Abstract

Squamous cell carcinoma of the lips and oral cavity (OSCC) contributes to 90% of the nonmelanocytic tumors of these anatomical regions. Liquid biopsy is a new, relatively noninvasive, and effective method for screening, diagnosing, and classifying tumors. Considering the role of integrin β8 subunit (ITGB8) and Myocardial infarction-associated transcript (MIAT) lncRNA in the pathogenesis and progression of different types of cancer, we aimed to evaluate the probable differences in the level of expression of these two biomarkers in control and OSCC cases and evaluate their diagnostic potential as a biomarker in tissue and liquid samples (blood and saliva) biopsy. Tissue, blood, and saliva samples from 60 participants (30 in each study group) were obtained for precise evaluation. Using extracted RNA from the samples and PCR assay, the expression level of these biomarkers was measured in control and case group samples. Parametric and nonparametric tests were equipped for the evaluation of the results. ROC analysis was done to determine the diagnostic potential of these biomarkers. Our results claimed significant differences in the level of expression of ITGB8 and MIAT-lncRNA among our study cohorts’ samples. The ROC analysis revealed the valuable potential of these factors in the diagnosis of disease in tissue and blood samples. The results of the analysis for the saliva samples suggest a satisfactory diagnostic value for ITGB8 but nonsignificant diagnostic value for the MIAT-lncRNA. ITGB8 and MIAT-lncRNA expression levels could be considered in the evaluation of suspicious oral cavity lesions, especially in the tissue and blood samples. © 2025 Elsevier B.V., All rights reserved.
