Kamut (Triticum turgidum spp.) 식빵 급여가 고지방식이 유도 비만 C57BL/6 마우스에 미치는 효과

Abstract

Objectives: The purpose of this study was to investigate the effect of white pan bread added with Kamut (Triticum turgidum spp.) on high fat diet (HFD)-induced obese C57BL/6 mice. Methods: The white pan bread or white pan bread with Kamut (BK) were administered for 8 weeks in HFD-induced obese C57BL/6 mice. To evaluate the effect and its mechanisms of BK on obese mice, we measured body weight change, serum lipid profiles, histopathological analysis, and protein expression of CCAAT/enhancer binding protein-α (C/EBPα) in the liver. Results: Administration of BK significantly decreased body weight in HFD-induced obese mice. In addition, BK-administered group significantly reduced serum total cholesterol, glucose, and high-density lipoprotein cholesterol levels compared with the HFD-induced control group. The HFD-induced mice had damaged liver tissue and increased the size of adipose tissue, but BK-administered group attenuated liver damage and decreased the size of adipocyte. Furthermore, administration of BK significantly down-regulated C/EBPα in the liver compared with HFD-fed mice. In particular, BK-administered group has higher inhibited body weight, serum lipid profiles, and C/EBPα expressions than white pan bread-administered group. Conclusions: This study demonstrated that administration of BK attenuated HFD-induced obesity by regulation of C/EBPα than consumption of white pan bread. Therefore, BK could be developed as a bread for prevention of obesity.
