MYC and neoplasm: Comparison of the lung tumour burden in Ad-CRE induced lsl-KRasG12D/+ (K), lsl-KRasG12D/+; Rosa26DM.lsl-MYC/+ (KM), and lsl-KRasG12D/+; Rosa26DM.lsl-MYC/lsl-MYC (KM2), mice at 6 weeks post induction (PI) revealed a dramatic, MYC-dose dependent, increase in the percentage of lung area occupied by tumours (Figure 1C).
