Dossier Metallothioneins ■ Metallothioneins in the clam Ruditapes decussatus : an overview
The clam R. decussatus is a suspension-feeding bivalve mollusc widely distributed in European and Mediterranean coastal waters. Due to its economic importance it is extensively cultured in many countries, and particularly in Portugal where its production represents > 80 % of total shellfish production. The selection of the clam R. decussatus as a bioindicator was a consequence of its economic i...
متن کاملIsolation and characterisation of metallothionein from the clam Ruditapes decussatus.
Metallothioneins (MT) were obtained after purification from metal-exposed clams (Ruditapes decussatus) using gel-permeation and ion-exchange chromatography. Four cadmium-metallothioneins (CdMTs) were resolved by ion-exchange chromatography and they all had similar molecular weights, high cadmium content and an absorption spectra indicative of the presence of characteristic Cd-S aggregates. The ...
متن کاملHemocytes of the carpet shell clam ( Ruditapes decussatus) and the Manila clam (Ruditapes philippinarum): Current knowledge and future prospects
Hemocytes are the immune effectors in clams, directing cellular but also humoral defences. In the Manila clam (Ruditapes philippinarum) and the carpet shell clam (Ruditapes decussatus), two phenotypically similar venerid species, fishery and aquaculture importance motivated scientific studies to improve knowledge about the participation of hemocytes in immune response. Currently, gaps still per...
متن کاملA Microarray-Based Analysis of Gametogenesis in Two Portuguese Populations of the European Clam Ruditapes decussatus
The European clam, Ruditapes decussatus is a species with a high commercial importance in Portugal and other Southern European countries. Its production is almost exclusively based on natural recruitment, which is subject to high annual fluctuations. Increased knowledge of the natural reproductive cycle of R. decussatus and its molecular mechanisms would be particularly important in providing n...
متن کاملDifferential induction of glutathione S-transferases in the clam Ruditapes decussatus exposed to organic compounds.
Studies of glutathione S-transferase (GST) induction were performed in the Mediterranean clam Ruditapes decussatus after controlled exposure to organics in holding tanks. Clams were treated with phenobarbital (PB), benzo[a]pyrene (BaP), and 2,2-bis-(p-chlorophenyl)-1,1-dichlorethylene (p,p'-DDE). Three different substrates, i.e., 1-chloro-2,4-dinitrobenzene (CDNB), ethacrynic acid (ETHA), and p...
