Subtype-Specific Prevalence of Hepatitis C Virus NS5A Resistance Associated Substitutions in Mainland China

open access: yesFrontiers in Microbiology, 2019
Resistance associated substitutions (RASs) can reduce the efficacy of direct-acting antiviral agents (DAAs) targeting hepatitis C virus (HCV) and lead to treatment failure.

Desirable Characteristics of Hepatitis C Treatment Regimens: A Review of What We Have and What We Need. [PDF]

open access: yes, 2016
There have been dramatic advancements in the treatment of chronic hepatitis C (HCV) infection. This is largely due to the approval of several direct-acting antiviral agents (DAAs) from a variety of medication classes with novel mechanisms of action ...

HCV NS5A protein containing potential ligands for both Src homology 2 and 3 domains enhances autophosphorylation of Src family kinase Fyn in B cells.

open access: yesPLoS ONE, 2012
Hepatitis C virus (HCV) infects B lymphocytes and induces mixed cryoglobulinemia and B cell non-Hodgkin's lymphoma. The molecular mechanism for the pathogenesis of HCV infection-mediated B cell disorders remains obscure. To identify the possible role for

Dominant negative effect of wild-type NS5A on NS5A-adapted subgenomic hepatitis C virus RNA replicon

open access: yesJournal of General Virology, 2004
An efficient model is currently used to study hepatitis C virus (HCV) replication in cell culture. It involves transfection in Huh7, a hepatoma-derived cell line, of an antibiotic (neomycin) selectable HCV subgenomic replicon encoding the non-structural (NS) proteins from NS3 to NS5B.

Phosphorylation of the hepatitis C virus NS5A protein in vitro and in vivo: properties of the NS5A-associated kinase [PDF]

open access: yesJournal of Virology, 1997
NS5A derived from a hepatitis C virus (HCV) genotype 1b isolate has previously been shown to undergo phosphorylation on serine residues (T. Kaneko, Y. Tanji, S. Satoh, M. Hijikata, S. Asabe, K. Kimura, and K. Shimotohno, Biochem. Biophys. Res. Commun. 205:320-326, 1994).

Analysis of genetic polymorphisms and drug resistance mutations in the NS5 region of HCV genome (Flasuviricetes: Amarillovirales: Flaviviridae: Hepacivirus C) in samples obtained in 2022–2023 from HIV-infected treatment-naive residents of Altai Krai

open access: yesВопросы вирусологии
Introduction. Altai Krai is a region with an unfavorable situation of HIV-1 and HCV infection, as well as HIV-1 and HCV coinfection. Due to this, it is necessary to study the HCV genetic variants and their drug resistance (DR) to direct-acting antivirals

Drug Resistance Profile and Clinical Features for Hepatitis C Patients Experiencing DAA Failure in Taiwan

open access: yesViruses, 2021
About 4% of the population in Taiwan are seropositive for anti-HCV Ab and 70% with HCV RNA. To address this high chronic hepatitis C disease load, Taiwan National Health Insurance started reimbursing genotype-specific DAAs in 2017 and pangenotype DAAs in

Exotic Branes and Nonperturbative Seven Branes [PDF]

open access: yes, 1999
We construct the effective action of certain exotic branes in the Type II theories which are not predicted by their spacetime supersymmetry algebras. We analyze in detail the case of the NS-7B brane, S-dual to the D7-brane, and connected by T-duality to ...

eEF1A Interacts with the NS5A Protein and Inhibits the Growth of Classical Swine Fever Virus

open access: yesViruses, 2015
The NS5A protein of classical swine fever virus (CSFV) is involved in the RNA synthesis and viral replication. However, the NS5A-interacting cellular proteins engaged in the CSFV replication are poorly defined.

Hepatitis C Virus and Hepatocellular Carcinoma: Pathogenetic Mechanisms and Impact of Direct-Acting Antivirals [PDF]

open access: yes, 2018
INTRODUCTION: Globally, between 64 and 103 million people are chronically infected with Hepatitis C virus (HCV), with more than 4.6 million people in the United States and is associated with more than 15.000 deaths annually.
