WebEstrogen exerts divergent actions on vascular cells; namely it increases endothelial cell and inhibits smooth muscle cell growth, resulting in a vasoprotective action. We particularly focused on these divergent effects and examined the mechanisms. The effects of raloxifene, which shows estrogen-like vasoprotective actions, were also examined. Web31 de jan. de 2024 · Molecular mechanism of estrogen receptor action. The typical mechanism involves estrogen binding to the ligand-binding domain of receptors in the nucleus, which results in a conformational change. Then, the ligand-ER complexes dimerize and bind to estrogen-responsive elements (EREs) located in the promoters of target genes.

Progesterone has been established as an obligatory steroid mediator of pregnancy ( Corner, 1947; Reynolds, 1949; Reel et al., 1969). The primary physiologic effect of progesterone appears to be the induced transformation of uterine endometrial cells so that implantation of the developing blastocyst is facilitated.
