Influence of all-trans retinoic acid on the invasive potential of epithelial ovarian carcinoma cell line COC2 / 医学研究生学报

ABSTRACT

Objective: To observe the influence of all-trans retinoic acid(ATRA) on the expressions of E-cadherin,heparanase and VEGF in epithelial ovarian carcinoma cell line COC2,and to investigate the anti-metastatic potential and possible action mechanism of ATRA.Methods: We used flow cytometry to examine the expressions of E-cadherin,heparanase and VEGF proteins in the epithelial ovarian carcinoma cell line COC2 treated with different concentrations of ATRA.Results: ATRA significantly increased the expression of E-cadherin and decrease that of VEGF and hepareanse in a dose-dependent manner.Conclusion: ATRA can inhibit cell proliferation,improve cell-cell adhesion and downregulate the expressions of VEGF and heparanse proteins,suggestive of an anti-angiogenic and anti-metastatic potential.
