Web13 de abr. de 2024 · To date, colorectal cancer is still ranking top three cancer types severely threatening lives. According to cancer stem cell hypothesis, malignant colorectal lumps are cultivated by a set of abnormal epithelial cells with stem cell-like characteristics. These vicious stem cells are derived from intestinal epithelial stem cells or transformed … 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.
