979-Multi-Enhancer Oncogene Regulation

Paper Talk · May 16, 2026 · 19m

This research examines how lineage-determining transcription factors physically reshape chromatin to regulate essential oncogenes through multi-enhancer interactions. Using advanced optical chromatin tracing and protein degradation systems, the authors demonstrate that factors like EBF1 and TCF1 act as permeable barriers to cohesin, a motor protein that loops DNA. By restricting cohesin's movement, these factors promote the local centralization of distant enhancers and promoters within the cell's nucleus. This architectural shift facilitates the simultaneous engagement of multiple regulatory…
