Cell Type-Specific Enhancement of Hepatitis C Virus Internal Ribosome Entry Site-Directed Translation due to 5′ Nontranslated Region Substitutions Selected during Passage of Virus in Lymphoblastoid Cells

Abstract excerpt

Low-level replication of hepatitis C virus (HCV) in cultured lymphoblastoid cells inoculated with H77 serum inoculum led to the appearance of new virus variants containing identical substitutions at three sites within the viral 5' nontranslated RNA (5'NTR): G(107)-->A, C(204)-->A, and G(243)-->A (N. Nakajima, M. Hijikata, H. Yoshikura, and Y. K. Shimizu, J. Virol. 70:3325-3329, 1996). These results suggest that...
