Abstract: | Mitochondrial DNA synthesis in HeLa cells is inhibited by 0.2 μg ethidium bromide/ml whereas nuclear DNA synthesis is essentially unimpaired under the same conditions. The action of ehtidium bromide on mitochondrial DNA appears to be completed within 18 hours of exposure to the drug. Total cellular macromolecular synthesis under ethidium bromide is initially decreased and at later times slightly stimulated. Ethidium bromide pretreatment of HeLa cells did not significantly affect the multiplication of Herpes simplex virus as compared with that in control cells. |
