A key role for hepatitis C virus NS5A serine 225 phosphorylation revealed by super-resolution microscopy [PDF]

Scientific Reports
NS5A is a multi-functional phosphoprotein that plays a key role in hepatitis C virus (HCV) genome replication and assembly. The consequences of NS5A phosphorylation for HCV biology remain largely undefined. We previously identified serine 225 (S225) as a

Hepatitis C Virus Non-Structural Protein 5A (NS5A) Disrupts Mitochondrial Dynamics and Induces Mitophagy

Cells, 2019
Mitophagy is a selective form of autophagy, targeting damaged mitochondria for lysosomal degradation. Although HCV infection has been shown to induce mitophagy, the precise underlying mechanism and the effector protein responsible remain unclear. Herein,

Hepatitis C Virus NS5A Activates Mitophagy Through Cargo Receptor and Phagophore Formation [PDF]

Pathogens
Chronic HCV infection is a risk factor for end-stage liver disease, leading to a major burden on public health. Mitophagy is a specific form of selective autophagy that eliminates mitochondria to maintain mitochondrial integrity.

Hepatitis C virus cell-cell transmission and resistance to direct-acting antiviral agents [PDF]

, 2014
Hepatitis C virus (HCV) is transmitted between hepatocytes via classical cell entry but also uses direct cell-cell transfer to infect neighboring hepatocytes.

MxB Disrupts Hepatitis C Virus NS5A–CypA Complex: Insights From a Combined Theoretical and Experimental Approach

Frontiers in Microbiology, 2022
The human myxovirus resistance B (MxB) protein is an interferon-induced restriction factor that fights a wide range of viruses. We previously demonstrated that MxB binds to hepatitis C virus (HCV)-encoded non-structural protein 5A (NS5A) and inhibits HCV

Hepatitis C virus NS5A protein promotes the lysosomal degradation of diacylglycerol O-acyltransferase 1 (DGAT1) via endosomal microautophagy

Autophagy Reports, 2022
Many viruses often use a protein degradation system (e.g., the ubiquitin-proteasome pathway or lysosome pathway) to modulate viral propagation and viral pathogenesis.

Structure-activity relationships of fluorene compounds inhibiting HCV variants [PDF]

, 2020
Approximately 71 million people suffer from hepatitis C virus (HCV) infection worldwide. Persistent HCV infection causes liver diseases such as chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma, resulting in approximately 400,000 deaths ...

Comparative Analysis of Hepatitis C Virus NS5A Dynamics and Localization in Assembly-Deficient Mutants

Pathogens, 2021
The hepatitis C virus (HCV) life cycle is a tightly regulated process, during which structural and non-structural proteins cooperate. However, the interplay between HCV proteins during genomic RNA replication and progeny virion assembly is not completely

Autophagy Induced by the N-Terminus of the Classic Swine Fever Virus Nonstructural Protein 5A Protein Promotes Viral Replication

Frontiers in Microbiology, 2021
Although classic swine fever virus (CSFV) infection has been reported to induce autophagy, the specific induced mechanism remains unrevealed. Nonstructural protein 5A (NS5A) of CSFV is a multiphosphorylated protein with multiple functions to regulate ...

Toll-like receptor 4 mediates synergism between alcohol and HCV in hepatic oncogenesis involving stem cell marker Nanog [PDF]

, 2009
Alcohol synergistically enhances the progression of liver disease and the risk for liver cancer caused by hepatitis C virus (HCV). However, the molecular mechanism of this synergy remains unclear.
