Web1 de jul. de 2024 · 2, HIF is not hydroxylated and stabilized. Two transcriptionally active HIFs have been identified, HIF-1a and endothelial PAS domain protein 1 (EPAS1, also referred to as HIF-2a). They share a 48% sequence identity and regulate over-lapping and distinct sets of genes critical in the adaptation to hypoxic environments. Web25 de mai. de 2024 · 5003 Background: Patients (pts) with Von Hippel-Lindau disease (VHL) are at risk for several cancers, including clear cell renal cell carcinoma (ccRCC). Inactivation of VHL results in constitutive activation of the HIF-2α transcription factor, which drives tumor growth. MK-6482, a potent, selective, small molecule HIF-2α inhibitor, has shown …
