Through substrate competition between iNOS and Arg1, arginine couples inflammatory NO production with polyamine/reparative metabolic branches, thereby regulating the balance between pro-inflammatory cytotoxicity and tissue repair within the same substrate framework ( Taking TCA cycle reprogramming as an example, pro-inflammatory activation is often accompanied by TCA cycle disruption and the accumulation of signaling intermediates, among which succinate has been shown to promote IL-1 production and amplify inflammatory responses through HIF-1 (132)

LOOH also participates in regulating oxidative stress-related signaling pathways, influencing apoptosis and antioxidant defense mechanisms [93], underscoring its critical role in cardiovascular diseases such as atherosclerosis and in neurodegenerative diseases, triggering tissue damage and pathological progression [93]
