Abstract

Hepatitis C virus (HCV) is one of the most prevalent pathogens which causes significant morbidity and mortality in 2% of the world's population. Several interferon-stimulated genes (ISGs) are involved in HCV clearance by interacting with the viral proteins. Among these ISGs, the tripartite motif (TRIM) family genes are elevated during HCV infection. This study aims to evaluate the expression of three TRIM family genes in chronic hepatitis C patients, distributed among different groups, including TRIM11, TRIM14, and TRIM25. A total of 242 participants were recruited in this study, including 182 infected patients, 37 naïve individuals, and 23 control individuals. Out of 182 infected patients, 100 achieved sustained virologic response (SVR), 61 achieved rapid virologic response (RVR), and 21 patients developed hepatocellular carcinoma (HCC), showing no response to the given treatments. Our results indicate highest expression levels of TRIM mRNA transcripts in the RVR group with the highest increase of 7.5 folds in TRIM25, 6.68 folds in TRIM14, followed by the data from patients of the SVR group. The elevation was also evident in other groups, i.e., SVR and HCC, in different patterns among all the three TRIM genes. In addition to elevation in expression levels, a linear correlation is observed between the TRIM mRNAs and viral loads of HCV. These results showed the potential role of TRIM family genes in HCV restriction.

摘要

丙型肝炎病毒(HCV)是世界上2%的人口中导致显著发病率和死亡率的最普遍病原体之一。几种干扰素刺激基因(ISG)通过与病毒蛋白相互作用参与HCV清除。在这些ISG中,三方基序(TRIM)家族基因在HCV感染期间升高。本研究旨在评估慢性丙型肝炎患者中三个TRIM家族基因的表达,这些患者分布在不同组中,包括TRIM11、TRIM14和TRIM25。本研究共招募了242名参与者,包括182名感染患者、37名未感染个体和23名对照个体。在182名感染患者中,100名实现了持续病毒学应答(SVR),61名实现了快速病毒学应答(RVR),21名患者发展为肝细胞癌(HCC),对给定治疗无反应。我们的结果表明,RVR组中TRIM mRNA转录本的表达水平最高,其中TRIM25增加了7.5倍,TRIM14增加了6.68倍,其次是SVR组患者的数据。在其他组中,即SVR和HCC组,所有三个TRIM基因也以不同模式出现了这种升高。除了表达水平升高外,还观察到TRIM mRNA与HCV病毒载量之间存在线性相关性。这些结果表明了TRIM家族基因在限制HCV方面的潜在作用。
