Transcription factor nuclear residency as a driver of gene expression. Persistently active proteins can stay in the nucleus to drive cell growth and prevent cell death. This project will define how one specific active protein can remain in the nucleus and regulate gene expression through the action of unique ribonucleic acid (RNA) molecules. The results will enable persistent gene activation to be manipulated in cancer.
Characterisation of the oxygen-sensing asparaginyl hydroxylase, FIH-1, and hydroxylase-specific antagonists. This research will provide fundamental information on how cells and whole organisms can sense and respond accordingly to oxygen deficiency. This information is fundamental for our understanding of embryo development and adult life in different environments, and central to the diagnosis and treatment of diseases such as stroke, cardiovascular disease, and cancer.

This research will provide fundamental information on how cells and whole organisms can sense and respond accordingly to oxygen deficiency. This information is fundamental for our understanding of embryo development and adult life in different environments, and central to the diagnosis and treatment of diseases such as stroke, cardiovascular disease, and cancer. This research will contribute to our basic knowledge of these processes, provide invaluable information about the specific genes and proteins involved, and provide direct information about the therapeutic potential of specific drugs or inhibitors designed to target this oxygen response in human disease.Read moreRead less
Regulatory mechanisms for calcium release-activated calcium channels. Store-operated calcium channels play a central role in the functions of all animal cells. They participate in generating the cellular responses to hormones, growth factors and other physiological stimuli. The aims of this project are to elucidate the mechanisms that regulate the activity of store-operated channels and how their properties can be modulated by different pharmacological agents. Using chiefly the techniques of ele ....Regulatory mechanisms for calcium release-activated calcium channels. Store-operated calcium channels play a central role in the functions of all animal cells. They participate in generating the cellular responses to hormones, growth factors and other physiological stimuli. The aims of this project are to elucidate the mechanisms that regulate the activity of store-operated channels and how their properties can be modulated by different pharmacological agents. Using chiefly the techniques of electrophysiology and molecular biology we expect to learn the fundamental mechanisms that modulate the opening and closing of store-operated calcium channels and to gain an important information that can be used for determining the molecular structure of these channelsRead moreRead less

Second messenger-activated calcium channels in liver cells. This project concerns second messenger-activated calcium channels, part of the family of hormone-activated calcium channels which are essential to the functions of all animal cells. The aims are to elucidate the properties of a novel "large conductance" Ca2+ channel (using maitotoxin as an artificial activator), an inositol 1,4,5-trisphosphate-activated calcium channel, and the calcium channel formed by the transient receptor potential ....Second messenger-activated calcium channels in liver cells. This project concerns second messenger-activated calcium channels, part of the family of hormone-activated calcium channels which are essential to the functions of all animal cells. The aims are to elucidate the properties of a novel "large conductance" Ca2+ channel (using maitotoxin as an artificial activator), an inositol 1,4,5-trisphosphate-activated calcium channel, and the calcium channel formed by the transient receptor potential-1 (TRP-1) protein in hepatocytes. The electrophysiological properties, mechanisms of activation and intracellular trafficking of the channels will be investigated. It is anticipated the results will provide basic information on the physiological functions of second messenger-activated calcium channels. This will benefit the understanding of liver function, hepatotoxicity in animals, animal production and the development of pharmaceuticals in animal husbandary.Read moreRead less

Investigation of the fundamental roles of class Ib MHC (major histocompatibility complex) molecules in immunity. The proposed research program, using laboratory-based and synchrotron-based radiation, will provide insight into the roles of a poorly understood class of immune molecules. This will improve our understanding of the regulation of immunity, and the knowledge gained will increase Australia's international research profile.

This project aims to identify mechanisms via which the cytoskeleton regulates the branching of nerve cell extensions. The formation of branched cell extensions is essential for establishing a complex network of connecting and communicating nerve cells in all higher organisms. This project expects that by combining advanced light microscopy technology and recently developed tools for the study of the cell architecture in vitro and in vivo, we will be able to define the molecular changes in neurites that control neurite branching. This should provide significant benefits, such as gaining crucial insights into the mechanisms of forming complex neuronal networks.Read moreRead less
