WebWhen cells were cultured in the absence of IL-3, Hif-1α mRNA decreased over time and growth factor-deprived cultures failed to increase Hif-1α mRNA levels when exposed to … WebThe regulation of HIF-1 is a complex process and involves a number of molecules and pathways. Among these mechanisms a direct regulatory role of reactive oxygen species (ROS) on HIF-1 alpha subunit has received a great deal of attention and the existing body of literature includes many contradictory findings.
WebRegulation of HIF-1α stability can also be mediated by an oxygen-independent pathway. In the cytoplasm, HIF-1α is bound to heat-shock protein 90 (Hsp90), leading to enhanced … 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. …
