Research Article


In this study, we investigated the hepatoprotective and anti-fibrotic effects of zingerone, one of the active components of ginger, against carbon tetrachloride (CCl4)- and dimethylnitrosamine (DMN)-induced liver injuries in rats, respectively. Oral administration of zingerone (10 mg/kg) reduced CCl4-induced abnormalities in liver histology, serum alanine aminotransferase and aspartate aminotransferase levels, and liver malondialdehyde levels. Zingerone treatment attenuated CCl4-induced increases in inflammatory mediators, including tumor necrosis factor-α, interleukin-1β, cyclooxygenase-2, and inducible nitric oxide synthase mRNA levels. Western blot analysis showed that zingerone suppressed activation of nuclear factor-kappa B (NF-κB) p65 and phosphorylation of extracellular signal-regulated kinase, c-Jun NH2-terminal kinase, and p38 mitogen-activated protein kinases (MAPKs). Liver fibrosis induced by DMN (10 mg/kg, intraperitoneally) was ameliorated by administration of zingerone (10 and 20 mg/kg, orally). Zingerone treatment reduced DMN-induced elevation of hydroxyproline content and hepatic stellate cell activation. In conclusion, zingerone showed antioxidative and anti-inflammatory effects in CCl4-intoxicated rats by inhibiting oxidative stress and NF-κB activation via blockade of the activation of upstream MAPKs. Moreover, zingerone had hepatoprotective and anti-fibrotic effects against DMN-induced liver injury suggesting its usefulness in the prevention of liver inflammation and the development of hepatic fibrosis.
