摘要: 为探究驴乳外泌体中微小RNA(miRNA)的种类和功能性,利用Illumina测序技术对驴乳外泌体中非编码小RNA(sRNA)进行测序分析,鉴定其中的miRNA并以人乳外泌体miRNA作为对照组进行生物信息学分析。驴乳外泌体中sRNA在质量控制之后,长度主要分布在18~22 nt,在其中共鉴定到212 个miRNA,其中包括16 种已知miRNA和196 种新miRNA。基因本体论富集分析发现,驴乳外泌体miRNA的功能性与人乳相似,构成细胞、细胞器等组分;具有结合和催化活性等功能;参与细胞代谢、生物调节等过程。京都基因与基因组百科全书通路富集分析发现,驴乳外泌体miRNA参与醛固酮的合成与分泌、Hedgehog信号、线粒体调节、癌症等通路。

Abstract: In order to explore the species and functions of microRNAs (miRNAs) in donkey milk exosomes, Illumina sequencing technique was used to sequence the small non-coding RNAs (sRNAs) in donkey milk exosomes, and identify the miRNAs in them through bioinformatic analysis using human milk miRNAs as the control. After quality control, the length of the sRNAs in donkey milk exosomes was mainly distributed between 18 and 22 nt, and a total of 212 miRNAs were identified, including 16 known ones and 196 new ones. Gene Ontology (GO) enrichment analysis showed that the functions of the miRNAs in donkey milk exosomes were similar to those of human milk miRNAs, such as constituting cells, organelles and other components, binding and catalytic activity and participating in the processes of cell metabolism and biological regulation. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that the miRNAs in donkey milk exosomes participated in the synthesis and secretion of aldosterone, the Hedgehog signaling pathway, mitochondrial regulation and cancer pathways.
