Download or read book Cystogenesis written by Jong Hoon Park and published by Springer. This book was released on 2016-10-12 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a highly prevalent hereditary renal disorder in which fluid-filled cysts are appeared in both kidneys. Main causative genes of ADPKD are PKD1 and PKD2, encoding for polycystin-1 (PC1) and polycystin-2 (PC2) respectively. Those proteins are localized on primary cilia and function as mechanosensor in response to the fluid flow, translating mechanistic stimuli into calcium signaling. With mutations either of PKD1 or PKD2, hyper-activated renal tubular epithelial cell proliferation is observed, followed by disrupted calcium homeostasis and aberrant intracellular cyclic AMP (cAMP) accumulation. Increased cell proliferation with fluid secretion leads to the development of thousands of epithelial-lined, fluid-filled cysts in kidneys. It is also accompanied by interstitial inflammation, fibrosis, and finally reaching end-stage renal disease (ESRD). In human ADPKD, the age at which renal failure typically occurs is later in life, however no specific targeted medications are available to cure ADPKD. Recently, potential therapeutic targets or surrogate diagnostic biomarkers for ADPKD are proposed with the advances in the understanding of ADPKD pathogenesis, and some of them were attempted for clinical trials. Herein, we will summarize genetic and epi-genetic molecular mechanisms in ADPKD progression, and overview the currently available biomarkers or potential therapeutic reagents suggested.
Download or read book The Biology of Cilia and Flagella written by M. A. Sleigh and published by Elsevier. This book was released on 2016-01-11 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Cilia and Flagella reviews advances in the study of cilia and flagella since 1928. This book focuses on four main topics—structure of cilia, factors that affect ciliary activity, movement of cilia and flagella, and coordination of beat of cilia. In these topics, this compilation specifically discusses the intracellular structures associated with ciliary bases; viscosity of the medium and ciliary activity, and energy relationships of cilia and flagella. The compounding of synchronously beating cilia, variations in shaft structure, and control of ciliary activity by the organism are also elaborated. This text likewise covers the determination of the rate of beat of cilia and root-fiber systems and coordination of ciliary beat. This publication is suitable for biologists and clinicians of other disciplines researching on the structure and physiology of cilia and flagella.

This book was released on 2008 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many vertebrate organ systems contain a specialized ciliated epithelium decorated with motile cilia, which produce a ciliary flow in order to move mucus or fluid across the tissue surface. Examples include the proximal airways of the respiratory tract, oviduct, ependyma of the brain ventricles and the embryonic node. The importance motile cilia function in these specialized tissues to organ function is evident from human diseases such as primary ciliary dyskinesia (PCD) or immotile cilia syndrome. Patients with PCD are prone to chronic respiratory infections, sinus infections, in 50% of cases have situs inversus and in rare cases exhibit hydrocephalus. This broad array of phenotypes due to ciliary dysfunction clearly shows the importance of ciliated epithelia to organismal survival. A great deal is known about ciliary flow and how it relates to tissue function in relation to disease states. However, much less is known about how such tissues are formed during development, and what factors control the formation of cilia in these tissues. In this work I first describe the morphogenesis of the ciliated external epithelium of Xenopus laevis embryos, a tissue that closely resembles the respiratory epithelium in form and function. Cells with motile cilia cover the Xenopus embryo in a characteristic spacing pattern. This pattern arises early in development when cells in the inner layer of the ectoderm are selected by Notch signaling to form ciliated cell precursors (CCPs) that then undergo radial intercalation into the outer epithelial layer to form ciliated cells. Inhibition of Notch signaling results in an overproduction of CCPs; while radial intercalation becomes limiting ciliated cells maintain their spacing in the epithelium. Transgenic and transplantation assays to mark ciliated cells and intercalating populations, respectively, indicate that intercalating cells are free to wedge basolaterally, but can only insert apically at vertices where multiple outer cells make contact, likely making apical insertion the rate-limiting step during radial intercalation. Ciliated cell spacing also appears to be influenced by several other factors including competition with intercalating non-ciliated cell populations for vertices, cell morphology, and limitations on apical insertion likely imposed by the outer layer. Suggesting that cells other than the ciliated cells themselves can affect the ciliated cell spacing pattern, and thus final tissue architecture observed in such an epithelium. In the second part of this dissertation I describe a role for FoxJ1, a forkhead transcription factor, in the specification of node-like cilia in Xenopus and zebrafish embryos. Monociliate cells at the embryonic node generate a leftward fluid flow responsible for left-right asymmetry breaking in mouse, fish and Xenopus embryos. These cilia share features of both primary sensory cilia and motile cilia found on multiciliate cells, but how these cilia are specified in relation to other cilia is unknown. Using knockdown by morpholino injection, I show that FoxJ1 plays a conserved role in basal body docking in multiciliate cells found on the external epithelium of Xenopus embryos. However, in contrast to results in the mouse, I also show that FoxJ1 is required for formation of the node-like cilia in Xenopus gastrocoel roof plate (GRP) and zebrafish Kupffer's vesicle. Additionally, I show that misexpression of FoxJ1 is sufficient to induce ectopic GRP-like cilia on the surface epithelial cells of Xenopus embryos. Microarray analysis further indicates that FoxJ1 can induce ectopic cilia formation by upregulating the expression of genes required for cilia structure as well as genes required for cilia motility. Together these results indicate that node-like cilia in Xenopus and zebrafish are likely generated using a genetic pathway similar to that used to specify cilia in multiciliate cells. The studies presented in this dissertation shed light on the both the morphogenetic events that underlies the formation of the ciliated external epithelium in Xenopus embryos, but also on the specification of two different cilia subtypes that form on the epithelia of developing Xenopus embryo.

Download or read book Atlas of Histology of the Juvenile Rat written by George A Parker and published by Academic Press. This book was released on 2016-05-04 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlas of Histology of the Juvenile Rat should be of interest to toxicologic pathologists, toxicologists, and other biological scientists who are interested in the histomorphology of juvenile rats. For several decades the laboratory rat has been used extensively in nonclinical toxicology studies designed to detect potential human toxicity of drugs, agrochemicals, industrial chemicals, and environmental hazards. These studies traditionally have involved young adult rats that are 8-10 weeks of age as studies are started. It is becoming increasingly apparent that children and young animals may have different responses to drug/chemical exposures, therefore, regulatory agencies are emphasizing toxicology studies in juvenile animals. While the histologic features of organs from young adult and aged laboratory rats are well known, less is known about the histologic features of organs from juvenile rats. Final histologic maturity of many organs is achieved postnatally, thus immature histologic features must be distinguished from chemical- or drug-related effects. While this postnatal organ development is known to exist as a general concept, detailed information regarding postnatal histologic development is not readily available. The Atlas includes organs that are typically sampled in nonclinical toxicology studies and presents the histologic features at weekly intervals, starting at birth and extending through postnatal day 42. Written and edited by highly experienced, board-certified toxicologic pathologists Includes more than 700 high-resolution microscopic images from organs that are typically examined in safety assessment toxicology studies Detailed figure legends and chapter narratives present the salient features of each organ at each time interval Figures are available for further study via Elsevier’s Virtual Microscope, which allows viewing of microscopic images at higher magnification Valuable resource for toxicologic pathologists who are confronted with interpretation of lesions in juvenile rats in situations where age-matched concurrent controls are not available for comparison, e.g., with unscheduled decedents Figures are available for further study on ScienceDirect with Virtual Microscope, which allows viewing of microscopic images at higher magnification
