Biliary copper excretion in man and the rat. 1977

D J Frommer

The form in which copper is bound in bile was studied in bile from patients with Wilson's disease, control subjects and rats. Bile was labelled with 64Cu. Sephadex column chromatography using gels G-200--G-10 showed a major 64Cu and protein peak of about 5,000 daltons and a minor peak of about 8,000 daltons. A high-molecular-weight peak (above 800,000 daltons) which was present when the eluting solution consisted of water or saline was shown to be an artefact which could be abolished by the addition of bile salt to the eluting solution. Bile from control subjects, Wilson's disease patients and from the rats behaved in the same manner binding copper to low-molecular-weight proteins. The relationship of these findings to the pathogenesis of copper retention in Wilson's disease is discussed.

UI	MeSH Term	Description	Entries
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D011506	Proteins	Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.

D003300	Copper	A heavy metal trace element with the atomic symbol Cu, atomic number 29, and atomic weight 63.55.	Copper-63,Copper 63
D006527	Hepatolenticular Degeneration	A rare autosomal recessive disease characterized by the deposition of copper in the BRAIN; LIVER; CORNEA; and other organs. It is caused by defects in the ATP7B gene encoding copper-transporting ATPase 2 (EC 3.6.3.4), also known as the Wilson disease protein. The overload of copper inevitably leads to progressive liver and neurological dysfunction such as LIVER CIRRHOSIS; TREMOR; ATAXIA and intellectual deterioration. Hepatic dysfunction may precede neurologic dysfunction by several years.
