Exposure to cytotoxic concentrations of manganese and effects on development

2009

Manganese is one of the most abundant metals present in nature in trace amounts, which is accumulated and utilized by all forms of life. It plays a multitude of biological roles, but exposure of cells/organisms to high levels causes toxicity. In the marine environment, increasing concentrations of bio-available ions often result from anthropogenic activities, and, consequently, manganese represents a new emergent factor in environmental contamination. To study cyto-toxicity of manganese on development, we used an excellent model system as sea urchin embryos Paracentrotus lividus. In this work, we show results from two-dimensional gel electrophoresis (2DE) analysis that highlighted qualitati…
