The mechanism of HBx involved in phosphorylation of RXRα through activate JNK signaling pathway which promote the progress of HCC

Abstract

HBV病毒感染是造成肝恶性肿瘤(HCC)的重要原因之一。HBV病毒X框编码的HBx蛋白和HBV病毒的自我复制密切相关,同时已经证实在HBV感染的肝细胞癌变过程中HBx蛋白扮演着重要的角色,但是其中具体分子机理仍然不是很清楚。视黄醇能够诱导肝癌细胞的分化和凋亡,目前在临床上已经作为HCC的化疗药物而被广泛使用。研究表明,在肝癌组织中,RXRα高表达并呈现异常磷酸化修饰,这预示着肝癌的发生发展可能与RXRα的异常相关。在本文中,我们发现了HBx蛋白存在时,不管是在肝癌组织中还是在细胞水平上都出现了RXRα的磷酸化状态,且与JNK信号通路的异常激活密切相关,研究发现,HBx蛋白能够激活JNK信号通路...Persistent infection with hepatitis B virus (HBV) is a prevalent aetiology for chronic liver disease, and may lead to a premalignant condition preceding the development of hepatocellular carcinoma (HCC). HBX which is translate by the X gene is considered to play an important role in neoplastic transformation of hepatocytes in HBV-infected liver; however, the molecular mechanism of HBV-induced HCC ...学位:理学硕士院系专业:药学院_化学生物学学号:3232011115328
