p21-deficient splenocytes were more susceptible to x-ray-induced apoptosis. Mice were exposed to 1 Gy of x-rays and were sacrificed 6 hours later for the collection of splenocytes. Terminal deoxyribonucleic transferase mediated dUTP nick end labeling (TUNEL) assay was performed to determine the level of apoptosis (N= 3 mice /group).
