Open-source genomic analysis of Shiga-toxin–producing E. coli O104:H4 [PDF]

open access: yes, 2011
An outbreak caused by Shiga-toxin–producing Escherichia coli O104:H4 occurred in Germany in May and June of 2011, with more than 3000 persons infected. Here, we report a cluster of cases associated with a single family and describe an open-source genomic

Attachment site recognition and regulation of directionality by the serine integrases [PDF]

open access: yesNucleic Acids Research, 2013
Abstract Serine integrases catalyze the integration of bacteriophage DNA into a host genome by site-specific recombination between ‘attachment sites’ in the phage ( attP ) and the host ( attB ). The reaction is highly directional; the reverse excision reaction between the product attL and attR sites does not occur in the absence of a ...

SHIELD: a platform for high-throughput screening of barrier-type DNA elements in human cells

open access: yesNature Communications, 2023
Chromatin boundary elements contribute to the partitioning of mammalian genomes into topological domains to regulate gene expression. Certain boundary elements are adopted as DNA insulators for safe and stable transgene expression in mammalian cells ...

Anti-phage islands force their target phage to directly mediate island excision and spread. [PDF]

open access: yes, 2018
Vibrio cholerae, the causative agent of the diarrheal disease cholera, is antagonized by the lytic phage ICP1 in the aquatic environment and in human hosts. Mobile genetic elements called PLEs (phage-inducible chromosomal island-like elements) protect V.

Gated rotation mechanism of site-specific recombination by ϕC31 integrase [PDF]

open access: yes, 2012
Integrases, such as that of the Streptomyces temperate bacteriophage ϕC31, promote site-specific recombination between DNA sequences in the bacteriophage and bacterial genomes to integrate or excise the phage DNA.

Streptococcus pneumoniae: a Plethora of Temperate Bacteriophages With a Role in Host Genome Rearrangement

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Bacteriophages (phages) are viruses that infect bacteria. They are the most abundant biological entity on Earth (current estimates suggest there to be perhaps 1031 particles) and are found nearly everywhere.

The mechanism of ϕC31 integrase directionality : experimental analysis and computational modelling [PDF]

open access: yes, 2016
Serine integrases, DNA site-specific recombinases used by bacteriophages for integration and excision of their DNA to and from their host genomes, are increasingly being used as tools for programmed rearrangements of DNA molecules for biotechnology and ...

Genome integration and excision by a new Streptomyces bacteriophage, ϕJoe [PDF]

open access: yes, 2017
Bacteriophages are the source of many valuable tools for molecular biology and genetic manipulation. In Streptomyces, most DNA cloning vectors are based on serine integrase site-specific DNA recombination systems derived from phage.

Critical involvement of the ATM-dependent DNA damage response in the apoptotic demise of HIV-1-elicited syncytia. [PDF]

open access: yesPLoS ONE, 2008
DNA damage can activate the oncosuppressor protein ataxia telangiectasia mutated (ATM), which phosphorylates the histone H2AX within characteristic DNA damage foci.

Targeting STAT3 in Cancer with Nucleotide Therapeutics. [PDF]

open access: yes, 2019
Signal transducer and activator of transcription 3 (STAT3) plays a critical role in promoting the proliferation and survival of tumor cells. As a ubiquitously-expressed transcription factor, STAT3 has commonly been considered an "undruggable" target for ...
