The c-Myc-related gene transcription network.

The transcription factor c-Myc (orange) is a cancerous protein that is also involved in metabolism and other processes in normal cells. The small molecule JQ1 inhibits the progress of cancers in mouse models by inhibiting both c-Myc itself and one of its coactivators (BRD4; green). More effective therapy could be achieved by targeting two or more molecules or processes in the network. For example, the different pathways that lead to the cancer (such as the Wnt and MAPK/ERK pathways) could be targeted, as could various cofactors (such as WDR5 and TBP) and different metabolic enzymes (such as PDK1, GLS1 and LDHA). In some cases, such as for some of the metabolic enzymes, small-molecule inhibitors are already known; in other cases, such inhibitors have not yet been discovered (indicated by question marks). Me and Ac represent methylation and acetylation. BRD4: bromodomain-containing protein 4. P-TEFb: positive transcription elongation factor complex b.
