Expression of cyclooxygenase-II (COX-II) and 20alpha-hydroxysteroid dehydrogenase (20alpha-HSD)/prostaglandin F-synthase (PGFS) in bovine placentomes: implications for the initiation of parturition in cattle.
The chain of events leading to prepartal luteolysis in cattle is not yet fully understood. Prostaglandin F(2alpha) (PGF(2alpha)) seems to be a major factor involved. However, only little information is available about the underlying regulatory mechanisms. Consequently, the expression of cyclooxygenase-II (COX-II) and 20alpha-hydroxysteroid dehydrogenase… (More)
