报告摘要：
Understanding of the cancer epigenome brings great opportunities for therapeutic development. It remains challenging to probe how epigenetic enzymes write, read, and erase markers on both DNA and histones. My group is developing single-molecule methods to investigate epigenetics. I will first discuss how DNA methylation differentially regulates site-specific dissociation of conserved epigenetic enzymes on a CGI landscape. Next I will show how to investigate interactions between PHD3-Bromo of MLL1 and H3K4me3 using single-molecule force spectroscopy in a parallel DNA circuit. Finally I will demonstrate how to examine the dynamics of forming a triplex in an artificial telomere inferred by DNA mechanics. Our work is providing new methods for epigenetic studies and will facilitate the target-based drug development in future.
