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

Recently, it has been shown that brain topical superfusion of endothelin (ET)-1 at concentrations around 100 nM induces repetitive cortical spreading depressions (CSDs) in vivo. It has remained unclear whether this effect of ET-1 is related to a primary neuronal/astroglial

The involvement of endothelin receptors in the contraction of the lower urinary tract smooth muscle is well established. There is scarce information, however, about endothelin receptors mediating relaxation of the bladder outlet region. The current study investigates the possible existence
Ana Sánchez et al.
European journal of pharmacology, 640(1-3), 190-196 (2010-05-25)
Since endothelin-1 (ET-1) is involved in prostatic disorders, the current study investigated the mechanisms underlying the ET-1-induced effects in pig prostatic small arteries. The experiments were performed in rings mounted in microvascular myographs containing physiological saline solution at 37oC for
