BACKGROUND Various molecules participate in implantation and maintaining endometrial function during gestation. The remodeling of endometrial matrices is a necessary process in the coordination of gestational progress. Matrix-metalloproteinases (MMPs) like gelatinases (MMP-2 and -9) and collagenase (MMP-1) are considered to play important roles in this process. We examined MMP-2 and -9 expressi...
The Effect of Imbalanced Progesterone Receptor-A/-B Ratio on Gelatinase Expressions in Endometriosis
Objective Objective: Gelatinases degrade extracellular matrix (ECM) components to make physiological remodeling and contribute to pathological tissue destruction in endometriosis. It is known that gelatinases’ function is resistant to suppression by progesterone in endometriosis. The ability of progesterone to impact gene expression depends on the progesterone receptor-A/-B (PR-A/PR-B) ratio. A...
The Gates photographic film method for pepsin estimation as developed by Gilman and Cowgill measures an activity corresponding to that determined by the hemoglobin method of Anson and Mirsky rather than that resulting from the use of the gelatin viscosity technique. Therefore, the presence of gelatinase is not a source of great error in the gelatin film procedure.
Extracellular matrix-degrading gelatinases are mainly involved in tumor invasion and metastasis. Previous experimental data from our group and others suggested that homocysteine could have a potential modulatory role on the proteolytic balance at the extracellular matrix. Therefore, we studied the effects of homocysteine on extracellular matrix-degrading proteases using model human tumor cell l...
