From stress proteins to apoptosis and autophagy in sea urchin embryos

2019

Marine invertebrates inhabit a key position as intermediate consumers in the pelagic as well as in the benthonic food chains, making them suitable model systems for ecotoxicological studies. Among benthonic organisms, echinoderms represent a simple, though significant, model system to test how specific stress can simultaneously provoke dangerous effects on growth and vitality of organisms. Sea urchins provide an attractive and exceptional model for investigating environmental pollution. Most studies investigating the effects of Cd stress were conducted on Paracentrotus lividus, one of the most important marine invertebrates used as bioindicator of metal/heavy metal pollution and an importan…
