Figure 1 Regulation of Nitric oxide (NO) and polyamine pathways. H pylori induces inducible nitric oxide synthase (iNOS) expression, arginase II and ornithine decarboxylase (ODC). iNOS competes with arginase for arginine. Gastric cancer relates to the high expression of iNOS. H pylori-induced iNOS is inhibited by spermine produced by the arginase-ODC pathway.
