Download or read book Oncogenic Mutation of GNAQ 11 Disrupts Melanocyte Biology in a Zebrafish Model of Uveal Melanoma written by Dahlia E. Pérez and published by . This book was released on 2016 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uveal melanoma (UM) is the most common primary intraocular cancer in humans. These tumors arise from nonclassical melanocytes found in the choroid, iris, and ciliary body (collectively called the uvea). Over 80% of UM tumors contain activating mutations in one of two genes encoding the homologous G[alpha] proteins GNAQ or GNA 11, which are the [alpha subunit of a heterotrimeric G protein receptor. Here we report that we have successfully used Tol-mediated transgenesis to develop a zebrafish model of UM driven by melanocyte specific expression of human oncogenic GNAQ/11Q 209L alleles. In cooperation with tp53M214K/M214K mutation, these GNAQ/11Q 209L transgenic zebrafish develop both uveal and cutaneous melanomas with nearly complete penetrance, causing early lethality. Furthermore, immunohistochemical analysis (IHC) reveals that these melanomas do indeed recapitulate the human disease in that they drive expression of oncogenic GNAQ and show increased expression of YAP. Interestingly, the transgenic zebrafish display an array of internal and external pigmentation defects compared to nontransgenic clutchmate controls. These pigment defects are independent of tp53 mutation. Zebrafish stripe patterning has been previously exploited to elucidate mechanisms in melanocyte signaling; therefore, to learn about the consequences of oncogenic GNAQ/1 1 signaling in melanocytes we pursued in vivo and in vitro study of transgenic melanocytes. The in vivo pigment phenotypes in these mutants include hyperpigmentation, mislocalized melanocyte and aberrant melanocyte morphology, and are detectable through all developmental phases beginning as early as 3 days post fertilization. In vitro, upon transgene expression the mutant melanocytes exhibit increased dendricity, motility, and survival. To understand the mechanisms underlying these phenotypes, we performed RNAseq on transgenic and nontransgenic melanocyte populations. Transcriptome analysis revealed a list of 353 differentially expressed genes. Functional analysis of this gene set implied changes in categories related to axon guiding, cell adhesion and cell cycle regulation. Taken together, our results reveal that persistent alterations in melanocyte biology occur as a result of oncogenic GNAQ/11 expression in a novel zebrafish model of UM. These observations provide the ground work for elucidating the mechanisms by which the oncogenic GNAQ/11 mutations are tumorigenic and for potentially generating therapies for this poorly understood disease.

Finally, all relevant clinical, radiological, and genetic investigations are described and important diagnostic issues are explored. Featuring numerous high-quality illustrations, the book will be of high value for all clinicians, researchers, and postgraduate students who deal with these malformations. The accompanying two volumes describe treatment principles and present in an atlas manner all relevant surgical techniques in detail. The content of this multivolume set, written by the world’s leading research and clinical specialists in their discipline, represents therefore the recent intellect, experience, and state of this medical field.

Download or read book Dento Oro Craniofacial Anomalies and Genetics written by Agnes Bloch-Zupan and published by Elsevier. This book was released on 2012-03-21 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental defects may be the physical expression of genetic defects, and so they can often be seen in a variety of syndromes associated with malformations of organs. However, dental defects are often not recognized, identified, nor characterised despite representing a possible diagnostic sign for an undiagnosed condition. This book addresses this gap by providing an understanding of dental genetics and its developmental biology counterpart. With approximately seventy well-illustrated examples, the authors present the clinical oro-facial manifestations accompanying various syndromes, providing the necessary knowledge for diagnostic purposes, as well as giving insight into recent development for each specific condition. The clarity and format of this book make it an ideal support guide both in the clinic and while conducting research. Comprehensive examination of dento/oro/craniofacial anomalies Well-illustrated examples Presented in a compact, easy to use format

Download or read book Veterans and Agent Orange written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-01-20 with total page 739 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1962 to 1971, the U.S. military sprayed herbicides over Vietnam to strip the thick jungle canopy that could conceal opposition forces, to destroy crops that those forces might depend on, and to clear tall grasses and bushes from the perimeters of US base camps and outlying fire-support bases. Mixtures of 2,4-dichlorophenoxyacetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), picloram, and cacodylic acid made up the bulk of the herbicides sprayed. The main chemical mixture sprayed was Agent Orange, a 50:50 mixture of 2,4-D and 2,4,5-T. At the time of the spraying, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most toxic form of dioxin, was an unintended contaminant generated during the production of 2,4,5-T and so was present in Agent Orange and some other formulations sprayed in Vietnam. Because of complaints from returning Vietnam veterans about their own health and that of their children combined with emerging toxicologic evidence of adverse effects of phenoxy herbicides and TCDD, the National Academies of Sciences, Engineering, and Medicine was asked to perform a comprehensive evaluation of scientific and medical information regarding the health effects of exposure to Agent Orange, other herbicides used in Vietnam, and the various components of those herbicides, including TCDD. Updated evaluations were conducted every two years to review newly available literature and draw conclusions from the overall evidence. Veterans and Agent Orange: Update 11 (2018) examines peer-reviewed scientific reports concerning associations between various health outcomes and exposure to TCDD and other chemicals in the herbicides used in Vietnam that were published between September 30, 2014, and December 31, 2017, and integrates this information with the previously established evidence database.
