Contributing factors include: reduced nutritional intake (proteins, essential amino acids, competition between amino acid transporters, vitamin insufficiency [riboflavin: GSSG reductase, nicotinic acid: NADPH, pyridoxine (B 6 ): SAMe pathway], mitochondrial dysfunction: ATP deficiency, down regulation SAMe synthase, oxidation of SAMe pathway enzymes, enhanced GSH utilization: conjugation reactions (toxins, drugs), and overwhelming oxidative challenge
Multiple sessions are often required for optimal results, and downtime is generally minimal
DOX increased nitrotyrosine abundance by 68% compared to controls, reflecting heightened oxidative stress
