8-Hydroxydeoxyguanosine (8-OHdG) is now widely used as a sensitive marker of oxidative damage to DNA. When human granulocytes are stimulated with TPA, they release a large quantity of reactive oxygen species (superoxide, hydrogen peroxide) which might be expected to generate hydroxyl radicals (OH.) which in turn could produce 8-OHdG in the DNA. There had been considerable debate as to whether OH. is detectable in stimulated granulocytes; most workers now agree that none can be detected, unless… CONTINUE READING
