Abstract
The present relates to methods for detecting DNA damage in subjects treated with an ATR inhibitor. More specifically, this invention relates to a method for measuring changes in levels of γH2AX and/or pChk1Ser345 in, e.g., surrogate tissue cells, following ex vivo stimulation with a DNA damaging agent.
Claims5
A method for monitoring DNA damage in a subject by measuring accumulation of γH2AX from blood, the method comprising:
- a) treating a subject with an ATR inhibitor;
- b) taking blood samples from the subject at various intervals;
- c) treating the blood samples with a DNA damaging agent;
- d) isolating white blood cells from the blood samples;
- and
- e) measuring γH2AX levels in the white blood cells by using antibodies specific for γH2AX.
