Hepatitis C virus (HCV) infection is an emerging global health concern. Combination therapy with pegylated interferon-alpha (INF alpha) and ribavirin results in approximately 60% sustained recovery. Of the non-responders, the majority are infected with genotype 1. As a consequence, improved therapeutics are necessary to enhance response rates, especially in genotype-1-infected individuals. HCV translation is mediated by an internal ribosome entry site (IRES) located within the 5' non-translated region. Recent studies have revealed that the HCV IRES recruits the cellular translation machinery in a distinct manner compared with cellular mRNA strategies. Therefore, screening assays can be developed to identify specific inhibitors of HCV translation as a possible treatment for HCV.
丙型肝炎病毒(HCV)感染是一个新出现的全球卫生问题。聚乙二醇化α干扰素(INFα)和利巴韦林联合治疗可使约60%的患者实现持续康复。在无应答者中,大多数感染的是1型基因型。因此,需要改进治疗方法以提高应答率,尤其是在感染1型基因型的个体中。HCV翻译由位于5'非翻译区内的内部核糖体进入位点(IRES)介导。最近的研究表明,与细胞mRNA策略相比,HCV IRES以一种独特的方式招募细胞翻译机制。因此,可以开发筛选试验来鉴定HCV翻译的特异性抑制剂,作为治疗HCV的一种可能方法。
