Expression profiles of long non-coding RNAs in neurogenic bladder of spinal cord injured rats: A transcriptomic analysis


ABSTRACT: Purpose: In this study, the expression profiles of lncRNAs and mRNAs were explored in the bladder tissue of SCI rats using next-generation sequencing. Methods:Twenty female Wistar rats were randomly divided into SCI 1-3 and normal control (NC) groups. The spinal cord was completely transected at the T9-T10 level to establish the SCI model. Bladder tissues were collected on days 7, 14, and 28 after the operation. The expression profiles of lncRNAs were detected by NGS. Differentially expressed lncRNAs (DELs) were chosen for qRT-PCR verification to validate the RNA sequencing results. Results: Compared with the NC group, the SCI 1-3 groups had 468, 117, and 408 DELs (fold change (FC) > 2), including 282, 38, and 201 up-regulated and 186, 79, and 207 down-regulated lncRNAs, respectively. Likewise, 6654, 2133, and 5706 mRNAs (FC > 2) were differentially expressed between SCI 1-3 and NC rats, of which 4821, 1195, and 3695 were up-regulated, and 1833, 938, and 2011 were down-regulated, respectively. Conclusions: The results revealed the expression profiles and possible roles of lncRNAs in SCI rat NB.
