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.

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 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. In this study, we analyzed 64 samples (pools of 5 digestive gland). Gene expression profiling was performed using the Agilent-027304 Ruditapes philippinarum Oligo Microarray platform (GPL10900) based on single-colour detection (Cyanine-3 only). Microarrays were scanned with Agilent scanner G2565BA (barcode on the left, DNA on the back surface, scanned through the glass) at a resolution of 5 microns; all slides were scanned twice at two different sensitivity settings (XDRHi 100% and XDRLo 10%); the scanner software created a unique ID for each pair of XDR scans and saved it to both scan image files. Feature Extraction (FE) 9.5 used XDR ID to link the pairs of scans together automatically when extracting data. The signal left after all the FE processing steps have been completed is ProcessedSignal that contains the Multiplicatively Detrended, Background-Subtracted Signal.

Project description:Parasites of the genus Perkinsus spp. cause high mortalities and economic losses to the most noticeable bivalves produced in the worldwide aquaculture. In this study, we analyze how P. olseni influences the gene expression profiles of hemocytes from Manila clam (Venerupis philippinarum) using experimental infections along a temporal series and a Manila clam immune-enriched DNA microarray.

Project description:As a result of increasing thermal fluctuations and mean temperature values, organisms will experience conditions beyond their physiological limits. In situ adaptation to thermal regimes is mediated via directional selection and phenotypic plasticity. The latter involves physiological and morphological adjustments realized by underlying molecular mechanisms. Understanding species' adaptive capacities requires investigating these adjustive processes. Yet, acclimation through phenotypic plasticity remains largely unexplored, especially at the molecular level; For example, whether cold-adapted species inhabiting freshwater spring ecosystems have evolved adaptive mechanisms to cope with warming of freshwater habitats has, to our knowledge, never been investigated. This work reports a comprehensive proteomics study of the stenotopic species Crunoecia irrorata (Curtis, 1834) (Trichoptera: Lepistomatidae) acclimated to 10, 15 and 20 °C for 168 h. A liquid chromatography tandem mass spectrometry (LC-MS/MS)-based shotgun proteomics approach identified molecular mechanisms underlying acclimation. We constructed a homology-based database by combining genomic and transcriptomic data from related species and quantified 1356 proteins, of which 186 were differentially expressed between temperature treatments. Through functional annotation, we identified candidate proteins facilitating, among others, trehalose accumulation, tracheal system alteration, and heat shock protein regulation, then discuss concomitant ecophysiological implications. These results provide new insights into the mechanisms of adaptive responses to warming of species inhabiting freshwater ecosystems sensitive to climate change. Further, identified candidate proteins will aid in developing targeted experiments to understand their compensatory physiology. To our knowledge, this is the first study utilizing this approach to investigate the nature of phenotypic plasticity of aquatic macroinvertebrates.

Project description:Digestive Gland Samples: A manila clam oligo microarray platform (GPL10900) was used to profile gene expression in digestive gland of R. philippinarum. Total RNA was extracted from three (3) independent biological replicates of digestive gland for each sampling site, each consisting of tissue pools of five (5) animals. Statistical analysis with SAM (Significance Analysis of Microarray) identified1,127 probes differentially expressed. Gills Samples: A manila clam oligo microarray platform (GPL10900) was used to profile gene expression in gills of R. philippinarum. Total RNA was extracted from three (3) independent biological replicates of gills for each sampling site, each consisting of tissue pools of five (5) animals.
