The noncoding RNA linc-ADAMTS5 cooperates with RREB1 to protect from intervertebral disc degeneration through inhibiting ADAMTS5 expression.


PMID 28341660

Abstract

Previous studies have indicated the important roles of ADAMTS5 in intervertebral disc degeneration (IDD). However, the mechanisms that regulate ADAMTS5 expression in nuclear pulposus (NP) cells remain largely unknown. Evidence suggests that intergenic transcription may be associated with genes that encode transcriptional regulators. Here, we identified a long intergenic noncoding RNA, linc-ADAMTS5, which was transcribed in the opposite direction to ADAMTS5. In the present study, through mining computational algorithm programs, and publicly available data sets, we identified Ras-responsive element-binding protein 1 (RREB1) as a crucial transcription factor regulating the expression of ADAMTS5 in NP cells.
