Background: Both, increased plasma concentrations of vascular endothelial growth factor (VEGF) and increased expression of transient receptor potential canonical type 6 (TRPC6) channels in podocytes have been associated with proteinuric kidney diseases. Now, we investigated the hypothesis that VEGF regulates TRPC6 in podocytes.
Methods: TRPC6 messenger RNA (mRNA) and TRPC6 protein expression were analyzed in cultured podocytes after administration of VEGF165 using quantitative real-time reverse transcription-polymerase chain reaction and immunoblotting, respectively.
