Conformational profiling of a G-rich sequence within the c-KIT promoter [PDF]
G-quadruplexes (G4) within oncogene promoters are considered to be promising anticancer targets. However, often they undergo complex structural rearrangements that preclude a precise description of the optimal target.

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.

Multimerization rules for G-quadruplexes [PDF]
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.

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 ...

Mapping and characterization of G-quadruplexes in Mycobacterium tuberculosis gene promoter regions [PDF]
Mycobacterium tuberculosis is the causative agent of tuberculosis (TB), one of the top 10 causes of death worldwide in 2015. The recent emergence of strains resistant to all current drugs urges the development of compounds with new mechanisms of action ...

New findings on the d(TGGGAG) sequence: Surprising anti-HIV-1 activity [PDF]
The biological relevance of tetramolecular G-quadruplexes especially as anti-HIV agents has been extensively reported in the literature over the last years. In the light of our recent results regarding the slow G-quadruplex folding kinetics of ODNs based

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
