人PTN基因在脑胶质瘤、肝细胞癌、喉鳞癌中的表达研究

Expression of PTN gene in glioma, hepatoma and laryngeal squamous cell carcinoma

目的 :运用基因表达谱芯片和原位杂交技术观察人 PTN(pleiotrophin)基因在某些恶性肿瘤中的表达 ,并探讨其在肿瘤发生发展中的作用。 方法 :用 Bio Door 40 96型 c DNA基因表达谱芯片和原位杂交技术检测 PTN基因在 5例脑胶质瘤、10例喉鳞癌、6例肝细胞癌及正常对照组织中的表达水平。 结果 :在上述肿瘤的基因表达谱芯片检测中 ,PTN基因表达均显著增高 ,与脑胶质瘤、喉鳞癌、肝细胞癌的原位杂交检测结果相吻合。 结论 :c DNA基因表达谱芯片能够为恶性肿瘤的相关基因功能分析提供特异和可靠的数据。 PTN基因在恶性肿瘤的发生机制中可能起重要作用。

Objective:To investigate the role of pleiotrophin (PTN) gene in carcino genesis using cDNA microarray and in situ hybridization. Methods:The expression of PTN gene in 5 cases of glioma, 10 laryngeal squamous cell carcinoma, 6 cases of hepatocarcinoma, and normal controls were detected by BioDoor 4096 type cDNA microarray and in situ hybridization. Results: The expression of PTN gene in carcinoma samples were significantly higher than in normal controls by cDNA microarray, the results was the same as by in situ hybridization. Conclusion: cDNA microarray is an effective technique in analysis of functional study of associated genes in carcinoma. High expression of PTN gene might be correlated with mechanism of multiple carcinoma. [
