| Abstract | Objective: To investigate the proliferation effect and its pathway of activin A on Ovarian epithelial cancer cells line OVCAR-3. Methods: OVCAR-3 cells were cultured in vitro and the membrane receptor ActR II was detected by immunohistochemical method. The OVCAR-3 cells were cultured with 10 ng/ml activin A for 7 d to observe the effects. Activin A at 5, 10, 15 and 20 ng/ml was used separately to treat the OVCAR-3 cancer cells for 24, 48 and 72 h in order to draw the growth proliferation rate curve measured by MTT method. The expression of protein bcl-2 was detected by western-blot. When OVCAR-3 cells were treated with 10 ng/ml activin A and 5 mu g/ml DDP for 24, 48 and 72 h, cell apoptosis could be detected by electron microscopy and flow cytometry (FCM). Results: Positive expression of ActR II was detected. We also found that the proliferation of OVCAR-3 reached to the climax on the 5th day of culture. The experiments showed that the cells treated with activin A increased quickly and grew faster than those in control group. Moreover, OVCAR-3 cells treated with activin A for 48 h proliferated significantly greater than those treated for 24 h or 72 h (P < 0.01). bcl-2 protein expression increased expression in activin A treated group than in control group (P < 0.05). Conclusion: Activin A could increase the proliferation of OVCAR-3 cells which may be through bcl-2 anti-apoptosis pathway. |
