摘要: 目的:探讨甲基转移酶样蛋白5(METTL5)在口腔鳞状细胞癌(OSCC)中的表达模式、临床意义及生物学功能。方法:采用生物信息学分析和免疫组织化学染色检测METTL5在OSCC中的表达和定位,揭示METTL5表达与OSCC患者预后之间的关系。通过卡方检验评估METTL5蛋白丰度与OSCC患者临床参数之间的关系。通过CCK-8、克隆形成、划痕及Transwell实验评估Cal27细胞中METTL5沉默后细胞恶性表型的变化。结果:METTL5在OSCC中表达上调,其异常高表达与OSCC患者高病理分级(P=0.033 7),颈淋巴结转移(P=00.013 8)及低生存率显著相关(P<0.001)。体外敲低METTL5显著抑制Cal27细胞增殖、迁移和侵袭。结论:METTL5促进OSCC进展,可作为生物学标志物预测OSCC患者的预后。

Abstract: Objective:?To determine the expression pattern, clinical significance and biological function of METTL5 in oral squamous cell carcinoma (OSCC). Methods:?Bioinformatic interrogations and immunohistochemical (IHC) staining were utilized for determining the expression and localization of METTL5 in OSCC, and for revealing the relationship between METTL5 expression and prognosis in OSCC patients. The association between the abundance of METTL5 protein and clinicopathological parameters of OSCC patients were evaluated by Chi-square test. CCK-8, colony formation, wound healing and transwell assays were utilized to assess the changes in cellular malignant phenotype after METTL5 silencing in Cal27 cells. Results: METTL5 was upregulated in OSCC, and its aberrant overexpression was positively correlated with high pathological grade, cervical lymph node metastasis and reduced survival in OSCC patients (P=0.0337, 0.0138, P<0.001). METTL5 knockdown significantly inhibited proliferation, migration and invasion of Cal27 cells. Conclusions:?Our findings reveal that METTL5 promotes OSCC progression and acts as a biomarker to predict prognosis of OSCC patients.
