WebInteractions among c-Myc, the E2F family, and the miR-17-92 cluster. (a) All interactions between the miRNA cluster and its transcription factors are illustrated.The entire network is composed of several feedback loops, e.g., the positive feedback loop E2F1 → E2F2 → E2F3 → E2F1 and the negative feedback loop E2F1 → c-Myc → miR-17-92 - E2F1. WebThe consequences of the coupling between the E2F/Myc positive feedback loops and the E2F/Myc/miR-17-92 negative feedback loop are analyzed using a mathematical model. The model predicts that miR-17-92 plays a critical role in regulating the position of the off-on switch in E2F/Myc protein levels, and in determining the on levels of these proteins. order by key array php
