溶质载体家族7成员11基因SLC7A11与肝癌临床特征相关性

目的 明确溶质载体家族7成员11基因（SLC7A11）在肝癌及癌旁组织中的表达水平,了解SLC7A11基因与肝癌患者临床特征的关系。方法 收集102例肝癌患者肝癌组织及其癌旁组织,通过半定量PCR 、Real-time PCR测定SLC7A11基因在组织中的表达水平,分析该基因与肝癌患者年龄、性别、肿瘤大小、HBV感染、淋巴结转移、生存期及组织学分级的关系。结果 随机挑选20对肝癌和癌旁组织进行半定量PCR,SLC7A11基因在85.0%（17/20）的肝癌组织较癌旁组织中mRNA的表达水平明显上调。Real-time PCR检测102例肝癌和癌旁组织中SLC7A11 mRNA表达水平,72.5%（74/102）肝癌组织中SLC7A11基因表达水平明显上调（P<0.01）。在64例肝癌患者中SLC7A11 mRNA高表达组的平均生存期为16个月,低表达组的平均生存期为22个月,SLC7A11 mRNA高表达组生存期较短（P<0.01）。SLC7A11基因表达水平与肿瘤大小成正相关,肿瘤大于3 cm的肝癌患者SLC7A11基因的表达水平明显上调（P<0.05）。SLC7A11基因表达水平与患者的年龄、性别、HBV感染、淋巴结转移与否及组织学分级无关（P>0.05）。结论 SLC7A11基因在肝癌组织中表达上调,影响着肿瘤的增生及患者的生存期,提示SLC7A11基因在肝细胞癌发生发展中起着重要的作用。

Clinical characteristics correlation between solute carrier family 7 member 11 gene SLC7A11 and liver cancer

Objective To determine the expression level of SLC7A11 gene (solute carrier family 7 member 11) in liver cancer and its adjacent tissues, and to understand the relationship between SLC7A11 gene and the clinical characteristics of liver cancer patients. Methods The expression level of SLC7A11 gene in 102 liver cancer tissues and their adjacent tissues was determined by semi-quantitative PCR and real-time PCR, and the relationship between SLC7A11 gene and age, sex, tumor size, HBV infection, lymph node metastasis, survival time and histological grade of liver cancer patients was analyzed. Results Semi-quantitative PCR of SLC7A11 gene in 85.0% (17/20) liver cancer tissues was significantly up-regulated compared with that in paracancerous tissues. Real-time PCR was used to detect SLC7A11 mRNA expression in 102 liver cancer and paracancerous tissues, and SLC7A11 mRNA expression was significantly up-regulated in 72.5% (74/102) liver cancer tissues (P<0.01). The average survival time of the SLC7A11 mRNA high expression group (64 cases) was 16 months, the average survival time of the low expression group was 22 months, and the survival time of the SLC7A11 mRNA high expression group was shorter (P<0.01). SLC7A11 mRNA expression was significantly up-regulated in liver cancer patients with tumors larger than 3 cm, SLC7A11 gene expression level was positively correlated with tumor size (P<0.05), but not with age, sex, HBV infection, lymph node metastasis or histological grade (all P>0.05). Conclusion SLC7A11 expression is up-regulated in hepatocellular carcinoma, which affects tumor proliferation and survival of patients, suggesting that SLC7A11 plays an important role in the occurrence and development of hepatocellular carcinoma.
