With 296 million cases estimated worldwide, chronic hepatitis B virus (HBV) infection is the most common risk factor for hepatocellular carcinoma (HCC). HBV-encoded oncogene X protein (HBx), a key multifunctional regulatory protein, drives viral replication and interferes with several cellular signalling pathways that drive virus-associated hepatocarcinogenesis. This review article provides a comprehensive overview of the role of HBx in modulating the various hallmarks of HCC by supporting tumour initiation, progression, invasion and metastasis. Understanding HBx-mediated dimensions of complexity in driving liver malignancies could provide the key to unlocking novel and repurposed combinatorial therapies to combat HCC.
据估计,全世界有 2.96 亿例慢性乙型肝炎病毒(HBV)感染,是肝细胞癌(HCC)最常见的危险因素。HBV 编码的癌基因 X 蛋白(HBx)是一种关键的多功能调节蛋白,它驱动病毒复制,并干扰几种细胞信号通路,从而促进与病毒相关的肝癌发生。这篇综述文章全面概述了 HBx 通过支持肿瘤起始、进展、侵袭和转移,来调节 HCC 的各种特征的作用。了解 HBx 在驱动肝恶性肿瘤方面的复杂性,可以为开发新的和重新利用的组合疗法来治疗 HCC 提供关键。
