Recent data indicate that … Web15 de jun. de 2024 · HIF1 and HIF2 differential interactions with two central growth-promoting drivers, MYC and mTORC1, provide key explanations for at least some of the functional contrasts between the isoforms. In brief, hypoxic induction of HIF1 prevents MYC from associating with its partner MAX and with SP1 transcription factor on chromatin; the …
Web14 de jun. de 2016 · Furthermore, HIF1A expression showed progressive induction in breast tumors from grade 1 to grade 3, and HIF2A (EPAS1) expression showed the opposite (Fig. 1B); this result is consistent with the antagonistic relationship between HIF1-α and HIF2-α reported previously in breast cancer . WebHIF1 and HIF2 activate transcription of a broad range of target genes (e.g., vascular endothelial growth factor [VEGF]) with some overlap between the two factors.4 Numerous other pathways have been implicated in posttranslational HIF regulation and have been reviewed elsewhere.5 A simplified version of posttransla-
