Dynamics of Serum Exosome microRNA Profile Altered by Chemically Induced Estropause and Rescued by Estrogen Therapy in Female Mice
The decline in the ovarian reserve leads to menopause and reduced serum estrogens. MicroRNAs are small non-coding RNAs, which can regulate gene expression, and be secreted by cells and trafficked in serum via exosomes. Serum miRNAs regulate tissue function and disease development. Therefore, the aim of this study was to identify miRNA profiles in serum exosomes of mice induced to estropause and treated with 17-beta-estradiol (E2). Female mice were divided into three groups including control (CTL), injected with 4-Vinylcyclohexene diepoxide (VCD) and injected with VCD plus E2 (VCD+E2).
