While activation of HIF-1α decreases intestinal inflammation and is beneficial in colitis, activation of HIF-2α exacerbates colitis and increases colon carcinogenesis in animal models, primarily due to the role of epithelial HIF-2α in mounting a potent inflammatory response.

Moreover, we found that (i) stabilization of HIF-1α and HIF-2α, which are involved in mediation of the hypoxic responses in the majority of cell types, (ii) up-regulation of MYCC, a key onco-protein whose dysregulation occurs in ~70% of human tumors, and (iii) accumulation of stabilized p53, which is commonly altered in human cancers, constitute hallmarks of our tumor model, and might represent the basis for CNS-PNET tumorigenesis in this model.

The main aim of this perspective is to address the possibility of HIF-2α antagonists in the management of tumours, beyond clear cell renal cell carcinoma, where the dysfunctional hypoxia-signalling pathway, especially HIF-2α, referred here as the Achilles' heel, plays a unique role in tumorigenesis and other disorders.
