Abstract:
Hydroxyurea induces repair replication in human lymphoblastoid NC37 BaEV cells during incubation with liver microsomes and NADPH. Catalase reduces hydroxyurea-induced repair by more than 95%, suggesting that hydrogen peroxide derived from hydroxyurea in the presence of the metabolic activation system is involved in the DNA damage.
