The Denu Lab @ Wisconsin Institute for Discovery

The "Histone Code"

The University of Wisconsin - Madison

The Denu Laboratory investigates the mechanism and biological function of reversible protein modifications involved in modulating signal transduction, chromatin dynamics and gene activation.

The Denu Lab investigates the intersections between metabolism and the epigenome, a complex series of modifications made on top of the genome that regulates gene expression. Cell metabolism includes the many biochemical reactions that create energy and build crucial molecules for the cell. Epigenetics is the study of modifications to the DNA and histone proteins, which package DNA in the nucleus. Merging these two concepts, we study how the daily workings of the cell affect the folding and accessibility of DNA, influencing how our cells and ultimately body responds to changes in diet or lifestyle. Our interdisciplinary approach spans basic biochemistry to big data, using methods ranging from in vitro enzyme assays to high-throughput mass spectrometry. The Denu lab is part of the Microbiome, Epigenetics, and Multi-omics hubs at the Wisconsin Institute for Discovery, and is involved in many collaborations both on and off campus.
