Modulating G-quadruplexes for therapeutic intervention: Structural diversity, stability, and emerging nucleic-acid-based strategies.
G-quadruplexes (G4s) are non-canonical nucleic acid structures formed by guanine-rich DNA or RNA sequences. The G4s are formed by planar G-tetrads and stabilized by monovalent metal cations such as potassium or sodium. The structural diversity of G4s arises from differences in strand orientation, loop arrangement, and ...
