REGULATION OF FIH EXPRESSION IN RENAL CANCER:
Hydroxylation at an asparagine residue at the C-terminal activation domain of hypoxia inducible factor-1/2 a s (HIF a ) is essential for its inactivation under normoxic condition. To date, the mechanism by which HIF a avoids the inhibitory effect of asparagine hydroxylase in renal cell carcinoma (RCC) in normoxia is undefined. We have shown herein that protein kinase C zeta (PKC z ) has an important role in HIF a activation in RCC.
