Project description:Transcriptional profiling of the mantle tissue across the four stages of male gonads development (winter peak) in a natural population of the marine mussel Mytilus galloprovincialis sampled in the Bizerta Lagoon, Tunisia, across November 2007 -March 2008. Background: Seasonal environmental changes may affect the physiology of Mytilus galloprovincialis (Lam.), an intertidal filter-feeder bivalve occurring commonly in Mediterranean and Atlantic coastal areas. We investigated seasonal variations in relative transcript abundance of the digestive gland and the mantle (gonads) of males and females. To identify gene expression trends, we used a medium-density cDNA microarray (1.7 K probes) in dual-color competitive hybridization analyses. Results: Hierarchical clustering of digestive gland microarray data showed two main branches, distinguishing profiles associated with the “hot” months (May–August) from the other months. Genes involved in chitin metabolism, associated with mussel nutrition and digestion, showed higher expression during summer. Moreover, we found different gene expression patterns in the digestive glands of males and females during the four stages of mussel gonadal development. Microarray data from gonadal transcripts also displayed clear patterns during the different developmental phases with peak relative mRNA abundance at the ripe phase (stage III) for both sexes. Conclusion: These data showed a clear temporal pattern in gene expression profiles of mussels sampled over an annual cycle. Physiological response to thermal variation, food availability, and reproductive status across months may contribute to variation in gene expression.

Project description:Sperm contains essential proteins for interaction with eggs, however, there are only several sperm proteins reported with important role in fertilization, and gamete proteomics are limited in marine invertebrate species. We present here a sperm proteomic profile of marine mussel Mytilus galloprovincialis. There are 816 proteins were successfully identified by LC-MS/MS based on 1-DE SDS-PAGE. Many of the identifications are relevant to sperm cell physiology and mtDNA functioning. The results will contribute to better understand the proteins involved in fertilization in M. galloprovincialis, as well as the other marine invertebrate species.

Mantle tissue from individual animals in different gonad maturation stages were analyzed in a complete loop design.

Project description:Pharmaceutical compounds are emerging contaminants in aquatic environment due to their massive use (human and veterinary medicines, agriculture and aquaculture) and a limited removal by waste water treatment plants (WWTPs). In this work, a representative determination of ecotoxicological potential of Ketoprofen s was studied in the sensitive bioindicator marine organism M. Galloprovincialis. Mussels were exposed, under regulated laboratory conditions, to Ketoprofen (KET) a, dosed alone at the realistic environmental concentration of 2.5µg/L for 14, 30 and 60 days. Gene expression analyses of Mytilus galloprovincialis exposed to KET have been performed trough a DNA microarray platform.
