Using the perfusion method, we compared the accumulation and flux of inorganic mercury (Hg) and methylmercury (CH 3 Hg) across the gills and intestine of the blue crab, Callinectes sapidus. The accumulation and transfer processes were studied for each form by exposing the organs in the presence of specific ligands and other metals. While binding of Hg and CH 3 Hg to organic ligands...
Transmembrane proteins of the ABC family contribute to a multiple xenobiotic resistance (MXR) phenotype in cells, driving the extrusion of toxic substances. This phenotype promotes a high degree of protection against xenobiotics. The present study provides a better understanding of the MXR activity in the podal disk cells of Bunodosoma cangicum exposed to copper, and further establishes the relationship...
