title: Copper-thionein in melanoma.
abstract: The phenomenon of an elevated copper concentration in melanoma tumors was examined. It was demonstrated that 50-60% of total tissue copper is associated with metallothionein. The amino acid composition, electronic absorption and fluorescence were identical to that of the many known vertebrate Cu-thioneins. The immunological identification of melanoma tissue metallothionein was successful. The elevated Cu-thionein concentration in melanoma tumor tissue is not yet understood. It appears to be a common concept that in most tumors transient changes of the copper status parallel the metallothionein levels.
