Web11 de jun. de 2014 · Introduction. Hypoxia inducible factor-1α (HIF1α), its orthologue HIF2α, and their dimerization partner the aryl hydrocarbon receptor nuclear translocator, (ARNT or HIF1β) which make up the HIF1 complex , regulates a cell’s response to conditions of low oxygen. In healthy tissue, the HIF1 complex directs the ordered and tightly regulated … WebIn summary, AhR recruits Rb as a co-activator, while Rb negatively regulates HIF1 activity and presumably might dampen AhR activity by virtue of its association with the ARNT-TRIP230 complex [197].
