摘要: 目的:分析线粒体拓扑异构酶Ⅰ(mitochondrial topoisomerase I,TOP1MT)与头颈鳞癌(head and neck squamous cell carcinoma,HNSCC)临床病理特征的相关性,探讨其对HNSCC顺铂耐药的影响。方法:分析83例HNSCC患者的临床病理信息,综合免疫组织化学染色和实时荧光定量PCR(qRT-PCR)结果,分析TOP1MT是否与化疗耐药等临床病理特征相关。通过体外实验,分析在顺铂作用下,TOP1MT对HNSCC细胞药物敏感性、增殖和迁移能力的影响。采用SPSS 26.0软件包对数据进行统计学分析。结果:高表达TOP1MT与HNSCC患者的肿瘤大小、临床分期、生存期、TPF方案敏感度和不良预后相关,TOP1MT高表达的患者,生存期显著低于中表达和低表达患者。体外实验表明,TOP1MT促进HNSCC细胞的顺铂耐药,在20 μmol/L顺铂作用下,过表达TOP1MT显著促进了HNSCC细胞的迁移和增殖能力。结论:TOP1MT高表达促进HNSCC恶性进展及顺铂治疗抵抗,为HNSCC的临床治疗提供了新的潜在靶点。

Abstract: PURPOSE: To analyze the correlation between mitochondrial topoisomerase I (TOP1MT) and the clinicopathological characteristics of head and neck squamous cell carcinoma(HNSCC), and to explore its impact on cisplatin resistance in HNSCC. METHODS: The correlation between TOP1MT and clinicopathological characteristics was analyzed by combining the information of 83 clinical patients with the results of immunohistochemical staining and real-time fluorescence quantitative PCR(qRT-PCR). The effect of TOP1MT on proliferation and migration of HNSCC cells with cisplatin treatment was analyzed by in vitro experiments. SPSS 26.0 software package was used for statistical analysis. RESULTS: High expressed TOP1MT was related to tumor size, clinical stage, overall survival, efficacy of TPF regimen, and worse prognosis of HNSCC patients, and the survival probability of patients with high expression of TOP1MT was significantly lower than that of patients with moderate and low expression. In vitro experiments showed that overexpression of TOP1MT significantly promoted the migration and proliferation of HNSCC cells HN30 and HN4 with 20 μmol/L cisplatin treatment. CONCLUSIONS: High expression of TOP1MT in HNSCC indicates insensitivity to chemotherapy and decreased overall survival. The experiment confirmed that TOP1MT promotes HNSCC development and may act as a potential target for clinical therapy.
