...Nataliya V. Dolgova; Doug Olson; Svetlana Lutsenko; Oleg Y. Dmitriev Wilson disease ATPase (ATP7B) has been implicated in the resistance of cancer cells to cisplatin. Using a simple in vivo assay in bacterial culture, in the present study we demonstrate that ATP7B can confer resistance to cisplatin...

... trophoblasts in culture, identify differential hormonal regulation of two copper-transporting ATPases; namely, those responsible for Menkes disease (ATP7A; MNK) and Wilson disease (ATP7B; WND). Insulin and oestrogen, which are essential during gestation, up-regulate MNK and this leads to trafficking of the MNK...

... in both Menkes and Wilson disease. The regulatory mechanisms of MNK and WND and their exact role in the placenta are unknown. Using a differentiated polarized Jeg-3 cell culture model of placental trophoblasts, MNK and WND were shown to be expressed within these cells. Distinct roles for MNK and WND...

...Michael A. CATER; John FORBES; Sharon La FONTAINE; Diane COX; Julian F. B. MERCER The Wilson protein (ATP7B) is a copper-transporting CPx-type ATPase defective in the copper toxicity disorder Wilson disease. In hepatocytes, ATP7B delivers copper to apo-ceruloplasmin and mediates the excretion...

... found in Wilson disease protein where several disease mutations cluster in it. In the present work, we have made a set of disease mutation analogues, including the mutants G503S (Gly 503 →Ser), G505R and A508F of ZntA. At low [ATP], these mutant ATPases are poorly phosphorylated. The phosphorylation...
