A unique HCV RNA molecule is provided having an enhanced efficiency of establishing cell culture replication. Novel adaptive mutations have been identified within the HCV non-structural region that improves the efficiency of establishing persistently replicating HCV RNA in cell culture. This self- replicating polynucleotide molecule contains, contrary to all previous reports, a 5'-NTR that can be either an A as an alternative to the G already disclosed and therefore provides an alternative to existing systems comprising a self-replicating HCV RNA molecule. The G-->A mutation gives rise to HCV RNA molecules that, in conjunction with mutations in the HCV non-structural region, such as the G(2042)C/R mutations, possess greater efficiency of transduction and/or replication. These RNA molecules when transfected in a cell line are useful for evaluating potential inhibitors of HCV replication.

La présente invention concerne une molécule de VHC unique qui possède une efficacité améliorée pour établir une réplication de culture cellulaire. On a identifié de nouvelles mutations adaptative dans la région non structurelle du VHC qui améliorent l'efficacité de l'établissement de réplication continuelle d'ARN de VHC dans une culture cellulaire. Cette molécule polynucléotidique d'autoréplication contient, contre toutes attentes, une région non traduite 5'-NTR qui peut être aussi un A utilisé comme alternative au G déjà découvert et par conséquent il représente une alternative aux systèmes existants comprenant une molécule d'ARN de VHC. Cette mutation de G en A engendre les molécules d'ARN de VHC qui, associée à des mutations dans la région non structurelle du VH C telles que les mutations G(2042)C/R, possèdent une meilleure efficacité de transduction et/ou de réplication. Ces molécules d'ARN, lorsqu'elles sont transfectées dans une lignée cellulaire conviennent pour évaluer des inhibiteurs potentiels de la réplication du VHC.
