title: NO generation from inorganic nitrate and nitrite: Role in physiology, nutrition and therapeutics.
abstract: The nitrate-nitrite-NO pathway is emerging as a likely regulator of physiological functions in the gastrointestinal tract and in the cardiovascular system. In particular, it might serve as a backup system to ensure NO like bioactivity also in situations when the endogenous L-arginine/NO synthase pathway is dysfunctional. In addition, this alternative pathway can be harnessed therapeutically in prevention and treatment of disease. Finally, there is an intriguing nutritional aspect to this, since the major supply of nitrate and nitrite in our bodies comes from our everyday diet. Here we review recent advances in this exciting area of research.
