Abstract:

Taking advantage of high-throughput sequencing technology, a large number of long noncoding RNAs (lncRNAs) have been recently characterized. Emerging evidence suggests that they play critical roles in diverse biological processes, including the differentiation of skeletal muscle cells. As previous studies have focused mainly on the polyadenylated lncRNAs, the involvement of polyA-minus lncRNAs in myocyte differentiation remains largely unexplored. To this aspect, their expression and regulation were examined in the present study. During the course of myocyte differentiation of C2C12 cells, polyA-minus RNAs were isolated and analyzed by RNA-seq. In addition to identifying 904 novel polyA-minus lncRNAs, their temporal expression was further characterized in this process. For many lncRNAs, differentiation-specific profiles were revealed. Based on their unique expression profiles, these lncRNAs were grouped into nine regulation categories. Taken together, our study greatly contributed to the identification of a dynamic regulation of polyA-minus lncRNAs, and clarified their potential roles in myocyte differentiation.
