Web10 de out. de 2024 · HIF 1 could either binds to NOX2 or upregulates Nox4-dependent ROS formation (Diebold et al., 2010, 2012). In agreement hypoxia has been shown to upregulate Nox2 mRNA expression in brain cortex and stem in wild type (WT) mice but not in HIF2 heterozygous mice ( Yuan et al., 2011 ) suggesting a HIF1, and not HIF2, dependence. WebRecent studies suggest that induction of NOX4 by HIF1-alpha contributes to maintain ROS levels after hypoxia and hypoxia-induced proliferation. In humans, it is located on the q arm of chromosome 14. The C-terminal of HIF1A binds to p300. p300/CBP-HIF complexes participate in the induction of hypoxia-responsive genes, including VEGF.
