| 2 | Role of plasminogen activator and plasminogen activator inhibitor type-1 in luteolysis——a minireview显示文摘This minireview summarized our recent studies on the role of plasminogen activator (PA) and inhibitor type-1 (PAI-1) in luteolysis. We have demonstrated that (1) both tissue type and urokinase type plasminogen activators (tPA and uPA) and a plasminogen activator inhibitor type-1 (PAI-1) were present in the corpus luteum of rat and rhesus monkey; (2) decrease in progesterone production in corpus luteum was well correlated with a sharp increase in tPA (but not uPA) and PAI-1 secretion; (3) exogenous tPA decreased luteal progesterone synthesis while monoclonal antibodies increased progesterone production; (4) interferon y inhibited luteal progesterone synthesis and stimulated tPA production while LH plus pro-lactin increased progesterone production and decreased tPA (but not uPA) activity in cultured luteal cells; (5) increase in proteolysis in the corpus luteum was also correlated with decrease in progesterone production in mouse. These data suggest that local degradation of extracellular matrix | Liu, YX Chen, YJ Feng, QA Hu, ZY | 1997 | Chinese Science Bulletin1997，42，23： | 0 |
