DNA secondary structures: stability and function of G-quadruplex structures
Nature reviews genetics, 2012 In addition to the canonical double helix, DNA can fold into various other inter- and intramolecular secondary structures. Although many such structures were long thought to be in vitro artefacts, bioinformatics demonstrates that DNA sequences capable of

npj Biofilms and Microbiomes, 2021 Extracellular DNA, or eDNA, is recognised as a critical biofilm component; however, it is not understood how it forms networked matrix structures. Here, we isolate eDNA from static-culture Pseudomonas aeruginosa biofilms using ionic liquids to preserve ...

Molecules, 2013 Pyridyl polyoxazoles are 24-membered macrocyclic lactams comprised of a pyridine, four oxazoles and a phenyl ring. A derivative having a 2-(dimethylamino)ethyl chain attached to the 5-position of the phenyl ring was recently identified as a selective G ...

Re-evaluation of G-quadruplex propensity with G4Hunter
Nucleic Acids Research, 2016 Critical evidence for the biological relevance of G-quadruplexes (G4) has recently been obtained in seminal studies performed in a variety of organisms.

Crucial Role of the C-Terminal Domain of Hfq Protein in Genomic Instability
Microorganisms, 2020 G-rich DNA repeats that can form G-quadruplex structures are prevalent in bacterial genomes and are frequently associated with regulatory regions of genes involved in virulence, antigenic variation, and antibiotic resistance.

GNG Motifs Can Replace a GGG Stretch during G-Quadruplex Formation in a Context Dependent Manner. [PDF]
PLoS ONE, 2016 G-quadruplexes are one of the most commonly studied non-B DNA structures. Generally, these structures are formed using a minimum of 4, three guanine tracts, with connecting loops ranging from one to seven. Recent studies have reported deviation from this

Replication of G Quadruplex DNA [PDF]
Genes, 2019 A cursory look at any textbook image of DNA replication might suggest that the complex machine that is the replisome runs smoothly along the chromosomal DNA. However, many DNA sequences can adopt non-B form secondary structures and these have the potential to impede progression of the replisome.

Electrochemical and AFM Characterization of G-Quadruplex Electrochemical Biosensors and Applications
Journal of Nucleic Acids, 2018 Guanine-rich DNA sequences are able to form G-quadruplexes, being involved in important biological processes and representing smart self-assembling nanomaterials that are increasingly used in DNA nanotechnology and biosensor technology.

Multimerization rules for G-quadruplexes [PDF]
Nucleic Acids Research, 2017 G-quadruplexes can multimerize under certain conditions, but the sequence requirements of such structures are not well understood. In this study, we investigated the ability of all possible variants of the central tetrad in a monomeric, parallel-strand G-quadruplex to form higher-order structures.

CX-5461 is a DNA G-quadruplex stabilizer with selective lethality in BRCA1/2 deficient tumours
Nature Communications, 2017 G-quadruplex DNAs form four-stranded helical structures and are proposed to play key roles in different cellular processes. Targeting G-quadruplex DNAs for cancer treatment is a very promising prospect.
