| Abstract |
BACKGROUND/AIM:The menadione/ascorbate (M/A) combination has attracted attention due to the unusual ability of pro-vitamin/vitamin combination to kill cancer cells without affecting the viability of normal cells. The aim of this study was to elucidate the role of M/A in targeting cancerous mitochondria. MATERIALS AND METHODS:Several cancer and normal cell lines of the same origin were used. Cells were treated with different concentrations of M/A for 24 h. The cell viability, mitochondrial superoxide, mitochondrial membrane potential, and succinate were analyzed using conventional analytical tests. RESULTS:M/A exhibited a highly specific suppression on cancer cell growth and viability, without adversely affecting the viability of normal cells at concentrations attainable by oral or parenteral administration in vivo. This effect was accompanied by: (i) an extremely high production of mitochondrial superoxide in cancer cells, but not in normal cells; (ii) a significant dose-dependent depolarization of mitochondrial membrane and depletion of oncometabolite succinate in cancer cells. CONCLUSION:The anticancer effect of M/A is related to the induction of severe mitochondrial oxidative stress in cancer cells only. Thus, M/A has a potential to increase the sensitivity and vulnerability of cancer cells to conventional anticancer therapy and immune system. |
