Multiplexed Molecular Reading of Protein Associations via Nanoscaled Devices. Current developments in Nanoscience and Nanotechnology hold many promises in terms of revolutionising our industrial base, transforming biology, medical science and practice.

Current developments in Nanoscience and Nanotechnology hold many promises in terms of revolutionising our industrial base, transforming biology, medical science and practice. This project strives to achieve some of these goals by, for the first time, building and testing nano-scaled devices with the capability to rapidly ?read? information about complex protein associations. With the recent completion of the Human Genome project, major opportunities exist to provide spectacular advances in human health care (eg, via novel diagnostics) provided that appropriate high-throughput biological reading devices can be developed. In developing such devices, this project also aims to catalyse the Australian Nanotechnology/Biotechnology industry.Read moreRead less
Regulation Of Hedgehog Signalling Through Intracellular Trafficking Events

Summary
The hedgehog signalling cascade plays a role in forming almost every organ of the body during development of an embryo. Perturbation of the function of key members of this pathway during embryonic development often results in death in utero or severe childhood abnormalities. In addition, disruption to this pathway also results in a range of cancers, most notably the extremely common skin cancer basal cell carcinoma. In this proposal we aim to investigate in detail the regulatory mechanisms which ....The hedgehog signalling cascade plays a role in forming almost every organ of the body during development of an embryo. Perturbation of the function of key members of this pathway during embryonic development often results in death in utero or severe childhood abnormalities. In addition, disruption to this pathway also results in a range of cancers, most notably the extremely common skin cancer basal cell carcinoma. In this proposal we aim to investigate in detail the regulatory mechanisms which operate to ensure that this complex pathway of interacting molecules functions correctly during embryonic development. By understanding how this regulation occurs we will gain valuable insight into how disruption of this pathway results in such a range of disease, as well as into how agents which modulate this pathway may potentially act in a therapeutic setting.Read moreRead less

Summary
A Cell Sorter Facility for Neuroscience and Related Biotechnology. Neuroscience is entering an era of accelerated discovery in which Queensland neuroscientists can excel if they gain leadership in key technologies. One critical technology is the ability to obtain specific cell populations from various parts of the nervous system in sufficient quantity and purity to enable their accurate examination by gene array, proteomics and physiological techniques. The aim is to establish the world's first ....A Cell Sorter Facility for Neuroscience and Related Biotechnology. Neuroscience is entering an era of accelerated discovery in which Queensland neuroscientists can excel if they gain leadership in key technologies. One critical technology is the ability to obtain specific cell populations from various parts of the nervous system in sufficient quantity and purity to enable their accurate examination by gene array, proteomics and physiological techniques. The aim is to establish the world's first cell-sorting facility dedicated to the production of nerve cells suitable for molecular characterization and screening, providing the basis for identifying key molecules regulating brain function, ageing and repair of great importance to the biotechnology/pharmaceutical industry.Read moreRead less
Escape From BRAF-induced Human Melanocyte Senescence In The Genesis Of Melanoma
Funder
National Health and Medical Research Council
Funding Amount
$601,776.00
Summary
Melanoma is the most lethal form of skin cancer and activation of the MAPK growth pathway is a crucial step in the initiation of this cancer, but alone is insufficient, as most melanocytes with active MAPK exist in a growth arrested state. The mechanisms responsible for arresting melanocytes in the presence of active MAPK will be investigated. This project will discover why some melanocytes develop into melanomas whereas most do not.
Prof Parton is a cell biologist studying how the plasma membrane functions in health and in disease. These studies have provided new insights into potential vehicles that can be used to introduce therapeutic agents into cells.
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
Identification of Proteins that Regulate Apoptosis Through Interaction With IAPS. Apoptosis is the process by which multicellular organisms eliminate unwanted cells. Identifying proteins involved in cell death regulation is central to our understanding of disease states arising from aberrations in this process. The mammalian protein DIABLO, promotes cell death by interacting with and antagonising inhibitor of apoptosis proteins (IAPS). Given the existence of several IAP regulatory proteins (IRPs ....Identification of Proteins that Regulate Apoptosis Through Interaction With IAPS. Apoptosis is the process by which multicellular organisms eliminate unwanted cells. Identifying proteins involved in cell death regulation is central to our understanding of disease states arising from aberrations in this process. The mammalian protein DIABLO, promotes cell death by interacting with and antagonising inhibitor of apoptosis proteins (IAPS). Given the existence of several IAP regulatory proteins (IRPs) in insects, other mammalian IRPs probably also exist. These may be of equal importance in regulating apoptosis, especially in tissues where DIABLO is not expressed. The main aim of the proposed study is to idenitify and characterise other IRPs in mammalian cells.Read moreRead less
