Somatostatin (SRIF), the somatotropin release inhibiting factor of the hypothalamus, has been reported to inhibit the production of angiotensin II (AII)-stimulated aldosterone in the rat adrenal glomerulosa cells. Since the interrenal of the frog is the homolog of mammalian adrenal zona glomerulosa, the effect of synthetic SRIF on perifused dice of Rana ridibunda was tested. Graded doses of SRIF did not modify the spontaneous production of corticosterone and aldosterone. The highest concentration of SRIF (10(-5) M) did not alter the stimulatory effect of the AII agonist [Sar1-Val5] AII upon corticosteroidogenesis. Thus, in apparent contradiction to recent findings in mammals, SRIF did not alter the effect of AII in the frog interrenal cell.

D013004 Somatostatin A 14-amino acid peptide named for its ability to inhibit pituitary GROWTH HORMONE release, also called somatotropin release-inhibiting factor. It is expressed in the central and peripheral nervous systems, the gut, and other organs. SRIF can also inhibit the release of THYROID-STIMULATING HORMONE; PROLACTIN; INSULIN; and GLUCAGON besides acting as a neurotransmitter and neuromodulator. In a number of species including humans, there is an additional form of somatostatin, SRIF-28 with a 14-amino acid extension at the N-terminal.
