The anti-proliferation effect of Aikete injection on hepatocellular carcinoma in vitro and in vivo
2011
Context: Aikete injection is composed of acetylshikonin and β,β-dimethylacrylshikonin, which have been reported to have anti-tumor effects on a wide range of cancer cell lines. However, little is known about the effects of the combination of the two components on cancer cells.Objective: To investigate the anti-proliferation activity of Aikete injection on human hepatocellular carcinoma (HCC) cells and its mechanism.Materials and methods: 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay and growth curve assay were used to determine the inhibitory effect of Aikete injection on the proliferation of SMMC-7721 cells. Giemsa staining, Hoechst 33258 staining and flow cytometry were used to assess cell apoptosis. Expression of Bcl-2 and Bax was analyzed by reverse transcription-polymerase chain reaction and flow cytometry. H22 bearing mice were also used to determine the anti-tumor effect of Aikete injection in vivo.Results: Aikete injection inhibited the proliferation of SMMC-7721 cells in bot...
