生存素和细胞周期蛋白在非小细胞肺癌组织中的表达

目的：研究生存素（survivin）和细胞周期蛋白（cyclin）D1在非小细胞肺癌（NSCLC）组织中的表达及其生物学意义，并探讨其相关性。方法：采用免疫组化S-P法检测45例NSCLC组织中survivin和cyclin D1的表达。结果：survivin蛋白在正常肺组织中不表达，45例NSCLC组织中27例阳性表达，占60％，其表达与分化程度、临床分期、淋巴结转移密切相关，但与肿瘤组织学类型、性别、年龄无关。NSCLC组织中survivin和cyclin D1蛋白表达两者比较有显著性差异（P〈0．05）。结论：survivin基因在肺癌组织中表达上调，提示该基因与肺癌的发生、发展密切相关；survivin基因可能与cyclin D1共同在NSCLC细胞有丝分裂中起促进作用。survivin和cyclin D1可作为靶点进行肺癌靶向治疗的研究。

Expression of survivin and cyclin D1 protein in human non-small cell lung carcinoma

Objective:To research the expression of survivin and cyclin D1 in human non-small cell lung cancer, and to illustrate their relationship in NSCLC. Methods:Forty-five NSCLC paraffin embe-ded samples were collected. Survivin and cyclin D1 were tested by immunohistochemical S-P method. Results:No survivin expression was present in normal lung tissues. The positive rate of survivin in NSCLC was 60% (27/45). By statistic analysis, the significant differences were found in different pathological grading and clinical phased lymph node involvement. The patient' s gender, age and histological classification were not related with the expression of survivin. Conclusion:Survivin may play an im-portment role in the process of carcinogenesis and development of NCLC. Survivin and cyclin D1 might play synergetic roles in lung cancer cell' s karyokinesismitosis and they can be identified as potential therapeutic target in NSCLC.
