Metallothionein deficiency enhances skin carcinogenesis induced by 7,12-dimethylbenz[a]anthracene and 12-O-tetradecanoylphorbol-13-acetate in metallothionein-null mice.

Abstract excerpt

To clarify the physiological role(s) of metallothionein (MT) in carcinogenesis, we studied the susceptibility of MT-null mice to chemically mediated carcinogenesis in the 7,12-dimethylbenz[a]anthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA)-induced two-stage carcinogenesis model. The MT-null mice were subjected to a single topical application of DMBA (50 or 100 micro g/mouse) and, 1 week later, to...
