Human Papillomavirus G-Quadruplexes
Biochemistry, 2013Infection with human papillomaviruses (HPVs) is one of the most common sexually transmitted infections and can lead to development of head and neck, skin, and anogenital cancer, including cervical cancer, which represents one of the world's most significant health problems.

AbstractG‐quadruplexes are noncanonical structures formed by G‐rich DNA and RNA sequences that fold into a four‐stranded conformation. Experimental studies and computational predictions show that RNA G‐quadruplexes are present in transcripts associated with telomeres, in noncoding sequences of primary transcripts and within mature transcripts.

Thermodynamics of G-quadruplexes
2012In 1910 Ivar Bang reported that concentrated solutions of guanylic acid formed a gel. It took half a century before Gellert et al. in 1962 discovered the structural motif, a guanine-quartet, to be the basis for guanylic acid gelation. This chapter starts with a historical overview and gives credit to Ivar Bang and several other pioneers in the field ...

NMR spectroscopy of G-quadruplexes
Methods, 2012G-rich DNA and RNA sequences can form four-stranded structures called G-quadruplexes. Such structures have gained significant interest in the past decade with increasing evidence of their biological role. G-quadruplex structures can be polymorphic and dynamic. NMR spectroscopy has played an important role in G-quadruplex research. Here we review on the

Transposable elements and G-quadruplexes
Chromosome Research, 2015A significant part of eukaryotic genomes is formed by transposable elements (TEs) containing not only genes but also regulatory sequences. Some of the regulatory sequences located within TEs can form secondary structures like hairpins or three-stranded (triplex DNA) and four-stranded (quadruplex DNA) conformations.

Nonaqueous G-Quadruplex Ionogels
LangmuirSupramolecular ionogels, as an emerging class of materials, utilize the intriguing properties of ionic liquids (ILs) and offer a promising method for constructing functional materials in anhydrous solvents. G-Quadruplex, assembled from guanine-rich nucleic acid building blocks, is an important structure closely associated with life and leads to the ...

G-quadruplexes as therapeutic targets
Biopolymers, 2000The ends of chromosomes (telomeres) consist of tandem repeats of guanine-rich sequences. In eukaryotics, telomeric DNA is single stranded for the final few hundred bases. These single-stranded sequences can fold into a variety of four-stranded structures (quadruplexes) held together by quartets of hydrogen-bonded guanine bases.

Modulation of histone modifications and G-quadruplex structures by G-quadruplex-binding proteins
Biochemical and Biophysical Research Communications, 2020The functions of local conformations of non-B form DNA and RNA, such as the G-quadruplex, are thought to be regulated by their specific binding proteins. They regulate the formation of G-quadruplexes in cells and affect the biological functions of G-quadruplexes.

Metal ions stabilize quadruplex nucleic acids by coordinating the O6 guanine atoms from G-quartets. These quartets form the basic motif of quadruplex structures. This article systematically surveys the available crystallographic data on native quadruplexes, their ligand complexes and (in one instance) a protein complex.
