Polyelectrolyte effects in G-quadruplexes [PDF]
Biophysical Chemistry, 2013 The role of counterion condensation as a dominant force governing the stability of DNA duplexes and triplexes is well established. In contrast, the effect of counterion condensation on the stability of G-quadrupex conformations is poorly understood. Unlike other ordered nucleic acid structures, G-quadruplexes exhibit a specific binding of counterions ...

G-Quadruplex Structures and G-Quadruplex-Interactive Compounds [PDF]
, 2011 G-quadruplexes are noncanonical secondary structures formed in DNA sequences containing consecutive runs of guanines. DNA G-quadruplexes have recently emerged as attractive cancer therapeutic targets. It has been shown that the 3' G-rich single-stranded overhangs of human telomeres can form G-quadruplex structures.

Aminoglycosylation can enhance the G-quadruplex binding activity of epigallocatechin. [PDF]
PLoS ONE, 2013 With the aim of enhancing G-quadruplex binding activity, two new glucosaminosides (16, 18) of penta-methylated epigallocatechin were synthesized by chemical glycosylation.

Quantitative Visualization of DNA G-quadruplex Structures in Human Cells
Nature Chemistry, 2013 Four-stranded G-quadruplex nucleic acid structures have been of great interest as their high thermodynamic stability under near-physiological conditions suggests that they could form in cells.

G-quadruplexes and G-quadruplex ligands: targets and tools in antiviral therapy [PDF]
Nucleic Acids Research, 2018 G-quadruplexes (G4s) are non-canonical nucleic acids secondary structures that form within guanine-rich strands of regulatory genomic regions. G4s have been extensively described in the human genome, especially in telomeres and oncogene promoters; in recent years the presence of G4s in viruses has attracted increasing interest.

G-quadruplexes in helminth parasites
Nucleic Acids Research, 2022 Abstract Parasitic helminths infecting humans are highly prevalent infecting ∼2 billion people worldwide, causing inflammatory responses, malnutrition and anemia that are the primary cause of morbidity. In addition, helminth infections of cattle have a significant economic impact on livestock production, milk yield and fertility.
