^†followed for growth delay;

^‡harvested for tissue analysis;

^∫anesthetized with intraperitoneal ketamine and xylazine;

^ƒanesthetized with isoflurane;

^*one mouse moved out of treatment portal during CIT and was thus omitted all analyses;

^ˆtwo mice treated with 20 Gy X-rays succumbed prior to tumor quintupling and were thus omitted from the quintupling time analysis
