Research Abstract |
We studied the physiological function of Na^+/Ca^<2+> exchanger (NCX) in epithelial cells (renal tubular epithelium, vascular endothelium) and its pathological role, using genetically altered mice and NCX inhibitors. Suppression of NCX1 function (induced by heterozygous or isoform-specific inhibitor) mitigated the renal tubular injury after renal ischemic-reperfusion, whereas suppression of NCX2 function deteriorated the renal tubular injury. We also screened the protein associated with the intracellular domain of NCX1 (as a bait) by using yeast two-hybrid system, and then identified the new adapter protein (scaffold protein) bound to NCX1.
