Stress biomarkers and alkali-labile phosphate level in mussels (Mytilus galloprovincialis) collected in the urban area of Venice (Venice Lagoon, Italy)

Induction of vitellogenin-like lipoproteins in the mussel Aulacomya ater under exposure to 17β-estradiol

“…The significant difference found between the ALP levels of males and females, mainly in the control and in the treatment with the lower E2 concentration, leads us to suggest the following hypotheses: (i) the higher level of ALP in males is explained by the lower levels of proteins in their gonads because they are in an earlier stage of gamete development, and (ii) males were induced by endocrine disruptors present in the natural environment. Other studies also reported the same situation: Matozzo & Marin (2005) for the clam Tapes philippinarum, Hashimoto et al (2000) for male flounder Pleuronectes yokohamae, and Pampanin et al (2005) for Mytilus galloprovincialis. In the last study the authors suggested that the presence of chemicals with estrogenic effect was probably able to induce the expression of the Vg-like proteins in males, whereas in females, where this protein is normally expressed during gametogenesis, the parallel process could be masked.…”

Evaluation of Multixenobiotic Resistance in Dreissenid Mussels as a Screening Tool for Toxicity in Freshwater Sediments

“…In addition to biotests, molecular and cellular biomarker responses have been successfully applied to evaluate the relevance of risks posed by complex contaminant mixtures well before implications would evolve at population and community levels (Cajaraville et al 2000;Behrens and Segner 2005). Within biomarker-based assessment schemes, analysis of biomarker responses in molluscs have been extensively used to evaluate site impact in freshwater and marine ecosystems both by active monitoring with transplanted mussels (Quinn et al 2004;Pampanin et al 2005;Guerlet et al 2007;Lekube et al 2014) and in laboratory tests (Eertman et al 1995;Binelli et al 2010;Sundt et al 2011). Typical ecotoxicological endpoints considered are usually cellular reactions (e.g, apoptosis), or-at a protein levelthe modulation of biotransformation and antioxidative enzymes.…”

Interspecific variability of endocrine disruption and oxidative stress in two bivalve species from the Ria Formosa Lagoon (south coast of Portugal)

“…Nevertheless, to our knowledge, this is the first study to report ALP concentrations in the gonads of M. galloprovincialis and R. decussatus. Other studies have determined ALP values in haemolymph (Pampanin et al 2005) and the digestive gland of the same mussel species exposed to different EDCs, and have reported a similar range of variation in field and laboratory experiments (Table 3). In other mussel species, M. edulis showed the same range of ALP concentrations in males but higher in females.…”
