The senolytic drug ABT-263 accelerates ovarian aging in older female mice.

ABSTRACT: Previous studies have reported that senolytic drugs can reverse obesity-mediated accumulation of senescent cells in the ovary and protect against cisplatin-induced ovarian injury by removing senescent cells. Early intervention with ABT-263 has been shown to mitigate ovarian aging. However, it remains unknown whether treatment with ABT-263 could rejuvenate the aged ovary in reproductively old females. Therefore, the current study was aimed to investigate whether advanced age intervention with ABT-263 could ameliorate age-related decline in ovarian function. Fourteen 16-month-old mice with a C57/BL6 background were treated with ABT-263 (N = 7) or vehicle (N = 7) for two weeks. Mice were initially treated with ABT-263 (60 mg/kg/d) or vehicle for 7 consecutive days. After a 7-day break, the tr
