physiological function | nicotinamide N-methyltransferase is involved in the biotransformation and detoxification of many drugs and xenobiotic compounds, it enhances the capacity of tumorigenesis associated with the promotion of cell cycle progression in human colorectal cancer cells. The enzyme significantly accelerates cell proliferation, enhances colony formation in vitro and tumorigenicity in mice, and inhibits apoptosis, it promotes cell cycle progression, increases ATP and 1-methylnicotinamide level and decreases ROS levels. 1-Methylnicotinamide also accelerates cell growth, inhibits apoptosis, promotes cell cycle progression, attenuates ROS production and increases ATP levels. The enzyme may play a vital role in energy balance and ROS induction, 1-Methylnicotinamide is beneficial in conditions such as inflammation and antioxidation | Homo sapiens |
