Role of Calcium Channels in Heavy Metal Toxicity
The role of voltage-dependent Ca channels (VDCC) in the membrane permeation of two toxic metals, lead (Pb) and cadmium (Cd), was studied in mammalian cells. Both metals interact with Ca-binding sites, but, while Cd influx appears to occur mainly through the same pathways as Ca, Pb is also rapidly taken up by different passive transport systems. Furthermore, I compared the effect of Cd in two Ch...
متن کاملHeavy Metal Toxicity
Heavy metals are metallic elements which have a high atomic weight and a density much greater (at least 5 times) than water. There are more than 20 heavy metals, but four are of particular concern to human health: lead (Pb), cadmium (Cd), mercury (Hg), and inorganic arsenic (As). According to the U.S. Agency for Toxic Substances and Disease Registry. These four heavy metals are four of the top ...
متن کاملHeavy Metal Toxicity
In general, irritable health concern related to heavy metal (accumulation) might be mainly divided into 2 types, i.e. heavy metal poisoning caused by excessive extrinsic exposure and genetic disorders such as Wilson disease (as reviewed by Osredkar et al. in this issue). As for the former type, unlike the latter one, it can be said that the health damage spread with the development of the civil...
متن کاملATTENUATION OF PARAQUAT TOXICITY IN MICE
Paraquat (PQ) is a widely used herbicide. However, a large number of cases of accidental or suicidal poisoning from PQ has been reported. Membrane damage induced by lipid peroxidation, inactivation of protein or damage to DNA by radical formation have been suggested as toxicity mechanisms of PQ. In the present work, the effects of atropine, propranolol, procainamide and dipyridamole on PQ-...
متن کاملProteomics of heavy metal toxicity in plants.
Plants endure a variety of abiotic and biotic stresses, all of which cause major limitations to production. Among abiotic stressors, heavy metal contamination represents a global environmental problem endangering humans, animals, and plants. Exposure to heavy metals has been documented to induce changes in the expression of plant proteins. Proteins are macromolecules directly responsible for mo...
