Title: Activation of mineralocorticoid agonist and antagonist specific receptors from rat kidney. Author: Agarwal MK, Kalimi M. Journal: Biochem Biophys Res Commun; 1987 Feb 27; 143(1):398-402. PubMed ID: 3030321. Abstract: The kinetics of saturation, as well as of denaturation, confirm the existence of two distinct mineralocorticoid receptor populations one each for the agonist aldosterone (MR2) and the antagonist RU 26752 (MR3) in rat kidney. Receptor activation in vitro was dependent upon the buffer, progressed just as well in the presence of the agonist and the antagonist, and was inhibited by molybdate. These necessitate a reassessment of both the importance of receptor activation in vitro and its possible contribution to hormone action in vivo.[Abstract] [Full Text] [Related] [New Search]
