Abstract

Ovarian steroids assure an optimum environment for the final maturation of oocytes, gamete transport, fertilization, and early embryonic development. The aim of experiment 1 was to examine the influence of ovarian steroids on tumor necrosis factor-α (TNF-α) or nitric oxide (NO)regulated prostaglandin (PG), and nitrite/nitrate (NO2/NO3) secretion by cultured bovine oviductal epithelial cells (BOECs). BOECs were pretreated with 17β-estradiol (E2; 109 M) and/or progesterone (P4; 107 M) for 24 h. For the next 24 h, BOECs were treated with TNF-α (10 ng/mL) or spermine nitric oxide complex (NONOate; 105 M). Prostaglandin F and PGE2 secretion was measured in medium by ELISA. The pretreatment of cells with P4 (progesterone), E2 (17 β-estradiol), or E2/P4 augmented TNF-αinduced PGF and PGE2 secretion (P <0.01). The pretreatment of cells with E2 or E2/P4 increased NONOate-induced PGF and PGE2 secretion (P <0.01). TNF-α induced NO2/NO3 production by BOECs. The pretreatment of cells with E2 augmented only TNF-αnduced NO2/NO3 production (P <0.05). The aim of experiment 2 was to examine the influence of TNF-α, NO, and ovarian steroids on the protein content of enzymes specifically involved in PG and NO production, PG synthases, and NO synthases (NOSs). BOECs were treated with TNF-α (10 ng/mL) or NONOate (105 M). TNF-α increased the protein content of PGG/H synthase, PGF synthase, and PGE synthase (P <0.05) and endothelial and inducible NOSs (P <0.05). Nitric oxide increased the protein content of PGF synthase, PGE synthase, endothelial NOS, and inducible NOS (P <0.05). These results show possible linkage between TNF-α and NO, modulated by ovarian steroids, in the regulation of PG synthesis by BOECs that may be important for triggering the process of oviductal contractions.
