Cadherin EGF LAG seven pass G-type receptor 3 (CELSR3) contributes to cell contact-mediated communication. Dysregulation of promoter  methylation has been reported in various cancers. Objectives: The objectives of this study were to investigate the CELSR3 hypermethylation level in oral squamous cell carcinomas (OSCCs) using methylation-sensitive high-resolution melting analysis (MS-HRM) and to correlate CELSR3 methylation with patient demographic and clinicopathological parameters. Materials and Methods: Frozen tissue samples of healthy subjects’ normal mucosa and OSCCs were examined with regard to their methylation levels of the CELSR3 gene using MS-HRM. Results: MS-HRM analysis revealed a high methylation level of CELSR3 in 86% of OSCC cases. Significant correlations were found between CELSR3 quantitative methylation levels with patient ethnicity (P=0.005), age (P=0.024) and pathological stages (P=0.004). A moderate positive correlation between CELSR3 and patient age was also evident (R=0.444, P=0.001). Conclusions: CELSR3 promoter hypermethylation may be an important mechanism involved in oral carcinogenesis. It may thus be used as a biomarker in OSCC prognostication.}, keywords = {CELSR3,hypermethylation,oral squamous cell carcinoma,Biomarker}, url = {https://journal.waocp.org/article_31830.html}, eprint = {https://journal.waocp.org/article_31830_4fb553b8e3c350e98af90cff77e62cb0.pdf} }
