Abstract
Previously, we reported that the stress-induced protein metallothionein I (MT) modulated the oxygen consumption (VO2) of isolated rat liver mitochondria [Life Sci. 55 221-226, 1994]. We now present confirmation of this finding, and the additional observations that in rat liver mitochondria, MT caused swelling and depolarization. These actions of MT were inhibited by the aliphatic polyamine, spermine. Our findings suggest that mitochondrial function could be influenced by the balance between MT and spermine.
