Summary
Treatments for leukaemia (e.g. chemotherapy) severely deplete immune and blood cells from patients. Transplantation of new blood forming cells (blood stem cells) into these patients is essential, but challenges are faced with isolating sufficient numbers in ways that preserve their ability to reconstitute the blood post transplant. My research aims to advance understanding of current methods used to isolate these cells and ultimately to improve the success of blood stem cell transplantation.
Insights Into The Biology Of The Carcinogenic Blood Fluke, Schistosoma Haematobium – A First Response To The Wake-up Call

Summary
Schistosoma haematobium is a seriously neglected parasite that infects > 100 million people. Chronic infection severely affects the urino-genital system and causes malignant bladder cancer. Advanced technologies will be used to explore, for the first time, the molecular biology of this parasite, design new strategies to fight this insidious pathogen and understand how it induces cancer.

Summary
Alzheimer's disease (AD) is becoming more common with our growing aged population and currently no treatment exists that halts disease progress. The increasing health costs of AD underscore the need for development of any treatment that will slow or halt AD pathogenesis. By understanding the mechanisms of action of a drug [latrepirdine] that has recently shown some promise in phase II clinical trials, related drugs that are more specific and potent will be developed.

Summary
The human genome is constantly exposed to agents-chemicals that cause DNA damage. Some of these are generated during normal metabolism and are referred to as reactive oxygen species while others comprise damaging sunlight, radiation and a variety of chemical agents. These agents can lead to cancer and a range of pathologies to different tissues including deterioration of brain function. This project is designed to investigate these processes using a specific genetic disorder as a model system. T ....The human genome is constantly exposed to agents-chemicals that cause DNA damage. Some of these are generated during normal metabolism and are referred to as reactive oxygen species while others comprise damaging sunlight, radiation and a variety of chemical agents. These agents can lead to cancer and a range of pathologies to different tissues including deterioration of brain function. This project is designed to investigate these processes using a specific genetic disorder as a model system. This disorder is called ataxia with oculomotor apraxia type 2 or AOA2. This condition develops in the teenage to early twenties and as the name suggests is characterised by loss of control of gait together with difficulties of eye movement. It is due to reduced function of a particular region of the brain called the cerebellum responsible for controlling movement. We have initial data suggesting that cells from these patients are very sensitive to environmental chemicals and their capacity to carry out repair of damage to DNA is compromised. We will investigate the nature of the defect at the molecular level and establish the function of the protein defective in this syndrome. This information will be important to determining specific therapies for AOA2 patients and may also have relevance to other neurodegenerative disorders.Read moreRead less
