Making muscle: molecular dissection of membrane domain formation. For a muscle to contract efficiently in response to an electrical signal it requires the formation of an extensive system of hollow membranous tubules through which the signal can be propagated. This proposal addresses the molecular mechanisms involved in the formation of this tubule system in skeletal muscle. This project will develop cell biology in a whole organism rather than a cell culture system and provide a new framework f ....Making muscle: molecular dissection of membrane domain formation. For a muscle to contract efficiently in response to an electrical signal it requires the formation of an extensive system of hollow membranous tubules through which the signal can be propagated. This proposal addresses the molecular mechanisms involved in the formation of this tubule system in skeletal muscle. This project will develop cell biology in a whole organism rather than a cell culture system and provide a new framework for Australian and international cell biologists. It will generate new knowledge, train young Australian scientists, help build international collaborative networks and engage the public outside the research community.Read moreRead less
Developing Novel Molecules That Target Hormone Receptors As An Alternative Cancer Therapy

Summary
A promising class of cancer drugs target heat shock protein 90 (Hsp90) and prevent Hsp90 from maintaining its ~100 proteins involved in cell growth. However, all current Hsp90 chemotherapeutics non-selectively target proteins maintained by Hsp90, and induce a cell rescue mechanism involving Hsp70. We describe the development of a novel molecule that will selectively control cell growth and prevent cell rescue via a unique Hsp90 regulated mechanism.
Characterisation of p14ARF intracellular trafficking pathways. Over 3500 new cases of melanoma are diagnosed in NSW each year, and one of the most important proteins involved in suppressing melanoma initiation or growth is p14ARF. This project will characterise the movement and functions of this protein with the aim of identifying novel targets for more effective drug therapies.
Understanding how Plasmepsin V directs export of malaria virulence proteins to the host cell. This project aims to characterise how malaria parasites survive and manipulate infected host cells by exporting virulence proteins. This project may identify essential proteins that allow the malaria parasite to transform the host in order to survive, replicate and hide from the immune system and provide new data on protein export in liver-stages.
Mechanisms Regulating Mitochondrial Outer Membrane Permeabilisation During Programmed Cell Death

Summary
Apoptosis is a form of cell suicide that is vital in human development and health by removing damaged or unwanted cells in a regulated manner. Disturbances in this pathway are known to be the cause of cancers and other diseases. This research will investigate how the pivotal step in cell death, termed mitochondrial outer membrane permeabilisation (MOMP) is regulated.

Summary
Electron microscopy cryopreparation facility for biomedical research. The proposed cryopreparation facility will allow cell and molecular biologists and material scientists in the region to prepare samples for ultrastructural research not currently possible due to insufficient local resources, and will thus significantly boost their research. The facility will support a wide range of world class medical and material scientists, including those visiting the Australian Synchrotron, whose research ....Electron microscopy cryopreparation facility for biomedical research. The proposed cryopreparation facility will allow cell and molecular biologists and material scientists in the region to prepare samples for ultrastructural research not currently possible due to insufficient local resources, and will thus significantly boost their research. The facility will support a wide range of world class medical and material scientists, including those visiting the Australian Synchrotron, whose research in health sciences and advanced materials characterisation facilitates the goals of promoting and maintaining good health and frontier technologies. The instrumentation will enhance training capacity in the region and provide young Australian scientists with direct experience of modern electron microscopy techniques.Read moreRead less
The Role Of A New Class Of Chromatin Organising Hub

Funding Amount
$1,145,450.00
Summary
Within the cell nucleus, specific proteins weave DNA into structured loops that are vital for normal cell function. By studying the molecules involved, we have uncovered a ‘dock’ that controls this DNA architecture. We will define the components and function of this ‘dock’, and the resulting rapid cell death that occurs if it is disrupted. We will explore this cell death pathway thoroughly because we think it may help us to develop new cancer therapies.
Caspase 8 Apoptotic Signalling Induced By The Inflammasome

Summary
The death of cells of our body can be an active and purposeful process. Programmed death occurs in response to infection or as a defence against cancerous changes. If a virally infected cell can die prior to replication of the virus, this will control the infection. We have investigated cell death in response to DNA found in the cytoplasm of cells, which can be an indication of infection. The novel cell death pathway we are characterising is relevant to defence against infection and tumours.

Summary
Impaired cell death (apoptosis) is now recognized as an important step towards cancer and a major barrier to effective therapy. The discoveries on apoptosis by Professor Jerry Adams and colleagues have galvanized the search for drugs that engage the cell’s apoptotic machinery as a new way to treat cancer. His proposed studies aim to clarify how apoptosis is controlled and how the control goes awry in cancer, and to determine how such drugs can be most effectively used to improve cancer treatment ....Impaired cell death (apoptosis) is now recognized as an important step towards cancer and a major barrier to effective therapy.

Role Of Bak And Bax Membrane Anchors In Targeting And Apoptotic Pore Formation.

Funding Amount

Summary
In cancer cells the normal process of cell death (called apoptosis) is defective, helping abnormal cells to grow and multiply unchecked. The Bak and Bax proteins are members of the Bcl-2 family of apoptosis regulators, and play a pivotal role in mediating cell death. By defining how these proteins form a pore in mitochondria, the point of no return in cell death, will help the development of novel anti-cancer agents that target the Bcl-2 family in general, and Bak and Bax in particular.
