Web25 de ago. de 2024 · p53 1. Introduction Evading apoptosis is one of the major characteristics of tumor cells. Hypoxia plays an important role in this process. Rapidly growing tumor cells easily become hypoxic due to the inability of the vascular system to provide an adequate amount of oxygen. WebOne study on epithelial ovarian cancer shows HIF1A and nonfunctional tumor suppressor p53 is correlated with low levels of tumor cell apoptosis and poor prognosis. [72] Further, early-stage esophageal cancer patients with demonstrated overexpression of HIF1 and absence of BCL2 expression also failed photodynamic therapy. [81]

WebHIF1 has a key role in cellular response to hypoxia, including the regulation of genes involved in energy metabolism, angiogenesis, and apoptosis. The alpha subunits of HIF are rapidly degraded by the proteasome under normal conditions but are stabilized by hypoxia. WebHIF1 appears to enhance p53 activation by -radiation (IR), resulting in increased p53 phosphorylation and p53-induced apoptosis (13). Furthermore, HIF1 has been shown to …
Web10 de nov. de 2024 · USP7 knockout has been shown to be lethal in mice, even in the absence of p53 [14], [15]. To function selectively, USP7 requires careful regulation of activity. A first layer of regulation is intrinsic in USP7's multidomain architecture; USP7 requires its C-terminal region for full activity, as the catalytic domain (CD) is 120-fold less … Web15 de fev. de 2008 · HIF-1 α controls metabolic and pH-regulating pathways.
