Cytokines Regulate Matrix Metalloproteinases in Human Uterine Endometrial Fibroblast Cells Through a Mechanism That Does Not Involve Increases in Extracellular Matrix Metalloproteinase Inducer

Abstract

These data show that elevated cytokines may play a role in the establishment of ectopic endometrium in the peritoneal cavity by stimulating MMPs to remodel the mesothelial lining of the peritoneum thus allowing for tissue invasion. The stimulation of MMPs by cytokines occurred without any change in EMMPRIN expression whereas the inhibitory effect of TGF-beta(1) involved a reduction in EMMPRIN mRNA levels.
