G-quadruplex forming sequences are prevalent in eukaryotic cells, especially in telomeres, 5` untranslated strands, and translocation hot spots. G-quadruplexes can inhibit normal cell function, and in healthy cells, are easily and readily unwound by helicase. However, in cancer cells that have mutated helicase these complexes cannot be unwound and leads to potential damage of the cell. This causes replication of damaged and cancerous cells. For therapeutic advances, stabiliz… WebAug 9, 2007 · A G quartet is formed from four guanine residues arranged in a planar configuration, which is stabilized by Hoogsteen-type hydrogen bonds. Several such planar structures can stack and are stabilized by potassium or sodium cations, but they do not form in the presence of lithium cations ( 20–22 ).
