Estradiol (E2) and progesterone are responsible for regulating PG synthesis in the endometrium during the estrous cycle and interferon-τ (IFN-τ) alters PG synthesis during early pregnancy in ruminants. In this study, we examined the effects of these steroid hormones and recombinant bovine IFN-τ (rbIFN-τ) on PG production and on cyclooxygenase-2 (COX-2) and PG F (PGF) synthase (PGFS) gene expression in isolated endometrial cells. E2 decreased both PGF2α and PG E2 (PGE2) whereas progesterone increased PGF2α secretion in epithelial cells. Steroid hormones had no effect on PG production in stromal cells. rbIFN-τ attenuated both PGF2α and PGE2 production in epithelial cells and enhanced their production, and the ratio of PGE2 to PGF2α, in stromal cells. Northern blot analysis showed that E2 and rbIFN-τ decreased COX-2 messenger RNA (mRNA) levels in epithelial cells. Conversely, rbIFN-τ increased COX-2 mRNA in stromal cells. Furthermore, rbIFN-τ decreased PGFS mRNA in both cell types and this was associated wit...
