Abstract 3490: Mechanism of action for antioxidant Twendee X on hepatic cancer cell line HepG2
2018
[Purposes of the study] Reactive oxygen species (ROS) are associated with clinical condition of cancer patient, and closely involved in cancer growth and metastasis. Twendee X (TWX) is a composition consisting of Vitamin C, Glutamine, Cystine, Riboflavin, Succinic acid, Fumaric acid, Coenzyme Q10, and Niacin. TWX strongly reduces oxygen radicals or ROS in vitro and in vivo (World Intellectual Property Organization WO2013/072441 A1 COMPOSITION FOR PROTECTION AGAINST CELL-DAMAGING EFFECTS). TWX has significant effects of reducing tumor growth and inhibition metastasis. Hydrogen peroxide level (d-ROMs test) of tumor bearing nude mouse in serum was significantly reduced and increased NK-activity (2016 AACR meeting). Mechanism of action was examined for TWX using hepatic cancer cell line HepG2. [Experimental procedures] Human hepatic cancer cell line HepG2 was used in this study. Cell proliferation experiments of antioxidant by ICDD (France). Metabolome analysis was by Human Metabolome Technologies (Tokyo). In both experiments, HepG2 cell line treated one hour with TWX (60ug/ml). [Data] TWX inhibits the RAF-MEK-ERK pathway starting from ERK. Metabolome analysis shows total shift of metabolism, and especially increase mitochondrial metabolism and ATP production. [Conclusion] Effects of TWX on cancer cell line are not only increase immune activity, but also inhibit proliferation pathway, and mitochondrial metabolism change. Several publications using Vitamin-E or Cysteine as anti-oxidant showed cancer progression or increase metastasis. However, Vitamin-E or Cysteine has limited anti-oxidant effects and hydrogen peroxide level (d-ROMS test) dose not change. On the other hand, TWX has significant effects reduce hydrogen peroxide level, and Japanese Association for Dementia Prevention already started clinical trial for MCI and after stroke patients. For the cancer patients, clinical trial using TWX combination with standard therapy will be start soon. Citation Format: Haruhiko Inufusa.
