Abstract/OtherAbstract:
To explore the effects of Tanshinone II A on the proliferation, apoptosis and gene expression of p53 and bcl-2 in human gastric carcinoma MKN-45 cells. Cell count and MTT assay were used to study the proliferation-inhibiting effect of Tanshinone II A on MKN-45 cells. The effect of Tanshinone II A on the cell cycle and apoptosis of MKN-45 cells were examined by propidium iodide (PI) staining and flow cytometry. Semi-quantitative RT-PCR was used to further verify the expression of p53 and bcl-2 gene after exposure to Tanshinone A in MKN-45 cells. The results showed that Tanshinone A significantly inhibited the growth and proliferation of MKN-45 cells in a dose-and time-dependent manner (P<0.05). Tanshinone A arrested MKN-45 cells in G(2)/M phase which led to an obvious accumulation of G(2)/M phase cells while decreased number of G(0)/G(1) phase cells. This resulted in apoptosis of MKN-45 cells and the apoptosis rate was as high as 43.91% after treatment with 2.0 microg/mL Tanshinone II A for 96 h. It was also found that Tanshinone II A up-regulated expression of p53 gene and down-regulated expression of bcl-2 gene. The cytostatic and antiproliferative effect of Tanshinone II A makes it a promising anticancer agent for the treatment of gastric carcinoma.
