Abstract

The possible involvement of a cAMP pathway in endothelin (ET) signal transduction was explored using rat atrial slices. We show that ET-1 induces both stimulation and inhibition of cAMP formation, depending onits concentration. Unexpectedly, the effects of ET-3 and of sarafotoxins b and c (SRTX-b and SRTX-c) on this pathway differ from that of ET-1. Moreover, we show that the ET-1-induced formation of cAMP results from catecholamine release in a process mediated by a Ca2+ channel coupled to a pertussis toxin sensitive G-protein. It is concluded that this pathway is mediated by a new ET(A) receptor subtype (probably presynaptic), for which ET-1 is an agonist and ET-3, SRTX-b, and SRTX-c areantagonists.
