Annexin A1 negatively regulates viral RNA replication of hepatitis C virus.
Persistent infection with hepatitis C virus (HCV) often causes chronic hepatitis, and then shows a high rate of progression to liver cirrhosis and hepatocellular carcinoma. To clarify the mechanism of the persistent HCV infection is considered to be important for the discovery of new target(s) for the development of anti-HCV strategies.

De Novo synthesis of VP16 coordinates the exit from HSV latency in vivo [PDF]
The mechanism controlling the exit from herpes simplex virus latency (HSV) is of central importance to recurrent disease and transmission of infection, yet interactions between host and viral functions that govern this process remain unclear. The cascade

Viral and host factors regulating influenza virus replication
Avian influenza A viruses typically do not replicate very efficiently when exposed to a mammalian host species. One of the reasons for this is the low activity of the viral RNA-dependent RNA polymerase of avian influenza viruses in mammalian cells. This host restrictive effect can be overcome by adaptive mutations in the avian polymerase, many of which

A motif unique to the human DEAD-box protein DDX3 is important for nucleic acid binding, ATP hydrolysis, RNA/DNA unwinding and HIV-1 replication [PDF]
DEAD-box proteins are enzymes endowed with nucleic acid-dependent ATPase, RNA translocase and unwinding activities. The human DEAD-box protein DDX3 has been shown to play important roles in tumor proliferation and viral infections.

Host Pah1p phosphatidate phosphatase limits viral replication by regulating phospholipid synthesis
Replication of positive-strand RNA viruses [(+)RNA viruses] takes place in membrane-bound viral replication complexes (VRCs). Formation of VRCs requires virus-mediated manipulation of cellular lipid synthesis. Here, we report significantly enhanced brome mosaic virus (BMV) replication and much improved cell growth in yeast cells lacking PAH1 (pah1Δ ...

Cytomegalovirus microRNAs facilitate persistent virus infection in salivary glands. [PDF]
Micro (mi)RNAs are small non-coding RNAs that regulate the expression of their targets' messenger RNAs through both translational inhibition and regulation of target RNA stability.

Molecular biology of giant viruses' DNA replication machinery [PDF]
Viruses are the most widespread and abundant entity on this planet, further constituting the largest part of the genosphere. The majority of these infectious agents are miniature, having been described as being smaller than the smallest bacteria.

A multi-variant, viral dynamic model of genotype 1 HCV to assess the in vivo evolution of protease-inhibitor resistant variants [PDF]
Variants resistant to compounds specifically targeting HCV are observed in clinical trials. A multi-variant viral dynamic model was developed to quantify the evolution and in vivo fitness of variants in subjects dosed with monotherapy of an HCV protease ...

The lipid kinase phosphatidylinositol 4-kinase III alpha (PI4KIIIα) is an essential host factor of hepatitis C virus (HCV) replication. PI4KIIIα catalyzes the synthesis of phosphatidylinositol 4-phosphate (PI4P) accumulating in HCV replicating cells due ...

Raf‐1 kinase associates with Hepatitis C virus NS5A and regulates viral replication
Hepatitis C virus (HCV) is a positive‐strand RNA virus that frequently causes persistent infection associated with severe liver disease. HCV nonstructural protein 5A (NS5A) is essential for viral replication. Here, the kinase Raf‐1 was identified as a novel cellular binding partner of NS5A, binding to the C‐terminal domain of NS5A.
