PhD, University of Toronto
At A Glance
- We are an interdisciplinary lab studying the structure, function and chemical modulation of proteins involved in epigenetics and nuclear signalling – cellular mechanisms that are disrupted in cancer and other diseases.
- We use structural biology and chemical biology approaches to understand how transcriptional and chromatin regulatory proteins recognize, interact with and signal to other molecular components of the cell.
- In conjunction with the Structural Genomics Consortium (SGC), we are using our protein structural information to develop new chemical genetic tools to define, perturb and manipulate essential functions of proteins involved in methylation dependent signalling.
Dr. Arrowsmith received her Ph.D. in chemistry from the University of Toronto and carried out postdoctoral research at Stanford University. She is the director of the Toronto Node of the Structural Genomics Consortium (SGC), Senior Scientist at the Princess Margaret Cancer Centre, and Professor of Medical Biophysics at the University of Toronto. Dr. Arrowsmith is an internationally recognized expert in cancer related structural biology & chemical biology and epigenetics. She has been the leader of the Toronto site of the SGC since its inception and coordinates the SGC’s epigenetic chemical probe program. Dr. Arrowsmith was co-founder of Affinium Pharmaceuticals, a structure-based biotech that developed an anti-MRSA antibiotic that recently completed successful phase IIa trials. She has served as a member of 18 scientific advisory boards, grant review panels and journal editorial boards since 2000, including current membership on the Board of Directors of Academic Drug Discovery Consortium (ADDC). Dr. Arrowsmith holds a Canada Research Chair in Structural Genomics at the University of Toronto, has published over 250 peer reviewed articles, with more than 60 of these published in the last 5 years, and is co-author of over 1800 3D protein structures in the Protein DataBank (PDB). Her current research focuses on structural biology and chemical biology approaches to understand how transcriptional and chromatin regulatory proteins recognize, interact with and signal to other molecular components of the cell.
We have made extensive contributions to the understanding of the structure and function of important human chromatin regulatory proteins that are key modulators of disease and/or potential therapeutic targets including, p53, USP7, WDR5, HDAC7, UHRF1, and EZH2.
Using our structural and biochemical expertise, we have developed a series of chemical probes (drug-like tool compounds) targeting epigenetic regulators that are being used widely by the research community to better understand human biology and disease, and to identify new therapeutic opportunities.
We recently developed a novel inhibitor of protein-protein interaction site of WDR5, a key component of several important chromatin regulatory complexes. This chemical probes was used to demonstrate that antagonism of WDR5 protein-protein interactions results in suppression of cell growth and viability in CEBPa mutant leukemia and in breast cancer cell lines with gain of function mutations in p53.
