| Outline of Final Research Achievements |
Valproic acid(VPA) is well known to be a HDAC inhibitor. When women have taken VPA for epilepsy from their childhood, their ovarian morphology revealed to be polycystic ovary. When VPA was given for pregnant rats, their daughters' ovary revealed to be PCO. Hypermethylation of DNA of the daughter's rats is reported when androgen is given them during pregnancy. In this study, the daughter's ovary revealed to be polycystic ovary. Zucker fa/fa rats with insulin resistance is reported to have hypermethylation of DNA and have polycystic ovary. When we gave pioglitazone(a PPARγactivator) for Zucker fa/fa rats , we succeeded in reduction of small follicles in their ovary. In these results, we realized the existence of very curious relationship between PCOS and epigenome.
