Summary
Telomerase is an enzyme that is active in over 90% of cancers. Telomerase activity allows cancer cells to divide an indefinite number of times. We have identified a novel role for the DBHS protein family in regulating telomerase activity. We aim to investigate the mechanisms by which these proteins function to assemble and transport telomerase to its site of action in the cell. We then aim to develop chemical inhibitors of these proteins, and test their utility in preventing cancer cell growth.
Cryo-EM Inspired Drug Discovery To Treat Human Fungal Pathogenic Infections

Summary
Invasive fungal infections are a major threat to global human health. These are highly prevalent in patients whose immune system is compromised (e.g. HIV, cancer or organ transplant patients). Of growing concern is the rise of new strains of fungal infections that are resistant to at least one of the four drug families being used to treat these infections. Here, we will create new therapeutics that block the activity of an enzyme whose activity is essential for the survival of these pathogens.
Exploiting Messenger RNA Export As A Novel Therapeutic Strategy To Treat Cancer

Summary
Novel therapies for cancers represent an area of unmet clinical need. We have identified a new biological pathway implicated in cancer, namely selective mRNA export. Compounds inhibiting other steps of the gene expression pathway are promising therapeutic candidates for cancer, yet mRNA export inhibitors do not exist. We propose to develop first-in-class inhibitors of mRNA export that selectively target transcriptionally addicted cancers with dysregulated RNA processing.
Pathways That Regulate Nuclear Export Of Circular RNA

Summary
An emerging and unusual class of RNA molecules, circular RNAs (circRNAs), is widespread and plays important roles in cancer initiation and progression. However, the pathways responsible for nuclear export of circRNAs are unknown. We propose here to systematically determine how circRNAs are exported from the nucleus and characterise the effect of modulating circRNA export pathways in cancer. This will enable us to determine whether circRNAs can function as a biomarker of patient response.
