  • Title: [Thymidine excretion from thymocytes in irradiated and nonirradiated rats during endonucleolysis].
    Author: Konov AV, Vashchenkova II, Ivannik BP, Riabchenko NI.
    Journal: Radiobiologiia; 1987; 27(1):100-3. PubMed ID: 3029797.
    Abstract:
    The concentration of free thymidine (dT), excreted from thymocytes of irradiated and nonirradiated rats, was determined after incubation of cells in various digestive buffers. The release of dT from thymocytes depended upon the rate of DNA fragmentation in conditions of chromatin endonucleolysis. The increase in the thymidine content, in conditions of chromatin endonucleolysis in buffers containing no calcium ions, was only noted in thymocytes of exposed rats: this was the consequence of chromatin DNA damages already available in these cells.
