肿瘤细胞线粒体代谢途径已成为抗肿瘤的关注点。二氯醋酸钠(DCA)是作用于线粒体的小分子物质,显示出一定的抗肿瘤作用。因此,本文考察DCA对C6脑胶质瘤细胞线粒体代谢途径的影响。实验结果显示,DCA可显著增加C6细胞丙酮酸脱氢酶(PDH)的活性、诱导C6细胞氧活性物质(ROS)的生成,显著降低C6细胞线粒体膜电位(MMP)。上述结果表明,DCA可通过激活C6细胞线粒体代谢途径产生抗肿瘤作用。线粒体代谢途径将成为抗肿瘤治疗的新靶点。
Mitochondria are increasingly recognized as important targets for tumor treatment because of their central roles in apoptotic pathways and cellular metabolism. Dichloroacetate (DCA), a low molecular weight mitochondria-targeting agent, exhibits potential therapeutic effects for tumors. Based on the effects of DCA on tumor cellular metabolism, we carried out this study to investigate the anti-tumor activity of DCA in C6 glioma cells in vitro. The results showed that DCA was able to increase the activity of pyruvate dehydrogenase (PDH), induce the production of reactive oxygen species (ROS) and reduce the mitochondrial membrane potential (MMP) in C6 ceils in vitro (P〈0.05 or 0.01), indicating that the anti-tumor effects of DCA in C6 cells could be through the activation of the mitochondrial pathway. In conclusion, mitochondria could be a viable therapeutic target for the treatment of glioma.
