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CMYC蛋白表达的关系。方法:应用免疫组化SP法检测PTTG、CMYC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CMYC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CMYC表达呈显著正相关。结论:提示PTTG和CMYC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 CMYC protein in human nonsmall cell lung cancer (NSCLC).Methods: Immunohistochemical methods were applied to detect the expression of PTTG,CMYCproteins in 44 surgical specimens from NSCLC patients,20 pneumonic benign lesion and 19 normal bronchial epithelium. Results:There were high erexpressions of PTTG,CMYC 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 CMYC. Conclusion: Overexpression of PTTG,CMYC may be related to human NSCLC,PTTG and CMYC play a cooperative role inthe process of NSCLC,all of them may be used as important indices for biologic behavior of NSCLC.
