N Engl J Med:肝癌的基因表达“男女有别”

2014-12-11 MedSci MedSci原创

背景:肝癌是一种常见的,发病率男性高于女性的肝脏恶性肿瘤。有研究表明性别或与性别相关的因素可能导致宿主微环境、肝癌预后的差异。因此,我们检测细胞与肝癌患者的MicroRNA表达图谱、生存率、对α—干扰素的应答的相关性。 方法:我们收集1999年-2003年行完整肿瘤切除455患者的肝癌、癌旁组织标本(复旦大学肝癌研究所376人,香港大学医学中心79人)。分析241例患者的MicroRNA基因芯片

方法:我们收集1999年-2003年行完整肿瘤切除455患者的肝癌、癌旁组织标本(复旦大学肝癌研究所376人,香港大学医学中心79人)。分析241例患者的MicroRNA基因芯片数据,寻找与性别、生存率相关的MicroRNA,qRT-PCR分析135例病人肝癌和癌旁组织miR-26表达差异与生存率的相关性,评估79例患者(接受α—干扰素治疗39人,对照组40人)miR-26表达与α—干扰素辅助治疗的相关性。

结果:①患者临床资料:大部分患者为男性(85.1%),HBV携带者(90.5%),肝硬化(88.0%),单个肿瘤结节(84.4%),AFP升高(62.2%);②53个MicroRNA在男性与女性正常肝组织的表达有差异,只有miR-129-2在男性与女性肝癌组织的表达有差异,miR-26a-1在miR-26低表达组的正常肝组织与肝癌组织组表达有差异(P<0.001),在miR-26高表达组则没有差异(P = 0.23);③miR-26低表达组与miR-26高表达组有915个差异基因表达,915个基因中有770个基因在miR-26低表达组过表达;虽然女性比男性正常肝组织的miR-26表达升高,但是肝癌组织miR-26表达降低则与性别无相关性,miR-26低表达患者的生存率较低;④miR-26低表达患者接受α—干扰素辅助治疗后的生存率提高(P = 0.003),miR-26高表达组则对α—干扰素无应答。

结论:男性与女性肝癌患者的MicroRNA表达图谱有差异,肝癌miR-26低表达组的生存率较低,但是对α—干扰素的应答较好。
