摘 要: | 肥胖抑制素(obestatin)和生长激素释放肽(ghrelin)能互相拮抗,参与血糖的调节.其中obestatin与GPR-39(G-protein-coupled receptor 39)结合抑制摄食和胃肠排空、促进胰岛β细胞功能,影响胰岛素的分泌;而ghrelin与生长激素促分泌受体(GHSR1a)结合,促进食欲和胃肠排空,减少脂肪的利用,抑制胰岛细胞凋亡,调节胰岛素的分泌.但两者参与血糖调节的具体机制尚存在争议.

Abstract: | Obestatin and ghrelin participate and antagonize each other in blood glucose regula- tion. Obestatin inhibits food intake, gastrointestinal evacuation and motility, and increases insulin secretion from pancreatic β-cells, whereas ghrelin enhances appetite, gastrointestinal emptying and motility, decreases fat consumption, prevents apoptosis of pancreatic β-cells and human islets thereby controlling insulin secretion. However, the mechanisms of both obestatin and ghrelin in blood glucose regulation remain controversial. |
