The roles of long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs) in embryonic development remain unclear. We performed a comprehensive analysis of lncRNA and circRNA profiles in rabbit embryos at different stages by whole transcriptome sequencing. We identified 719 lncRNAs and 744 circRNAs that were differentially expressed between stages S1, S2 and S3. A total of 241 differentially expressed lncRNAs and 166 differentially expressed circRNAs were significantly involved in embryonic morphogenesis and development. An RNA network was established and of the embryonic development-associated RNAs, the lncRNAs TCONS_00009253 and TCONS_00010436 were persistently downregulated, while circRNA_07129, circRNA_15209, and circRNA_12526 were persistently upregulated, and their co-expressed mRNAs TBX1, WNT3 and FGFR2 were persistently downregulated during embryonic development. These candidate RNAs were mainly involved in the Wnt, PI3K-Akt, and calcium signaling pathways. This study reports candidate lncRNAs and circRNAs that may be indispensable for the morphogenesis and development of rabbit embryos.
