General description
DNA G-quadruplex structures are associated with a number of important aspects of genome function, which include transcription, recombination and replication. Single-stranded guanine (G)-rich DNA can form stable secondary structures called G-quadruplexes (G-tetrads or G4), which can influence methylation at CpG islands (CGIs). G4 structure is reported to be tightly associated with CGI hypomethylation in the human genome. Four guanine bases can associate through Hoogsteen hydrogen bonding to form a square planar structure called a guanine tetrad (G-tetrad), and two or more G-tetrads can stack on top of each other to form a G-quadruplex. The quadruplex structure is further stabilized by the presence of a cation, especially potassium, which sits in a central channel between each pair of tetrads. A DNA G-tetrad can be formed within one DNA strand (intramolecular), between two DNA strands (bimolecular), or four DNA strands (tetramolecular). G4 DNA can arise anywhere in the genome where sufficiently long stretches of single-stranded G-rich DNA are exposed during replication, transcription or recombination. Chemical analysis of quadruplex-forming oligonucleotides has revealed the existence of a plethora of dynamic quadruplex structures with varying stabilities. The diverse nature of G4 DNA structures makes it an attractive topic in molecular biomedical research.(Ref.: Mao, SQ et al., (2018). Nat. Struc. Mol. Biol. 25(10); 951-957).

The most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) is an expanded G4C2 repeat [(G4C2)exp] in C9ORF72. ALS/FTD-associated toxicity has been traced to the RNA transcribed from the repeat expansion [r(G4C2)exp], which sequesters RNA-binding proteins

DNA G-quadruplex is a non-canonical secondary structure that could epigenetically regulate gene expression. To investigate the regulating role of G-quadruplex, we devised an integrating method to perform the algorithm profiling and genome-wide analysis for the dynamic change of genomic G-quadruplex

Three-stranded R-loop structures have been associated with genomic instability phenotypes. What underlies their wide-ranging effects on genome stability remains poorly understood. Here we combined biochemical and atomic force microscopy approaches with single molecule R-loop footprinting to demonstrate that R-loops formed
