G-quadruplexes (GQs) are four-stranded nucleic acid secondary structures formed by guanosine (G)-rich DNA and RNA sequences. It is becoming increasingly clear that cellular processes including gene expression and mRNA translation are regulated by GQs. GQ structures have been extensively characterized, however little attention to date has been paid to ...

RNA G-Quadruplexes: G-quadruplexes with “U” Turns
Current Pharmaceutical Design, 2012G-quadruplexes are non canonical secondary structures held together by Hoogsteen bonded planar guanine quartets formed in G-rich sequences in DNA and RNA. Considerable research over the past three decades has contributed to a great deal of understanding of these unusual structures in DNA.

Macrocyclic G-Quadruplex Ligands
Current Medicinal Chemistry, 2010G-quadruplex stabilizing compounds have recently received increased interest due to their potential application as anticancer therapeutics. A significant number of structurally diverse G-quadruplex ligands have been developed. Some of the most potent and selective ligands currently known are macrocyclic structures which have been modeled after the ...

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.

Whilst DNA spends much of its time in the double-stranded form, frequently in storage, wrapped around histones and packaged as chromatin, it can also form other complex structures, which may play a role in natural regulation and gene control. These alternative structures therefore also present an interesting novel series of targets for artificial ...

DNA Repair, 2023
Guanine-rich DNA sequences can fold into stable four-stranded structures called G-quadruplexes or G4s. Research in the past decade demonstrated that G4 structures are widespread in the genome and prevalent in regulatory regions of actively transcribed genes.

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
