项目摘要
GLP-1 is one of gastrointestinal hormones, and it has potent anti-obese and anti-diabetic effects. In the present project, we investigated whether indigestible peptides or indigestible saccharides are effective to increase GLP-1 secretion in a cell culture model and animal models. We also examined combined effects of indigestible saccharides and a dietary peptide.We demonstrated that oral administration of a dietary peptide (corn peptide) potently stimulated GLP-1 secretion and it resulted in reduced glycemic response in normal and diabetic rats.Luminal and oral administration of an indigestible saccharide (resistant maltodextrin, RMD) stimulated GLP-1 secretion in rats, and continuous ingestion of RMD also enhanced basal GLP-1 secretion. Furthermore, rats continuously having RMD showed increased GLP-1 secretory response to oral administration the corn peptide. These results revealed potential and combined effects of indigestible saccharides and dietary peptides in vivo.
GLP-1是一种胃肠道激素,具有较强的抗肥胖和抗糖尿病作用。在本项目中,我们研究了在细胞培养模型和动物模型中,难消化肽或难消化肽是否有效增加GLP-1分泌。我们还研究了不消化的甜菜碱和膳食肽的联合作用。(玉米肽)有效地刺激GLP-1分泌,并导致正常和糖尿病大鼠中血糖反应降低。(抗性麦芽糊精,RMD)刺激大鼠中的GLP-1分泌,并且持续摄入RMD也增强基础GLP-1分泌。此外,连续患有RMD的大鼠显示对口服给予玉米肽的GLP-1分泌应答增加。这些结果揭示了潜在的和综合的影响,不消化的脂肪和饮食肽在体内。
