Figure 1From: Expression of COX-1 and COX-2 in the endometrium of cyclic, pregnant and in a model of pseudopregnant rats and their regulation by sex steroidsThe expression of COX-1 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 (1A&1B). Histograms show densitometric analysis of COX-1 normalized to β-actin to correct for protein loading (1C). Data represents the mean ± SEM of 3-4 independent experiments. Columns with different superscripts are significantly different (p < 0.05).Back to article page
