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.}, pages = {352--358}, title = {Vitamin K: Redox-modulation, prevention of mitochondrial dysfunction and anticancer effect.}, volume = {16}, year = {2018} }
