1 Both GPER and membrane oestrogen receptor-alpha activation protect ventricular remodelling in 17beta oestradiol-treated ovariectomized infarcted rats. Estradiol G protein-coupled estrogen receptor 1 Rattus norvegicus
2 The phosphorylation of Akt and eNOS was significantly decreased in infarcted rats and restored by oestradiol and G-1, implying the GPER pathway in this process. Estradiol G protein-coupled estrogen receptor 1 Rattus norvegicus
3 Oestradiol-induced Akt phosphorylation was not abrogated by G-15 (a GPER blocker). Estradiol G protein-coupled estrogen receptor 1 Rattus norvegicus
4 These data support the conclusions that oestradiol improves ventricular remodelling by both GPER- and membrane-bound ERalpha-dependent mechanisms that converge into the PI3K/Akt/eNOS pathway, unveiling a novel mechanism by which oestradiol regulates pathological cardiomyocyte growth after infarction. Estradiol G protein-coupled estrogen receptor 1 Rattus norvegicus
