mRNA analysis of several components of the plasminogen activator and matrix metalloproteinase systems in endometriosis using a real-time quantitative RT-PCR assay.
Two systems of secreted proteases in the endometrium, the plasmin(ogen) activator/inhibitor and the matrix metalloproteinases and their inhibitors were examined in cell cultures of uterine endometrial cells from women with and without endometriosis.
We have previously demonstrated elevated levels of the fibrinolytic factors urokinase plasminogen activator (uPA) and plasminogen activator inhibitor (PAI-1) in endometriotic tissue and endometrium from women with endometriosis.
