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.. Keywords = digestive gland Keywords = Venice lagoon Keywords = chemical pollution Keywords = native mussels Keywords = transcriptional profiling Keywords: ordered
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:Monitoring microbial communities can aid in understanding the state of these habitats. Environmental DNA (eDNA) techniques provide efficient and comprehensive monitoring by capturing broader diversity. Besides structural profiling, eDNA methods allow the study of functional profiles, encompassing the genes within the microbial community. In this study, three methodologies were compared for functional profiling of microbial communities in estuarine and coastal sites in the Bay of Biscay. The methodologies included inference from 16S metabarcoding data using Tax4Fun, GeoChip microarrays, and shotgun metagenomics.

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.
