OIP5 and periodontitis: However, due to the aim of this study to explore the role of lncRNA OIP5-AS1 and miR-92a-3p and the molecular mechanism underlying the regulation of lncRNA OIP5-AS1 in periodontitis by targeting miR-92a-3p, we did not investigate the signaling pathways associated with OIP5-AS1/miR-92a-3p in periodontitis.
