Abstract (summary): Renal cell carcinoma (RCC) is the commonest urogenital tumor, characterized by increased expression of hypoxia inducible factors (HIFs). During normoxia, HIFα subunits are targeted for proteasomal degradation by the product of the von Hippel Lindau gene (pVHL). In RCC, mutations in the VHL gene allow the HIFα subunits to escape degradation and translocate to the nucleus where they activate transcription of their target genes. Although both HIF1α and HIF2α are upregulated in RCC, it has been suggested that HIF2α plays the dominant role. To further elucidate the function of HIF2α in RCC, we generated a transgenic mouse model that permits temporal stabilization of HIF2α in renal tubular cells. Induction of HIF2α results in the rapid development of renal cysts - a feature observed in RCC. Taken together, these results suggest that HIF2α is a key player in development of RCC and an excellent candidate target for therapy in this disorder.
