Investigating DNA G-quadruplex structure function through genome and epigenome engineering
The importance of DNA secondary structures, such as four-stranded DNA G-quadruplexes (G4s), in genome function remains a largely unanswered question. G4s are implicated in transcriptional regulation; however, earlier studies are mostly correlative and do not directly address the role of an …

Interactions Between Platinum-Intercalator Hybrid-Agents and The Human Telomeric G-Quadruplex
… that can fold into a non-duplex secondary DNA structure known as G-quadruplex. Because this form of DNA cannot be processed by telomerase, small molecules that induce and/or stabilize the G-quadruplex structure have potential applications in cancer chemotherapy.

The Role of G-Quadruplex RNA Motif in Fragile X Syndrome
… box domain to bind mRNA targets that form a G-quadruplex structure, structure believed to be important for FMRP recognition of at least a subclass of its mRNA targets. We have hypothesized that the interaction of FMRP with selected relevant mRNA targets occurs in a G-quadruplex dependent …

Structural dynamics of telomeric overhang accessibility
… repeat sequence that can self-fold into a G-quadruplex structure, allowing regulation of the telomere overhang. In addition, telomeric-binding proteins such as POT1 and TPP1 can sequester the overhang to regulate telomerase activity in vivo. Furthermore, existing small molecules that bind …

Identification and Development of Novel Compounds for the Treatment of Human Cancers
… that interact with two key cancer targets, the G-quadruplex of the c-Myc promoter and p-glycoprotein, have been investigated. By developing such compounds, improvements in treatment efficacy is anticipated with an aspiration for decreased mortality attributable to cancer.Formation of DNA secondary …

Molecule recognition of nucleic acids, nucleosides, nucleotides, and their derivatives
… work reported in chapter 4 is focused on the G-quadruplex structure formed in the guanine rich telomeric sequence. Many studies have shown G4 ligands can induce and stabilize G-quadruplex within telomere region and inhibit the activity of telomerase that is overexpressed in 80-90% of cancer …

Crystallographic studies of interactions between ligands and DNA oligonucleotides
… One are two out of only five crystallographic quadruplex/ligand structures reported to date. In both structures daunomycin molecules stack onto a terminal G quartet preventing the G4 quadruplex from destacking and unwinding. The number of interacting ligand molecules depends on the quadruplex …
