Hif1 regulation
Web27 de out. de 2024 · Besides the regulation of OXPHOS genes, HIF-1 may be affected by many other factors, including hormones, growth factors and cytokines etc. on transcriptional and post-transcriptional level . Increasing studies have elucidated that HIF genes could be regulated in the NF-κB (nuclear factor kappa-B) dependent manner. WebThe hypoxia-inducible factor-1 (HIF-1) is the master regulator of the cellular response to hypoxia and its expression levels are tightly controlled through synthesis and degradation. It is widely accepted that HIF-1α protein accumulation during hypoxia results from inhibition of its oxygen-dependent degradation by the von Hippel Lindau protein (pVHL) pathway. …
