Surprisingly, when adjusted for time post-tamoxifen injection, all four tamoxifen-treated CreERT2-p53F/F groups exhibited roughly the same median time to lymphoma formation and survival curves (p−2:0 = 0.140, p−2:+2 = 0.211, p−2:+4 = 0.696), considerably earlier than the control mice in which wildtype p53 was deleted, but without IR treatment (Fig. 2C,D). Here, TP53 is linked to lymphoma.
