Vibrio cholerae pathogenicity island 2 encodes two distinct types of restriction systems

Melanie Blokesch, David William Adams, Alexandre Lemopoulos, Grazia Vizzarro

In response to predation by bacteriophages and invasion by other mobile genetic elements such as plasmids, bacteria have evolved specialised defence systems that are often clustered together on genomic islands. The O1 El Tor strains of Vibrio cholerae resp ...

DNA methylation sites in early adulthood characterised by pubertal timing and development: a twin study

Markus Kirolos Youssef

Background Puberty is a highly heritable and variable trait, with environmental factors having a role in its eventual timing and development. Early and late pubertal onset are both associated with various diseases developing later in life, and epigenetic c ...

cgNA plus web : A Visual Interface to the cgNA plus Sequence-dependent Statistical Mechanics Model of Double-stranded Nucleic Acids

John Maddocks, Rahul Sharma, Alessandro Samuele Patelli

The sequence-dependent statistical mechanics of double-stranded nucleic acid, or dsNA, is believed to be essential in its biological functions. In turn, the equilibrium statistical mechanics behaviour of dsNA depends strongly both on sequence-dependent per ...

Transposable elements contribute to the spatiotemporal microRNA landscape in human brain development

Didier Trono, Evaristo Jose Planet Letschert, Shaoline Sheppard, Christopher James Playfoot

Transposable elements (TEs) contribute to the evolution of gene regulatory networks and are dynamically expressed throughout human brain development and disease. One gene regulatory mechanism influenced by TEs is the miRNA system of post-transcriptional co ...

A mitochondria-specific mutational signature of aging: increased rate of A > G substitutions on the heavy strand

Jacques Fellay, Konstantin Popadin, Dmitrii Iliushchenko, Stepan Denisov

The mutational spectrum of the mitochondrial DNA (mtDNA) does not resemble any of the known mutational signatures of the nuclear genome and variation in mtDNA mutational spectra between different organisms is still incomprehensible. Since mitochondria are ...

High throughput screening identifies SOX2 as a super pioneer factor that inhibits DNA methylation maintenance at its binding sites

Ludovica Vanzan

Binding of mammalian transcription factors (TFs) to regulatory regions is hindered by chromatin compaction and DNA methylation of their binding sites. Nevertheless, pioneer transcription factors (PFs), a distinct class of TFs, have the ability to access nu ...

m6A methylation potentiates cytosolic dsDNA recognition in a sequence-specific manner

Andrea Ablasser, Muhammet Fatih Gülen

Nucleic acid sensing through pattern recognition receptors is critical for immune recognition of microbial infections. Microbial DNA is frequently methylated at the N-6 position of adenines (m6A), a modification that is rare in mammalian host DNA. We show ...

EPD in 2020: enhanced data visualization and extension to ncRNA promoters

Giovanna Ambrosini, Philipp Bucher, René Dreos, Romain Fernand Pietro Groux, Patrick Meylan

The Eukaryotic Promoter Database (EPD), available online at https://epd.epfl.ch, provides accurate transcription start site (TSS) information for promoters of 15 model organisms plus corresponding functional genomics data that can be viewed in a genome bro ...

Requirements for DNA bubble structure for efficient cleavage by helix-two-turn-helix DNA glycosylases

Kristina Makasheva

Oxidative DNA lesions, constantly generated by both endogenous and environmentally induced reactive oxygen species, are removed via the base excision repair pathway. In bacteria, Fpg and Nei DNA glycosylases, belonging to the helix-two-turn-helix (H2TH) st ...

ZFP30 promotes adipogenesis through the KAP1-mediated activation of a retrotransposon-derived Pparg2 enhancer

Didier Trono, Bart Deplancke, Julien Léonard Duc, Julie Marie Russeil, Riccardo Dainese, Marco Cassano, Michaël Imbeault, Sunil Kumar Raghav, Petra Catalina Schwalie, Suk Min Jang, Wanze Chen, Evgeniia Pankevich

Krüppel-associated box zinc finger proteins (KZFPs) constitute the largest family of mammalian transcription factors, but most remain completely uncharacterized. While initially proposed to primarily repress transposable elements, recent reports have revea ...
