Salivary CPLANE1 Levels as a Biomarker of Oral Squamous Cell Carcinoma.

BACKGROUND/AIM:This study aimed to identify novel biomarkers for oral squamous cell carcinoma (OSCC) screening to improve the survival rate of patients with oral cancer. MATERIALS AND METHODS:We investigated differential salivary gene expression in patients with OSCC, those with oral potentially malignant disorders (OPMDs), and healthy volunteers (HVs). CPLANE1 was selected for further investigation by microarray analysis. We used quantitative reverse transcription PCR (qRT-PCR) to determine CPLANE1 expression levels in the saliva. The expression of CPLANE1 in normal and oral cancer tissues was analyzed using the Gene Expression database of Normal and Tumor tissues. RESULTS:qRT-PCR analysis of saliva samples showed that CPLANE1 expression levels were significantly higher in OSCC patients than in HVs and OPMDs patients. Furthermore, we developed a screening test for OSCC using CPLANE1 and showed that it had good accuracy. CONCLUSION:Salivary CPLANE1 could be a useful biomarker for OSCC screening and early detection.
