In our study, we demonstrate that ccRCC cell lines with impaired function of pVHL to degrade HiF alpha express elevated levels of PD-L1. in vitro analysis provided evidence that both reconstitution of pVHL and silencing of HIF2 alpha, but not of HIF1 alpha, lead to reduced PD-L1 expression. The strong correlation of expression between the HIF2 alpha-specific HIF target Glut1 and PD-L1 confirmed this finding in ccRCC cell lines and tissue. Soluble PD-L1 levels remained constant in the sera of ccRCC patients regardless of the PD-L1 expression status in their tumors. In conclusion, our data suggest PD-L1 as HIF2 alpha target, which is upregulated in pVHL deficient ccRCC. The combination of PD-L1 targeting drugs with HIF inhibiting agents may be an addittonal op ion for the treatment of ccRCC.
