Zinc Mesoporphyrin Induces Rapid Proteasomal Degradation of Hepatitis C Nonstructural 5A Protein in Human Hepatoma Cells

open access: yes, 2010
The nonstructural 5A (NS5A) protein of hepatitis C virus (HCV), plays a critical role in HCV replication and is an attractive target for the therapy of HCV infection. So far, little is known about the post-translational regulation of NS5A protein and its

Active RNA replication of hepatitis C virus downregulates CD81 expression. [PDF]

open access: yesPLoS ONE, 2013
So far how hepatitis C virus (HCV) replication modulates subsequent virus growth and propagation still remains largely unknown. Here we determine the impact of HCV replication status on the consequential virus growth by comparing normal and high levels ...

Addition of ribavirin to daclatasvir plus asunaprevir for chronic hepatitis C 1b patients with baseline NS5A resistance-associated variants improved response

open access: yesJournal of the Formosan Medical Association, 2017
Daclatasvir is a nonstructural protein 5A inhibitor with potent activity against hepatitis C virus genotypes 1–6 in vitro, and asunaprevir is a nonstructural protein 3 protease inhibitor with activity against genotypes 1, 4, 5, and 6.

Hepatitis C Virus Nonstructural Protein 5A Contains Potential Transcriptional Activator Domains

open access: yesMolecules and Cells, 1997
Hepatitis C virus (HCV), a major etiologic agent of transfusion associated hepatitis, is a positive, single-stranded RNA virus and is also known to be implicated in liver cirrhosis and hepatocellular carcinoma. Nonstructural protein 5A (NS5A) of HCV contains acidic and proline-rich amino acids in its carboxy-terminal half.

A quantitative high-resolution genetic profile rapidly identifies sequence determinants of hepatitis C viral fitness and drug sensitivity.

open access: yesPLoS Pathogens, 2014
Widely used chemical genetic screens have greatly facilitated the identification of many antiviral agents. However, the regions of interaction and inhibitory mechanisms of many therapeutic candidates have yet to be elucidated.

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

open access: yesAdvanced Science, EarlyView.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Function of nonstructural 5A protein of genotype 2a in replication and infection of HCV with gene substitution

open access: yesWorld Journal of Gastroenterology, 2011
To explore the function of Nonstructural 5A (NS5A) protein of genotype 2a (JFH1) in the replication and infection of hepatitis C virus (HCV).Intergenotypic chimera FL-J6JFH/J4NS5A was constructed by inserting NS5A gene from 1b stain HC-J4 by the overlapping polymerase chain reaction (PCR) method and the restriction enzyme reaction.

Understanding the Interaction Determinants of CAPN1 Inhibition by CAST4 from Bovines Using Molecular Modeling Techniques

open access: yesMolecules, 2014
HCV-induced CAPN activation and its effects on virus-infected cells in a host-immune system have been studied recently. It has been shown that the HCV-nonstructural 5A protein acts as both an inducer and a substrate for host CAPN protease; it ...

Rational Design of Broad‐Spectrum Anti‐Enteroviral Molecular Glues Targeting Enteroviral RNAi Suppressors

open access: yesAdvanced Science, EarlyView.
By leveraging this homodimerization mechanism, molecular glues were rationally designed to induce dysfunctional 3A dimerization, thereby restoring antiviral RNAi. The optimal molecular glue, VTP‐32, demonstrated potent and pan‐enterovirus (groups A, B, D) antiviral effects.

An integrated analysis of elbasvir/grazoprevir in Korean patients with hepatitis C virus genotype 1b infection [PDF]

open access: yesClinical and Molecular Hepatology, 2019
Background/Aims In the Republic of Korea, an estimated 231,000 individuals have chronic hepatitis C virus (HCV) infection. The aim of the present analysis was to evaluate the safety and efficacy of elbasvir/grazoprevir (EBR/GZR) administered for 12 weeks
