Abstract

Non-alcoholic fatty liver disease is known to be frequently associated with obesity and type 2 diabetes. We examined the effects of EtOH extracts from Triticum aestivum on lipid accumulation during the differentiation of 3T3-L1 preadipocytes to screening the candidate materials in preventing non-alcoholic fatty liver disease. The lipid level in adipocytes was determined by Oil Red O staining. The treatment of 50% ethanol, but not water and 100% ethanol extracts, from Triticum aestivum at concentration of 0.5 $mg/ml$ inhibited lipid accumulation in 3T3-L1 cells, revealing no cell toxicity. Thus, the fractions of $CH_2Cl_2$, EtOAc and BuOH were separated from 50% EtOH extract to characterize anti-adipogenic effect. The $CH_2Cl_2$ fraction at concentration of $50{\mu}g/ml$ effectively inhibited the lipid accumulation in the adipocytes compared to those of EtOAc and BuOH at concentration of $50{\mu}g/ml$. The intracellular triglyceride accumulation also was significantly reduced by treatment of $CH_2Cl_2$ fraction in concentration-dependent manner. Western blot analysis showed that the $CH_2Cl_2$ fraction attenuated the intracelluar level of fatty acid synthase(FAS) accompanied by attenuated expression of Peroxidase proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$) adipogenic transcription factor. These results suggest that $CH_2Cl_2$ fraction from 50% EtOH extract of Triticum aestivum may has the potent anti-adipogenic effects by inhibiting the transactivation of $PPAR{\gamma}$.
