Abstract/OtherAbstract:
Serum amine oxidase and/or porcine kidney diamine oxidase were trapped within reconstituted Sendai virus envelopes, and retained their activity. The trapped enzymes that were detected by radioimmunoblots were microinjected into cultured cells by fusion. When diamine oxidase was microinjected into cultured fibroblasts of chick or rat embryos, a temporary arrest in protein and DNA synthesis was observed. The inhibitory effect was more significant when both serum amine oxidase and kidney diamine oxidase were microinjected into those cultured cells. Fibroblasts of either chick or rat embryos transformed by Rous sarcoma virus were more susceptible to the injected enzymes than the normal cultures, showing a complete arrest in protein and DNA synthesis within 4 hours. Similar results were obtained by microinjecting diamine oxidase into cultured glioma cells. The injected enzyme catalyzed the oxidation of intracellular polyamines. The resulting oxidation product (hydrogen peroxide and aminoaldehydes) apparently caused the arrest in the synthesis of macromolecules.
