This study investigated the ET(A) and ET(B) receptor subtypes in rat adrenal cortex. The ET(A) antagonist, BQ-123, inhibited the zona glomerulosa (zg), but not the inner zone (iz) response to ET-1. RES-701-1, the ET(B) antagonist, abolished the iz response to ET-1, but had less effect on the zg. [125I]ET-1 binding studies revealed two receptor subtypes in both zones, with ET(A) predominating in the zg, and ET(B) in the iz. These data suggest that the ET(A) subtype is functionally more important… CONTINUE READING
