Y disease (pkd) is a group of diseases caused by mutations in single genes and is characterized by enlarged kidneys due to the formation of multiple cysts in both kidneys. Tubule cells proliferate, causing segmental dilation, in association with the abnormal deposition of several proteins. buy viagra cheap One of the first abnormalities described in cell biological studies of pkd pathogenesis was the abnormal mislocalization of the egfr in cyst lining epithelial cells. The kidney collecting duct (cd) is predominantly an absorptive epithelium where electrogenic na^+ entry is mediated by the epithelial na^+ channel (enac). Enac-mediated sodium absorption represents an important ion transport pathway in the cd that might be involved in the development of pkd. A role for egf in the regulation of enac-mediated sodium absorption has been proposed. However, several investigations have reported contradictory results indicating opposite effects of egf and its related factors on enac activity and sodium transport. Recent advances in understanding how proteins in the egf family regulate the proliferation and sodium transport in normal and pkd epithelial cells are discussed here.
