Abstract

Objectives: microRNAs (miRNAs) present in the gingival crevicular fluid (GCF) of patients with chronic periodontitis may serve as biomarkers of periodontal disease. The aim of this study was to perform a miRNA-sequencing study of all miRNAs present in GCF, comparing miRNA expression level profiles between advanced chronic periodontitis (CP) patients and healthy subjects (HS).

Materials and methods: GCF samples were collected from the single-rooted teeth of patients with severe CP (n = 11) and of HS (n = 12). miRNAs were isolated from GCF using an miRNeasy Serum/Plasma kit(Qiagen GmbH, Hilden, Germany). Reverse transcription polymerase chain reaction (qRT-PCR) was used to determine the expression levels of miRNA candidates involved in periodontal pathogenesis.

Results: Of all the sequenced miRNAs, miR-199, miR-146a, miR-30a, and miR-338 were identified as best representing the CP patient samples. The validation study identified miR-199 as the most powerful biomarker used to define periodontitis.

Conclusions: Upon sequencing all known miRNAs in GCF for the first time, we uncovered several potential biomarkers to define periodontitis. Identifying miRNAS in the GCF using high-throughput approaches will clarify the role of these molecules in periodontitis and provide biomarkers with potential applications.

龈沟液中的microrna:牙周炎患者差异表达的观察性病例对照研究。

目的:慢性牙周炎患者龈沟液(GCF)中存在的microRNAs (miRNAs)可能作为牙周病的生物标志物。本研究的目的是对GCF中存在的所有miRNA进行miRNA测序研究，比较晚期慢性牙周炎(CP)患者和健康受试者(HS)的miRNA表达水平。材料与方法:分别采集重度CP患者(n = 11)和HS患者(n = 12)单根牙GCF标本。使用miRNeasy血清/血浆试剂盒(Qiagen GmbH, Hilden, Germany)从GCF中分离mirna。采用逆转录聚合酶链反应(qRT-PCR)检测参与牙周发病的候选miRNA的表达水平。结果:在所有测序的mirna中，miR-199、miR-146a、miR-30a和miR-338被确定为最能代表CP患者样本的mirna。验证研究确定miR-199是用于定义牙周炎的最有效的生物标志物。结论:在首次对GCF中所有已知的mirna进行测序后，我们发现了几个潜在的生物标志物来定义牙周炎。利用高通量方法鉴定GCF中的miRNAS将阐明这些分子在牙周炎中的作用，并提供具有潜在应用价值的生物标志物。
