Human ovarian neoplasm cell CD147 stimulates production and activation of matrix metalloproteinases in co-cultures with mouse fibroblasts

摘要

Objective: To investigate the expression of CD147 on human ovarian neoplasm cell lines and its influence on production and activation of matrix metallproteinases (MMPs). Methods: The expression of CD147 on different human ovarian neoplasm cell lines was studied by western blotting. Co-culture was carried out to investigate the stimulative effect of the positive expression CD147 cell HO-8910 on the production of MMPs of fibroblast cell in vitro. Zymography and immune blotting were used to study the production and activity of positive MMPs, at the time, to explore the relation between CD147 and MMPs. Results: CD147 was positively presented in 2 ovarian neoplasm cell lines (HO-8910, 3-AO), but in SKOV3, TC-1, NIN3T3 cell was negative. MMP-2 and MMP-9 were detected by HO-8910 cell line, mouse fibroblast cell and co-culture cells; but the expression in co-culture cell is obviously higher than individual cultures of each type alone. CD147 stimulated MMPs in dose-dependent manner. Conclusion: CD147 causes increased production and activation of MMP-2, MMP-9. CD147 is probably a indirect marker of some ovarian cancer cells with invasion and metastasis.
