Abstract:: |
Objective To study the effect of sanguinarine on the growth and radiosensitivity of ovarian cancer SK-OV-3 cells. Methods Cell growth was determined by MTT and clonogenic assay. Cell cycle analysis was performed by flow cytometry assay. The cell apoptosis was analyzed by Annexin V/PI assay. Results Sanguinarine inhibited SK-OV-3 cell growth in a dose-and time-dependent fashion and its IC50 values were 3.02 and 1.11 μmol/L at 24 and 48 h, respectively. Sanguinarine also significantly triggered a sub-G1 peak, an indicator of apoptosis, and caused a G0/G1 arrest. Furthermore, the cell apoptosis induced by X-irradiation was significantly increased at 6 Gy when the cells were pre-treated with sanguinarine, in which the early apoptotic population increased from 10.28% to 43.28% (t=19.41, P<0.01) and the late apoptotic population increased from 20.26% to 30.80% (t=8.78, P<0.01). The multi-target click model was used to fit survival curves and the SER of sanguinarine treatment approached to 1.625 at the dose of D0. Conclusions Sanguinarine could inhibit SK-OV-3 cell growth by inducing apoptosis and cell cycle arrest and enhance cell radiosensitivity at low doses. |
