ABSTRACT
Embryonic implantation in sows is a coordinated interaction between the implantation-competent blastocyst and receptive uterus. In addition, microRNAs are small endogenous non-coding RNAs which are involved in post-transcriptional gene regulation of several biological processes including embryonic implantation. However, the mechanisms of miRNAs involved in embryonic implantation of sows remain largely unknown. Here, we analyzed miRNAome of endometrium on day 9, 12 and 15 of pregnancy and on day 12 of non-pregnancy in Meishan and Yorkshire pigs by Illumina sequencing. From 24 libraries, we identified 312 known microRNAs and 211 potential novel miRNAs. Bioinformatics analysis showed that differentially expressed microRNAs on day 12 of pregnancy between the two breeds may play critical roles by involving "p53 signaling pathway" and "Wnt signaling pathway". Furthermore, our results demonstrated that ssc-miR-21, ssc-miR-451, ssc-miR-204, ssc-miR-199a-5p and ssc-miR-199b-5p would play crucial roles for implantation. The data generated in this study were expected to elucidate the influence of microRNAs during pre-implantation in pigs.
