Curcumin protects liver inflammation by suppressing expression of inducible nitric oxide synthase in primary cultured rat hepatocytes

摘要

Background: Curcumin has beneficial effects on organ metabolism. However, there is little evidence that curcumin affects inflammatory mediators, such as tumor necrosis factor (TNF)-α and nitric oxide (NO). In an inflamed liver, proinflammatory cytokines stimulate liver cells, followed by the induction of inducible NO synthase (iNOS). Excessive NO produced by iNOS is one of the factors in liver injury. Therefore, inhibiting iNOS induction for preventing liver injury is important.
