摘要: 目的 探讨核糖体蛋白L29(ribosomal protein L29,RPL29)在人舌鳞状细胞癌(简称鳞癌)中的表达及意义。方法 应用免疫组织化学SP法检测52例舌鳞癌患者癌组织和癌旁组织中RPL29蛋白的表达情况。利用RNA干扰技术,将RPL29-siRNA转染到舌鳞癌CAL-27细胞中,RT-PCR法检测RPL29 mRNA的表达,蛋白质印迹法检测RPL29蛋白的表达,Transwell小室检测细胞的侵袭能力。采用 SPSS 21.0 软件包对数据进行统计学处理。结果 RPL29在舌鳞癌组织中的表达显著高于癌旁组织,RPL29蛋白表达与肿瘤有、无淋巴结转移相关(P<0.05),与患者性别、年龄、吸烟史、饮酒史、病理分级、T分期无显著相关性(P>0.05)。转染RPL29-siRNA后,舌鳞癌CAL-27细胞中RPL29表达水平下调, CAL-27细胞的侵袭能力显著下降。结论 RPL29在舌鳞癌组织中表达增高,其表达水平与患者有、无淋巴结转移之间差异显著。抑制舌鳞癌CAL-27细胞中RPL29的表达,可降低细胞体外侵袭能力。RPL29在舌鳞癌的侵袭和转移中可能发挥重要作用。

Abstract: PURPOSE: To investigate the expression and significance of ribosomal protein L29 (RPL29) in human tongue squamous cell carcinoma (TSCC). METHODS: SP method of immunohistochemistry was carried out to detect the expression of RPL29 in cancer tissues and adjacent tissues of 52 TSCC patients. CAL-27 cells were transfected with RPL29-siRNA. RPL29 protein and mRNA levels were detected using Western blot and RT-PCR. Transwell invasion assay was performed to assess the invasion ability of CAL-27 cells. SPSS 21.0 software package was used for statistical analysis. RESULTS: The expression of RPL29 in TSCC was significantly higher than that in paracancerous tissues. RPL29 over-expression was found to be associated with cervical lymph node metastasis(P<0.05),but not with age,gender,smoking history,alcohol drinking history, pathological type and T stage(P>0.05). After transfecting RPL29-siRNA into CAL-27 cells, the ability of invasion was significantly decreased. CONCLUSIONS: The expression of RPL29 in TSCC was significantly increased and its expression level was significantly different from that in patients with or without lymph node metastasis. The invasive ability of CAL-27 cells was significantly inhibited after transfection with RPL29-siRNA. RPL29 may play an important role in the processes of invasion and metastasis of TSCC.
