Abstract

Two of the agents known to block the renin-angiotensin-aldosterone system, namely Sar1-Ala8-angiotensin II and the nonapeptide SQ 20881, have been used to clarify the role of angiotensin II (AII) and its cogeners upon the steroidogenesis in isolated fasciculata cells from bovine adrenal tissue. It could be concluded that: (1) des-Asp1-angiotensin II is as active as AII on steroidogenesis from bovine fasciculata cells; (2) angiotensin I, although less potent, stimulates steroid production without being converted to AII or des-Asp1-AII, and (3) Sar1-Ala8-AII inhibits all three peptides in a competitive manner. The presence of a common receptor for all these three peptides is suggested.
