高齢出産特有遺伝子?

A team from Israel's Hadassah University Hospital believe the discovery could help improve fertility treatment for older women. They told a major European fertility conference how eight Ashkenazi Jewish women who had babies naturally later in life all shared the special genes. The researchers believe the genes might help slow ageing of the ovaries. These women appear to differ from the normal population Dr Neri Laufer They are known to play a role in cell death and DNA repair. It is hoped the work could help the development of better treatments for infertile older women as well as further understanding of the ageing process.

45歳以上で自然出産した女性は、共通した遺伝子特徴を持っているって記事です。しかし250人中8人の遺伝子を調べただけで結論づけるのはキツイですね・・・恐らく追加研究をしているのでしょう。
しかしこの研究、高齢出産を可能にすることにより少子化問題を改善するより、細胞の老化メカニズム全般の解明に役立つといいなぁと個人的には思います。
