miR-126/miR-126*在肝细胞癌中的表达及其与临床预后的相关性

目的研究miR-126/miR-126*在肝细胞癌中的表达，探讨其表达与相关临床病理参数的关系。方法用RT-QPCR方法检
测74例肝细胞癌手术切除的癌组织与相应的非癌组织中miR-126/miR-126*的表达，分析其表达与相关临床病理参数的关系。
结果miR-126/miR-126*在癌组织中表达水平显著低于相对应的非癌组织；miR-126/miR-126*在肝癌中的表达呈正相关关系；
复发组癌组织中miR-126/miR-126*的表达显著低于未复发组癌组织；miR-126/miR-126*高表达组无瘤生存时间显著优于低表
达组。结论miR-126/miR-126*的的低表达可能是影响肝细胞癌转移并导致患者不良预后的一个重要因素。

Expression of miR-126/miR-126* in hepatocelluar carcinoma and its correlation with clinical outcomes

Objective To investigate the expression of miR-126/miR-126* in hepatocellular carcinoma (HCC) tissues and its
clinical significance. Methods The expressions of miR-126/miR-126* in the tumor tissues and non-cancer tissues from 74 HCC
cases were detected using real-time quantitative PCR. The correlation between miR-126/miR-126* expression and the
clinicopathological features of the patients was analyzed. Results Compared with the non-cancer tissues, HCC tissues showed
significantly lowered expression levels of miR-126/miR-126*. A positive correlation was found between the expressions of
miR-126 and miR-126* in the tumor tissues. Lower expressions of miR-126/miR-126* were significantly correlated with tumor
recurrence and poor survival of the HCC patients. Conclusion The down-regulation of miR-126/miR-126* may play an
important role in HCC metastasis and contributes to poor survival of HCC patients.
