Book Description
The ability of DNA to exist in configurations other than its classical double-stranded form has been known for many years. There has been a spectacular recent surge of interest in these forms, notably in the three-stranded or triple-helical form. Triplex-like nucleic acids are now known to exist in vivo, and may well participate in significant biological processes. Interest in triple-helical nucleic acids has been greatly stimulated by their potential exploitation to control gene expression, serve as tools in genome mapping strategies, etc. The authors have written an encyclopedic introduction to nucleic acid triplexes based on many years of familiarity with the topic. The book includes information on chemistry, conformation, physical properties, applications, and hypotheses about the biological role of triplexes. It pays particular attention to the different methods for investigating these molecules, a feature which will be welcomed by those new to the field.

Triple Helix Forming Oligonucleotides
Author: Claude Malvy
Publisher: Springer Science & Business Media
ISBN: 1461551773
Category : Science
Languages : en
Pages : 296
Book Description
Sequence-specific DNA binding ligands, amongst which triple helix forming oligonucleotides are the most efficient as yet, represent promising tools in a number of fields. One of their most promising applications is as antiviral tools: they can specifically target a viral gene, even if it is integrated into the host genome, and be used to specifically inactivate the viral gene or even destroy the cells harboring this gene. However, from science fiction to science there remains a gap; and we are at the moment on the threshold of this fascinating field. Triple Helix Forming Oligonucleotides considers the different aspects of the design and improvement, current or future, of these molecules and their structural analysis, as well as their applications, with special emphasis on the attempts to obtain biological effects of these potentially important tools. What emerges is that the current state of the research is encouraging, and that these molecules are already useful in some biotechnology applications.

The Alkali Metal Ions: Their Role for Life
Author: Astrid Sigel
Publisher: Springer
ISBN: 3319217569
Category : Science
Languages : en
Pages : 663
Book Description
MILS-16 provides an up-to-date review of the impact of alkali metal ions on life. Their bioinorganic chemistry and analytical determination, the solid state structures of bio-ligand complexes and the properties of alkali metal ions in solution in the context of all kinds of biologically relevant ligands are covered, this includes proteins (enzymes) and nucleic acids (G-quadruplexes). Minerals containing sodium (Na+) and potassium (K+) are abundant in the Earth's crust, making Na+ and K+ easily available. In contrast, the alkali elements lithium (Li+), rubidium, and cesium are rare and the radioactive francium occurs only in traces. Since the intra- and extracellular, as well as the compartmental concentrations of Na+ and K+ differ significantly, homeostasis and active transport of these ions are important; this involves transporters/carriers and pore-forming ion channel proteins. Systems like Na+/K+-ATPases, H+/K+-ATPases or Na+/H+ antiporters are thoroughly discussed. The role of K+ in photosynthesis and the role of Na+ in charging the "battery of life" are pointed out. Also, the relationships between alkali metal ions and diseases (e.g., Parkinson or traumatic brain injury) are covered and the relevance of Li+ salts in medicine (pharmacology and mechanism) is reviewed. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 16, The Alkali Metal Ions: Their Role for Life, which are written by 44 internationally recognized experts from 12 nations. The impact of this vibrant research area is manifested in nearly 3000 references, over 30 tables and more than 150 illustrations (two thirds in color). MILS-16 also provides excellent information for teaching. Astrid Sigel, Helmut Sigel, and Roland K. O. Sigel have long-standing interests in Biological Inorganic Chemistry. Their research focuses on metal ion interactions with nucleotides and nucleic acids and on related topics. They edited previously 44 volumes in the series Metal Ions in Biological Systems.

Small Molecule DNA and RNA Binders
Author: Martine Demeunynck
Publisher: John Wiley & Sons
ISBN: 3527605665
Category : Science
Languages : en
Pages : 754
Book Description
The development of molecules that selectively bind to nucleic acids has provided many details about DNA and RNA recognition. The range of such substances, such as metal complexes, peptides, oligonucleotides and a wide array of synthetic organic compounds, is as manifold as the functions of nucleic acids. Nucleic acid recognition sequences are often found in the major or minor groove of a double strand, while other typical interactions include intercalation between base pairs or the formation of triple or quadruple helices. One example of a binding mode that has recently been proposed is end stacking on such complex structures as the telomere tetraplex. In this comprehensive book, internationally recognized experts describe in detail the important aspects of nucleic acid binding, and in so doing present impressive approaches to drug design. Since typical substances may be created naturally or synthetically, emphasis is placed on natural products, chemical synthesis, the use of combinatorial libraries, and structural characterization. The whole is rounded off by contributions on molecular modeling, as well as investigations into the way in which any given drug interacts with its nucleic acid recognition site.

Small-molecule Transcription Factor Inhibitors in Oncology
Author: Khondaker Miraz Rahman
Publisher: Royal Society of Chemistry
ISBN: 1788015274
Category : Medical
Languages : en
Pages : 214
Book Description
Oncogenic transcription factors are an increasingly important target for anticancer therapies. Inhibiting these transcription factors could allow tumour cells to be "reprogrammed", leading to apoptosis or differentiation from the malignant phenotype. As the use of kinase inhibitors is gradually declining, transcription factor inhibition is the next hot topic for oncology research and merits much attention. This book highlights recent progress in the development of small-molecule inhibitors of oncogenic transcription factors. It also presents the evidence that this important protein class can be modulated in a number of ways to develop novel classes of therapeutic agents. The broad range of aspects covered by the book is noteworthy and renders it enormously valuable. This title serves as a unique reference book for postgraduates, academic researchers and practitioners working in the fields of biochemistry, biotechnology, cell and molecular biology and bio-inorganic chemistry.

Nucleic Acid-Metal Ion Interactions
Author: Nicholas V Hud
Publisher: Royal Society of Chemistry
ISBN: 1847558763
Category : Science
Languages : en
Pages : 448
Book Description
Natural biochemical processes are routinely being discovered in living cells that involve RNA. Some of these processes, such as RNA interference, are now being exploited for biotechnology and medicinal applications. DNA has also proven in recent years to be more than a passive storehouse of information. For example, non-B-form DNA structures formed by G-rich DNA have been shown to participate in the regulation of gene expression, a discovery that presents new possibilities for drug targets in the genome. The current quest to understand how nucleic acid functions at the most fundamental level requires that we have a detailed understanding of nucleic acid-metal ion interactions. Because RNA and DNA are polyanions the structure and biological function of these biopolymers depends strongly on their association with metal ions. While this intimate connection between metal ions and nucleic function has been appreciated for decades, the noncovalent and dynamic nature of these interactions has continually presented challenges to the development of accurate and quantitative descriptions. Over the past few years the development of solution state spectroscopic techniques and the achievement of high resolution X-ray crystal structures have provided tremendous insights into the nature of nucleic acid-metal ion interactions, including direct evidence for their importance in determining nucleic acid structure, from the dictation of folding pathways followed by large RNA molecules to the subtle modulation of DNA groove widths. This new book provides a comprehensive review of the experimental studies that define our current understanding of nucleic acid-metal ion interactions with a particular emphasis being placed on experimental biophysical studies. However, the book is not merely a current review of the literature, as original material and fresh perspectives on published results are also presented. Particularly noteworthy topics include: -The chapter by Williams and fellow workers which reviews information provided by x-ray crystal structures and discusses what this information has revealed about the unique nature of Mg2+ interactions with RNA phosphate groups. The authors provide fresh insights, based upon structural comparisons, for how these interactions govern the local folding pathways of RNA. By dedicating separate chapters to the participation of metal ions in the kinetics and thermodynamics of RNA folding, this volume provides a more in depth treatise of both areas than is typically possible for reviews in which these two related, but distinct, topics are combined -Polyelectrolyte models of nucleic acids have proven to be extremely valuable for understanding the sequestering counterions in a so-called diffuse cloud around polymeric DNA. J. Michael Schurr provides a comprehensive review of polyanion models. Despite the success of polyelectrolyte models in describing some physical properties of nucleic acids, this topic is not always sufficiently understood by many researchers to make use of these models and this chapter serves as a valuable and up to date introduction to this topic. -The chapter by Pizarro and Sadler on metal ion-nucleic acid interactions in disease and medicine is complemented by a chapter by Lippert on coordinative bond formation between metal ions and nucleic acid bases. Together, these two chapters provide an overview of transition metal ion interactions with nucleic acids that illustrates the promise and peril that is associated with direct metal ion coordination to nucleic acid bases in living cells. The book is sufficiently detailed to serve as a reference source for researchers active in the field of nucleic acids biophysics and molecular biology. In addition, chapter authors have added introductory material and enough background material in each chapter so that the book can also can serve as an entry point for students and researchers that have not previously worked in the field which will make the book of lasting value and more accessible by a wider audience.
