NADH is the reduced form of NAD⁺, meaning it has accepted electrons (and usually a proton) during metabolic reactions. When NAD⁺ accepts electrons (typically during metabolic processes like glycolysis, the citric acid cycle, and beta-oxidation), it becomes NADH.
-By influencing the balance between NADH and NAD⁺, ENOX2 might shift the cellular redox state. An imbalance can lead to increased oxidative stress or changes in ROS signaling pathways.
• The ratio between NADH and NAD⁺ is a key indicator of a cell’s metabolic state.
• Some studies have suggested that abnormal NADH metabolism or shifts in the NADH/NAD⁺ ratio can be correlated with tumor aggressiveness or response to therapy.
• For example, in certain cancers, a higher NADH/NAD⁺ ratio may be associated with more aggressive behavior, resistance to apoptosis, or poor prognosis.
