Web9 de abr. de 2024 · Mutant KRAS increased the production of reactive oxygen species, an inhibitor of prolyl hydroxylase activity which decreases HIF-1α hydroxylation, leading to enhanced HIF-1α stabilization. WebMutations in the EPAS1 gene change single protein building blocks (amino acids) in the HIF-2α protein. These changes prevent HIF-2α from interacting normally with the proteins that target it for degradation. As a result, HIF-2α is not degraded efficiently, and HIF accumulates in cells even when adequate oxygen is available.
