In the Huh-7.5 hepatoma cell line, replication of the genotype 1a H77 strain of hepatitis C virus (HCV) is attenuated compared to that of the genotype 1b Con1 strain. This study identifies the poorly characterized integral membrane protein, NS4B, as a major determinant for this replication difference. Chimeric H77 subgenomic replicons containing the entire NS4B gene from Con1 in place of the H7...

Hepatitis C virus (HCV) nonstructural protein 4B (NS4B), a poorly characterized integral membrane protein, is thought to function as a scaffold for replication complex assembly; however, functional interactions with the other HCV nonstructural proteins within this complex have not been defined. We report that a Con1 chimeric subgenomic replicon containing the NS4B gene from the closely related ...

Infections with hepatitis C virus (HCV) are marked by frequent viral persistence, chronic liver disease, and extraordinary viral genetic diversity. Although much has been learned about HCV since its discovery, progress has been slowed by a lack of permissive cell culture systems supporting its replication. Productive infections have been achieved recently with genotype 2a virus, but cirrhosis a...

A method was developed to localize active renin in dog kidney sections using autoradiography to detect in vitro binding of the radiolabeled renin inhibitor, 125I-H77. Light fixation by prior perfusion of the kidney with paraformaldehyde was used to immobilize renin without denaturing its binding activity. Snap frozen sections were cut on a cryostat and incubated with 125I-H77. Dry film autoradi...

Secreted infectious particles generated by the genotype 2a JFH-1 hepatitis C virus infectious clone are resistant to acidic pH, whereas intracellular virions remain acid-labile. Thus, JFH-1 particles are thought to undergo pH maturation as they are secreted from the cell. Here, we demonstrate that both infectious intracellular and secreted genotype 1a (H77)/JFH-1 chimaeric particles display enh...

The heterosis study for grain yield and its contributing characters was carried out in among 50 hybrids of pearl millet (Pennisetum glaucum (L.) R. Br.)  through Line x Tester mating design. analysis variance showed highly significant mean squares differences the all characters. due to hybrids, lines, testers line tester were also studied indicating presence considerable variability materi...

Envelope glycoprotein 2 (E2) of hepatitis C virus contains 18 conserved cysteine (Cys) residues in its ectodomain. By cysteine-alanine mutagenesis and function analysis, six Cys in H77 E2 (C494, C508, C552, C564, C607 and C644) were found to be indispensable for recognition by conformation-dependent mAb H53. Removal of any of these Cys residues did not affect E2 heterodimerization with E1, but ...

We have succeeded in constructing a stable full-length cDNA clone of strain H77 (genotype 1a) of hepatitis C virus (HCV). We devised a cassette vector with fixed 5' and 3' termini and constructed multiple full-length cDNA clones of H77 in a single step by cloning of the entire ORF, which was amplified by long reverse transcriptase-PCR, directly into this vector. The infectivity of two complete ...

Progress in understanding hepatitis C virus (HCV) biology has remained a challenge due to the lack of an efficient cell culture system for virus growth. In this study, we examined HCV core protein-mediated immortalized human hepatocytes (IHH) for growth of HCV. In vitro-transcribed full-length RNA from HCV genotype 1a (clone H77) was introduced into IHH by electroporation. Reverse transcription...
