Ion transport in the renal proximal tubule (RPT) is regulated by numerous hormones and humoral factors, including insulin and dopamine. Previous studies show an interaction between insulin and the D(1) receptor. Because both D(1) and D(5) receptors belong to the D(1)-like receptor subfamily, it is possible that an interaction between insulin and the D(5) dopamine receptor exists in RPT cells from normotensive Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHRs).
