Changes in plasminogen activator activity induced by different concentrations of 17β-estradiol (E₂; 0, 0.2, 2, 20, and 200 ng/mL; A), interleukin-1β (IL-1β; 0, 0.1, 1, 10, and 100 ng/mL; B), and human chorionic gonadotropin (hCG; 0, 0.5, 1, 1.5, and 2 IU/mL; C) in porcine endometrial cells. All data were presented as mean±SEM from 3 repeated experiments. ^a-c Different superscript indicates a significant difference (p<0.05). PA, plasminogen activator; hCG, human chorionic gonadotropin; GAPDH, glyceraldehyde 3-phosphate dehydrogenase.
