Background: Arginase 1/ARG1
Arginase and nitric oxidase synthase (NOS) compete for the same L-arginine substrate, creating a delicate balance between pathways (1). Furthermore, bioavailability of L-arginine and ARG1 expression has been implicated in several pathologies including vascular disease, neuronal disease, cardiovascular disease, immune dysfunction, inflammation, and cancer (1,3-5). For instance, ARG1 functions as a macrophage marker, defining the M2 population, while inducible nitric oxide synthase (iNOS) characterizes the M1 population; impaired M1/M2 polarization and changes in ARG1 expression is observed in diseases such as arteriogenesis, asthma, pulmonary fibrosis, and inflammatory bowel disease (1,3). In humans, arginase deficiency, known as argininemia, is an autosomal recessive metabolic disorder characterized by elevated ammonia (hyperammonemia) levels and arginine accumulation (6). Given that many arginase-associated diseases are characterized by upregulation in expression of ARG1, ARG2, or both, arginase inhibitors are currently being studied as a potential therapeutic approach (1,4).
