Outline of Final Research Achievements

Cancer treatment including chemotherapy induces ovarian toxicity such as infertility and the early menopause. At this stage, there is no treatment or prevention against ovarian toxicity. In this study, we focus on the microenvironment in the ovary, and explored the mechanism of chemotherapy-induced premature ovarian insufficiency (POI). We established the chemotherapy induced premature ovarian insufficiency mouse models. We showed that the protein expression of cellular senescence markers were increased in the ovary of POI model. It suggested that the treatment of senolytic drug can be a good candidate for the treatment or prevention of chemotherapy-induced ovarian toxicity.

Academic Significance and Societal Importance of the Research Achievements

近年、癌治療の発展及び生殖医療の進歩に伴い、小児、思春期・若年成人のがんサバイバーに対する生活の質に対して注目が集まっている。がん治療に伴う卵巣毒性によって、妊孕性の損失だけでなく、早発閉経に伴う晩期障害により長期的な影響を受ける。現時点ではがん治療に対する卵巣毒性を軽減する方法はなく、卵巣毒性に対する分子生物学的メカニズムが完全には解明されていない。本研究によって、抗がん剤投与による卵巣毒性に細胞老化が関連していることが示唆され、老化細胞を除去するセノリティクス薬を投与することにより、抗がん剤投与に伴う早発卵巣機能不全を予防する新たな治療戦略となることが期待される。
