ABSTRACT
The aim of this paper was to investigate the mechanism and effect of psoralen and isopsoralen in the treatment of lipid accumulation in LO2 cells. Human LO2 cells nonalcoholic fatty liver models were established by using palmitic acid( PA). Then psoralen and isopsoralen were administered for intervention. Intracellular triglyceride( TG) and total cholesterol( TC) content,the cell supernatant alanine aminotransferase( ALT) and aspartate aminotransferase( AST) levels were determined by enzyme method. Cell supernatant proinflammatory cytokines( IL-6,TNF-α) and chemokines( IL-8,MCP-1) were determined by ELISA method. Western blot method was conducted to detect the protein expression of intracellular nuclear factor( NF-κB) p65 phosphorylation( p-p65),nonphosphorylated protein( p65),and transforming factor TGF-β1. Result showed that as compared with the model group,intracellular TG and TC levels,the cell supernatant ALT and AST levels,proinflammatory cytokines and chemokines were decreased( P < 0. 01,P <0. 05); the p-p65/p65 ratio and TGF-β1 protein expression were also significantly decreased( P< 0. 01,P< 0. 05) in psoralen intervention group. As compared with the model cells,intracellular TG content had no significant changes,but all the other indexes were reduced( P<0. 01,P<0. 05) in the cells of isopsoralen intervention group. Psoralen exhibited better effect than isopsoralen( P< 0. 01,P<0. 05). It is concluded that psoralen could improve the adipogenesis of LO2 cells induced by PA; both psoralen and isopsoralen are effective in ameliorating LO2 cells injury induced by PA,reducing inflammation via inhibiting the activation of NF-κB and down-regulating the expression of TGF-β1.
