This book relates how, between 1954 and 1961, the biologist Seymour
Benzer mapped the fine structure of the rII region of the genome of
the bacterial virus known as phage T4. Benzer's accomplishments are
widely recognized as a tipping point in mid-twentieth-century
molecular biology when the nature of the gene was recast in
molecular terms. More often than any other individual, he is
considered to have led geneticists from the classical gene into the
molecular age.
Drawing on Benzer's remarkably complete record of his experiments,
his correspondence, and published sources, this book reconstructs
how the former physicist initiated his work in phage biology and
achieved his landmark investigation. The account of Benzer's
creativity as a researcher is a fascinating story that also reveals
intriguing aspects common to the scientific enterprise.
This book highlights the role of the Translationally Controlled
Tumor Protein (TCTP) in cell signaling, cell fate and the resulting
connection to disease development. It begins by discussing the
structure/function of TCTP, before exploring its role in different
species ranging from plants to Drosophila and covering fields such
as development, the cytoskeleton, cell division, DNA fragility and
apoptosis. In turn, the book's final section is devoted to the role
of TCTP in disease, namely asthma and diverse cancers, and
ultimately as a target for the treatment of malignancies. What is
the common denominator between all these processes and why is TCTP
necessary in order for them to occur, even in the worst case such
as cancer? The book seeks to provide meaningful answers to this and
other key questions. Presenting a broad and revealing view on the
topic, it offers an informative guide for scientists and students
alike.
Integration and Visualization of Gene Selection and Gene Regulatory
Networks for Cancer Genome helps readers identify and select the
specific genes causing oncogenes. The book also addresses the
validation of the selected genes using various classification
techniques and performance metrics, making it a valuable source for
cancer researchers, bioinformaticians, and researchers from diverse
fields interested in applying systems biology approaches to their
studies.
This is the first detailed assessment of the development and
implementation of social policy to deal with the problem of the
`mentally deficient' in Britain between 1870 and 1959. Mathew
Thomson analyses all the factors involved in the policy-making
process, beginning with the politics of the legislature and showing
how the demands of central government were interpreted by local
authorities, resulting in a wide and varied distribution of
medical, institutional, and community care in different parts of
the country. The efforts of health professionals, voluntary
organizations and the families themselves are considered, alongside
questions about the influence of changing concepts of class,
gender, and citizenship. The author queries the belief that the
policy of segregation was largely unsuccessful, and reveals a
hitherto unrecognized system of care in the community. He reframes
our understanding of the campaign for sterilization and examines
why British policy-makers avoided extremist measures such as the
compulsory sterilization introduced in Germany and parts of the US
during this period. Thomson shows that the problem of mental
deficiency cannot be understood simply in terms of eugenics but
must also be considered as part of the process of adjusting to
democracy in the twentieth century.
Molecular-Genetic and Statistical Techniques for Behavioral and
Neural Research presents the most exciting molecular and
recombinant DNA techniques used in the analysis of brain function
and behavior, a critical piece of the puzzle for clinicians,
scientists, course instructors and advanced undergraduate and
graduate students. Chapters examine neuroinformatics, genetic and
neurobehavioral databases and data mining, also providing an
analysis of natural genetic variation and principles and
applications of forward (mutagenesis) and reverse genetics (gene
targeting). In addition, the book discusses gene expression and its
role in brain function and behavior, along with ethical issues in
the use of animals in genetics testing. Written and edited by
leading international experts, this book provides a clear
presentation of the frontiers of basic research as well as
translationally relevant techniques that are used by
neurobehavioral geneticists.

a range of useful topics such as determining genome size by flow
cytometry; High Molecular Weight DNA extraction; improvements to a
genome assembly provided by long-range sequencing approaches;
assessments of orthology and single-copy genes at different
phylogenetic levels; detecting regulatory regions with FAIRE,
RAMPAGE, and computational analysis of cis-regulatory modules in
insects; bioinformatics analysis of epigenetic modifications,
high-throughput scanning of insect genomes (TEEseq) for the
presence of endosymbionts, and leveraging genome sequence
information to design RNAi strategies. Written in the highly
successful Methods in Molecular Biology series format, chapters
include introductions to their respective topics, lists of the
necessary materials and reagents, step-by-step, readily
reproducible laboratory protocols, and tips on troubleshooting and
avoiding known pitfalls. Cutting-edge and thorough, Insect
Genomics: Methods and Protocols is a valuable resource for graduate
students, postdocs, and novice research scientists who are
interested in learning more about this developing field.

This astute volume brings together the latest expert research on
adamantinomatous craniopharyngiomas (ACPs). ACPs are histologically
benign but clinically aggressive tumors exhibiting a high
propensity for local invasion into the hypothalamus, optic and
vascular structures. These tumors, as well as the current
treatments, may result in pan-hypopituitarism, diabetes insipidus,
morbid obesity followed by type II diabetes mellitus, blindness, as
well as serious behavioral and psychosocial impairments. Exploring
in detail advances in both the understanding of tumor biology as
well as clinical advances in patient management are explored in
detail, this book will also look towards potential new treatment
approaches. Basic Research and Clinical Aspects of Adamantinomatous
Craniopharyngioma is the first book compiling all current research
on ACPs. Mouse and human studies have unequivocally demonstrated
that mutations in CTNNB1 encoding -catenin underlie the etiology of
the majority, if not all ACP tumors. Genetic studies in mice have
shown that ACPs are tumors of the pituitary gland and not of the
hypothalamus as previously thought, and are derived from Rathke's
pouch precursors. In addition, a role for tissue-specific adult
pituitary stem cells has been revealed as causative of ACP.
Together, these studies have provided novel insights into the
molecular and cellular etiology as well as the pathogenesis of
human ACP. Finally, this volume covers new treatment approaches
that have been shown to be effective both in reducing ACP burden as
well as reducing the morbidity associated with therapy.
Before Mendel, who came closest to the truth about heredity? This book examines the activities of sheep breeders able to transform the appearance and qualities of their stock by combining different traits of body or wool into new patterns. Exploiting what were then untried procedures - individual trait selection, very close inbreeding and progeny testing - they demonstrated inheritance from both sexes and showed how it could be stabilised. Major advances in breeding are associated with the English farmer Robert Bakewell (1725-1795). By the following century, when the same procedures had been established at breeding centres in central Europe, theory as well as practice became the subject of wider attention. In the Brno Sheep Breeders' Society, discussions of patterns of heredity finally gave way to the physiological question, 'What is inherited and how?' The question was posed by Cyrill Napp, abbot of the monastery to which Mendel was admitted six years later.
This volume brings together a set of reviews that provide a summary
of our current knowledge of the proteolytic machinery and of the
pathways of protein breakdown of prokaryotic and eukaryotic cells.
Intracellular protein degradation is much more than just a
mechanism for the removal of incorrectly folded or damaged
proteins. Since many short-lived proteins have important regulatory
functions, proteolysis makes a significant contribution to many
cellular processes including cell cycle regulation and
transciptional control. In addition, limited proteolytic cleavage
can provide a rapid and efficient mechanism of enzyme activation or
inactivation in eukaryotic cells.
In the first chapter, Maurizi provides an introduction to
intracellular protein degradation, describes the structure and
functions of bacterial ATP-dependent proteases, and explores the
relationship between chaperone functions and protein degradation.
Many of the principles also apply to eukaryotic cells, although the
proteases involved are often not the same. Interestingly,
homologues of one of the bacterial proteases, Ion protease, have
been found in mitochondria in yeast and mammals, and homologues of
proteasomes, which are found in all eukaryotic cells (see below),
have been discovered in some eubacteria.
Studies of proteolysis in yeast have contributed greatly to the
elucidation of both lysosomal (vacuolar) and nonlysosomal
proteolytic pathways in eukaryotic cells. Thumm and Wolf (chapter
2) describe studies that have elucidated the functions of
proteasomes in nonlysosomal proteolysis and the contributions of
lysosomal proteases to intracellular protein breakdown. Proteins
can be selected for degradation by a variety of differen
mechanisms. The ubiquitin system is one complex and highly
regulated mechanism by which eukaryotic proteins are targetted for
degradation by proteosomes. In chapter 3, Wilkinson reviews the
components and functions of the ubiquitin system and considers some
of the known substrates for this pathway which include cell cycle
and transcriptional regulators.
The structure and functions of proteosomes and their regulatory
components are described in the two subsequent chapters by Tanaka
and Tanahashi and by Dubiel and Rechsteiner. Proteasomes were the
first known example of threonine proteases. They are multisubunit
complexes that, in addition to being responsible for the turnover
of most short-lived nuclear and cytoplasmic protein, are also
involved in antigen processing for presentation by the MHC class I
pathway. Recent studies reviewed by McCracken and colleagues
(chapter 6) lead to the exciting conclusion that some ER-associated
proteins are degraded by cytosolic proteasomes.
Lysosomes are responsible for the degradation of long-lived
proteins and for the enhanced protein degradation observed under
starvation conditions. In chapter 7 Knecht and colleagues review
the lysosomal proteases and describe studies of the roles of
lysosomes and the mechanisms for protein uptake into lysosomes.
Methods of measuring the relative contribution of different
proteolytic systems (e.g., ubiquitin-proteasome pathway,
calcium-dependent proteases, lysosomes) to muscle protein
degradation, and the conclusions from such studies, are reviewed by
Attai and Taillinder in the following chapter.
Finally, proteases play an important role in signaling apoptosis by
catalyzing the limited cleavage of enzymes. Mason and Beyette
review the role of the major players, caspases, which are both
activated by and catalyze limite proteolysis, and also consider the
involvement of other protoelytic enzymes in this pathway leading
cell death.

Clinical Applications series will be invaluable to scientists,
researchers, advanced students and clinicians working in stem
cells, regenerative medicine or tissue engineering.
This fully updated second edition explores protocols that address
the most challenging aspects of experimental work in ancient DNA,
such as preparing ancient samples for DNA extraction, the DNA
extraction itself, and transforming extracted ancient DNA molecules
for sequencing library preparation. The volume also examines the
analysis of high-throughput sequencing data recovered from ancient
specimens, which, because of the degraded nature of ancient DNA and
common co-extraction of contaminant DNA, has challenges that are
unique compared to data recovered from modern specimens.Written in
the highly successful Methods in Molecular Biology series format,
chapters include introductions to their respective topics, lists of
the necessary materials and reagents, step-by-step, readily
reproducible laboratory protocols, and tips on troubleshooting and
avoiding known pitfalls. Authoritative and cutting-edge, Ancient
DNA: Methods and Protocols, Second Edition aims to serve both
experts and beginners by presenting protocols in a manner that
makes them easily accessible for everyday use in the lab.
Bioremediation refers to the clean-up of pollution in soil,
groundwater, surface water, and air using typically microbiological
processes. It uses naturally occurring bacteria and fungi or plants
to degrade, transform or detoxify hazardous substances to human
health or the environment. For bioremediation to be effective,
microorganisms must enzymatically attack the pollutants and convert
them to harmless products. As bioremediation can be effective only
where environmental conditions permit microbial growth and action,
its application often involves the management of ecological factors
to allow microbial growth and degradation to continue at a faster
rate. Like other technologies, bioremediation has its limitations.
Some contaminants, such as chlorinated organic or high aromatic
hydrocarbons, are resistant to microbial attack. They are degraded
either gradually or not at all, hence, it is not easy to envisage
the rates of clean-up for bioremediation implementation.
Bioremediation represents a field of great expansion due to the
important development of new technologies. Among them, several
decades on metagenomics expansion has led to the detection of
autochthonous microbiota that plays a key role during
transformation. Transcriptomic guides us to know the expression of
key genes and proteomics allow the characterization of proteins
that conduct specific reactions. In this book we show specific
technologies applied in bioremediation of main interest for
research in the field, with special attention on fungi, which have
been poorly studied microorganisms. Finally, new approaches in the
field, such as CRISPR-CAS9, are also discussed. Lastly, it
introduces management strategies, such as bioremediation
application for managing affected environment and bioremediation
approaches. Examples of successful bioremediation applications are
illustrated in radionuclide entrapment and retardation, soil
stabilization and remediation of polycyclic aromatic hydrocarbons,
phenols, plastics or fluorinated compounds. Other emerging
bioremediation methods include electro bioremediation,
microbe-availed phytoremediation, genetic recombinant technologies
in enhancing plants in accumulation of inorganic metals, and
metalloids as well as degradation of organic pollutants,
protein-metabolic engineering to increase bioremediation
efficiency, including nanotechnology applications are also
discussed.
