Objective: To explore the contribution of resveratrol (Res) to the proliferation and apoptosis of gallbladder carcinoma (GBC) cell line as well as fibroblast 3T3 cell line in vitro.
Methods: The tumor cell growth repressing rate was measured by the MTT method,and flow cytometry was used to analyse cell cycle. The gene expression of bcl-2 c-myc p53 were examined by SABC.
Results: Res obviously suppressed the proliferation (P <0. 01) in concentration and time dependent manner, it's tiptop was 54%. Res could induce apoptosis of tumor cells. The maximum apoptosis rate of tumor was 30. 52%, experiment group compared with comparison group Gl's cells rised from 34. 88% to 55.47 +/- 3. 95%, S's cells reduced 8.41 - 17.54%, which showed obvious phenomenon of G0/G1 blocking. The GBC cell's bcl-2, c-myc gene reduced expression,while p53 gene increased expression.
Conclusion: The results of this study confirm the ability of Res to suppress the proliferation of gallbladder carcinoma (GBC) cell with a typical apoptotic feature in vitro. Therefore, Res may be considered as a possible treatment strategy for gallbladder carcinoma.
