Epigenetic mechanisms in biology
Epigenetics describes inherited and acquired modifications of DNA, histones and proteins, which play critical roles in the regulation of gene expression, in chromosome stability, genomic imprinting, and stem cell fate. Alterations in epigenetic signaling are involved in major diseases including cancer, metabolic and neurodegenerative diseases. A dissection of the molecular mechanisms of epigenetic signaling will be facilitated by the widespread availability of small molecule chemical probes that are selective for specific components of the epigenetic machinery. Chemical probes will complement knockouts and RNAi approaches to dissect these biological networks.
In our group we focus on three areas of relevance- understanding structural and functional features of protein e.g. histone methylation and recognition, as well as applying chemical biology to two areas of biomedical importance with respect to regenerative medicine approaches, namely inflammation and stem cell biology.
