Topoisomerase activities and levels in irradiated Chinese hamster AA8 cells and in its radiosensitive mutant EM9.

International journal of radiation biology - 1 Aug 1999

Abstract excerpt

PURPOSE: To investigate possible variations in topoisomerase (topo) I and II activities and levels after X-ray treatment in the radiation repair proficient AA8 Chinese hamster cell line for comparison with the radiation sensitive mutant EM9. MATERIALS AND METHODS: AA8 and EM9 cells were irradiate...
