Abstract
Lysyl oxidase activity was measured in the lungs and from cultured fibroblasts of Blotchy mice. A marked decrease in lysyl oxidase activity was observed in lungs of affected mice as compared to normal litter mates. Fibroblasts cultured from Blotchy mice were also deficient in lysyl oxidase, producing less than half of normal enzyme levels. Normal and Blotchy fibroblasts which had been maintained in culture for several months and had undergone spontaneous transformation, continued to show the same magnitude of difference in lysyl oxidase levels. The data suggest that the deficiency of lysyl oxidase is inherent in Blotchy fibroblasts and support the idea that the deficiency of this enzyme is the metabolic lesion that leads to the connective tissue defects observed in these animals.
