Cancer arises through a combination of common DNA mutations which are associated with very poor survival in certain cancers. However, the cause of these mutations was always believed to be external factors (eg. UV light, toxins), Our exciting preliminary results show internal molecules, called circular RNAs, can drive these mutations and this project will investigate how this occurs and study whether targeting these molecules can reduce the incidence of cancers.
Circular RNAs As Genome Destabilisers In Human Disease

Summary
Mutation of genes are hallmarks of both cancer and neurological disorders. My research group has identified roles for circular RNAs in both these processes. Now, we must close the loop by investigating the mechanism of these processes. This will inform not only why these genes are commonly mutated, but by exploiting the highly stable circular RNAs they may provide early prognostic/diagnostic biomarkers and even represent novel therapeutic targets for cancer and Huntington’s disease.
Targeting The Oncoprotein MDMX As A Novel Treatment For Triple Negative Breast Cancer

Summary
Breast cancer (BrCa) is a leading cause of cancer death in women worldwide. BrCas unable to respond to current therapies have the worst outcomes. We propose a novel strategy to treat these cancers, based on our new findings. Our two protein targets are: (1) MDMX, that we found drives BrCa with its partner, (2) mutant p53, which causes cancer spread. We plan to directly target these drivers of aggressive BrCas, using new drugs that individually show great promise in trials in a number of cance
Deciphering The Role Of DNA Methylation In The Regulation Of Alternative Splicing

Summary
When a gene is turned on, the messenger RNA must be correctly processed to generate functional proteins. This ‘splicing’ process is essential for normal cellular activity, and is disrupted in many human diseases. We have discovered that an epigenetic modification, DNA methylation (mC), may control splicing. This project will investigate how mC influences splicing and use new epigenome-editing tools to control it, in order to ultimately understand and treat diseases involving aberrant splicing.
