摘要: 外泌体(exosomes)是一类由细胞分泌并且可远距离传递生物信息的纳米级胞外囊泡。它通过细胞分泌释放,在体液中传播,最后被其他细胞吞噬以达到传递生物信息的作用。脂类代谢一直是生命科学研究领域的热点,虽然影响脂质代谢的长链非编码RNA(lncRNA)很多,但外泌体中影响脂质代谢的lncRNA研究却相对较少。基于这个原因,对于外泌体源lncRNA的研究就十分必要。作为外泌体所携带的重要遗传物质之一,lncRNA是一类长度 > 200 nt的RNA分子,行使着诸如转录激活、染色质修饰等许多重要的生物功能。文章介绍了外泌体源lncRNA的生物学特点,列举了外泌体源lncRNA通过不同的分子机制来直接或间接的对脂质代谢产生影响的实例,分析了外泌体源lncRNA由于表达异常所导致的脂类代谢疾病,并且举例说明了外泌体源lncRNA作为生物标记的原理,最后对外泌体源lncRNA可作为家畜脂肪沉积生物标记功能的前景做了展望。如果在未来的研究中有更多的外泌体源lncRNA被检出,并足够对脂类代谢异常情况进行标记的话,那么对于预测和调控家畜脂肪沉积无疑会产生积极的意义。

Abstract: Exosomes are a kind of nanometer extracellular vesicle secreted by cells and they are able to transmit biological information in a long distance.Exosomes are secreted and released by cells,then transmitted in body fluids,finally swallowed in another cells to transmit biological information.Lipid metabolism has always been a hotspot of the field of life science research.Although there are many lncRNAs affecting lipid metabolism,there are relatively few lncRNAs studies affecting lipid metabolism in exosomes.For this reason,the study of exosomal-lncRNAs shows it’s necessity.As one of the important genetic material carried by the exosomes,the long non-coding RNAs are a kind of RNA molecule of which length for more than 200 nt,and perform many important biological functions such as transcriptional activation,chromatin modification and so on.In this paper,the biological characteristics of the exosomal-lncRNAs have been introduced,and the examples of the effect of exosomal-lncRNAs on lipid metabolism by different molecular mechanisms have been listed.The lipid metabolism disease caused by the abnormal expression of exosomal-lncRNAs has analyzed,and the principle of the exosomal-lncRNA acted as lipid metabolism disease’s biomarker has also illustrated.Finally,the prospect of exosomal-lncRNA as a biomarker for animal fat deposition has prospected.If more exosome-derived lncRNAs are detected in the future research,and it’s sufficiently to label abnormal conditions of lipid metabolism,there will undoubtedly be positive implications for the prediction and regulation of fat deposition in livestock.

Key words: exosomes; long non-coding RNA (lncRNA); lipid metabolism
