本文综述了维生素K的氧化还原调节特性和抗癌作用。这一概念集中在两个方面:(i)维生素K的氧化还原循环及其对钙稳态、“致癌”和“抑癌”活性氧以及癌症中氧化应激的特异性诱导的影响;(ii)维生素K加C作为强大的氧化还原系统,其在线粒体复合物II和III之间形成旁路,从而防止线粒体功能障碍,恢复氧化磷酸化和有氧糖酵解,调节内源性氧化还原对的氧化还原状态,消除癌细胞的缺氧环境并诱导细胞死亡。分析的数据表明,维生素C和K可以使癌细胞对常规化疗敏感,从而可以实现较低的药物有效剂量并最大限度地减少有害的副作用。这篇评论是为广大读者准备的--从学生到该领域的专家。
This review is directed to the redox-modulating properties and anticancer effect of vitamin K. The concept is focused on two aspects: (i) redox-cycle of vitamin K and its effect on the calcium homeostasis, “oncogenic” and “onco-suppressive” reactive oxygen species and the specific induction of oxidative stress in cancer; (ii) vitamin K plus C as a powerful redox-system, which forms a bypass between mitochondrial complexes II and III and thus prevents mitochondrial dysfunction, restores oxidative phosphorylation and aerobic glycolysis, modulates the redox-state of endogenous redox-pairs, eliminates the hypoxic environment of cancer cells and induces cell death. The analyzed data suggest that vitamin C&K can sensitize cancer cells to conventional chemotherapy, which allows achievement of a lower effective dose of the drug and minimizing the harmful side-effects. The review is intended for a wide audience of readers - from students to specialists in the field.
