| Outline of Final Research Achievements |
Environment in mammalian oviducts is highly regulated by many endocrine/paracrine/autocrine factors for fertilization and early embryonic development. The present study has revealed that 1) activin A, a local factor, is constantly present in oviductal lumen, 2) oviductal epithelial cells are target of activin A, and 3) mRNA expression of activin receptor is lowest on a day of ovulation in bovine oviduct. In addition, 4) inhibition of activin signal transduction increased pro-apoptotic gene expression in isthmic epithelial cells of bovine oviduct.
