Clinical significance of Vimentin Antisense RNA 1 and its correlation with other epithelial to mesenchymal transition markers in oral cancers

Oral squamous cell carcinoma (OSCC) is the most common form of malignant tumor in the head and neck region worldwide. Hence, the identification of biological signatures with high diagnostic and therapeutic potential for OSCC will be of great clinical importance. Epithelial to mesenchymal transition (EMT) is a key driver of malignant transformation of human tumors including OSCC. Loss of epithelial properties and gain of mesenchymal cell properties is one of the most important hallmarks of malignant tumors. Although much has been reported on the protein components of the EMT process, studies on the non-protein coding components are quite limited. Consequently, here we sought to explore biological significance of VIM antisense RNA 1 (VIM-AS1) in OSCC. A total of 36 patients diagnosed with oral cancer were recruited for the study. Formalin-fixed paraffin embedded (FFPE) tissue samples of patients were obtained from pathology archive. For the gene expression analysis, quantitative RT-PCR was used. We also analyzed the expression levels of E-cadherin and Vimentin. Notably, it was found that the expression levels of VIM-AS1 and Vimentin were significantly elevated, while the expression of E-cadherin was downregulated in OSCC. Deregulation of VIM-AS1 was associated with the clinicopathological features of OSCC patients. ROC analysis also showed that VIM-AS1 is an independent diagnostic biomarker for OSCC. Consequently, our findings suggest a chief role for VIM-AS1 in oral cancers.
