Oncotarget:脑组织表达的X连锁蛋白2的上调对乙肝病毒X蛋白诱导肝癌发生至关重要

2017-08-10 MedSci MedSci原创

肝细胞癌(HCC)是全球第三大癌症相关死亡原因。慢性乙型肝炎病毒(HBV)感染是HCC的主要原因。X蛋白(HBx)是由HBV基因组编码的四种蛋白质之一,在HBV诱导的HCC的发病机制中起着至关重要的作用。然而,HBx触发HCC的分子机制仍然尚未确定。

肝细胞癌(HCC)是全球第三大癌症相关死亡原因。慢性乙型肝炎病毒(HBV)感染是HCC的主要原因。X蛋白(HBx)是由HBV基因组编码的四种蛋白质之一,在HBV诱导的HCC的发病机制中起着至关重要的作用。然而,HBx触发HCC的分子机制仍然尚未确定。

我国的研究者们:发现HBV转基因小鼠和人类HCC标本肝组织中脑组织表达的X连锁蛋白2(BEX2)和骨桥蛋白(OPN)的表达升高。此外,HBV感染HCC患者样本中BEX2和OPN的表达呈正相关。与HBV阴性HCC标本相比,HBV阳性HCC标本中BEX2和OPN的蛋白水平均较高。 HBx通过上调BEX2增强OPN表达。重要的是,BEX2的消耗抑制了高表达HBx的HCC细胞的致瘤性。

研究证实了BEX2在HCC发病机制中的重要作用,BEX2可能是HBV相关的HCC患者的新型治疗靶点。HBx/BEX2/OPN信号盒参与了HBV诱导的HCC的发病机制。
