  • Title: [Change in the initiation of DNA synthesis on the nuclear matrix and its DNA-protein composition in gamma-irradiated hepatoma cells].
    Author: Kutsyĭ MP, Gaziev AI.
    Journal: Radiobiologiia; 1986; 26(5):668-71. PubMed ID: 3774979.
    Abstract:
    It was shown that gamma-irradiation of Zajdela hepatoma cells (10 Gy) induces inhibition of DNA synthesis initiation at a nuclear matrix and a change in its DNA-protein content. Irradiation of hepatoma cells with 10 and 50 Gy decreases incorporation of newly synthesized proteins in the firmly bound DNA-protein complexes of nuclear matrix. After 60-120 min postirradiation incubation of cells at 37 degrees C DNA-protein content of the nuclear matrix and its firmly bound DNA-protein complexes are restored. However the rate of DNA synthesis initiation being below the control level.
