  • Overexpressions of PTTG and CMYC in Nonsmall Cell Lung Cancer and their Clinical Significances

    摘要:目的:探讨PTTG的表达在非小细胞肺癌发生、发展中的作用及其与CMYC蛋白表达的关系。方法:应用免疫组化SP法检测PTTG、CMYC二种蛋白在44例非小细胞肺癌、20例肺良性病变组织和12例正常支气管粘膜上皮组织中的表达。结果:PTTG和CMYC蛋白在非小细胞肺癌组织中的表达明显高于肺良性病变组及癌旁组织,在TNM分期、淋巴结转移组间差别有统计学意义。非小细胞肺癌组织中PTTG与CMYC表达呈显著正相关。结论:提示PTTG和CMYC可能参与了非小细胞肺癌的发生和发展,可作为反映其生物学行为的指标。Abstract: Objective: To investigate the expression of PTTG and its relationship with expressions of CMYC protein in human nonsmall cell lung cancer (NSCLC).Methods: Immunohistochemical methods were applied to detect the expression of PTTG,CMYCproteins in 44 surgical specimens from NSCLC patients,20 pneumonic benign lesion and 19 normal bronchial epithelium. Results:There were high erexpressions of PTTG,CMYC in NSCLC tissues than inadjacent tissues and benign lesions.There were statistical relationships between their expressions and TNM stage,lymphnode metastasis.The expression of PTTG was positively correlated with CMYC. Conclusion: Overexpression of PTTG,CMYC may be related to human NSCLC,PTTG and CMYC play a cooperative role inthe process of NSCLC,all of them may be used as important indices for biologic behavior of NSCLC.

  • Association of PTTG Expression with Biological Behaviors of Non-small Cell Lung Cancer

    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.
