Project description:We examined gene expression profiling of native mussels that were sampled in early summer 2003 from sites of the Venice lagoon area known to be differently affected by chemical pollution: Sites 1 and 2 close to the industrial district of Marghera and Site 3 close to the Lido lagoon outlet. Site 4, a current mussel farm located offshore, has been chosen as source of reference targets for microarray hybridizations. We have limited the preliminary assessment to the digestive gland. Digestive gland total RNA of each Site was hybridized in competition with the offshore mussels (Site 4 - Reference) and the relative abundance of each gene was measured by directly comparing fluorescent signals for each probe. We carried out two separate hybridizations for each site of the Venice lagoon area..

Project description:A Ruditapes philippinarum microarray platform was developed to assess variations on transcritpomic response to copper exposures in Manila clam colelctted in Venice lagoon areas subjected to different anthropogenic impact
Project description:DNA microarray analyses of Ruditapes philippinarum sampled in Venice lagoon areas subjected to different anthropogenic impact. A comparative analysis of gene expression was conducted between Manila clam from lowly-polluted Chioggia and Colmata area and polluted Marghera site.
Project description:A manila clam oligo microarray platform (GPL10900) was used to profile gene expression in digestive gland of R. philippinarum sampled in four seasons in 4 different areas of Venice Lagoon. For each tissue, total RNA was extracted from four (4) independent biological replicates of digestive gland, each consisting of tissue pools of five (5) animals.
