Microbial lipopeptides play an important role in apoptosis induction of tumor cells. However, there is little knowledge about the relationship between apoptosis induction and membrane fatty acids. The present study focused on the effects of lipopeptides produced by Bacillus subtilis HSO121 on Bcap-37 cell lines. 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl (MTT) colorimetric assay and surface tension measurements, showed that the critical micelle concentration (CMC) was a critical level for the inhibitory activity of lipopeptides on the growth of Bcap-37 cells. Under the CMC, the order of least to greatest cytotoxicity effect on cancer cell lines by lipopeptides is C(13)-lipopeptide &lt; C(14)-lipopepitde &lt; C(15)-lipopeptide. Above CMC, all lipopeptides directly exert cytolytic activity. The flow cytometric analysis and Hoechst33258 staining experiments confirmed the apoptosis of Bcap-37 cell lines induced by lipopeptides in a dose-dependent manner. This apoptosis was associated with a significant decrease of the unsaturated degree of the cellular fatty acids of Bcap-37 cell lines due to the changes in the cellular fatty acids composition induced by the lipopeptide treatment. These results indicated that disturbance of the cellular fatty acid composition of breast cancer cell lines were related to in the cell apoptosis. Furthermore, significant difference in IC(50) values of tumor cells and normal cell showed that the lipopeptide exerted selective cytotoxicity on the cancer cells. Thus HSO121 lipopeptides may have potential applications as an anticancer leads.
