MYC and lymphoma: In contrast to the significantly longer survival of mice receiving pre-neoplastic Eμ-Myc; Rock1 NC bone marrow (Fig. 7A), there was no difference in the survival of mice transplanted with Eμ-Myc; Rock1 WT (median survival of 20 days, maximum survival of 42 days) or Eμ-Myc; Rock1 NC lymphoma cells (median survival of 18 days, maximum survival of 38 days) (Fig. 7B).
