Summary
FIH-1 is an oxygen-sensing protein expressed in every cell. The ability for cells to detect and respond to oxygen deficiency is necessary for survival in heart disease and stroke, and is also a feature of cancer. This research aims to characterise the role FIH-1 plays in normal development and disease using mouse and tumour model systems. This research could ultimately indicate whether FIH-1 is a feasible drug target.
Characterization Of A Novel Secretion And Attachment System Necessary For The Formation Of A Virulence Coat In Porphyromonas Gingivalis

Summary
In this study we will characterize a novel bacterial secretion system that we have discovered. This system mediates the secretion of proteins from the bacterial cell and their attachment to the cell surface. This system is essential for the virulence of a bacterium associated with severe gum disease. The chacterization of this system may offer opportunities for the development of new treatments to target this disease.

Summary
Formation and remodelling of the blood vessels is a critical feature of development. In addition, numerous disorders including psoriasis, arthritis, blindness, heart and brain ischemia, neurodegeneration, hypertension, pre-eclampsia, respiratory distress and osteoporosis among others are characterised by defective blood vessel patterning. The significance associated with understanding how Notch genes direct blood vessel formation is paramount, as this knowledge will inform future research.

Summary
The Signal Transducer and activator of transcription 3 (STAT3) protein is over-expressed or activated in most cancers. The paradigm for STAT3's role in cancer is that it drives the expression of genes which support tumour growth. Recently I found that STAT3 controls the altered metabolic state required for cancer progression, both by control gene expression and by entering the mitochondria. I propose define the mechanism of STAT3 mitochondrial activity and then translate these findings into anim ....The Signal Transducer and activator of transcription 3 (STAT3) protein is over-expressed or activated in most cancers.

Summary
Cholesterol has been shown to play a vital role in the life cycle of many viruses. This project will investigate the basis of dengue virus interaction with this important host molecule and along with investigations of how dengue is able to stimulate host cells, will provide new insights into the way these viruses cause severe disease. Findings from this study will also aid in the development of new drug strategies for dengue and related viruses such as West Nile virus.
