Academic Interests

We study the roles of the aryl hydrocarbon receptor (AHR) and its target gene, poly ADP-ribose polymerase 7 (PARP7/TIPARP), in normal physiology, metabolism, inflammation and cancer. Both proteins have important roles in regulating inflammation and immunity. In the context of cancer, AHR and PARP7 allow tumour cells to “hide” from the immune system giving them the opportunity to grow and proliferate. We are determining if inhibition of AHR or PARP7, alone or in combination with current immunotherapy treatments, reduces cancer growth and progression. We also study the AHR-PARP7 axis in chronic inflammatory diseases including obesity and atherosclerosis.

AHR and PARP7 regulate several metabolic and signalling pathways in response to cellular stress. Both proteins dampen inflammation and regulate immune signalling, which allow tumours to avoid immune regulation and proliferate. Recent studies show that small molecule inhibition of PARP7 or loss of AHR expression release the brake that cancer cells use to evade the immune system. By using cell biology, gene editing, genomics, and preclinical cancer models, we aim to determine the suitability of targeting AHR and PARP7 alone, in combination or with other immunotherapy treatments as new therapeutic options for cancer treatment.
