The expression of COX-2 protein in rat endometrium during pregnancy. Total endometrial proteins were collected at indicated days of pregnancy and were analysed by western blotting. Representative blots are shown (2A & 2B). Histograms show densitometric analysis of COX-2 normalized to β-actin to correct for protein loading (2C). Data represents the mean ± SEM of 3-4 independent experiments. Columns with different superscripts are significantly different (p < 0.05). Concentration of PGE2 and PGF2 α metabolites in the serum of pregnant rats (2D&2E). Serum samples were collected at indicated days of pregnancy and the metabolites were measured using a high sensitivity enzyme immunoassay (EIA) kit. Data represents the mean ± SEM of four independent experiments. *Significantly different from all other days of pregnancy (p < 0.05).
