Methods： Ovarian cancer cells A2780 were treated with different concentrations of SCR extract （SCRE）, and compared with controls. Effects on cell growth were evaluated by cell counting kit-8 （CCK-8） assay; proliferation effects by EdU incorporation assay; cell cycle by propidium iodide staining; apoptosis by annexin V-fluorescein isothiocyanate/propidium iodide; cellular distribution of nuclear factor- κ B （NF-κ B） by immunofluorescence; protein levels of NF- κB, caspase-3, poly-adenosine diphosphate （ADP）-ribose polymerase （PARP）, Bcl-2-associated X protein （Bax）, cellular inhibitor of apoptosis （clAP）-1, anti-X-linked inhibitor of apoptosis protein （XlAP）, B-cell lymphoma-extra large （BcI-XL）, B-cell lymphoma-2 （Bcl-2） and AKT by Western blotting; and effects of SCRE combined with cisplatin or adriamycin on A2780 cells by CCK-8 assay. Results： SCRE suppressed A2780 cell proliferation in a dose-dependent manner （P〈0.05, /=〈0.01）, arrested cells in GJM phase and induced apoptosis by activating caspase-3, PARP and Bax. SCRE treatment also correlated with inhibition of NF-κ B and downregulation of Bcl-2, Bcl-XL, clAP-l, XlAP and AKT. SCRE can promote chemosensitivity to cisplatin and adriamycin in A2780 cells （P〈0.01）. Conclusion： SCR effectively inhibits NF- κ B, induces apoptosis and reduces chemoresistance to cisplatin and adriamycin in ovarian cancer cells, which might be its molecular basis for treating ovarian cancer.展开更多
