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.
口腔鳞状细胞癌(OSCC)是全球头颈部最常见的恶性肿瘤。因此,鉴定具有高诊断和治疗潜力的生物标志物对 OSCC 将具有重要的临床意义。上皮间质转化(EMT)是人类肿瘤恶性转化的关键驱动因素,包括 OSCC。失去上皮特性和获得间充质细胞特性是恶性肿瘤最重要的特征之一。尽管已经有很多关于 EMT 过程中蛋白质成分的报道,但对非蛋白质编码成分的研究相当有限。因此,我们在这里试图探讨 VIM 反义 RNA 1(VIM-AS1)在 OSCC 中的生物学意义。共有 36 名被诊断为口腔癌的患者被招募参加这项研究。从病理档案中获得患者的福尔马林固定石蜡包埋(FFPE)组织样本。用于基因表达分析,采用定量 RT-PCR。我们还分析了 E-钙粘蛋白和波形蛋白的表达水平。值得注意的是,发现在 OSCC 中,VIM-AS1 和波形蛋白的表达水平显著升高,而 E-钙粘蛋白的表达水平下调。VIM-AS1 的失调与 OSCC 患者的临床病理特征相关。ROC 分析还表明,VIM-AS1 是 OSCC 的独立诊断生物标志物。因此,我们的研究结果表明 VIM-AS1 在口腔癌中起主要作用。
