摘要: 目的:评价LASP1 对口腔鳞癌细胞增殖、转移、侵袭和周期的影响,并对3种抗肿瘤药物顺铂、阿帕替尼和多西他赛的相关作用进行分析。方法:利用The human protein atlas数据分析LASP1与头颈部肿瘤生存率、预后的关系。RT-PCR 和Western免疫印迹检测LASP1在口腔鳞癌细胞系的mRNA和蛋白表达。慢病毒构建LASP1沉默的HN30稳转细胞株,CCK-8 法检测细胞增殖,平板克隆实验检测细胞克隆形成能力,Transwell法检测细胞转移和侵袭能力,流式细胞仪检测细胞周期变化。建立裸鼠口腔鳞癌肺部转移瘤。CCK-8法分析3种药物顺铂、阿帕替尼和多西他赛在细胞中的IC50变化。采用SPSS 11.0 软件包对数据进行统计学分析。结果:LASP1与头颈部肿瘤生存率、预后密切相关。LASP1促进口腔鳞癌细胞系HN30增殖、克隆形成、转移和侵袭,促进细胞周期G2/M期过渡。沉默LASP1后,裸鼠肺部转移瘤显著减少,多西他赛IC50显著下调,而顺铂和阿帕替尼IC50无显著变化。结论:LASP1促进口腔鳞癌细胞增殖、平板克隆、转移和侵袭,细胞周期G2/M期过渡,促进裸鼠体内肺转移瘤形成和多西他赛耐药。

Abstract: PURPOSE: This study was designed to investigate the effects of LASP1 on proliferation, metastasis, invasion, and cycle of oral squamous cell carcinoma cells and analyze the changes of IC50 in three antitumor drugs: cisplatin, apatinib and docetaxel. METHODS: The correlation between LASP1 and survival rate and prognosis of patients with head and neck cancer were analyzed on the human protein atlas data. RT-PCR and Western blot were used to detect mRNA and protein expression of LASP1 in oral squamous cell carcinoma cell lines. LASP1 silenced HN30 stable transfectant cell line was constructed by lentivirus. CCK-8 assay was used to detect cell proliferation. Plate colony assay was used to detect cell clone formation ability. Transwell assay was used to detect cell migration and invasion ability. Flow cytometry was used to detect cell cycle changes. Oral squamous cell carcinoma metastases were established in nude mouse, the number of metastatic lung nodules was counted and stained with H-E. CCK-8 method was used to analyze the changes of IC50 in three antitumor drugs: cisplatin, apatinib and docetaxel. Statistical analysis was performed using SPSS 11.0 software package. RESULTS: LASP1 was closely related to the survival rate and prognosis of head and neck cancer. LASP1 promoted proliferation, colony formation, metastasis and invasion of oral squamous cell carcinoma cell line HN30, promoted G2/M phase transition of cell cycle, and significantly reduced the formation of lung metastasis in nude mice after silencing. There was significant correlation with docetaxel IC50 but no significant impact on cisplatin IC50 and aptatinib IC50. CONCLUSIONS: LASP1 enhances cell proliferation, plate cloning, metastasis and invasion, G2/M phase transition of cell cycle, promotes lung metastasis in nude mice and docetaxel resistance of oral squamous cell carcinoma cell line HN30.
