RESEARCH INTERESTS:Epigenetic Modifications and Their Role in Cellular Memory and Cancer Epigenetic modifications, particularly DNA methylation and covalent histone modifications, play an important role in regulating chromatin dynamics and therefore have a significant impact on gene expression. Our lab is interested in how epigenetic-mediated dynamic changes in chromatin structure affect gene expression, cell lineage commitment and cancer development. Our long-term goal is to apply this basic research to studies of human diseases. I. The relationship between ATP-dependent nucleosome remodeling and histone deacetylation. This area of study focuses on the nucleosome remodeling and deacetylase complex NuRD which we have recently demonstrated also plays an important role in methylated DNA silencing. We use a combination of biochemical and mouse genetic approaches to understand its biological function and the underlying mechanism through identification of its target genes by a genome wide localization approach. Our recent studies have linked its function to the autoimmune disease Lupus.
