Mechanistic bases of metal tolerance: linking phenotype to genotype
Ecotoxicology is currently undergoing a revolution as the result of new technological advances in molecular biology, capable of finely resolving metabolic mechanisms associated with exposure. These high-throughput analyses can detail the evolutionary and ecological implications of exposure in non-model organisms, such as the earthworm, Lumbricus rubellus. This terrestrial sentinel has been obse...
متن کاملPurification and characterization of six fibrinolytic serine-proteases from earthworm Lumbricus rubellus.
The six lumbrokinase fractions (F1 to F6) with fibrinolytic activities were purified from earthworm Lumbricus rubellus lysates using the procedures of autolysis, ammonium sulfate fractionation, and column chromatography. The proteolytic activities on the casein substrate of the six iso-enzymes ranged from 11.3 to 167.5 unit/mg with the rank activity orders of F2 > F1 > F5 > F6 > F3 > F4. The fi...
متن کاملEarthworm Lumbricus rubellus MT-2: Metal Binding and Protein Folding of a True Cadmium-MT
Earthworms express, as most animals, metallothioneins (MTs)-small, cysteine-rich proteins that bind d(10) metal ions (Zn(II), Cd(II), or Cu(I)) in clusters. Three MT homologues are known for Lumbricus rubellus, the common red earthworm, one of which, wMT-2, is strongly induced by exposure of worms to cadmium. This study concerns composition, metal binding affinity and metal-dependent protein fo...
متن کاملEvaluation of DNA damage and lipoperoxidation content in red earthworm, Lumbricus rubellus exposed to zinc oxide nanoparticles
Manufactured nanoparticles have a wide range of application due to their advantageous properties whencompared with their bulk forms. There is a growing concern regarding the safety of nanoparticles. This studyaimed to evaluate the cell membrane lipoperoxidation (LPO) and DNA integrity in red earthworm Lumbricusrubellus when exposed to artificial soil systems containing different concentration o...
متن کاملEarthworms and in vitro physiologically-based extraction tests: complementary tools for a holistic approach towards understanding risk at arsenic-contaminated sites.
The relationship of the total arsenic content of a soil and its bioaccumulation by earthworms (Lumbricus rubellus and Dendrodrilus rubidus) to the arsenic fraction bioaccessible to humans, measured using an in vitro physiologically-based extraction test (PBET), was investigated. Soil and earthworm samples were collected at 24 sites at the former arsenic mine at the Devon Great Consols (DGC) in ...
