Evidence has been provided that the 21-amino acid hypertensive peptide endothelin (ET)-1 exerts a potent secretagogue effect on human adrenocortical zona glomerulosa (ZG), acting through two receptor subtypes, called ET(A) and ET(B), the signaling mechanism(s) of which has (have) not

The physiological properties of endothelin-1 in ocular choroidal melanocytes are not well-known, although endothelin-1 increases the intracellular calcium concentration through endothelin-B receptors in skin melanocytes. We studied the effect of endothelin-1 on choroidal melanocytes in rabbit ocular suprachoroidal tissue. Fura-2
