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 کاملEquine Hepatic and Renal Metallothioneins
An improved, simplified, and greatly shortened isolation procedure for metallothionein from tissue extracts using gel filtration (Sephadex G-SO) and DEAE-cellulose chromatography is presented. When isolated by this procedure, the molecular weight of both the liver and kidney metalloproteins is found to be about 6600, as determined by equilibrium centrifugation and gel filtration. The amino acid...
متن کاملRole of metallothioneins in disease.
Metallothioneins are small proteins (6,000 to 10,000 mw) with similar amino acid compositions, high content of sulfhydryl amino acids and no aromatic amino acids. Emax at 250 nm is due to cadmium mercaptide bond. Synthesis is induced by a number of metals including zinc, cadmium, mercury, copper, bismuth, gold and silver. These proteins function as a mechanism of intracellular storage of some e...
متن کاملZeptomole Electrochemical Detection of Metallothioneins
BACKGROUND Thiol-rich peptides and proteins possess a large number of biological activities and may serve as markers for numerous health problems including cancer. Metallothionein (MT), a small molecular mass protein rich in cysteine, may be considered as one of the promising tumour markers. The aim of this paper was to employ chronopotentiometric stripping analysis (CPSA) for highly sensitive ...
متن کاملMetallothioneins in the lung cancer.
Metallothioneins (MTs) are low weight proteins involved in several key cellular processes such as metal ions homeostasis, detoxification and scavenging of free radicals. Four groups of MTs are distinguished: MT-1, MT-2, MT-3 and MT-4. Regardless of the type, MTs are characterized by high content of cysteine, responsible for their biological properties such as binding of relevant zinc and copper...
