摘要:
It is intended to provide a modified hepatitis C virus genomic RNA having a base sequence containing the 5’-nontranslated region, core protein-encoding sequence, E1 protein-encoding sequence, p7 protein-encoding sequence, E2 protein-encoding sequence, NS2 protein-encoding sequence, NS3 protein-encoding sequence, NS4A protein-encoding sequence, NS4B protein-encoding sequence, NS5A protein-encoding sequence, NS5B protein-encoding sequence and 3’-nontransalated region of two or more hepatitis C virus genomic RNAs and having autonomous replicative competence. In particular, a modified hepatitis C virus genomic RNA which has acquired the autonomous replicative competence via the substitution of a partial RNA sequence encoding NS3 to NS4, NS5A and NS5B proteins in a hepatitis C virus genomic RNA by the partial RNA sequence encoding NS3 to NS4, NS5A and NS5B proteins of JFH1 strain represented by SEQ ID NO:1.
摘要:
The present invention provides modified hepatitis C virus genomic RNA, comprising nucleotide sequences of genomic RNA portions of two or more types of hepatitis C viruses, which comprises a 5' untranslated region, a core protein coding sequence, an E1 protein coding sequence, a p7 protein coding sequence, an E2 protein coding sequence, an NS2 protein coding sequence, an NS3 protein coding sequence, an NS4A protein coding sequence, an NS4B protein coding sequence, an NS5A protein coding sequence, an NS5B protein coding sequence, and a 3' untranslated region, and which can be autonomously replicated. In particular, the present invention relates to modified hepatitis C virus genomic RNA, which can be autonomously replicated by substitution of the RNA sequence portion encoding NS3, NS4, NS5A, and NS5B proteins of hepatitis C virus genomic RNA with a partial RNA sequence encoding NS3, NS4, NS5A, and NS5B proteins of a JFH1 strain shown in SEQ ID NO: 1.

摘要:
The present invention relates to a gene derived from a novel fulminant hepatitis C virus strain, an HCV replicon RNA with a high replication efficiency obtained using the gene, and an HCV replicon-replicating cell transfected with the replicon RNA. When the HCV replicon RNA and the HCV replicon-replicating cell of the present invention are used, HCV proteins can be continuously produced in a large amount.
