Most of the genes repressed by Myc are involved in cell-cycle arrest, cell adhesion, and cell-to-cell communication.

http://medcell.med.yale.edu/lectures/cell_growth_control.php WebThe MYC gene is implicated in Burkitt's lymphoma, which starts when a chromosomal translocation moves an enhancer sequence within the vicinity of the MYC gene. The MYC gene codes for widely used transcription factors. When the enhancer sequence is wrongly placed, these transcription factors are produced at much higher rates.

WebMyc: Master Regulator of Cell Cycle Entry and Proliferative Metabolism. The Myc proteins (c-Myc, L-Myc, S-Myc, and N-Myc) are a family of transcription factors that regulate growth and cell cycle entry by their ability to induce expression of genes required for these processes (44 ). In normal cells, mitogen stimulation leads to a burst of Myc ... WebIn preclinical models, MYC inactivation can result in sustained tumour regression, a phenomenon that has been attributed to oncogene addiction. Many therapeutic agents that directly target MYC are under development; however, to date, their clinical efficacy remains to be demonstrated.
