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

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

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]
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]
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]
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]
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.
