Available in PDF, EPUB and Kindle. Book excerpt: The exciting Fibroblast Growth Factor (FGF) field lies at the crossroads of cell signaling, development, evolution, trafficking, physiology and human disease. A current challenge is to understand the mechanisms used by this signaling pathway to accomplish its myriad tasks in patterning the embryo, forming organs, and maintaining systems in the adult animal. My thesis work has focused on tackling this challenge in the model system of Drosophila melanogastor, the vinegar fly. By examining functional domains of Thisbe and Pyramus, FGF ligands in the fly, we have begun to understand the properties of Drosophila FGFs and the way in which they may contribute to regulation of FGF signaling. FGF ligands in vertebrates are small molecules that bind to a corresponding receptor through two immunoglobulin domains. The FGF ligands in Drosophila are predicted to be much larger molecules than their vertebrate homologs. Whether Drosophila FGFs bind to the receptor as full-length proteins or are first cleaved to smaller molecules was previously unknown. My thesis work addressed this question through experiments in Drosophila embryos and Drosophila cell culture. I found evidence that the N-terminal FGF-domain alone is capable of signaling by itself in the embryo. In addition, experiments in cell culture showed that Thisbe and Pyramus are secreted as small forms, presumably as a result of intracellular proteolytic cleavage. Cleaved forms for Thisbe and Pyramus were detected in embryonic extracts as well. The Ths ligand is also present outside the cell as a full-length form and this form may act to regulate the diffusion or activity of the ligand. Addition of the Thisbe C-terminus to the Pyramus N-terminus to make a Pyramus-Thisbe chimeric protein creates a protein that has reduced activity compared to Thisbe alone. The opposite Thisbe-Pyramus chimera creates a protein that has increased activity compared to Ths alone. Over the course of animal evolution the FGF superfamily has diversified in many ways. Understanding the mechanism of FGF signaling in Drosophila and comparing this to other Drosophilids, insects, and more distantly related animals will reveal the likely makeup of the ancestral FGF signaling system.

Download or read book Scientific Frontiers in Developmental Toxicology and Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 2000-12-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

Download or read book Receptor Tyrosine Kinases Structure Functions and Role in Human Disease written by Deric L. Wheeler and published by Springer. This book was released on 2014-11-26 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Receptor Tyrosine Kinase: Structure, Functions and Role in Human Disease, for the first time, systematically covers the shared structural and functional features of the RTK family. Receptor Tyrosine Kinases (RTKs) play critical roles in embryogenesis, normal physiology and several diseases. And over the last decade they have become the Number 1 targets of cancer drugs. To be able to conduct fundamental research or to attempt to develop pharmacological agents able to enhance or intercept them, it is essential first to understand the evolutionary origin of the 58 RTKs and their roles in invertebrates and in humans, as well as downstream signaling pathways. The assembly of chapters is written by experts and underscores commonalities between and among the RTKs. It is an ideal companion volume to The Receptor Tyrosine Kinase: Families and Subfamilies, which proceeds, family by family through all of the specific subfamilies of RTKs, along with their unique landmarks.
Download or read book Midkine From Embryogenesis to Pathogenesis and Therapy written by Mine Ergüven and published by Springer Science & Business Media. This book was released on 2012-06-12 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carl Edward Sagan’s (1934-1996) one of the famous quotation was “Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.“ From past to date, well-known molecules, enzymes, proteins, lipids and carbohydrates are studied in the pathogenesis of several diseases both as a diagnostic/prognostic biomarker and therapeutic agent. The underlying mechanism of unexplained diseases and failure of therapies are frequently studied with well-known biomarkers, but remain unclear in many cases. As Dr. Sagan said other keys are still waiting to be known in some forgotten corner of a body universe, we find strength to propose that one of them can be the growth factor with cytokine activity named “Midkine” This book summarizes the extensive up-to-date literature overeview with the lastest work of experts about midkine in a detailed format that conveys its role as both a pathologic factor and therapeutic agent.
Download or read book Molecular Embryology written by Paul T. Sharpe and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people have some interest in embryos; this probably results, in part, from their interest in understanding the biological origins of themselves and their offspring and, increasingly, concerns about how environmental change such as pollution might affect human development. Obviously, et- cal considerations preclude experimental studies of human embryos and, c- sequently, the developmental biologist has turned to other species to examine this process. Fortunately, the most significant conclusion to be drawn from the experimental embryology of the last two decades is the manner in which orthologous or closely related molecules are deployed to mediate similar - velopmental processes in both vertebrates and invertebrates. The molecular mechanisms regulating processes fundamental to most animals, such as axial patterning or axon guidance, are frequently conserved during evolution. (It is now widely believed that the differences between phyla and classes are the result of new genes, arising mostly by duplication and divergence of extant sequences, regulating the appearance of derived characters. ) Other vertebrates are obviously most likely to use the same devel- mental mechanisms as humans and, within the vertebrate subphylum, the - parent degree of conservation of developmental mechanism is considerable. It has long been recognized that particular vertebrate species offer either d- tinct advantages in investigating particular stages of development or are - pecially amenable to particular manipulations. No single animal can provide all the answers because not all types of experiments can be carried out on a single species.
Download or read book A Handbook of Transcription Factors written by Timothy R. Hughes and published by Springer Science & Business Media. This book was released on 2011-05-10 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transcription factors are the molecules that the cell uses to interpret the genome: they possess sequence-specific DNA-binding activity, and either directly or indirectly influence the transcription of genes. In aggregate, transcription factors control gene expression and genome organization, and play a pivotal role in many aspects of physiology and evolution. This book provides a reference for major aspects of transcription factor function, encompassing a general catalogue of known transcription factor classes, origins and evolution of specific transcription factor types, methods for studying transcription factor binding sites in vitro, in vivo, and in silico, and mechanisms of interaction with chromatin and RNA polymerase.
Download or read book Myofibrillogenesis written by Dipak K. Dube and published by Springer Science & Business Media. This book was released on 2001-10-19 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myofibrillogenesis has been studied extensively over the last 100 years. Until recently, we have not had a comprehensive understanding of this fundamental process. The emergence of new technologies in molecular and cellular biology, combined with classical embryology, have started to unravel some of the complexities of myofibril assembly in striated muscles. In striated muscles, the contractile proteins are arranged in a highly ordered three dimensional lattice known as the sarcomere. The assembly of a myofibril involves the precise ordering of several proteins into a linear array of sarcomeres. Multiple isoforms in many of these proteins further complicate the process, making it difficult to define the precise role of each component. This volume has been compiled as a comprehensive reference on myofibrillogenesis. In addition, the book includes reviews on myofibrillar disarray under various pathological conditions, such as familial hypertrophic cardiomyopathy (FHC), and incorporates a section on the conduction system in the heart. Much of the information in this volume has not been described elsewhere. Presented in a manner to be of value to students and teachers alike, "Myofibrillogenesis" will be an invaluable reference source for all in the fields of muscle biology and heart development.
