This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of endogenous peptides is important for discovering critical elements involved in many physiological processes and disorders. Neuropeptides are endogenous peptide hormones that regulate these processes by binding to receptors to initiate cellular signaling pathways. Discovery of neuropeptide function is an increasingly popular avenue for disease therapeutics research, resulting in increased need for improved neuropeptide characterization methods. Although mass spectrometry (MS) is well-suited for neuropeptide analysis due to its high sensitivity and capacity for untargeted, global neuropeptide measurements, there are still technical challenges that must be overcome. For example, neuropeptide sequences within a peptide family are highly homologous and therefore must be analyzed in their intact form to obtain high sequence coverage for confident identification and often require high resolution instrumentation. This becomes more challenging as sequence length and post-translational modification complexity increases. In this thesis, I will discuss my efforts in improving MS-based neuropeptidomic workflows, specifically in relation to "top-down" protein and peptide characterization, while highlighting improvements in identification and quantification of peptides through optimized fragmentation and cysteine reactive labeling. I will also discuss my contributions to our group's novel software, HyPep, enabling utility for confident neuropeptide identification. Altogether, these methods have contributed to increased neuropeptide coverage and can be translated to the analysis of other peptide classes.This thesis begins with two reviews of recent developments in MS-based analysis of neuropeptides. Each review outlines examples of how advancements in MS sample preparation, MS acquisition, data analysis, and technology has increased our understanding of neuropeptides, and provides insight on promising directions for further development within each section. My research contributions in Professor Lingjun Li's research group started by applying peptidomics workflows to quantify changes in neuropeptide expression due to hypoxia stress in a crustacean animal model, C. sapidus. Using the same animal model, we also increased the number of detectable neuropeptides using matrix-assisted laser desorption/ionization (MALDI)-MS imaging by incorporating novel tissue wash steps during sample preparation. Over 100 putative peptidomic biomarkers for different levels of hypoxia severity and duration were discovered within multiple tissue types. Four neuropeptide biomarkers were examined for functional activity and two neuropeptides were discovered to increase cardiac output ex vivo, including the first-ever reported function for a crustacean hyperglycemic hormone precursor-related peptide (CPRP). Since CPRP (3.5 kDa) is co-released with crustacean hyperglycemic hormone (CHH) neuropeptide (8.5 kDa), an important neuropeptide that regulates glucose metabolism, we did not detect CHH in these hypoxia studies because its larger size prevented confident detection using typical neuropeptidomic MS workflow and data acquisition methods. Previous members of our research group have developed MS methods to sequence CHH, but limitations of those methods included requiring multiple MS instruments or reliance on targeted MS strategies in which information of potential novel neuropeptides is lost. I built upon those MS acquisition and data analysis methods and was able to sequence novel CHH isoforms and proteoforms, without assistance from genomic or transcriptomic-based sequence prediction, using a Thermo Orbitrap Fusion Lumos instrument. Additionally, I developed novel sample preparation methods to reduce the disulfide bonds and alkylate all six cysteine residues on CHH at high efficiency (83-89% labeling efficiency). While developing methods for CHH are beneficial for analyzing mid-size (8-10 kDa) peptides, I sought to also advance general neuropeptidomics data analysis pipeline. A novel concept for neuropeptide identification software, called HyPep, was created 10 years ago but was not finished and could not be used. To make the software usable, I incorporated features typically used in peptide-spectrum matching (PSM)-based algorithms in proteomics software, such as a false discovery rate. I optimized the software parameters which resulted in HyPep outperforming an analogous commercial software in identifying neuropeptides from four crustacean neuronal tissue types. Collectively, this dissertation is devoted to advancing sample preparation, data acquisition, and data analysis strategies for neuropeptidomics, and these methods are also potentially translatable to analyze other classes of endogenous peptides.

Available in PDF, EPUB and Kindle. Book excerpt: Crustacean preparations have been successfully used for more than 50 years to investigate the principles which enable nerve cells and neural circuitry to perform in a wide variety of functions. The proud record of information of general significance obtained from crayfish and lobster nervous systems testifies that the use of an experimental system precisely matching theoretical and experimental requirements ofa measurement is an essential part of the success. In some respects, the secondarily diversified vertebrate and mammalian nervous systems pose severe obstacles to experimentation and measurement, whereas the crustacean nervous system recommends itself by being composed of individual neurons of unique morphology and physiology, which can be used repeatedly in several preparations. Moreover, a restricted number of invariantly displayed behaviors enable the experimenter to correlate neuron activity with parts of the behavior easier. Experts use these advantages to focus on a well-defined neuron and mechanism and to take a convincing measurement within a minimum amount oftime. In this book distinguished neurobiologists, the leading experts in the field, have joined efforts to present research using crustacean experimental systems. Thus they have contributed comprehensive information regarding a nervous system other than that ofvertebrates and mammalians, that ofcrustaceans. The accumulated knowledge on the crustacean nervous system shows that it is clearly divergent in evolution but functions in a similar way to neuronal circuitry found in the vertebrate system and can be used to interpret it.

Available in PDF, EPUB and Kindle. Book excerpt: About 90 per cent of the 10,000 known species of the Crustacea Decapoda live in oceans and adjacent coastal and estuarine regions, and most of them pass through a complex life history comprising a benthic (juvenile-adult) and a planktonic (larval) phase. The larvae show a wide array of adaptations to the pelagic environment, including modifications in their functional morphology, anatomy, the molting cycle, nutrition, growth, chemical composition, metabolism, energy partitioning, ecology and behaviour.;All these traits are reviewed in this volume, attempting to promote an integrated, multidisciplinary view of the biology of larval Decapoda and other crustacean taxa. Emphasis is placed on the lesser-known anatomical, bioenergetic and ecophysiological aspects of larval life, as morphology has already been extensively documented. Changes in biological parameters (for example, rates of feeding, growth, metabolism) are shown in successive developmental stages, within individual stages, and as responses to environmental factors. Particular attention is paid to interrelationships between intrinsic phenomena (molting cycle, organogenesis, growth) and the overlaying effects of extrinsic factors (for example, food, temperature, salinity, pollution). Concluding from the available data, major bias and gaps in present knowledge of larval biology are identified and discussed as to their potential significance in future research.

Download or read book The Welfare of Invertebrate Animals written by Claudio Carere and published by Springer. This book was released on 2019-07-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the welfare of invertebrates, which make up 99% of animal species on earth. Addressing animal welfare, we do not often think of invertebrates; in fact we seldom consider them to be deserving of welfare evaluation. And yet we should. Welfare is a broad concern for any animal that we house, control or utilize – and we utilize invertebrates a lot. The Authors start with an emphasis on the values of non-vertebrate animals and discuss the need for a book on the present topic. The following chapters focus on specific taxa, tackling questions that are most appropriate to each one. What is pain in crustaceans, and how might we prevent it? How do we ensure that octopuses are not bored? What do bees need to thrive, pollinate our plants and give us honey? Since invertebrates have distinct personalities and some social animals have group personalities, how do we consider this? And, as in the European Union’s application of welfare consideration to cephalopods, how do the practical regulatory issues play out? We have previously relegated invertebrates to the category ‘things’ and did not worry about their treatment. New research suggest that some invertebrates such as cephalopods and crustaceans can have pain and suffering, might also have consciousness and awareness. Also, good welfare is going to mean different things to spiders, bees, corals, etc. This book is taking animal welfare in a very different direction. Academics and students of animal welfare science, those who keep invertebrates for scientific research or in service to the goals of humans, as well as philosophers will find this work thought-provoking, instructive and informative.
Download or read book Chemical Communication in Crustaceans written by Thomas Breithaupt and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crustaceans are ecologically and economically important organisms. They constitute one of the dominant invertebrate groups on earth, particularly within the aquatic realm. Crustaceans include some of the preferred scientific model organism, profitable aquaculture specimen, but also invasive nuisance species threatening native animal communities throughout the world. Chemoreception is the most important sensory modality of crustaceans, acquiring important information about their environment and picking up the chemical signals that mediate communication with conspecifics. Significant advances have been made in our understanding of crustacean chemical communication during the past decade. This includes knowledge about the identity, production, transfer, reception and behavioral function of chemical signals in selected crustacean groups. While it is well known that chemical communication is an integral part of the behavioral ecology of most living organisms, the intricate ways in which organisms allocate chemicals in communication remains enigmatic. How does the environment influence the evolution of chemical communication? What are the environmental cues that induce production or release of chemicals? How do individuals economize production and utilization of chemicals? What is the importance of molecule specificity or mix of a molecule cocktail in chemical communication? What is the role of chemical cues in multimodal communication? How does the ontogenetic stage, the sex or the physiological status of an individual affect its reaction to chemical cues? Many of these questions still represent important challenges to biologists.
Download or read book Sexual Biology and Reproduction in Crustaceans written by Thanumalaya Subramoniam and published by Academic Press. This book was released on 2016-09-27 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual Biology and Reproduction in Crustaceans covers crustacean reproduction as it deals with the structural morphology of the gamete-producing primary sex organs, such as the testis and ovary, the formation and maturation of gametes, their fusion during fertilization, and embryonic development that lead to the release of larvae. Constituting a diverse assemblage of animals, crustaceans are best known by their common representatives, such as shrimps, lobsters, and crabs, but also include many more less familiar, but biologically important forms. This work covers the variety of ways in which both male and female gametes are produced by evolving different sexual systems in crustaceans, the range of reproductive systems, and the accordingly, and highly diverse, mechanistic modes of sex determination. In addition, the book features such topics as genetic and environmental determinants in sex determination pattern, variability of mechanisms of fertilization among different species, the origin of different mating systems, the associated mating and brooding behaviors, and the adaptive ability to different environmental conditions with discussion on the evolutionary ecology of social and sexual systems in certain species, which have shown eusocial tendencies, similar to social insects. Marine species occupying diversified ecological niches in tropical and temperate zones reproduce under definitive environmental conditions. Therefore, reproductive ecology of different crustaceans inhabiting different ecological niches also constitutes another important aspect of the work, along with yolk utilization and embryogenesis leading to release of different larval forms, which reflect on their aquatic adaptability. Forms a valuable source of recent references on the current research in crustacean reproductive physiology Covers various mating and breeding systems, providing illustrative examples for sexual selection, parental care of developing eggs and embryos, and the evolution of other reproductive behaviors Features contributions written in the form of review articles, enabling readers to not only gain information in the respective subject, but also help them stimulate ideas in their chosen field of research Includes a glossary created by the author to define technical terms Demonstrates the ability of crustacean species to serve as useful model systems for other organisms, to investigate issues related to sexual conflict, mate choice, and sperm competition Discusses techniques in endocrine research to help researchers in aquaculture develop protocols in the control of reproduction
