Full Description
Recent work has revealed that stabilizing G-quadruplexes in telomeric DNA inhibits telomerase activity, providing impetus for the development of G-quartet-interacting drugs, while G-quartet-containing oligonucleotides have been recognized as a potent class of aptamers effective against STAT3 and other transcription factors implicated in oncogenesis, proving these guanine-quartets to be a vital and rich area for future study. In "G-Quadruplex DNA: Methods and Protocols", experts in the field present a collection of detailed techniques for studying G-quartet formation, dynamics, and molecular recognition. Written in the highly successful Methods in Molecular Biology™ series format, chapters include brief introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls.
Authoritative and cutting-edge, "G-Quadruplex DNA: Methods and Protocols "promises to be a useful resource for those familiar with G-quartets as well as an easy entry point for those researchers from diverse fields who are just developing an interest in the exciting implications of G-quadruplex DNA.
