Periodontitis may modulate long-non coding RNA expression

Periodontitis is a chronic inflammatory disease that compromises the integrity of the periodontium. Despite extensive research involving periodontitis, the detailed mechanisms underlying periodontal inflammation remain unclear. However, new important expression regulators have been emerging, such as non-coding RNAs, which are important determinants in the molecular control of the inflammatory process. Taking into consideration the vital role of non-coding RNAs, we determined for the first time the expression profiles of different long non-coding RNAs (lncRNAs) that are implicated in inflammation. In this study, we take periodontal samples of healthy subjects, patients with gingivitis and with periodontitis. In both disease groups, the lncRNA OIP5-AS1 expression levels were lower than levels in healthy subjects (P < 0.05). This study reveals new insights into the relative levels of OIP5-AS1 lncRNA in healthy, gingivitis and periodontal tissue, which may have important applications as a potential biomarker with protagonist activity in the development and manifestation of destructive periodontitis.
