Abstract

The anti-lipogenic effect of cereal samples on high sucrose diet (HSD)-induced non-alcoholic fatty liver disease (NAFLD) in mice was studied. We divided C57BL/6 mice into various groups based on 8 weeks of treatment with three types of cereal samples (HSD+WR, HSD diet containing 40% white rice; HSD+MCG, HSD diet containing 40% mixed cereal grain; HSD+AO-MCG, HSD diet containing 40% mixed antiobesity-cereal grain). After the experimental period, body weight changes, liver weights, serum lipid profiles, and hepatic fatty acid metabolism-related gene expression levels were determined. We found that HSD+WR, HSD+MCG, and HSD+AO-MCG treatments reduced body weight and liver weight, especially HSD+MCG and HSD+AO-MCG effectively reduced levels of serum triglycerides, total cholesterol, and low-density lipoprotein cholesterol. However, high density lipoprotein cholesterol levels increased compared to the control group. Furthermore, expression of hepatic lipogenic genes such as sterol regulatory element-binding protein-1c, acetyl-coenzyme A carboxylase, fatty acid synthase, stearoyl-coenzyme A desaturase-1, cluster of differentiation, and $PPAR-{\gamma}$ (peroxisome proliferator activated receptor ${\gamma}$) decreased, whereas expression of ${\beta}-oxidation$ genes such as $PPAR-{\alpha}$ and carnitine palmitoyl transferase-1 increased following HSD+MCG and HSD+AO-MCG treatment compared with levels in HSD+WR and control groups. These results suggest that the functional cereal samples, especially HSD+AO-MCG treatment, improved hepatic steatosis triggered by an HSD-induced imbalance in hepatic lipid metabolism.

본 연구에서 고당식이로 비알코올성 지방간을 유도한 마우스의 체중 변화는 대조군보다 백미군, 혼합잡곡군, 항비만혼합잡곡군에서 체중증가율이 낮았고 간 무게 또한 유의적으로 감소했으며, 간 내 조직학적 지방구 수와 크기가 감소한 것을 관찰할 수 있었다. 혈청 지질 수치 역시 개선 효과를 보였는데 모든 실험군이 대조군보다 중성지방, 총콜레스테롤 및 저밀도 콜레스테롤의 농도가 감소하였고, 혈청 고밀도 콜레스테롤은 모두 증가하였다. 간 조직 내 지질합성 및 지방산 침투와 관련 유전자 인자에서 대조군보다 SREBP-1c mRNA 유전자 발현 수준은 백미군, 혼합잡곡군 및 항비만혼합잡곡군에서, ACC 및 FAS mRNA 유전자 발현 수준은 혼합잡곡군과 항비만혼합잡곡군에서, SCD-1 mRNA 유전자 발현 수준은 항비만혼합잡곡군에서 감소하였다. CD36 및 $PPAR-{\gamma}$ mRNA 유전자 발현 수준 또한 대조군보다 백미군, 혼합잡곡군, 항비만혼합잡곡군에서 감소하였다. 간 내 ${\beta}$산화로 지방축적 억제와 관련된 유전자 인자인 $PPAR-{\alpha}$ 및 CPT-1 mRNA 유전자 발현 수준은 대조군보다 혼합잡곡군, 항비만혼합잡곡군에서 증가하였다. 본 실험 결과를 종합해 볼 때 고당식이로 비알코올성 지방간질환을 유도한 마우스에서 백미군, 혼합잡곡군 및 항비만혼합잡곡군 모두 지질 대사 개선 효과가 나타났으며 항비만혼합잡곡군이 가장 효과적이었다.
