In addition to being at odds with the above-discussed role for Myc in the proliferation of fibroblasts and T-cells and numerous other cell types (154, 158, 191, 196, 203), these results also differ from studies in Drosophila and some cancer lines showing that cells expressing higher levels of Myc tend to outcompete those with low levels (243–245). This evidence concerns the gene MYC and cancer.
