Non-coding RNAs have been shown to play vital roles in muscle development. However, the biological roles of long non-coding natural antisense transcripts, antisense lncRNAs (ASlncRNAs), are largely unknown in embryonic muscle development. Here, we identified a total of 466 ASlncRNAs in the longissimus dorsi muscle. And 48 differentially expressed ASlncRNAs were identified based on pairwise comparisons (P < 0.05), sixteen of which were validated by qPCR. Additionally, 466 ASlncRNAs were predicted to target 335 protein coding genes based on complementary base-pairing. Enrichment analysis suggests that ASlncRNAs may be involved in muscle development by negatively regulating the expression of target genes. Furthermore, 170 ASlncRNAs were identified as potential miRNA precursors, suggesting that these ASlncRNAs may be involved in the regulation of muscle development by producing miRNA precursors. Our results provide a catalog of goat muscle-related ASlncRNAs, and will contribute to a fuller understanding of the roles of ASlncRNAs in muscle development. • RNA-seq reveals natural antisense lncRNAs involved in embryonic muscle development of goat, and 48 differentially expressed ASlncRNAs were identified. • Functional analysis suggests that ASlncRNAs may be involved in skeletal muscle development by negatively regulating the expression of target genes and producing miRNA precursors.
