Download or read book Motoneuron Dendrite Morphogenesis in Caenorhabditis Elegans written by Hannah Margareta Teichmann and published by Stanford University. This book was released on 2011 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nervous system function, from sensory perception to motor control and cognition, requires the correct wiring of neural circuits during development. The establishment of these circuits consists of the growth and guidance of signal-sending axons and signal-receiving dendrites to their correct targets. Despite being exposed to the same molecular environment, a neuron's axon and dendrites have different morphologies and targets. Using the C. elegans DA9 motoneuron we explore mechanisms of dendrite growth and how a dendrite-specific response is achieved to a cue regulating axons and dendrites. We found that DA9 dendrite development is spatially and temporally distinct from the axon. While the axon grows embryonically, the dendrite develops postembryonically. Characterizing DA9 dendrite growth in larvae, adults and body size mutants suggests that it is not driven by size, but rather by a local cue. A candidate approach to identify this cue taught us that the guidance cue UNC-6/Netrin is required for both axon and dendrite development in DA9. The UNC-6 repulsive receptor UNC-5 repels the axon from the ventral nerve cord, while the attractive receptor UNC-40 is dendritically enriched and promotes antero-posterior dendrite growth. While ventrally secreted UNC-6 instructs axon guidance, dorsal or even membrane-tethered UNC-6 can support dendrite development. Surprisingly, the kinase PAR-4/LKB1 is selectively required for UNC-40 signaling in dendrite outgrowth. Finally, we found that the C-terminal motor kinesin KLP-16 also promotes DA9 dendrite growth and that its enrichment at the DA9 dendrite distal tip may be partially regulated by PAR-4/LKB1. These data suggest that axon and dendrite of one neuron interpret common environmental cues with different receptors and downstream signaling pathways.

Book excerpt: The first of its kind, this laboratory handbook emphasizes diverse methods and technologies needed to investigate C. elegans, both as an integrated organism and as a model system for research inquiries in cell, developmental, and molecular biology, as well as in genetics and pharmacology. Four primary sections--Genetic and Culture Methods, Neurobiology, Cell and Molecular Biology, and Genomics and Informatics--reflect the cross-disciplinary nature of C. elegans research. Because C. elegans is a simple and malleable organism with a small genome and few cell types, it provides an elegant demonstr.
Download or read book The UNC 53 mediated Interactome written by Amita Pandey and published by Springer. This book was released on 2014-07-05 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an overview of various interactomes involved in dorsal ventral (DV) and anterior posterior (AP) guidance, their mechanisms of action, subcellular localizations, and functional roles. It will provide readers a better understanding of the development of the nervous system, which in turn will help to find cures to various neural and other disorders. In nematodes there are two types of guidance systems, including DV and AP guidance. The signaling process that guides the growth cones along the DV axis has remained intact in both vertebrates and invertebrates. The adaptor protein UNC-53 appears to play a part in migration along the AP axis in both worms and their human homologs. “Neuron Navigators” (NAV) are also involved in nervous system development
Download or read book Actin based Motility written by Marie-France Carlier and published by Springer Science & Business Media. This book was released on 2010-09-23 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of actin by Straub in the 1950’s and the pioneering work of Oosawa on actin self-assembly in helical laments in the 1960’s, many books and conference proceedings have been published. As one of the most essential p- teins in life, essential for movement in organisms rangingfrom bacteria to higher eukaryotes, it is no surprise that actin has fascinated generations of scientists from many different elds. Actin can be considered as a “living treasure” of biology; the kinetics and thermodynamics of self-assembly, the dissipative nature of actin po- merization, the molecular interactions of monomeric and polymerized actin with regulators, the mechanical properties of actin gels, and more recently the force p- ducing motile and morphogenetic processes organized by the actin nanomachine in response to signaling, are all milestones in actin research. Discoveries that directly derive from and provide deeper insight into the fundamental properties of actin are constantly being made, making actin an ever appealing research molecule. At the same time, the explosion in new technologies and techniques in biological sciences has served to attract researchers from an expanding number of disciplines, to study actin. This book presents the latest developments of these new multiscale approaches of force and movement powered by self-assembly processes, with the hope to opening our perspectives on the many areas of actin-based motility research.

Download or read book Centenarians A Model to Study the Molecular Basis of Lifespan and Healthspan written by Annibale Puca and published by MDPI. This book was released on 2021-06-15 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: People around the world are living longer. For the first time in history, most humans will live to be sixty and beyond. By 2050, the world's population aged 60 and over will reach a total of 2 billion, up from 900 million in 2015. Today, 125 million people are 80 years of age or older. By 2050, there will be 434 million people in this age group worldwide. In addition, the pace of aging of the world population is also increasing. However, there is not enough evidence to show that older people have better health than their parents. While rates of severe disability have declined over the past 30 years (but only in high-income countries), there have been no significant changes in mild to moderate disability over the same period of time. Indeed, the increase in the duration of life (lifespan) does not coincide with the increase in the duration of health (healthspan), that is, the period of life free from serious chronic diseases and disabilities. Therefore, the identification of the factors that predispose to a long and healthy life, as discussed in the papers of this book, is of enormous interest for translational medicine.

Download or read book Organogenetic Gene Networks written by James Castelli-Gair Hombría and published by Springer. This book was released on 2016-08-26 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: All animals, including humans, derive from a single cell, which possesses all the genetic instructions needed to define how the animal will look like. However, during development, the millions of cells that derive from the zygote will only select part of this genetic information to give rise to the various organs of the body. The coordination of different cell behaviours during development results in the formation of specialized tissues and organs giving rise to highly adapted animals. This book provides an overview of how this diversification is achieved during organ formation and how it may have evolved. Conserved cellular processes are presented using examples from selected vertebrate and invertebrate species that illustrate how developmental biologists are solving the complex puzzle of organ formation. This volume is aimed to students, researchers and medical doctors alike who want to find a simple but rigorous introduction on how gene networks control organ formation.“div> /div
