Research Abstract
The Yokomori laboratory investigates the mechanisms of chromosome structural organization and how they affect DNA repair and gene regulation in human health and disease. Specifically, we use various DNA damaging methods, including laser microirradiation to study nucleus-wide epigenetic responses to complex DNA damage through PARP signaling and metabolic alteration. The mechanism and function of heterochromatin disruption in FSHD muscular dystrophy is another area of research, in which we perform single cell/nucleus analyses to isolate and characterize a small number of disease-driving cells and are developing 3D and tissue on a chip to measure intrinsic defects of FSHD and CRISPR-engineered mutant myocytes.
