An enzyme that produces nitric oxide (NO) in response to inflammatory stimuli.
iNOS can promote tumor growth by enhancing blood flow and nutrient supply to tumors through vasodilation. It may also help cancer cells evade apoptosis (programmed cell death).
Immune Activation: In some contexts, NO produced by iNOS can enhance the immune response against tumors, promoting the activation of immune cells that can target and destroy cancer cells.
Inhibition of Tumor Growth: High levels of NO can induce cytotoxic effects on tumor cells, leading to reduced proliferation and increased apoptosis.
