Web5 de abr. de 2001 · Hypoxia-inducible factor (HIF) is a transcriptional complex that plays a central role in the regulation of gene expression by oxygen. In oxygenated and iron replete cells, HIF-α subunits are rapidly destroyed by a mechanism that involves ubiquitylation by the von Hippel–Lindau tumor suppressor (pVHL) E3 ligase complex. Web14 de fev. de 2024 · Independently, the presence of this mutation likely explains the persistence of HIF-2 complexes and preserved HIF-2 target gene expression despite PT2385 treatment (Fig. 2A and B). Overall, these data show that rapid acquisition of resistance may not always indicate target-independent biology and raises the possibility …
