CCl4-induced hepatic injury in mice fed a Western diet is associated with blunted healing.

ABSTRACT:

Background and aims

Feeding a Western diet (WD) enriched in saturated fat protects against chronic alcoholic hepatitis. However, saturated fat induces lipotoxicity in cultured hepatocytes. The purpose of the present study was to elucidate the influence of WD on acute hepatic injury and healing.

Methods

Male C57BL/6 mice were fed a purified control diet (CD) or WD enriched in palmitate and cholesterol. After 3 weeks, carbon tetrachloride (CCl(4)) was administered (0.1 microL/g, intraperitoneally). Hepatic inflammation and proliferation were assessed by immunostaining for neutrophils and intracellular adhesion molecule-1, and Ki67, respectively. Cytokine expression was analyzed by real-time polymerase chain reaction. Protein levels of peroxisome proliferator-activated receptor
