摘要

lncRNAs are a class of transcriptional RNA molecules of 200 nucleotides in length. However, the overall expression pattern and function of lncRNAs in sheep muscle is not clear. Here, we identified 1566 lncRNAs and 404 differentially expressed lncRNAs in sheep muscle from prenatal (110?days of fetus) and postnatal (2 to 3?years old of adult sheep) developmental stages by using RNA-seq technology. Several lncRNAs were identified by using RT-PCR and DNA sequencing. The expression levels of several lncRNAs were confirmed by qRT-PCR. We analyzed the effect of lncRNAs that act cis to the target genes. lncRNA targeting genes were involved in signaling pathways associated with growth and development of muscle by GO and KEGG enrichment analysis. Through our study, we provide a comprehensive expression profile of muscle lncRNAs in sheep, which provides valuable resources for further understanding genetic regulation of muscle growth and development from the perspective of lncRNA.
