Abstract: The aim of this study was to clarify the effects of estrogen (E2) on cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) gene expression in the cow oviduct tissue in vitro.Quantitative Real-time PCR and Western blotting were used to analyze the mRNA and protein expression of COX-1 and COX-2 at different time points after different concentrations of E2 treatment.The results indicated that the relative expression of COX-1 and COX-2 mRNA reached the highest levels with 10-11 mol/L E2 treatment,the relative expression of COX-1 mRNA reached the highest level at 8 h after treatment;The relative expression of COX-2 mRNA reached the highest level at 2 h after treatment.The relative expression of COX-1 protein increased significantly at the range from 8 to 48 h after E2 treatment.However,we did not detect COX-2 protein expression.

Key words: oviduct; cyclooxygenase-1; cyclooxygenase-2; estrogen (E2)
