WebLoss of pVHL leads the inappropriate accumulation of active HIF1 and HIF2. HIF2 drives clear cell renal carcinogenesis, and drugs that inhibit the HIF2-responsive gene product VEGF are now cornerstones of kidney cancer therapy. WebHIF is composed of a constitutively expressed HIF1-β subunit and oxygen-sensitive HIF1-α or HIF2-α subunits ( 6). Under aerobic conditions, the HIF-α subunits are hydroxylated ( 7) at the level of conserved proline and asparagine residues.
