Ghrelin基因能通过选择性剪切和翻译后修饰生成多种产物,如酰基化acyl-ghrelin、非酰基化des-acyl-ghrelin、obestatin等,其功能包括促进生长激素释放、调节摄食和糖脂代谢、保护心肌和血管内皮细胞、调节免疫和炎症反应等。本文介绍了ghrelin基因的多种产物,重点讨论acyl-ghre-lin、des-acyl-ghrelin和obestatin的功能。
By alternative splicing and posttranslational modification, ghrelin gene encodes multiple prod- ucts ranging from acyl-ghrelin, des-aeyl-ghrelin, to obestatin. These products exhibit diverse functions such as stimulating growth hormone secretion, regulating food uptake, glucose and lipid metabolism, pro- tecting cardiovascular system, and modulating immune and inflammation. This review summarizes the re- cent advances on the products of ghrelin gene and their diverse functions.
