MicroRNAs from basic science to disease biology Posted by R Santhosh Kalash on 10/20/2013 12:09:00 pm No comments

MicroRNAs (miRNAs) are RNA molecules, conserved by evolution, that regulate gene expressions and their recent discovery is revolutionising both basic biomedical research and drug discovery. Expression levels of MiRNAs have been found to vary between tissues and with developmental stages and hence evaluation of the global expression of miRNAs potentially provides opportunities to identify regulatory points for many different biological processes. This wide-ranging reference work, written by leading experts from both academia and industry, will be an invaluable resource for all those wishing to use miRNA techniques in their own research, from graduate students, post-docs and researchers in academia to those working in R&D in biotechnology and pharmaceutical companies who need to understand this emerging technology. From the discovery of miRNAs and their functions to their detection and role in disease biology, this volume uniquely integrates the basic science with industry application towards drug validation, diagnostic and therapeutic development.

Cell and Molecular Biology: Concepts and Experiments, Sixth Edition Posted by R Santhosh Kalash on 8/25/2013 03:19:00 pm No comments

A molecular model of the membrane of a synaptic vesicle. Within nerve cells, a synaptic vesicle consists of a cellular membrane surrounding a soluble compartment filled with neurotransmitter molecules. Vesicles of this type are assembled in the vicinity of a nerve cell’s nucleus and then transported to the tip of the axon. There the vesicle awaits the arrival of a nerve impulse that will induce it to fuse with the overlying plasma membrane, releasing its contents into the narrow cleft that separates the nerve cell from a neighboring cell. The three dimensional model of this membrane was constructed using known structures of the various proteins along with information on their relative numbers obtained from the analysis of purified synaptic vesicles. The image on the front cover shows a synaptic vesicle that has been cut in half; the lipid bilayer that forms the core of the vesicle membrane is shown in green. The image on the back cover shows the surface structure of an intact vesicle. Most of the proteins present in this membrane are required for the interaction of the vesicle with the plasma membrane. The large blue protein at the lower right of the vesicle contains a ring of subunits that rotates within the lipid bilayer as the protein pumps hydrogen ions into the vesicle. The elevated concentration of hydrogen ions within the vesicle is subsequently used as an energy source for the uptake of neurotransmitter molecules from the surrounding cytosol. These images provide the most comprehensive model of any cellular membrane yet to be studied and they reveal how much this membrane is dominated by protein—both within the bilayer itself and on both membrane surfaces.

Principles and Techniques of Biochemistry and Molecular Biology, Seventh Edition Posted by R Santhosh Kalash on 8/22/2013 10:01:00 pm No comments

In designing the content of this latest edition we continued our previous policy of placing emphasis on the recommendations we have received from colleagues and academics outside our university. Above all, we have attempted to respond to the invaluable feedback from student users of our book both in the UK and abroad. In this seventh edition we have retained all 16 chapters from the previous edition. All have been appropriately updated to reflect recent developments in their fields, as exemplified by the inclusion of a section on stem cells in the cell culture chapter. Three of these chapters have new authors and have been completely rewritten. Robert Burns, Scottish Agricultural Science Agency, Edinburgh has written the chapter on immunochemical techniques, and Andreas Hofmann, Eskitis Institute of Molecular Therapies, Griffith University, Brisbane, Australia has written the two chapters on spectroscopic techniques. We are delighted to welcome both authors to our team of contributors.

In addition to these changes of authors, two new chapters have been added to the book. Our decision taken for the sixth edition to include a section on the biochemical principles underlying clinical biochemistry has been well received and so we have extended our coverage of the subject and have devoted a whole chapter (16) to this subject. Written in collaboration with Dr John Fyffe, Consultant Biochemist, Royal Hospital for Sick Children, Yorkhill, Glasgow, new topics that are discussed in the chapter include the diagnosis and management of kidney disease, diabetes, endocrine disorders including thyroid dysfunction, conditions of the hypothalamus–pituitary– adrenal axis such as pregnancy, and pathologies of plasma proteins such as myeloma.

Case studies are included to illustrate how the principles discussed apply to the diagnosis and treatment of individual patients with the conditions. Our second major innovation for this new edition is the introduction of a new chapter on drug discovery and development. The strategic approaches to the discovery of new drugs has been revolutionised by developments in molecular biology. Pharmaceutical companies now rely on many of the principles and experimental techniques discussed in the chapters throughout the book to identify potential drug targets, screen chemical libraries and to evaluate the safety and efficacy of selected candidate drugs. The new chapter illustrates the principles of target selection by reference to current drugs used in the treatment of atherosclerosis and HIV/AIDS, emphasises the strategic decisions to be taken during the various stages of drug discovery and development and discusses the issues involved in clinical trials and the registration of new drugs.

We continue to welcome constructive comments from all students who use our book as part of their studies and academics who adopt the book to complement their teaching. Finally, we wish to express our gratitude to the authors and publishers who have granted us permission to reproduce their copyright figures and our thanks to Katrina Halliday and her colleagues at Cambridge University Press who have been so supportive in the production of this new edition.

Molecular Biology of Gene, Fifth Edition Posted by R Santhosh Kalash on 8/22/2013 12:33:00 am 1 comment

The long-awaited new edition of James D. Watson's classic text, Molecular Biology of the Gene, has been thoroughly revised and is published to coincide with the 50th anniversary of Watson and Crick's paper on the structure of the DNA double-helix. Twenty-one concise chapters, co-authored by five highly respected molecular biologists, provide current, authoritative coverage of a fast-changing discipline, giving both historical and basic chemical context. Divided into four parts: Genetics and Chemistry, Central Dogma, Regulation, and Methods. For college instructors, students, and anyone interested in molecular biology and genetics. 

James D. Watson was Director of Cold Spring Harbor Laboratory from 1968 to 1993 and is now its President. He spent his undergraduate years at the University of Chicago and received his Ph.D. in 1950 from Indiana University. Between 1950 and 1953, he did postdoctoral research in Copenhagen and Cambridge, England. While at Cambridge, he began the collaboration that resulted in the elucidation of the double-helical structure of DNA in 1953. (For this discovery, Watson, Francis Crick, and Maurice Wilkins were awarded the Nobel Prize in 1962.) Later in1953, he went to the California Institute of Technology. He moved to Harvard in 1955, where he taught and did research on RNA synthesis and protein synthesis until 1976. He was the first Director of the National Center for Genome Research of the National Institutes of Health from 1989 to 1992. Dr. Watson was sole author of the first, second, and third editions of Molecular Biology of the Gene, and a co-author of the fourth edition. These were published in 1965, 1970, 1976, and 1987 respectively. Watson has also been involved in two other textbooks: he was one of the original authors of Molecular Biology of the Cell and is also an author of Recombinant DNA: a short course.Tania A. Baker is the Whitehead Professor of Biology at the Massachusetts Institute of Technology and an Investigator of the Howard Hughes Medical Institute. She received a B.S. in biochemistry from the University of Wisconsin, Madison, and a Ph.D. in biochemistry from Stanford University in 1988. Her graduate research was carried out in the laboratory of Professor Arthur Kornberg and focused on mechanisms of initiation of DNA replication. She did postdoctoral research in the laboratory of Dr. Kiyoshi Mizuuchi at the National Institutes of Health, studying the mechanism and regulation of DNA transposition. Her current research explores mechanisms and regulation of genetic recombination, enzyme-catalyzed protein unfolding, and ATP-dependent protein degradation. Professor Baker received the 2001 Eli Lilly Research Award from the American Society of Microbiology and the 2000 MIT School of Science Teaching Prize for Undergraduate Education. She is co-author (with Arthur Kornberg) of the book DNA Replication, Second Edition.Stephen P. Bell is a Professor of Biology at the Massachusetts Institute of Technology and an Assistant Investigator of the Howard Hughes Medical Institute. He received B.A. degrees from the Department of Biochemistry, Molecular Biology, and Cell Biology and the Integrated Sciences Program at Northwestern University and a Ph.D. in biochemistry at the University of California, Berkeley in 1991. His graduate research was carried out in the laboratory of Robert Tjian and focused on eukaryotic transcription.

Molecular Biotechnology: Principles and Applications of Recombinant DNA Technology Posted by R Santhosh Kalash on 8/19/2013 12:01:00 am No comments

Molecular biotechnology emerged as a new research field that arose as a result of the fusion in the late 1970s of recombinant DNA technology and traditional industrial microbiology. Whether one goes to the movies to see Jurassic Park with its ingenious but scientifically untenable plot of cloning dinosaurs, reads in the newspaper about the commercialization of a new “biotech” tomato that has an extended shelf life, or hears one of the critics of molecular biotechnology talking about the possibility of dire consequences from genetic engineering, there is a significant public awareness about recombinant DNA technology. In this book, we introduce and explain what molecular biotechnology actually is as a scientific discipline, how the research in the area is conducted, and

how this technology may realistically impact on our lives in the future. We have written Molecular Biotechnology: Principles and Applications of Recombinant DNA to serve as a text for courses in biotechnology, recombinant

DNA technology, and genetic engineering or for any course introducing both the principles and the applications of contemporary molecular biology methods. The book is based on the biotechnology course we have offered for the past 12 years to advanced undergraduate and graduate students from the biological and engineering sciences at the University of Waterloo. We have written this text for students who have an understanding of basic ideas from biochemistry, molecular genetics, and microbiology. We are aware that it is unlikely that students will have had all of these courses before taking a course on biotechnology. Thus, we have tried to develop the topics in this text by explaining their broader biological context before delving into molecular details. This text emphasizes how recombinant DNA technology can be used to create various useful products. We have, wherever possible, used experimental results and actual methodological strategies to illustrate basic concepts,

and we have tried to capture the flavor and feel of how molecular biotechnology operates as a scientific venture. The examples that we have selected—from a vast and rapidly growing literature—were chosen as case studies that not only illustrate particular points but also provide the reader with a solid basis for understanding current research in specialized areas of molecular biotechnology. Nevertheless, we expect that some of our examples will be out of date by the time the book is published, because molecular

biotechnology is such a rapidly changing discipline.

For the ease of the day-to-day practitioners, scientific disciplines often develop specialized terms and nomenclature. We have tried to minimize the use of technical jargon and, in many instances, have deliberately used a simple phrase to describe a phenomenon or process that might otherwise have been expressed more succinctly with technical jargon. In any field of study, synonymous terms that describe the same phenomenon exist. In molecular biotechnology, for example, recombinant DNA technology, gene cloning, and genetic engineering, in a broad sense, have the same meaning. When an important term or concept appears for the first time in this text, it is followed in parentheses with a synonym or equivalent expression. An extensive glossary can be found at the end of the book to help the reader with the terminology of molecular biotechnology.

Lewin's Gene VIII Posted by R Santhosh Kalash on 4/13/2013 10:14:00 pm No comments

For courses in Molecular Biology, Molecular Genetics, and Gene Regulation. Two decades ago Benjamin Lewin's Genes revolutionized the teaching of molecular biology and molecular genetics by introducing a unified approach to bacteria and higher organisms. Genes has remained at the cutting edge of molecular biology, covering gene structure, organization, and expression. Originally the text opened with the genetic code and worked toward genome structure. Genes VIII changed the approach to begin with the sequence of the human and other genomes and starts with complete coverage of recent advances in genomics. The coverage of genomics is then integrated throughout the text. In striving to maintain currency, the new edition has updated coverage on genome organization, DNA replication, gene regulation and many other new topics. Book Description Genes VIII changed the approach to begin with the sequence of the human and other genomes and starts with complete coverage of recent advances in genomics. The coverage of genomics is then integrated throughout the text.
