Human Telomeric G-Quadruplex Structures and G-Quadruplex-Interactive Compounds [PDF]
G-quadruplexes are noncanonical secondary structures formed in DNA sequences containing consecutive runs of guanines. It has been shown that the 3' G-rich single-stranded overhangs of human telomeres can form G-quadruplex structures, and the human telomeric DNA G-quadruplexes are considered attractive targets for anticancer drugs.

Elevated levels of G-quadruplex formation in human stomach and liver cancer tissues.
Four-stranded G-quadruplex DNA secondary structures have recently been visualized in the nuclei of human cultured cells. Here, we show that BG4, a G-quadruplex-specific antibody, can be used to stain DNA G-quadruplex structures in patient-derived tissues

G-Quadruplexes Involving Both Strands of Genomic DNA Are Highly Abundant and Colocalize with Functional Sites in the Human Genome. [PDF]
The G-quadruplex is a non-canonical DNA structure biologically significant in DNA replication, transcription and telomere stability. To date, only G4s with all guanines originating from the same strand of DNA have been considered in the context of the ...

Role of the central cations in the mechanical unfolding of DNA and RNA G-quadruplexes. [PDF]
Cations are known to mediate diverse interactions in nucleic acids duplexes but they are critical in the arrangement of four-stranded structures. Here, we use all-atom molecular dynamics simulations with explicit solvent to analyse the mechanical ...

NMR Studies of G-Quadruplex Structures and G-Quadruplex-Interactive Compounds [PDF]
G-quadruplexes are noncanonical, four-stranded nucleic acid secondary structures formed in sequences containing consecutive runs of guanines. These G-quadruplex structures have been found to form in nucleic acid regions of biological significance, including human telomeres, gene promoters, and untranslated regions of mRNA.

G-quadruplexes in helminth parasites
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.
