PURPOSE: To analyse the relative expression and diagnostic potential of lncRNA XIST (XIST) in peri-implantitis, and explore the related mechanism of XIST in peri-implantitis.
MATERIALS AND METHODS: XIST expression in saliva of patients with peri-implantitis was detected by qRT-PCR. The diagnostic significance of XIST in peri-implantitis was assessed by ROC curve. Clinical indicators of the included patients were collected and the correlation between XIST levels and peri-implant indicators was determined by Pearson correlation analysis. Bioinformatic prediction and luciferase reporter assay confirmed the targeting relationship of XIST with downstream factors.
RESULTS: Salivary XIST levels were obviously higher in patients with peri-implantitis than in the healthy control group, and the AUC value for identifying patients was 0.8742 with a sensitivity and specificity of 83.5% and 81.4%. Patients in the peri-implantitis group had higher levels of plaque index (PLI), sulcus bleeding index (SBI) and probing depth (PD) than those in the healthy control group, and the expression of XIST was positively correlated with PLI, SBI, and PD levels. In addition, miR-150-5p was confirmed to be a potential downstream target of XIST.
CONCLUSION: XIST was overexpressed in the saliva of patients with peri-implantitis and correlated with the severity of the disease. XIST has high diagnostic significance for detecting peri-implantitis.
