Rapid reduction of nitric oxide by mitochondria, and reversible inhibition of mitochondrial respiration by nitric oxide.
Nitric oxide (NO) inhibited the respiration rate of mitochondria isolated from rat heart at sub-micromolar concentrations of NO. The inhibition was rapidly and completely reversible, indicating that NO does not damage mitochondria. The sensitivity of respiration to NO depended on the oxygen concentration, substrate type and respiratory state of the mitochondria, consistent with NO competing wit...
متن کاملOxygen-dependent reversible inhibition of mitochondrial respiration by nitric oxide.
Effects of nitric oxide (NO) and NO generating agents, on the electron transport system of mitochondria were examined in a study of the mechanism and physiological importance of NO in energy metabolism. In the presence of various substrates, uncoupled respiration was inhibited by NO in manner which was both dose- and oxygen tension-dependent. Simultaneously measuring changes in cytochrome absor...
متن کاملInhibition of glucocorticoid receptor binding by nitric oxide.
Septic shock is a dangerous condition with high mortality rates. In sepsis, the inducible form of nitric oxide (NO) synthase is induced, releasing high amounts of NO. Glucocorticoids have potent anti-inflammatory properties and are very effective in inhibiting the induction of this enzyme if administered before the shock onset. It is known that glucocorticoid receptor (GR) has critical cysteine...
متن کاملInhibition of Nitric Oxide Production and Proinflammatory Cytokines by Several Medicinal Plants
Background: A number of medicinal plants have been used to treat various immunological diseases. Nitric oxide (NO) has an important regulatory role in the various types of inflammatory processes. Objective: To investigate the NO modulatory activity of the extracts of several medicinal plants native to Iran including Dracocephalum kotschyi, Linum persicum, Dionysia termeana, Salvia mirzayanii, F...
متن کاملL-Glutamin-Induced Inhibition of Endotoxemia by Reducing Pre-Inflammatory Cytokines, Nitric Oxide, and CD40 Expression
Introduction: Researchers have been investigating the major pathogens involved in septic shock caused by lipopolysaccharide in recent years. Moreover, they have been concerned about the use of appropriate drugs to intervene with the main pathogenesis of the disease. This study aimed to investigate the effect of L-Glutamine as an HSP70 inducer in reducing pre-inflammatory cytokines and effective...
