Lim et al. (2018) use live imaging in Drosophila embryos to show that enhancers can drive transcription from promoters on another chromosome when they are in close proximity. In addition, they show that multiple promoters can access the same enhancer without competition, potentially sharing a pool of factors in a transcriptional "hub."
林等人（2018）利用活体成像在果蝇胚胎中表明，当增强子时与另一条染色体上的启动子接近时，它们可以驱动转录。此外，他们还表明，多个启动子可以在没有竞争的情况下访问相同的增强子，从而在转录“枢纽”中潜在地共享因子池。
