The role of dietary potassium in regulating miRNA-802 and CAV1 expression in the kidney. A diet high in potassium results in up-regulation of miRNA-802 which down-regulates CAV1’s expression by binding to 3′UTR of CAV1. Interaction of CAV1 with the N-terminus of the ROMK channels down-regulates these ion channels in the distal nephron, down-regulation of CAV1 results in up-regulation of the ROMK channels
