Alteration of gene expression is fundamental to many diseases. A better understanding of how epigenetic proteins affect diseases provides a starting point for therapy development and the discovery of new drug. Professor Paul Brennan research focusses on epigenetics: the mechanisms that control gene expression. He studies how chemical probes interfere with epigenetic enyzmes that can be targeted to treat various diseases. Epigenetics combined with disease biology will ultimately accelerate drug discovery.
