Tamoxifen induces biochemical responses in Pacific oysters magallana gigas (Thu...

The activities of catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), glucose-6-phosphate dehydrogenase (G6PDH), and glutathione-S-transferase (GST) were evaluated in the gills (GI) and digestive gland (DG) of Magallana gigas oysters exposed to tamoxifen (TAM) at environmental concentrations of 10 and 100 ng L- 1 for 1 and 4 days. A higher CAT activity in the GI and DG and higher GPx activ...

Molecular and cellular effects of temperature in oysters Crassostrea brasiliana...

Exposure of aquatic organisms to polycyclic aromatic hydrocarbons (PAH), such as phenanthrene (PHE), may increase the production of reactive oxygen species (ROS) and cause changes in the biotransformation systems. In addition, changes in water temperature can cause adverse effects in the organisms. Estuarine species, like the oyster Crassostrea brasiliana, can adapt and tolerate temperature variation. To evalua...

Proteomic response of gill microsomes of Crassostrea brasiliana exposed to dies...

Diesel fuel water-accommodated fraction (diesel-WAF) is a complex mixture of organic compounds that may cause harmful effects to marine invertebrates. Expression of microsomal proteins can be changed by oil exposure, causing functional alterations in endoplasmic reticulum (ER). The aim of this study was to investigate changes in protein expression signatures in microsomes of oysterl Crassostrea brasiliana (=C.g...

In vivo effects of metals on the acetylcholinesterase activity of the Perna per...

It has been demonstrated that the enzyme acetylcholinesterase (AChE) is strongly inhibited by organophosphate and carbamate pesticides, and also by metals. However, recent reports indicate that some metals can activate AChE during acute exposure. In this work, we were interested in evaluating theeffect of trace metal exposure (12, 24, 72 and 120 h) on the AChE activity of Perna perna mussel’s digestive gland. M...

In this work, the levels of DNA damage (8-oxo-7,8-dihidro-2'-desoxiguanosina, 8-oxodGuo) were evaluated in digestive glands of mussels exposed to different metals for 24 hours, as well as in coastal and farmed mussels. These experiments were carried out in order to evaluate the influence of uncontrolled abiotic factors on the production of 8-oxodGuo in mussels, since such lesions are extensively used as an indi...
