Liver fatty acid binding protein has been reported to possess antioxidant properties in the liver. The aim of this study was to investigate the effect of this protein in a nonalcoholic fatty liver disease (NAFLD) cell culture model. Rat hepatoma cells were treated with an oleate:palmitate (2:1) mixture for either 1 and 2 days, or further treated with 500 µM clofibrate to induce L-FABP expression. Intracellular lipid accumulation was quantitated by Nile Red. Lipotoxicity was determined using the WST-1 assay. Dichlorofluorescein (DCF) was utilized to assess intracellular reactive oxidative species (ROS) level. Measurement of lipotoxicity showed statistical decreases in cell viability as lipid concentrations increased in a dose-dependent manner. NAFLD cell cultures showed characteristic cellular damage from increased ROS levels in fatty acid treated cells. All groups treated with clofibrate showed statistically increased intracellular L-FABP levels and reduced ROS levels. The results lead to the conclusion that clofibrate induces L-FABP expression and in this manner suppresses hepatocellular ROS generation.
