Popis: Reactive oxygen (oxidant) and free radical species are known to cause nonspecific damage of various biological molecules. The oxidant toxicology is developing an emerging concept of the physiological functions of reactive oxygen species in cell signaling regulation. Redox signaling is precisely modulated by endogenous electrophilic substances that are generated from reactive oxygen species during cellular oxidative stress responses. Among diverse electrophilic molecular species that are endogenously generated, 8-nitroguanosine 3',5'-cyclic monophosphate (8-nitro-cGMP) is a unique second messenger whose formation, signaling, and metabolism in cells was recently clarified. Most important, our current studies revealed that reactive cysteine persulfides that are formed abundantly in cells are critically involved in the metabolism of 8-nitro-cGMP. Modern redox biology involves frontiers of cell research and stem cell research; medical and clinical investigations of infections, cancer, metabolic syndrome, aging, and neurodegenerative diseases; and other fields. 8-Nitro-cGMP-mediated signaling and metabolism in cells may therefore be potential targets for drug development, which may lead to discovery of new therapeutic agents for many diseases.
