p16INK4A expression inhibits the TAL1xLMO1-induced leukemogenesis. (A) Comparison of tumor susceptibility between TAL1xLMO1 mice (n = 25) and p16TLM mice (n = 15) and (B) between TAL1xLMO1 mice (n = 25) and LMO1xp16INKA mice (n = 23). Kaplan-Meier representations are shown. Survival rates are compared by the log rank test.
