To investigate the role of transglutaminase 3 (TGM3) gene in human esophageal squamous cell carcinoma (ESCC), and analyze its relationship with clinicopathological parameters.
Gene expression of TGM3 in fresh esophageal cancer tissues and their corresponding normal mucosas was detected immunohistochemically (IHC) by means of tissue microarray (TMA). Its correlation with clinical characteristics was evaluated and analyzed by univariate analysis. All statistical analyses were performed by SPSS version 10.0.
Expression rate of TGM3 was reduced to 81.8% in ESCC. Expression of TGM3 was significantly inversely correlated with histological grade of esophageal carcinoma (in grade I, II and III tumors, the reduced expression was 4/7, 57/71, and 20/21, respectively, P < 0.05), whereas it had no obvious correlations with lymph node metastasis and depth of invasion.
Reduced expression of TGM3 may play an important role in esophageal carcinogenesis.
探讨转谷氨酰胺酶3(TGM3)基因在人食管鳞状细胞癌(ESCC)中的作用,并分析其与临床病理参数的关系。
采用组织芯片(TMA)免疫组织化学(IHC)方法检测新鲜食管癌组织及其相应正常黏膜中TGM3的基因表达。通过单因素分析评估并分析其与临床特征的相关性。所有统计分析均使用SPSS 10.0版软件进行。
ESCC中TGM3的表达率降至81.8%。TGM3的表达与食管癌的组织学分级呈显著负相关(在I级、II级和III级肿瘤中,表达降低分别为4/7、57/71和20/21,P < 0.05),而与淋巴结转移和浸润深度无明显相关性。
TGM3表达降低可能在食管癌发生中起重要作用。
