食管鳞状细胞癌组织中核干细胞因子基因mRNA的表达

目的 探讨食管鳞状细胞癌组织中核干细胞因子(NS)基因mRNA的表达水平.方法 应用实时定量PCR检测62例食管鳞状细胞癌组织及其配对正常食管黏膜组织(62例)中NS基因mRNA表达水平,分析核干细胞因子mRNA表达水平与食管鳞状细胞癌患者临床病理参数间的关系.结果 62例食管鳞状细胞癌组织中NS基因mRNA表达水平(4.5 ±2.1)高于其配对正常食管黏膜组织(2.1±1.3)表达水平(t=-5.045,P=0.000).NS基因mRNA表达水平与病理分级、浸润深度和淋巴结转移等临床参数有关(均P＜0.05),与性别、年龄、病理类型等参数无关(均P＞0.05).多元线型回归分析显示,临床病理参数在NS基因mRNA表达中起重要作用(P=0.000),NS基因mRNA的表达主要受浸润深度和淋巴结转移的影响(P＜0.05).结论 食管鳞状细胞癌的发生发展和增殖过程中NS基因mRNA起重要作用.

mRNA expression level of nucleostemin in esophageal squamous cell carcinoma tissue

OBJECTIVE: To investigate the mRNA expression levels of nucleostemin (NS) in human esophageal squamous cell carcinoma tissue. METHODS: Real-time PCR was used to quantify the mRNA expression of NS in the samples of esophageal squamous cell carcinoma tissue and their matched normal esophageal mucosa tissue from 62 patients, 36 males and 26 females, aged (61 +/- 10) (38-75). The relationship between NS mRNA expression level and clinical pathological features was analyzed. RESULTS: The NS mRNA expression level of the 62 cases of esophageal squamous cell carcinoma tissue was(4.5 +/- 2.1), significantly higher than that of the matched normal esophageal mucosa tissue [(2.1 +/- 1.3), t = -5.045, P = 0.000]. The mRNA expression level of NS was associated with tumor grade, depth of infiltration, and lymph node metastasis (all P < 0.05), but not with gender, age, and pathological type (all P > 0.05). Multiple linear regression analysis revealed that clinical and pathological features influenced the NS mRNA expression level (P = 0. 000), and the depth of infiltration and lymph node metastasis were important influencing factors for NS mRNA expression level(both P < 0.05). CONCLUSION: NS may play an important role in the progression and proliferation of esophageal squamous cell carcinoma.
