Therapeutic effects of tetrathiomolybdate on hepatic dysfunction occurring naturally in Long-Evans Cinnamon (LEC) rats: a bona fide animal model for Wilson's disease.
Long-Evans Cinnamon (LEC) rats were fed a diet containing 7 ppm Cu and 30 ppm Cu from 60 days after birth. Fischer (Fischer group) and LEC (LEC-control group) rats fed a 7 ppm Cu diet showed normal growth throughout the whole period (60 to 125 days after birth). On the other hand, LEC rats fed the 30 ppm Cu diet had decreased body weight and showed slight jaundice at around 100 days after birth. Tetrathiomolybdate (TTM, 10 mg/kg bw) was injected sub-cutaneously at 101 and 105 days after birth into half of the LEC rats fed the 30 ppm Cu diet. LEC rats given TTM (LEC+TTM group) recovered their body weight and the jaundice rapidly disappeared. However, LEC rats without TTM (LEC-TTM group) had sharply decreased body weight and showed severe jaundice at 103 days after birth. The hepatic Cu concentration in LEC+TTM rats (460 micrograms/g) exceeded that of LEC-control rats (330 micrograms/g) at 125 days after birth. Our data suggest that TTM is effective for treatment of acute hepatic injury in the LEC rat.

Selective removal of copper bound to metallothionein in the liver of LEC rats by tetrathiomolybdate.
LEC rats (Long-Evans with a cinnamon-like coat color) have a genetical defect in Cu metabolism. Male LEC rats aged 10 weeks were injected ip with TTM at a dose of 5 or 10 mg/kg body weight for 8 consecutive days and killed one day after the last injection. Cu that had accumulated in the liver at a concentration of 251 micrograms/g liver was decreased to 82.7 or 74.3 micrograms/g liver respectively, by the treatment. Although most of Cu was bound to MT as a soluble form before TTM treatment, the metal remaining in the liver after the treatment was present almost exclusively in the non-soluble fraction. Zinc (Zn) present, bound to MT before the treatment, was also partly removed from the liver by TTM, and the Zn remaining in the liver after the treatment was revealed to be bound to MT (Zn-MT) by high performance liquid chromatography-atomic absorption spectrophotometry. Iron (Fe) in the liver was not affected by TTM treatment. Cu in the kidneys and spleen increased by TTM treatment, while Zn and iron were not affected. Treatment of LEC rats with severe jaundice effectively cured the animals from otherwise lethal signs by only two ip injections of TTM at a dose of 10 mg/kg body weight.
