| Outline of Final Research Achievements |
The corpus luteum (CL) is formed in the ovary from an ovulated follicle, and secretes progesterone essential for the establishment and maintenance of pregnancy. In non-fertile cycle, the CL undergoes a regressing stage called luteolysis, while its function is maintained by human chorionic gonadotropin from the implanted embryo during fertile cycle in women. In most animals including mice and ruminants, prostaglandin F secreted from the uterus is an initiator for luteolysis; however, the mechanism how luteolysis in women is regulated is still unknown. We here demonstrated that the changes in the quality and quantity of glycosphingolipids play an important role in the regulation of spontaneous luteolysis in women as well as mice and cows.
