Molecular Mechanisms of Toxicity of Silver Nanoparticles in Zebrafish Embryos
Silver nanoparticles cause toxicity in exposed organisms and are an environmental health concern. The mechanisms of silver nanoparticle toxicity, however, remain unclear. We examined the effects of exposure to silver in nano-, bulk-, and ionic forms on zebrafish embryos (Danio rerio) using a Next Generation Sequencing approach in an Illumina platform (High-Throughput SuperSAGE). Significant alt...
متن کاملToxicity of chlorine to zebrafish embryos.
Surface disinfection of fertilized fish eggs is widely used in aquaculture to reduce extraovum pathogens that may be released from brood fish during spawning, and this is routinely used in zebrafish Danio rerio research laboratories. Most laboratories use approximately 25 to 50 ppm unbuffered chlorine solution for 5 to 10 min. Treatment of embryos with chlorine has significant germicidal effect...
متن کاملComparative metal oxide nanoparticle toxicity using embryonic zebrafish
Engineered metal oxide nanoparticles (MO NPs) are finding increasing utility in the medical field as anticancer agents. Before validation of in vivo anticancer efficacy can occur, a better understanding of whole-animal toxicity is required. We compared the toxicity of seven widely used semiconductor MO NPs made from zinc oxide (ZnO), titanium dioxide, cerium dioxide and tin dioxide prepared in ...
متن کاملEffects of Nano Zinc Oxide on the Hind Limb Bud of NMRI mouse embryos
Nanomaterials are particles with 10 to100 nanometer size. They can easily be transportedthrough the skin, lung alveoli, and placenta. Materials in nano scales show different propertiescompared with the same materials in macro or larger scale. It is found that zinc element is anessential metal for normal physiological functions. However increase or decrease of this elementduring pregnancy, for e...
متن کاملInfluence of surface chemical properties on the toxicity of engineered zinc oxide nanoparticles to embryonic zebrafish
Zinc oxide nanoparticles (ZnO NPs) are widely used in a variety of products, thus understanding their health and environmental impacts is necessary to appropriately manage their risks. To keep pace with the rapid increase in products utilizing engineered ZnO NPs, rapid in silico toxicity test methods based on knowledge of comprehensive in vivo and in vitro toxic responses are beneficial in dete...
