Uptake and efflux of copper-64 in Menkes'-disease and normal continuous lymphoid cell lines.
The accumulation of copper over 2 h by normal lymphoid cells and those from Menkes'-disease patients (Menkes' cells) was found to be biphasic, with an initial phase of rapid uptake, an approach to steady state at around 40-60 min, followed by a further accumulation phase. The accumulation of copper was not diminished by the addition of a variety of metabolic inhibitors, suggesting that copper u...
متن کاملA copper treatable Menkes disease mutation associated with defective trafficking of a functional Menkes copper ATPase.
Copper dependency in humans is most dramatically illustrated in Menkes disease, an X linked recessive copper deficiency disorder that is generally lethal in early childhood. 2 Menkes disease is caused by mutations in a transmembrane copper transporting P type ATPase, MNK (or ATP7A), which is expressed in virtually all non-hepatic tissues. Studies using cultured cells suggest that MNK is located...
متن کاملMenkes disease: a biochemical abnormality in cultured human fibroblasts.
Cultured skin fibroblasts from patients with Menkes disease, an X-linked disorder involving a defect in copper metabolism, were analyzed for copper concentration by means of atomic absorption spectrophotometry. These cultures consistently exhibited elevated copper concentrations (mean = 335.5 ng of copper per mg of protein) when compared to control fibroblast cultures (mean = 59.2 ng of copper ...
متن کاملCorrection of cerebrospinal fluid copper in Menkes kinky hair disease.
A patient with Menkes Kinky Hair disease was treated with infusions of copper-histidine which resulted in normal copper values in the cerebrospinal fluid. This tends to confirm the in vitro data that copper is transported into the central nervous system complexed with histidine or other similar ligands.
متن کاملDefective copper-induced trafficking and localization of the Menkes protein in patients with mild and copper-treated classical Menkes disease.
Menkes disease is an X-linked disorder of copper metabolism. An overall copper deficiency reduces the activity of copper-dependent enzymes accounting for the clinical presentation of affected individuals. The Menkes gene product (MNK) is a P-type ATPase and is considered to be the main copper efflux protein in most cells. The protein is located primarily at the trans -Golgi network (TGN), but r...
