摘要:

外泌体(Exosome)存在于动物的各种体液中,如乳汁、血液、尿液等,其中包含的蛋白质、mRNAs、micro-RNAs、脂类等物质,可进入受体细胞而发挥生理作用。近几年有不少关于动物体内各种miRNA的研究,而针对乳exosome中miRNA的研究却相对较少。本文通过对一些已有报道的收集整理,从整体上证实了乳汁中存在miRNA且富集于exosome中,并对比不同动物乳中高表达的miRNA的异同,重点关注exosome中高表达的miRNA,并得出一般性结论。此外,本文还分析了乳中miRNA的其他存在形式,并讨论miRNA在不同动物乳中的保守性及其可能的生理学作用。

Abstract:

Exosome exist in various kinds of body fluid,including milk,serum,urea,etc.It was reported that proteins,mRNAs,microRNAs,lipids,etc in exosome are transferred into receptor cells to play some physiological roles.In recent years,although there are a number of researchs on miRNA in animals,relatively a few studies illustrated miRNAs in milk.In this review,by collecting and collating some reports published,we confirmed the presence of miRNAs in the milk and they enriched in exosome,then compared the similarities and differences of miRNAs with high expression in different animal milk.We also concentrated on miRNAs highly expressed in exosome,and then drew some general conclusions.Moreover,we analyzed the other miRNAs binding forms in milk,then discussed the conservation of miRNAs in different animal milk and possible physiological function of miRNAs.
