GPER1 and metabolic syndrome: We replicated a mouse model of dyslipidemia and postmenopausal status in LDLR−/− mice and treated them with β-estradiol or simvastatin, and found that ovariectomy in LDLR−/− mice led to an exacerbation of dyslipidemia and increased hippocampal apoptosis and cognitive impairment, which were associated with reduced estradiol levels and ERα, ERβ and GPER expression.
