Summary
The protein p97 takes part in the synthesis of cellular proteins from messenger RNA, a central step in gene expression. We will characterise p97 function as cells progress through their cycle of growth and division, and during responses to stress. Cellular stress is important in many diseases, such as viral infection, diabetes, heart disease, cancer, or complications during major surgery. Knowledge of p97 function may help us to better understand and treat these diseases.
Exploring Roles For MicroRNAs In Cancer Using Bioinformatics And Gene Expression Tools.

Summary
microRNAs are newly discovered chemicals that were the subject of the 2006 Nobel Prize in Medicine. These chemicals decrease the amount of specific molecular ‘targets’ in cells, and play an important role in cancer. Currently we do not understand how these chemicals choose their targets, and we propose to use a computer-based approach to discover how they affect genes in cancer. This will improve our understanding of cancer and thereby lead to the discovery of novel anti-cancer therapies.
I am a neuroscientist working on determining the different pathogenic mechanisms occurring in neurodegenerative movement disorders and dementias, and translating these findings for clinical neurologists and neuropathologists.
The cell is the building block of life. This proposal focusses on the surface of the cell, the plasma membrane, and specialised structures called caveolae that are an abundant feature of animal cells. Altered caveolae are a feature of many human disease conditions. In this proposal we will address the function of caveolae. We will test the idea that proteins are released from caveolae into the cell when cells are stressed forming a novel signalling pathway disrupted in disease.
Defining The Role Of A Palmitoylated Variant Of Sphingosine Kinase 1 In Cancer

Summary
Sphingosine kinase is a protein that when dysregulated is involved in cancer development and progression. We have recently made a substantial breakthrough in this area by identifing a naturally occuring variant of sphingosine kinase that is constantly activated and has an enhanced ability to induce cancer. In this study we will examine and target this form of sphingosine kinase as a potential therapeutic intervention in cancer.
