...K. M. Sterling; B. Roggenbeck; G. A. Ahearn SUMMARY This study describes the membrane transport mechanisms used by lobster ( Homarus americanus ) hepatopancreatic epithelial lysosomes to accumulate and sequester heavy metals from the cytosol, and thereby aid in the regulation of these ions entering...

...Kenneth M. Sterling; Prabir K. Mandal; Barbara A. Roggenbeck; Sean E. Ahearn; George A. Gerencser; Gregory A. Ahearn SUMMARY Crustacean hepatopancreatic lysosomes are organelles of heavy metal sequestration and detoxification. Previous studies have shown that zinc uptake by lysosomal membrane...

...) following exposure to various stresses (heavy metals and lipopolysaccharide), and correlates them with the variation in amount and time course of blood glucose. The dose-relationship between exposure to copper and quick release of cHH from the eyestalk into haemolymph was confirmed by variation of blood...

... % of the estimated amount of consumed zinc and copper in the abdomen of flies fed food containing several hundred parts per million dry mass of these metals. Our results are inconsistent with the detoxification hypothesis that predicts that a large proportion of the heavy metals passing through the gut are absorbed...
