title: [The contribution of invertebrate study to the biology of nitric oxide].
abstract: After the identification of nitric oxide (NO) with the endothelium derived-relaxing factor, many signaling mechanisms involving NO were identified through experiments on Mammals. NO activates soluble guanylyl cyclase leading to the formation of cGMP, stimulates the ADP-ribosylation of GAPDH, altering the cell energy production and combines with superoxide, generating cytotoxic peroxynitrite. NO was then progressively established as a major messenger molecule in Mammals. It is implied in the regulation of blood vessel dilatation, immune function, development and neurotransmission in brain and peripheral nervous system. Later, parallel findings were observed in Invertebrates and then, NO appeared as a signaling molecule widely spread throughout the animal kingdom and whose functions were highly conserved during evolution. The purpose of this short review is to highlight the contribution of Invertebrate studies to the knowledge of NO biology.
