Non-coding RNAs (ncRNAs) are emerging as an important player in the regulation of genome integrity and gene expression, and they have been implicated in the pathogenesis of many diseases. The aim of the present study is to identify the repertoire of ncRNAs expressed in the developing mouse lens. We previously reported the mouse lens transcriptome, including mRNA and microRNA (miRNA) profiling at two embryonic (E15 and E18) and four postnatal (P0, P3, P6, and P9) time points. We analyzed the data from small RNA-Seq and mRNA-Seq libraries to investigate the ncRNA profile. Our analysis revealed expression of 12 different classes of ncRNA in the murine lens at six developmental time points. Annotation of small RNA data showed expression of 1,756 antisense ncRNA (asncRNA) in the mouse lens transcriptome. Likewise, we identified 82 P-element-induced wimpy testis (PIWI)-interacting RNA (piRNA), 345 transfer RNA (tRNA), 12 small nuclear RNA (snRNA), 167 small nucleolar RNA (snoRNA), 19 small Cajal body-specific RNA (scaRNA), six ribosomal RNA (rRNA), 18 tRNA-like structures, one MALAT1-associated small cytoplasmic RNA (mascRNA), one Vault RNA (vtRNA), and one Y RNA expressed in the developing mouse lens. In parallel, bioinformatic investigation of mRNA-Seq data identified expression of 1,952 long intergenic ncRNA (lincRNA) in the developing mouse lens. In conclusion, we report a comprehensive ncRNA profile in the murine lens at six developmental time points. To the best of our knowledge, this is first report investigating different classes of ncRNAs in the developing mouse lens and will be monumental in elucidating processes essential for the development of the ocular lens and the maintenance of its transparency.
