摘要:目的:研究垂体瘤转化基因在非小细胞肺癌组织、肺良性病变组织和正常支气管黏膜上皮组织中的表达, 初步探讨其与非小细胞肺癌发生发展,侵袭转移的关系。方法:(1)用SP免疫组化法检测76例临床石蜡组织标本(44例非小细胞肺癌、20例肺良性病变组织和12例正常支气管黏膜上皮组织)中的PTTG蛋白的表达。(2)用RTPCR法分析PTTG mRNA在不同性质肺组织中的表达情况。〖HTH〗结果〖HTSS〗:(1)PTTG蛋白在不同性质肺组织中的表达差别具有明显差异;在TNM分期、淋巴结转移组间差别有统计学意义。(2)PTTG mRNA在不同性质肺组织中的表达差别具有明显差异(P lt;0.001);在TNM分期、淋巴结转移组间差别有统计学意义。结论：细胞肺癌的发生发展及转移有关。
Abstract: Objective: To investigate the association between PTTG expression and biological behaviors of human nonsmall cell lung cancer (NSCLC).Methods:SP immunohistochemistry was used to detect the expression of PTTG in 76 cases of paraffinembedded specimens (including 44 surgical specimens from NSCLC patients, 20 pneumonic benign lesion and 19 normal bronchial epithelium).Realtime RTPCR was performed to detect PTTGm RNA expression in 44 cases of fresh carcinoma and corresponding adjacent normal mucosa specimens.Results: The expression levels of PTTG was significantly different between normal mucosa and adenoma tissues.There were statistical relationships between their expressions and TNM stage, lymphnode metastasis. Conclusion: PTTG may play an important role in carcinogenesis、development and metastasis of human nonsmall cell lung cancer.
