Available in PDF, EPUB and Kindle. Book excerpt: A detailed understanding of living systems requires tools to examine and manipulate biological processes. Small molecules and optical imaging technologies are uniquely suited for this purpose. Small molecules enable the specific manipulation of biomolecular targets, and optical imaging permits the real-time observation of molecular and cellular processes in vivo. This dissertation describes a combination of chemical tool development and imaging strategies to address the following biological problems: 1) specific modification of the genome 2) exquisite control of protein function 3) observing cell-cell interactions in living animals. Chapter One describes a technology for targeted gene modification via the induction of double strand breaks in genomic DNA. The chapter begins with an overview of the field of gene targeting, and documents the design, synthesis, and testing of a novel method for high efficiency homologous recombination. The method relies on engineering two reagents, a small molecule DNA targeting element and a nuclease fusion protein. The targeting element, a peptide nucleic acid (PNA), was designed and synthesized to target DNA via Watson-Crick base pairing. The PNA also was covalently linked to the small molecule, trimethoprim, to recruit a DHFR nuclease fusion protein to a specific DNA site. Our studies show that the individual interactions of PNA/DNA and of PNA/nuclease can readily occur. Further, the ternary complex of PNA, DNA, and nuclease can form in solution. Chapters Two, Three, and Four describe the development and further characterization of a general method to perturb protein stability and function. Briefly, an unstable protein domain, termed a destabilizing domain (DD), can confer instability to a fused protein of interest and promote its rapid degradation. This instability can be rescued by the addition of a small molecule, Shield-1. Our work in Chapter Two describes the use of this system to regulate protein function in living mammals. In one example, we show that regulation of a secreted protein, the immunomodulatory cytokine IL-2, can control tumor burden in mouse models. Additionally, we used the DD to control the function of TNF-[Alpha] after systemic delivery to a tumor. Chapter Three expands on these in vivo efforts by employing the system to regulate secreted FGF2, an important modulator of bone formation, for skeletal tissue engineering. Shield-1 induction of FGF2 causes induction of bone formation in a calvarial-defect model. Chapter Four presents our observations on the behavior of the DD in various cellular environments --the cytoplasm, nucleus, endoplasmic reticulum, and mitochondria- and in the presence of small molecules that modulate protein production, degradation, and local protein quality control machinery. These data indicate that the levels of the DD, in the presence and absence ligand, is dependent on its subcellular locale and protein homeostasis machinery. The fifth chapter of this dissertation reports the development of a method to assess spatiotemporal cell-cell relationships in real-time and in living animals. The method is based on small-molecule diffusion of an activatable substrate between two populations of cells, thus allowing assessment of cell-cell proximity in vivo via bioluminescence imaging. One cell population catalyzes the release of a caged luciferin. The free luciferin can diffuse to a nearby population of cells expressing luciferase capable of light-emitting catalysis. Thus the luciferase cells in closest proximity to the "pool" of free luciferin emit the most light. We demonstrate the utility of this system in vitro and in vivo and are currently investigating its use for the detection of cancer and early metastatic disease in mouse models.

Download or read book Data Processing Handbook for Complex Biological Data Sources written by Gauri Misra and published by Academic Press. This book was released on 2019-03-23 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data Processing Handbook for Complex Biological Data provides relevant and to the point content for those who need to understand the different types of biological data and the techniques to process and interpret them. The book includes feedback the editor received from students studying at both undergraduate and graduate levels, and from her peers. In order to succeed in data processing for biological data sources, it is necessary to master the type of data and general methods and tools for modern data processing. For instance, many labs follow the path of interdisciplinary studies and get their data validated by several methods. Researchers at those labs may not perform all the techniques themselves, but either in collaboration or through outsourcing, they make use of a range of them, because, in the absence of cross validation using different techniques, the chances for acceptance of an article for publication in high profile journals is weakened. - Explains how to interpret enormous amounts of data generated using several experimental approaches in simple terms, thus relating biology and physics at the atomic level - Presents sample data files and explains the usage of equations and web servers cited in research articles to extract useful information from their own biological data - Discusses, in detail, raw data files, data processing strategies, and the web based sources relevant for data processing

Download or read book Green Toxicology written by Alexandra Maertens and published by Royal Society of Chemistry. This book was released on 2022-02-01 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Green toxicology is an integral part of green chemistry. One of the key goals of green chemistry is to design less toxic chemicals. Therefore, an understanding of toxicology and hazard assessment is important for any chemist working in green chemistry, but toxicology is rarely part of most chemists' education. As a consequence, chemists lack the toxicological lens necessary to view chemicals in order to design safer substitutions. This book seeks to fill that gap and demonstrate how a basic understanding of toxicology, as well as the tools of in silico and in vitro toxicology, can be an integral part of green chemistry. R&D chemists, product stewards, and toxicologists who work in the field of sustainability, can all benefit from integrating green toxicology principles into their work. Topics include in silico tools for hazard assessment, toxicity testing, and lifecycle considerations, this book aims to act as a bridge between green toxicologists and green chemists.
Download or read book High Pressure Chemistry Biochemistry and Materials Science written by R. Winter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph, which is the outcome of the ASI on High Pressure Chemistry, Biochemistry, and Materials Science, illustrates new developments in the field of high pressure science. In fact, for chemists, biochemists, and materials scientists, pressure as an experimental variable represents a tool which provides unique information about systems of materials studied. It is interesting to note how the growth of the high pressure field is also reflected in the content of the recent ASI's dealing with this field. The ASI High Pressure Chemistry held in 1977 was followed by the ASI High Pressure Chemistry and Biochemistry held in 1986, and the coverage of the present ASI also includes applications to materials science. In view of the teaching character of the ASI, it is natural that main contributions to this volume present overviews of the different subfields or applications of high pressure research. In contrast, contributed papers offer more specialized aspects of various high pressure studies. The various contributions to this volume make clear the impressive range of fundamental and applied problems that can be studied by high pressure techniques, and also point towards a major growth of high pressure science and technology in the near future. This ASI focused mainly on advances achieved in the six years since the previous ASI devoted to the high pressure field. The organization of this volume is as follows.
Download or read book Biological Magnetic Resonance written by Lawrence Berliner and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological magnetic resonance (NMR and EPR) is a rapidly expanding area of research with much activity in most universities and research institutions. International conferences are held biennially with an increasing number of participants. With the introduction of sophisticated and continuously im proving instrumentation, biological magnetic resonance is approaching the state of a common physical method in biochemical, biomedical, and bio logical research. The lack of monograpbs on the subject had been con spicuous for a long time. This gap started to close only recently. However, because of the rapid expansion and intensive research, many texts are dated by the time of their appearance. Therefore we have undertaken the editing of a series that is intended to provide the practicing chemist, biochemist, or biologist with the advances and progress in selected contemporary topics. In seeking to make the series as authoritative as possible, we have invited authors who have not only made significant contributions but who are also currently active in their fields. We hope that their expertise as well as their first hand experience as reflected in the chapters of this volume will be of benefit to the reader, inter alia, in planning his own experiments and in critically evaluating the current literature.
