MYC and neoplasm: Comparison of the Am580 responders to the Myc-Ctrl group by Kaplan-Meier analysis showed that tumor latency in the responders was significantly extended (P = 0.0465, log-rank test, Am580 R vs. Myc-Ctrl), with 35% of the treated Am580-responding mice not developing tumors at 50 weeks (Figure 6B).
