BACKGROUND: The present study was designed to investigate the effect of wogonin on Caov-3 and A2780 ovary cancer cell proliferation and the mechanisms involved.
MATERIAL AND METHODS: Cell viability changes and apoptosis induction by wogonin were assessed by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenytetrazolium bromide) assay and fluorescence microscopy. Morphological examination of cells was performed using transmission electron microscopy.
RESULTS: Wogonin exhibited inhibitory effect on Caov-3 and A2780 cancer cell proliferation in a concentration-based manner. Caov-3 and A2780 cell proliferation was reduced to 18% and 21%, respectively on treatment with 200 μM concentration of wogonin. Treatment with wogonin significantly enhanced the percentage of A2780 cells showing apoptosis. The nuclear membrane degradation and condensation of chromatin material was evident in A2780 cells on treatment with wogonin. Treatment of A2780 cells with wogonin suppressed the migration potential significantly. The proportion of A2780 cells in G1/G0 phase was markedly raised on exposure to wogonin for 48 hours.
CONCLUSIONS: In summary, this study demonstrated that wogonin acts as an ovary cancer cell proliferation inhibiting agent through activation of apoptosis. Wogonin, therefore, can be investigated further for the development of ovary cancer treatment.
