Abstract
Premature ovarian insufficiency (POI) may lead to early menopause, fertility loss and birth defects without effective treatment. Here, we explored the efficacy and safety of gene therapy to rescue ovarian function in both natural ovarian aging and doxorubicin (Dox) induced POI mice. Sirt1 and Tgfbr2 were screened out and identified as key genes in both murine and human ovarian tissues. Then, adenovirus (AdV) was selected as a suited carrier for ovarian infection after comparison of multiple viral vectors. In both two models, murine fertility was significantly improved after AdV-Sirt1 and AdV-Tgfbr2 invention individually or in combination, without obvious side effects to themselves and their offspring. Compared with the control group, the successful pregnancy rate in the 9-month-old-AdV-Sirt1 group increased by 60 % (67 % vs 42 %). Meanwhile, the pregnancy rate in the AdV-Tgfbr2 + Dox group increased by 85 % (55.6 % vs 20 %). The biological process of ovarian follicle development and fibrosis was rescued. Our work demonstrated that AdV-Sirt1 and AdV-Tgfbr2 therapy alleviates natural ovarian aging and Dox-associated POI, which may be potentially applicable for female fertility protection.
