Salivary CCL20 Level as a Biomarker for Oral Squamous Cell Carcinoma.

ABSTRACT:

Background/aim

This study investigated the utility of C-C motif chemokine ligand 20 (CCL20) expression in saliva as a biomarker for oral squamous cell carcinoma (OSCC) and also examined the associated microbiome.

Materials and methods

The study group included patients with OSCC or oral potentially malignant disorder (OPMD), and healthy volunteers (HVs). microarray and qRT-PCR were used to compare salivary CCL20 expression levels among groups. Data on CCL20 levels in oral cancer tissues and normal tissues were retrieved from a public database and examined. Furthermore, next-generation sequencing was used to investigate the salivary microbiome.

Results

A significant increase in the expression level of CCL20 was observed in both OSCC tissues and saliva from patients with oral cancer. Fusobacterium was identified as the predominant bacteria in OSCC and correlated with CCL20 expression level. OSCC screening based on salivary CCL20 expression enabled successful differentiation between patients with OSCC and HVs.

Conclusion

CCL20 expression may be a useful biomarker for OSCC.

Project description:BackgroundNeuropilin-2 (NRP2) is a single chain transmembrane glycoprotein that acts as a co-receptor of VEGF and is related to the pathogenesis of various tumors closely. However, the clinical significance of NRP2 in oral squamous cell carcinoma (OSCC) is unclear.PurposeThe objective of this study was to investigate the role of NRP2 in the pathogenesis of OSCC and explore the associated mechanisms.Materials and methodsGEPIA (gene expression profiling interactive analysis) was used to analyze the expression of NRP2 in OSCC. Immunohistochemistry and RT-qPCR were used to detect NRP2 expression in 80 OSCC samples. The clinical correlations and prognostic significance of NRP2 expression were evaluated. In addition, the biological functions of OSCC cells transfected with shNRP2 were evaluated. The expression levels of β-catenin, C-myc, cyclin D1, and MMP-2 in Wnt/β-catenin signaling pathway were assessed by RT-qPCR after inhibiting the expression of NRP2 in SCC-25 cell line.ResultsAnalysis of cases using GEPIA revealed that NRP2 was substantially upregulated in OSCC. NRP2 expression was also significantly higher in our OSCC samples than in the controls. Elevated expression of NRP2 was correlated with lymph node metastasis (P<0.01) and distant metastasis (P<0.05) in OSCC patients, and high NRP2 levels, lymph node metastasis, and distant metastasis were associated with poor prognosis (Kaplan-Meier analysis; P<0.05). Univariate and multivariate Cox analysis showed that lymph node metastasis, distant metastasis, and NRP2 expression were independent risk factors for overall survival (OS) and disease-free survival (DFS) in OSCC patients (P<0.05). Furthermore, the proliferation, migration, and invasion of OSCC cells were inhibited by shNRP2. Following inhibiting of NRP2 expression in the SCC-25 cell line, the expression levels of β-catenin, C-myc, cyclin D1, and MMP-2 were reduced (P<0.05).ConclusionThis study shows that NRP2 functions as a tumor promoter gene in OSCC by affecting the proliferation, migration, and invasion of OSCC cells and downregulating the Wnt/β-catenin pathway. These results highlight the potential role for NRP2 as a clinical diagnostic marker.
