Although embryonic stem cells currently enjoy the public limelight and show great pr- ise for cell based medical therapies, it is the adult stem cells which are responsible for the body's natural ability to fght disease, heal and recover, or fail and succumb to various maladies. The study of mammalian adult stem cells has surged recently, most likely from a maturation of stem cell studies in the classical developmental model organisms and in hematopoeisis. All the tissues of the body examined so far are generated and regenerated from stem cells, it has been an important frst step to adapt or devise new methods to identify and obtain these cells in quantity and purity for further study. Culture techniques have been optimized for managing the growth and differentiation of stem cells in vitro; as some stem cells are pluripotent, often the method is to guide the fate of such cells among the possible differentiation fates. Much of this work, and that in the classical model org- isms, has helped defne the aspects of the stem cell environment or niche that are crucial for both growth and differentiation, and these studies have moved in vivo at increasingly higher resolution. Importantly, the in vivo niche is a current target for bioengineering the matrix and signaling factors. Herein, we present methods for studying six types of mammalian stem cells, m- mary, neural, mesenchymal, endothelial, dendritic, and muscle.
Oxidation is any reaction in which electrons are removed from a molecule, thus increasing the number of binding sites on the molecule that are able to react with other atoms and molecules.;This volume addresses oxidant-reduction or redox and antioxidant sensitive molecular mechanisms and how they are implicated in different disease processes. Recent work in this area has revealed that these mechanisms may be linked with different disease processes, such as immune response, cell proliferation, inflammation, metabolism, ageing and cell death. Possible strategies to pharmacologically and/or nutritionally manipulate such redox-sensitive molecular responses are emphasized.
Antisense technology is the ability to manipulate gene expression
within mammalian cells providing powerful experimental approaches
for the study of gene function and gene regulation. For example,
methods that inhibit gene expression permit studies which probe the
normal function of a specific product within a cell. Such
methodology can be used in many disciplines such as pharmacology,
oncology, genetics, cell biology, developmental biology, molecular
biology, biochemistry, and neurosciences. This volume will be a
truly important tool in biomedical-oriented research.
From New York Times bestselling author Sam Kean comes more
incredible stories of science, history, language, and music, as
told by our own DNA.
When I received an invitation from Ron Landes (Landes Bioscience) to edit a book on CtBP family proteins, I was gratified to realize that the importance of these proteins has reached the level of deserving a 'separate' book. As the reader can see, there has been significant advancement in our understanding of the fijnctions of these proteins in the past ten years since CtBPl was cloned in our laboratory. Genetic and biochemical studies with Drosophila provided the critical evidence to show that dCtBP is a transcriptional CO repressor. Genetic studies with mutant mice have established that these proteins are essential for animal development. The CtBP family proteins are unique in several aspects. They were the first among proteins containing a metabolic enzyme fold to be implicated in transcriptional regulation. The vertebrate CtBPs exhibit distinct nuclear and cytosolic activities. The crystal struaures of CtBPl and molecular modeling studies have illuminated the mo- lecular basis of its dual activity and the interaction with target peptides. The organization of the vertebrate CtBP2 gene has provided a novel example of genomic consolidation indicating how a single gene could code for two di- verse proteins. I believe that this book will be a valuable reference source for new researchers to understand more about the CtBP family proteins and their role in growth, development and oncogenesis.
In this book leading researchers in the field discuss the state-of-the-art of many aspects of SAPK signaling in various systems from yeast to mammals.

This revised edition provides up-to-date protocols developed in the HSC field. A team of leading researchers supply this volume with in-depth, readily reproducible methods for effective characterization of HSC and their developmental potential. The book provides detailed flow cytometry protocols for thorough analysis of enriched HSC populations, and offers a variety of transplantation approaches to measure HSC function in vivo. This is a much needed technical resource in the critically important field of stem cell investigation.
Computer access is the only way to retrieve up-to-date sequences
and this book shows researchers puzzled by the maze of URLs, sites,
and searches how to use internet technology to find and analyze
genetic data. The book describes the different types of databases,
how to use a specific database to find a sequence that you need,
and how to analyze the data to compare it with your own work.
Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.
This book provides an overview of the Ocimum genus from its genetic diversity to genome sequences, metabolites and their therapeutic utilities. Tulasi, Ocimum tenuiflorum, as a member of the family Lamiaceae, is a sacred plant in India. The plants of this genus Ocimum are collectively referred to as Basil and holy basil is worshipped in the Hindu religion. Basils are reservoirs of diverse terpenoids, phenylpropanoids and flavonoids, in addition to commercially important aromatic essential oils. In 2016, two working groups in India published the genome sequence in two different genotypes of Ocimum tenuiflorum. To help the readers understand the complexities of the genus and different chemotypes, this book accumulates all the available information on this medicinal plant including the genome. The complete knowledge may enable researchers to generate specific chemotypes in basil either through conventional breeding or development of transgenic lines. It also makes it possible to investigate the medicinal nature of holy basil compared to different species of the same genus.

The laws of inheritance were considered quite superficial until
1903, when the chromosome theory of heredity was established by
Sutton and Boveri. The discovery of the double helix and the
genetic code led to our understanding of gene structure and
function. For the past quarter of a century, remarkable progress
has been made in the characterization of the human genome in order
to search for coherent views of genes. The unit of inheritance
termed factor or gene, once upon a time thought to be a trivial an
imaginary entity, is now perceived clearly as the precise unit of
inheritance that has continually deluged us with amazement by its
complex identity and behaviour, sometimes bypassing the university
of Mendel's law.
Biochemistry And Genetics of RecQ-Helicases provides a background into the role of helicases in general and RecQ helicases specifically in DNA repair. Helicases- enzymes which break down hydrogen bonds between nucleic acid strands in a nucleoside triphosphate-dependent manner-are ubiquitous in biology, participating in processes as diverse as replication, repair, recombination, transcription, and translation. The RecQ-family helicases are a group of helicases which have important roles in the maintenance of genomic stability in many organisms. In humans, mutations in three RecQ-family helicases lead to disease. This book thoroughly examines these helicases. Mutations in the BLM gene lead to Bloom syndrome, a disorder characterized by a susceptibility to many types of cancer. Mutations in the WRN gene cause Werner syndrome, a disease which in some respects resembles premature aging. Finally, mutations in a newly characterized RecQ-family member, RECQ4, may lead to the very rare recessive disorder Rothmund-Thomson syndrome, a condition characterized by developmental abnormalities and some aging-like manifestations. This book is intended for any researchers invested in these particular disorders, or with a general interest in DNA.
Bringing together nanoscience with stem cell and bacterial cell biology, this thesis is truly interdisciplinary in scope. It shows that the creation of superparamagnetic nanoparticles inside a protein coat, followed by chemical functionalisation of the protein surface, provides a novel methodology for cell magnetisation using incubation times as short as one minute. Crucially, stem cell proliferation and multi-lineage differentiation capacity is not impaired after labelling. Due to the unspecific labelling mechanism, this thesis also shows that the same magnetic protein nanoparticles can be used for rapid bacterial magnetisation. Thus, it is possible to magnetically capture and concentrate pathogens from clinical samples quickly and highly efficiently.
Volume 2 has focused on aspects of the pituitary gland both
anterior (growth hormone and prolactin receptors, and GH action)
and posterior (vasopressin) pituitary. In addition, thyroid cancer
and steroidogenic enzymes and precocious puberty are covered.
Finally, the "hot topics" include leptin and growth factor
signaling.
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.
As studies using microarray technology have evolved, so have the data analysis methods used to analyze these experiments. The CAMDA (Critical Assessment of Microarray Data Analysis) conference was the first to establish a forum for a cross section of researchers to look at a common data set and apply innovative analytical techniques to microarray data. Methods of Microarray Analysis V includes selected papers from CAMDA'04, and focuses on data sets relating to a significant global health issue, malaria. Previous books focused on classification (V. I), pattern recognition (V. II), quality control issues (V. III), and associating array data with a survival endpoint, lung cancer, (V. IV). The contributions come from research fields including statistics, biology, computer science and mathematics. Part of the book is devoted to review papers, which provide a more general look at various analytical approaches. It also presents some background readings for the advanced topics discussed in the CAMDA papers.
The packaging of genomic DNA together with core histones, linker histones, and other functional proteins into chromatin play key roles in nuclear processes such as transcription, replication, repair and recombination. Research in the last two decades has unveiled the fact that many diseases involve an aberration of these processes at the chromatin level. Similarly, it is becoming clear that different processes such as chromatin assembly, remodeling of chromatin structure coupled to covalent modification of histone and non-histone proteins, chromatin modifying enzymes and last but not the least, important DNA-templated phenomena are the potential drug targets for diseases such as different types of cancer, neurodegenerrative diseases, AIDS etc.

reference for students and professionals involved in medicinal
chemistry, pharmacology, (eco)toxicology, and agrochemistry. Each
comprehensive chapter is written by a distinguished researcher in
the field.
Human pluripotent stem cells such as human embryonic stem cells (hESC) and induced pluripotent stem cells (iPSC) with their unique developmental plasticity hold immense potential as cellular models for drug discovery and in regenerative medicine as a source for cell replacement. While hESC are derived from a developing embryo, iPSC are generated with forced expression of key transcription factors to convert adult somatic cells to ESC-like cells, a process termed reprogramming. Using iPSC overcomes ethical issues concerning the use of developing embryos and it can be generated from patient-specific or disease-specific cells for downstream applications. Pluripotent Stem Cells: Methods and Protocols highlights the best methods and systems for the entire work flow. Divided into four convenient sections, topics include a focus on producing iPSC from diverse somatic sources, media systems for expanding ESC and iPSC with detailed protocols for directed differentiation into specific lineages, commonly used cellular and molecular characterization methods , and the potential application of labeled stem cells with specific methods for cloning, gene delivery and cell engineering. Written in the successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Pluripotent Stem Cells: Methods and Protocols seeks to serve both professionals and novices with its well-honed methodologies in an effort to further our knowledge of this essential cellular feature. |
