Involvement of Host ATR-CHK1 Pathway in Hepatitis B Virus Covalently Closed Circular DNA Formation

open access: yesmBio, 2020
The covalently closed circular (CCC) DNA of hepatitis B virus (HBV) functions as the only viral transcriptional template capable of producing all viral RNA species and is essential to initiate and sustain viral replication.

Depletion of cellular pre-replication complex factors results in increased human cytomegalovirus DNA replication.

open access: yesPLoS ONE, 2012
Although HCMV encodes many genes required for the replication of its DNA genome, no HCMV-encoded orthologue of the origin binding protein, which has been identified in other herpesviruses, has been identified.

Human DNA decays faster with time than viral dsDNA: an analysis on HPV16 using pathology archive samples spanning 85 years

open access: yesVirology Journal, 2021
Background Quality of the nucleic acids extracted from Formalin Fixed Paraffin Embedded (FFPE) samples largely depends on pre-analytic, fixation and storage conditions.

Segmenting bacterial and viral DNA sequence alignments with a trans-dimensional phylogenetic factorial hidden Markov model [PDF]

open access: yes, 2009
The traditional approach to phylogenetic inference assumes that a single phylogenetic tree can represent the relationships and divergence between the taxa. However, taxa sequences exhibit varying levels of conservation, e.g.

Neutralizing and protective monoclonal antibodies identify antigenic sites in influenza H7 hemagglutinin and select for amino acid substitutions rarely observed at the global level

open access: yesMicrobiology Spectrum
Avian influenza viruses of the H7 subtype infect a variety of avian as well as mammalian species, and a better understanding of H7 virus antigenicity and immunogenicity is vital to the development of effective countermeasures for a potential H7 pandemic ...

A DNA vaccine construct incorporating intercellular trafficking and intracellular targeting motifs effectively primes and induces memory B and T cell responses in outbred animals [PDF]

open access: yes, 2007
We developed a vaccine construct in which a BVP22 domain and an invariant-chain major histocompatibility complex class II-targeting motif capable of enhancing dendritic cell antigen uptake and presentation were fused to a sequence encoding a B- and T ...

DNA Scrunching in the Packaging of Viral Genomes [PDF]

open access: yesThe Journal of Physical Chemistry B, 2016
The motors that drive double-stranded DNA (dsDNA) genomes into viral capsids are among the strongest of all biological motors for which forces have been measured, but it is not known how they generate force. We previously proposed that the DNA is not a passive substrate but that it plays an active role in force generation. This "scrunchworm hypothesis"

Next generation sequencing for studying viruses and RNA silencing-based antiviral defense in crop plants [PDF]

open access: yes, 2014
The main objectives of this work have been to use next generation sequencing (NGS) and develop bioinformatics tools for plant virus diagnostics and genome reconstruction as well as for investigation of RNA silencing-based antiviral defense.

The 89,000-Mr murine cytomegalovirus immediate-early protein stimulates c-fos expression and cellular DNA synthesis [PDF]

open access: yes, 1988
The immediate-early (IE) genes of murine cytomegalovirus (MCMV) are expressed in the absence of prior viral protein synthesis and regulate the transcription of MCMV early genes. The effect of MCMV IE genes on growth induction was studied.

Chinese Giant Salamander Iridovirus 025L Is a Viral Essential Gene

open access: yesViruses, 2023
Ranavirus is a large nucleocytoplasmic DNA virus. Chinese giant salamander iridovirus (CGSIV) belongs to the ranavirus genus, and its replication involves a series of essential viral genes.
