et al., 2001). Role of HIF-1α in Neurodegenerative Diseases Alzheimer’s ... WebHIF-1 signaling stimulates angiogenesis and mediates cellular adaptation to hypoxia, whereas p53 promotes hypoxia-induced apoptosis. A recent article provides in vitro …
Web28 de jul. de 2024 · We propose that VHL has both anti-tumor function, via HIF degradation, and a new pro-tumor function via p53 target (p21, PUMA, Bax) inhibition. Because p53 plays a critical role in tumor biology, is activated by many chemotherapies, and because VHL levels vary among different tumors and its function can even be lost by … Web30 de nov. de 2024 · Pulmonary fibrosis is a progressively aggravating lethal disease that is a serious public health concern.
