Sea urchin as in vivo model for the assessment of Manganese effect in embryos development

Sea urchin embryos as an in vivo model for the assessment of manganese toxicity: developmental and stress response effects.

Manganese (Mn), one of the most abundant metals in nature present in rocks, soil and water, is also found in soft bottom sediments of the oceans. It represents a trace element that is accumulated and utilized by all forms of life and plays multiple roles ranging from bone mineralization to cellular protection. Although Mn is an essential nutrient, exposure of cells/organisms to high levels of Mn cause toxicity. In the marine environment, increased concentrations of bio-available Mn often result from anthropogenic activities, and consequently, Mn represents a new important factor in environmental contamination. Emission of Mn into the marine environment occurs from metallurgic and chemical i…

TOXICITY INDUCED BY GADOLINIUM IONS ON DEVELOPING SEA URCHIN EMBRYOS

Pharmaceuticals are a class of emerging environmental contaminants. Gadolinium (Gd) is a metal of the lanthanide series of the elements whose chelates are commonly employed as contrast agents for magnetic resonance imaging, and subsequently released into the aquatic environment. We investigated the effects of exposure to sublethal Gd concentrations on the development of four phylogenetically and geographically distant species: two Mediterranean species, Paracentrotus lividus and Arbacia lixula, and two species living in the East coast of Australia, Heliocidaris tuberculata and Centrostephanus rodgersii. Measures of the Gd and Ca content inside embryos by ICPMS showed a time- and dose-depend…
