Web29 de out. de 1999 · HIF-1 is a heterodimeric complex composed of two subunits belonging to the Per-aryl hydrocarbon nuclear translocator (ARNT)-Sim (PAS)-basic helix loop helix (bHLH) family, HIF-1α and ARNT [2], [3]. The mechanism of hypoxia-dependent function and activation of the HIF-1α-ARNT complex is currently poorly understood.
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]. mahogany shower benchWebHere, we gather and discuss the evidence on the non-canonical HIF-1α regulation, focusing in particular on the consequences of mitochondrial respiratory complexes damage on stabilization of this pleiotropic transcription factor.
