Small RNA sequencing of cow's peripheral plasma exosomes


ABSTRACT: OBJECTIVE: To reveal the miRNA expression profile of placental exosomes by high-throughput sequencing and screen key biomarkers in different pregnancy period to provide new research ideas for the establishment and maintenance of pregnancy in cows and other ruminants.It can also provide reference for other pregnancy diseases. METHOD: Exosmal miRNAs were isolated from non-pregnant cows(n=3,Gestation Day(G.D.) 0),early pregnant cows(n=3,G.D.60),Middile pregnant cows(n=3,G.D.150),Late pregnant cows(n=3,G.D.240), small RNA profiles were generated by deep sequencing, in triplicate, using Illumina Hiseq SE50. RESULTS: During pregnancy, there was a high quantity of placental exosomes in the peripheral blood of cows, which selectively loaded some miRNAs. The abundance and species of miRNAs various from different stages of pregnancy, suggesting that exosomal miRNAs is involved in the regulation mechanism of pregnancy.
