Activation of the Myc oncogene, too, is frequently seen in cancer, and inactivation of Myc results in tumor regression in many cancers through various mechanisms, which suggests to us inactivation of Myc cuts off the energy to fuel these mechanisms or simply cutting off fuel leads to proliferative arrest, senescence, apoptosis, interference with angiogenesis, and other mechanisms (reviewed in Felsher (198)). Here, MYC is linked to neoplasm.
