I am a physiologist with expertise in endocrinology determining the roles of particular regulatory peptides in the normal functions of the gastrointestinal tract and in the development of gastrointestinal, renal and prostate cancers.
Mitochondrial Quality Control In Parkinson’s Disease: The Molecular Mechanisms Of PINK1 And Parkin
Funder

Funding Amount
$558,721.00
Summary
Parkinson’s disease is a degenerative disorder of the central nervous system in which the underlying cause is mostly unknown. To pave the way to a better understanding of what goes wrong, this study will investigate the function of PINK1 and Parkin, two genes that are mutated in inherited forms of the disease that play important roles in maintaining cellular health. The results of this study will be used in exploring new therapeutic targets for the treatment of Parkinson’s disease symptoms.
Molecular Characterisation Of The DBHS Proteins In Telomerase Assembly

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.
This project investigates the way in which viruses are able to use host cell machinery to make viral proteins and to replicate their own genetic material. We focus on the picornavirus family that cause illnesses with important health and economic consequences including serious heart infections such as myocarditis and pericarditis as well as the "common cold". This research we will reveal new possible avenues of antiviral development.
Structure And Function Of A Cancer-linked Co-regulator Complex

Funding Amount
$1,282,475.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
Molecular Dissection Of The Munc18c:Syntaxin4 Complex Required For Insulin-regulated Exocytosis In Adipocytes

Summary
When blood glucose levels are high, insulin signals to fat and muscle cells to remove glucose from the blood. The uptake of glucose relies on membrane fusion events that deliver a specific glucose transporter protein to the cell surface in response to insulin signals. This process is affected in Type II diabetes. Our research will characterise the regulation of these membrane fusion events and will be important for understanding how insulin signals are communicated in health and disease.
