A positive feedback loop between Myc and aerobic glycolysis sustains tumor growth in a Drosophila tumor model.

abstract：:We previously showed in Drosophila melanogaster embryos that low-affinity Ultrabithorax (Ubx)-responsive shavenbaby (svb) enhancers drive expression using localized transcriptional environments and that active svb enhancers on different chromosomes tended to colocalize (Tsai et al., 2017). Here, we test the hypothesis...
