Provided are methods that facilitate the identification of host cell genes required for the replication of hepatitis C virus. Also provided are methods of identifying compounds that inhibit the activity(ies) of products of these genes required for hepatitis C virus replication in host cells, and that therefore inhibit hepatitis C virus replication in such cells. These compounds are useful as hepatitis C virus antiviral pharmaceutical agents to treat or prevent hepatitis C virus infections in humans. Also provided are novel host cell genes identified by these methods; hepatitis C virus replicons comprising both a positive and a negative selectable marker gene; and cell lines comprising said replicons.
本发明提供了有助于鉴定丙型肝炎病毒复制所需的宿主细胞
基因的方法。还提供了鉴定化合物的方法,这些化合物可抑制宿主细胞中丙型肝炎病毒复制所需的这些
