title: Elevation of hepatic levels of metallothionein and zinc in mice bearing experimental tumors.
abstract: A tumor growth-dependent elevation in the hepatic levels of Zn and metallothionein (MT), without a change in the level of Cu, was found in mice and rats bearing solid tumors in the inguinal region. The levels of Zn and MT thus elevated gave a significant correlation (r = 0.95) between them. Nevertheless, when tumor-bearing mice and rats were fed a Zn-deficient diet, the hepatic levels of Zn and MT did not increase. In mice in which inflammation was induced at the same region, on the other hand, hepatic levels of Zn and MT increased transiently after the injection of turpentine or carrageenan even when they were fed the Zn-deficient diet. These results suggest that the elevation of MT and Zn levels can be a helpful marker for detecting malignancy.
