Available in PDF, EPUB and Kindle. Book excerpt: This study was undertaken to identify genes involved in axon guidance in the nervous system of Caenorabditis elegans. Due to its unique physiological properties, the nematode worm C. elegans is a powerful genetic model system to study a variety of biological processes. The nervous system of C. elegans is a simple organ comprising 302 neurons. These neurons create stereotypic neuronal networks formed by their anterior-posterior and dorsal-ventral running axons. Here, we took advantage of the recently discovered phenomenon of RNA interference in the worm to identify axon guidance genes. However, the nervous system of C. elegans is refractory to the systemic RNA interference, and delivery of dsRNA molecules to the neighboring non-neuronal cells does not initiate RNAi in the neurons of the worm. Therefore, we started with the identification of mutants of C. elegans that are efficient for RNAi in the nervous system. A standard chemical mutagenesis screen was performed to identify mutants of the worm that showed enhanced RNAi efficiency in the nervous system. One of the mutants (nre-1, for neuronal RNAi efficient) showed marked suppression of gene expression in the nervous system by feeding RNAi approach. We used the nre-1 supersensitive strain as a tool in a reverse genetic screen to identify genes required for axon guidance in C. elegans. A transgenic strain was constructed in the nre-1 background, wherein a subset of interneurons and motor neurons were labeled with the yellow fluorescent protein to visualize axons of the neurons. We used this strain to screen 2416 gene of the worm located on chromosome I by feeding a library of bacterial clones expressing dsRNA fragments specific to the genes. This screen has identified 57 candidate genes that give rise to penetrant axon guidance defects in the commissural and ventral nerve cord axons in C. elegans. The genes identified include genes involved in various cellular processes such as DNA metabolism, translation, transcript.

Download or read book Neuropeptide Systems as Targets for Parasite and Pest Control written by Timothy G. Geary and published by Springer Science & Business Media. This book was released on 2011-01-13 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need to continually discover new agents for the control or treatment of invertebrate pests and pathogens is undeniable. Agriculture, both animal and plant, succeeds only to the extent that arthropod and helminth consumers, vectors and pathogens can be kept at bay. Humans and their companion animals are also plagued by invertebrate parasites. The deployment of chemical agents for these purposes inevitably elicits the selection of resistant populations of the targets of control, necessitating a regular introduction of new kinds of molecules. Experience in other areas of chemotherapy has shown that a thorough understanding of the biology of disease is an essential platform upon which to build a discovery program. Unfortunately, investment of research resources into understanding the basic physiology of invertebrates as a strategy to illuminate new molecular targets for pesticide and parasiticide discovery has been scarce, and the pace of introduction of new molecules for these indications has been slowed as a result. An exciting and so far unexploited area to explore in this regard is invertebrate neuropeptide physiology. This book was assembled to focus attention on this promising field by compiling a comprehensive review of recent research on neuropeptides in arthropods and helminths, with contributions from many of the leading laboratories working on these systems.

Download or read book Hormone Signaling written by Vincent Goffin and published by Springer Science & Business Media. This book was released on 2002-03-31 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multicellular organisms require a means of intracellular communication to organize and develop the complex body plan that occurs during embryogenesis and then for cell and organ systems to access and respond to an ever changing environmental milieu. Mediators of this constant exchange of information are growth factors, neurotransmmitters, peptide and protein hormones which bind to cell surface receptors and transduce their signals from the extracellular space to the intracellular compartment. Via multiple signaling pathways, receptors of this general class affect growth, development and differentiation. Smaller hydrophobic signaling molecules, such as steroids and non-steroid hormones, vitamins and metabolic mediators interact with a large family of nuclear receptors. These receptors function as transcription factors affecting gene expression, to regulate the multiple aspects of animal and human physiology, including development, reproduction and homeostasis. The aim of this book is to cover various aspects of intracellular signaling involving hormone receptors.
