Stress response induced by carbon nanoparticles in Paracentrotus lividus
Members of the 14-3-3 protein family are involved in many important cellular events, including stress response, survival and apoptosis. Genes of the 14-3-3 family are conserved from plants to humans, and some members are responsive to UV radiation. Despite the high rate of pollution generated by nano-pollutants, up to now is totally obscure their toxic effect on development. Embryos treated wit...

متن کاملSequence and expression of Paracentrotus lividus alpha tubulin gene.
In an effort to study the regulation of tubulin gene transcription during sea urchin embryogenesis we isolated several genomic and cDNA clones encoding for a and j3 polypeptides (1,2). Here we report the sequence of a full length a tubulin cDNA. Comparison of the predicted amino acid sequence of the cDNA clone (a 1 tubulin), shown in Fig. 1, with that of other clones encoding for a different a ...
متن کاملAsymmetrical localization and segregation of Paracentrotus lividus Bep4 maternal protein
Asymmetric divisions that produce two distinct cells play a fundamental role in generating different cell types during development. Here we investigate the role of the cortex region and mitotic apparatus in asymmetrical localization and segregation of Bep4 protein in Paracentrotus lividus egg. By centrifugation of eggs with or without drugs we established an involvement of the cortex region in ...
متن کاملEarly development and molecular plasticity in the Mediterranean sea urchin Paracentrotus lividus exposed to CO2-driven acidification.
Ocean acidification is predicted to have significant effects on benthic calcifying invertebrates, in particular on their early developmental stages. Echinoderm larvae could be particularly vulnerable to decreased pH, with major consequences for adult populations. The objective of this study was to understand how ocean acidification would affect the initial life stages of the sea urchin Paracent...
