| الوصف: | Polycystic ovary syndrome (PCOS) is a condition resulting from the interaction between environmental factors and hereditary components, profoundly affecting offspring development. Although the etiology of this disease remains unclear, aberrant in utero androgen exposure is considered one of the pivotal pathogenic factors. Herein, we demonstrate the intergenerational inheritance of PCOS-like phenotypes in F2 female offspring through F1 males caused by maternal testosterone exposure in F0 mice. We found impaired serum hormone expression and reproductive system development in prenatal testosterone-treated F1 male and F2 female mice (PTF1 and PTF2). In addition, downregulated N6-methyladenosine (m6A) methyltransferase and binding proteins induced mRNA hypomethylation in the PTF1 testis, including frizzled-6 (Fzd6). In the PTF2 ovary, decreased FZD6 protein expression inhibited the mammalian target of rapamycin (mTOR) signaling pathway and activated Forkhead box O3 (FoxO3) phosphorylation, which led to impaired follicular development. These data indicate that epigenetic modification of the mTOR signaling pathway could be involved in the intergenerational inheritance of maternal testosterone exposure-induced impairments in the PTF2 ovary through male PTF1 mice. |
