One of the hallmarks of cancer cells is aerobic glycolysis (the Warburg effect). The effect of dichloroacetate (DCA) is to switch glucose metabolism (cellular respiration) to a more efficient process involving oxygen, reduce the production of lactic acid, activate the respiratory chain, change the potential of the mitochondrial membrane, and release pro-apoptotic mediators (cytochrome c and AIF) into the cytosol. As a result, the control over the mutated cells is improved, their sensitivity to various drugs or radiotherapy and their sensitivity to apoptosis increase. In the study the review of data on the mechanism of action of DCA on neoplastic cells was performed to indicate the side effects associated with the possible introduction of this compound to cancer therapy.
癌细胞的特征之一是有氧糖酵解(瓦伯格效应)。二氯乙酸(DCA)的作用是将葡萄糖代谢(细胞呼吸)转变为一个更高效的需氧过程,减少乳酸生成,激活呼吸链,改变线粒体膜电位,并将促凋亡介质(细胞色素c和凋亡诱导因子)释放到细胞质中。结果,对突变细胞的控制得到改善,它们对各种药物或放疗的敏感性以及对凋亡的敏感性增加。在该研究中,对DCA作用于肿瘤细胞的作用机制数据进行了综述,以指出将该化合物引入癌症治疗可能产生的副作用。
