New Findings Revolutionize Concepts of Gene Function

Endogenous small RNAs have been found in various organisms, including humans, mice, flies, worms, fungi, and bacteria. Furthermore, it 's been shown that microRNAs acting as cellular rheostats have the ability to modulate gene expression. In higher eukaryotes, microRNAs may regulate as much as 50 percent of gene expression.

Regulation of Gene Expression by Small RNAs brings together the pioneering work of researchers who discuss their work involving a wide variety of small RNA regulatory pathways in organisms ranging from bacteria to humans. In addition to exploring the biogenesis and processing of these regulatory RNAs, they also consider the functional importance of these pathways in host organisms. Assisting current and future researchers, this unique groundbreaking work

The massive research effort known as the Human Genome Project is an attempt to record the sequence of the three trillion nucleotides that make up the human genome and to identify individual genes within this sequence. The description and classification of sequences is heavily dependent on mathematical and statistical models. This short textbook presents a brief description of several ways in which mathematics and statistics are being used in genome analysis and sequencing.

Information is central to the evolution of biological complexity, a physical system relying on a continuous supply of energy. Biology provides superb examples of the consequent Darwinian selection of mechanisms for efficient energy utilisation. Genetic information, underpinned by the Watson-Crick base-pairing rules is largely encoded by DNA, a molecule uniquely adapted to its roles in information storage and utilisation.This volume addresses two fundamental questions. Firstly, what properties of the molecule have enabled it to become the predominant genetic material in the biological world today and secondly, to what extent have the informational properties of the molecule contributed to the expansion of biological diversity and the stability of ecosystems. The author argues that bringing these two seemingly unrelated topics together enables Schroedinger's What is Life?, published before the structure of DNA was known, to be revisited and his ideas examined in the context of our current biological understanding.

This book constitutes the refereed proceedings of the 4th RECOMB Comparative Genomics Satellite Workshop, RECOMB-CG 2006. The 17 revised full papers presented were carefully reviewed and selected from 34 initial submissions. The papers address a broad variety of aspects and components of the field of comparative genomics, ranging from new quantitative discoveries about genome structure and process to theorems on the complexity of computational problems inspired by genome comparison.

The complexity of genome evolution poses many exciting challenges to devel- ers of mathematical models and algorithms, who have recourse to a spectrum of algorithmic, statisticalandmathematicaltechniques, rangingfromexact, heur- tic, ?xed-parameter and approximation algorithms for problems based on par- mony models to Monte Carlo Markov Chain algorithms for Bayesian analysis of problems based on probabilistic models. The annual RECOMB Satellite Workshop on Comparative Genomics (RECOMB ComparativeGenomics)is aforumonallaspects andcomponents of this ?eld, rangingfromnew quantitativediscoveriesabout genomestructureand process to theorems on the complexity of computational problems inspired by genome comparison.

In its short but active history, the use of DNA typing has revolutionized criminal investigations. It is almost inconceivable to bring a case to trial without positive identification through what is now our most accurate means. Proficiency with the methodology, principles, and interpretation of DNA evidence is crucial for today's criminalist. An introductory text, Forensic DNA Analysis: A Laboratory Manual presents a contextual history and overview of the science and use of DNA typing. Logically organized, with clear, concise language, this manual provides a fundamental understanding of forensic DNA analysis and a thorough background in the molecular techniques used to determine an individual's identity. Students are provided with a sound working knowledge of the investigative methodology, scientific principles, and the analysis and interpretation of the resulting data. After laying a foundation on the rules of the laboratory, the basic scientific principles, and the types of biological materials, such as hair, blood, and bone, this practical, hands-on manual provides 12 exercises outlining techniques commonly used in DNA typing. Designed to be performed in a common laboratory, the experiments cover DNA extraction, concentration, and assessment; DNA analysis using restriction fragment length polymorphisms; polymerase chain reaction and PCR-based typing tests; short tandem repeat analysis; and mitochondrial DNA analysis. Many of the procedures described have been adapted from methods used in federal, state, and private forensic laboratories and are suitable to a wide range of applications. There is also an extensive glossary for DNA typing terminology and basic terms used in molecular biology. Instilling confidence, analytical clarity, and a sense of curiosity, this comprehensive introduction is the perfect tool for grasping the techniques and applications of forensic DNA analysis and exploring the questions and issues involved in forensic science investigations.

This book is about the increasing significance of DNA profiling for crime investigation in modern society. It focuses on developments in the UK as the world-leader in the development and application of forensic DNA technology and in the construction of DNA databases as an essential element in the successful use of DNA for forensic purposes. The book uses data collected during the course of Wellcome Trust funded research into police uses of the UK National DNA Database (NDNAD) to describe the relationship between scientific knowledge and police investigations. It will be illustrated throughout by reference to some of the major UK criminal cases in which DNA evidence has been presented and contested. Chapters in the book explain the scientific developments which have enabled DNA profiling to be applied to criminal investigation, the ways in which the state has directed this and how genetic technology has risen to such preeminence; how DNA evidence moved from its use in individual prosecutions to a major role in intelligence led policing, and saw the development of the UK National DNA Database; how legislative support for the NDNAD was mobilized, enabling the police to obtain and use genetic information on individuals. Finally, the authors examine the ways in which the DNA Expansion Programme, built on the supposed potential for the NDNAD to contribute to criminal detection, has been incorporated into a broader crime reduction strategy, and explore the implications for policing, governance and security of the continued expansion of the range and scope of the NDNAD.

Research in the ?eld of gene regulation is evolving rapidly in an ever-changing s- enti?c environment. Microarray techniques and comparative genomics have enabled more comprehensive studies of regulatory genomics and are proving to be powerful tools of discovery. The application of chromatin immunoprecipitation and microarrays (chIP-on-chip) to directly study the genomic binding locations of transcription factors has enabled more comprehensive modeling of regulatory networks. In addition, c- plete genome sequences and the comparison of numerous related species has dem- strated that conservation in non-coding DNA sequences often provides evidence for cis-regulatory binding sites. That said, much is still to be learned about the regulatory networks of these sequenced genomes. Systematic methods to decipher the regulatory mechanism are also crucial for c- roboratingthese regulatorynetworks.Thecoreof thesemethodsarethe motifdiscovery algorithms that can help predict cis-regulatory elements. These DNA-motif discovery programsarebecomingmoresophisticatedandare beginningto leverageevidencefrom comparative genomics (phylogenetic footprinting) and chIP-on-chip studies. How to use these new sources of evidence is an active area of research.

For over half a century, we have been in the thrall of the double-helicaln structure of DNA, which, in an instant, revealed that information can be transferred between generations by a simple rule, A pairs with T, G pairs with C. In its beautiful simplicity, this structure, along with the table of codons worked out in the following decade, had entranced us into believing that we can fully understand the information content of a DNA sequence, simply by treating it as text that is read in a linear fashion. While we have learned much based on this assumption, there is much we have missed. Far from a passive tape running through a reader, genomes contain information that appears in new forms which create regions with distinct behavior. Some are "gene rich," some mobile, some full of repeats and duplications, some sticking together across long evolutionary distances, some readily breaking apart in tumor cells. Even protein-coding regions can carry additional information, taking advantage of the flexible coding options provided by the degeneracy of the genetic code. The chapters in this volume touch on one or more of three interconnected themes; information can be implied, rather than explicit, in a genome; information can lead to focused and/or regulated changes in nucleotide sequences; information that affects the probability of distinct classes of mutation has implications for evolutionary theory.

Flow cytometry is a sensitive and quantitative platform for the measurement of particle fluorescence. In flow cytometry, the particles in a sample flow in single file through a focused laser beam at rates of hundreds to thousands of particles per second. During the time each particle is in the laser beam, on the order of ten microseconds, one or more fluorescent dyes associated with that particle are excited. The fluorescence emitted from each particle is collected through a microscope objective, spectrally filtered, and detected with photomultiplier tubes.
Flow cytometry is uniquely capable of the precise and quantitative molecular analysis of genomic sequence information, interactions between purified biomolecules and cellular function. Combined with automated sample handling for increased sample throughput, these features make flow cytometry a versatile platform with applications at many stages of drug discovery. Traditionally, the particles studied are cells, especially blood cells; flow cytometry is used extensively in immunology.
This volume shows how flow cytometry is integrated into modern biotechnology, dealing with issues of throughput, content, sensitivity, and high throughput informatics with applications in genomics, proteomics and protein-protein interactions, drug discovery, vaccine development, plant and reproductive biology, pharmacology and toxicology, cell-cell interactions and protein engineering.

DNA as the genetic material is a topic of intense interest in the 21st century with the familiar and iconic Watson-Crick double helix having a vital importance for its function. However, there are further complexities beyond the double helix, including supercoiling, knotting and catenation, that are less widely appreciated and understood but which are critical to its function. This book explains these topological aspects of DNA structure in a clear and approachable style that will be appreciated by both students and researchers interested in DNA structure and function.

This is the story of how three men won the Nobel Prize for their research on the humble nematode worm "C. elegans"; how their extraordinary discovery led to the sequencing of the human genome; how a global multibillion-dollar industry was born; and how the mysteries of life were revealed in a tiny, brainless worm.

In 1998 the nematode worm -- perhaps the most intensively studied animal on earth -- was the first multicellular organism ever to have its genome sequenced and its DNA mapped and read. "When we understand the worm, we will understand life," predicted John Sulston, one of the three Nobel laureates, and his prediction proved astonishingly accurate. Four years later, the research that led to this extraordinary event garnered three scientists a Nobel Prize. Along with Robert Horvitz and Sydney Brenner, Sulston discovered the phenomenon of programmed cell death in the worm, an essential concept that explains how biological development occurs in animal life and, as Horvitz later showed, how it occurs in human life. "C. elegans" is about as simple as an animal can be, but understanding its genetic organization is helping to reveal the mechanisms of life and, by extension, the mechanisms of our own lives. "In the Beginning Was the Worm" shows that in order to unlock the secrets of the human genome we must first understand the worm.

But this story is about more than just the worm. It is about how an eccentric group of impassioned scientists toiled in near anonymity for years, driven only by a deep passion for knowledge and scientific discovery. It is the story of countless hours of research, immense ambition, and one of the greatest discoveries in human history.

Crick and Watson's discovery of the structure of DNA fifty years ago marked one of the great turning points in the history of science. Biology, immunology, medicine and genetics have all been radically transformed in the succeeding half-century, and the double helix has become an icon of our times. This fascinating exploration of a scientific phenomenon provides a lucid and engaging account of the background and context for the discovery, its significance and afterlife, while a series of essays by leading scientists, historians and commentators offers uniquely individual perspectives on DNA and its impact on modern science and society.

This volume describes high-throughput approaches to a series of robust, established methodologies in molecular genetic studies of population samples. Such developments have been essential not only to linkage and association studies of single-gene and complex traits in humans, animals and plants, but also to the characterisation of clone banks, for example in mapping of genomes. Chapters have been written by developers or highly experienced end-users concerned with a diverse array of biological applications. The book should appeal to any researcher for whom costs and throughput in their genetics laboratory have become an issue.
