Inhibiting pathological signalling in haematopoietic disease. Certain leukaemias and other blood diseases are caused by the mutation of one particular molecule, called Janus Kinase (JAK), inside our bodies. This project aims to understand the biochemical details of these diseases by studying this mutated molecule in detail. The project will aim to provide the information for developing effective therapeutics against these diseases.
Regulation and function of a novel protein tyrosine phosphatase. A cell's ability to respond to its extracellular environment involves a complex and highly organised series of events referred to as cellular signalling. These signalling processes regulate fundamental cellular processes that underlie the growth and development of all living organisms. This proposal focuses on a group of enzymes known as the protein tyrosine phosphatases and their ability to regulate tyrosine phosphorylation-depe ....Regulation and function of a novel protein tyrosine phosphatase. A cell's ability to respond to its extracellular environment involves a complex and highly organised series of events referred to as cellular signalling. These signalling processes regulate fundamental cellular processes that underlie the growth and development of all living organisms. This proposal focuses on a group of enzymes known as the protein tyrosine phosphatases and their ability to regulate tyrosine phosphorylation-dependent signalling. We have identified a novel human protein tyrosine phosphatase and we aim to characterise its regulation and biological function.Read moreRead less

Biosynthesis, folding and modification of conotoxins. Disulfide-rich peptides represent a diverse family of bioactive molecules which have been developed as drugs for the treatment of severe pain. This project seeks to understand their biosynthesis and how their functional diversity is generated. Such information will assist the translation of more of these novel peptides into new drugs.
Structural and functional analysis of the protein kinase R. We have shown that protein kinase R (PKR) plays a key role in regulating the body's response to virus infections, inflammation and cancer. This project will identify mechanisms that regulate the activity of PKR and provide information useful for the development of novel drugs.
Studies of the pi3-kinase enzyme family using selective inhibitors. The objective of this project is to study the function of the PI3-kinase enzyme family in blood platelets. To do this, inhibitors which block the action of specific family members, will be evaluated for their effects in assays of platelet function. The results will enhance our understanding of the way in which platelets and other cells respond to stimuli, and lead new approaches to designing novel drugs that block these response ....Studies of the pi3-kinase enzyme family using selective inhibitors.

The discovery and characterisation of novel protein regulators of blood cell formation. All of the mature blood cells in the human body are derived from a common ancestor cell type known as a stem cell. Our proposed studies will enhance our knowledge of how functional, mature blood cells are formed from stem cells and how dysregulation of these normally tightly controlled pathways can give rise to severe blood diseases.
Regulation of neurite outgrowth by an inhibitor of PI3K signalling. PIPP is an enzyme which inhibits important cellular functions such as cell maturation. We have shown the amount of PIPP is increased in Alzheimer's disease brains. This project will characterise the mechanisms by which PIPP regulates brain cell function to identify how PIPP may be acting to exacerbate Alzheimer's disease development/progression.
Angiogenic defects in mutant growth plate cartilage reveal new modulators of vascular invasion. Converting cartilage to bone requires blood vessel invasion from the bony interface. This project will test, in vitro and in vivo, the hypothesis that collagen fragments regulate blood vessel invasion into cartilage. This data will have implications for processes requiring new blood vessels such as bone growth, cancer, inflammation and ischemia.
