Abstract:
Objective The purpose of this study was to investigate the effects of gossypol acetic acid (GAA) on protein and mRNA expressions of hMLH1 gene in human tongue carcinoma cell line Tca8113 in vitro in order to discuss the mechanism of tumor suppression of GAA. Methods (1) Western-blot was used to study the effects of GAA on protein expressions of hMLH1 gene in Tca8113 cell line treated by different concentrations of GAA for 48 h. (2) Real-time fluorescence quantitative PCR (RFQ-PCR) was used to investigate the effects on the mRNA expressions of hMLH1 gene in Tca8113 cell line treated by GAA for 48 h. Results (1) Compared with the control group, the results of Western-blot showed that the protein expression of hMLH1 gene was increased after treatment by GAA for 48 h ( <0.05) . (2) The results of RFQ-PCR indicated that the mRNA expression of hMLH1 gene was increased after GAA treatment for 48 h ( <0.05) . Conclusion GAA could up-regulate protein and mRNA expression of hMLH1 in Tca8113 cell line, which indicated that it may be one of the mechanisms of tumor suppression effect of GAA.
