摘要: 目的:研究HOTAIR在舌鳞状细胞癌中的表达,并探究HOTAIR与舌鳞状细胞癌淋巴结转移的关系。方法:对19例舌鳞状细胞癌患者的癌组织以及其对应的19例癌旁组织进行实时荧光定量PCR检测,检测HOTAIR在癌组织、癌旁组织的相对表达量,把结果与患者的TNM分期进行关联比较,并进一步通过构建沉默HOTAIR表达的CAL27、SCC9细胞系,检测肿瘤细胞侵袭、迁移能力的改变。结果:19对舌鳞状细胞癌组织中,26.3%显示出HOTAI的高表达(P=0.016 9<0.05),且高表达者均为具有淋巴结转移的患者,而在无淋巴结转移的癌组织中HOTAIR呈现低表达(P<0.001),通过RNA干扰技术降低HOTAIR在CAL27及SCC9细胞系中的表达水平,结果发现细胞侵袭(P<0.001)和迁移能力(P<0.001)受到了抑制。结论:长链非编码RNA HOTAIR在舌鳞状细胞癌淋巴结转移过程中可能发挥促进因子的作用。

Abstract: Objective: To investigate the correlation between Hox transcript anti-sense intergenic RNA (HOTAIR) and lymph node metastasis in tongue squamous cell carcinoma (TSCC). Methods: The expression of HOTAIR was detected in 19 TSCC tissues and 19 matched nonmalignant tissues by using Real-time quantitative PCR, and its correlation with TNM stage was analyzed. The migration and invasion abilities were evaluated in CAL27 and SCC9 cell lines after silencing the expression of HOTAIR. Results: 26.3% of TSCC tissues showed a higher expression of HOTAIR compared to the matched nonmalignant tissues (P=0.0169), and all these patients underwent lymphatic metastasis. Patients without lymphatic metastasis showed a low expression of HOTAIR (P<0.001). After silencing the expression of HOTAIR, the tumor cells' ability of migration and invasion was decreased (P<0.001). Conclusion: High expression of HOTAIR may be an indicator of lymphatic metastasis in TSCC.
