Summary
Skeletal muscle regeneration following injury is a tightly regulated process and any disturbance to this process, such as that which occurs with the muscular dystrophies, can greatly impair a muscle's ability to regenerate. The aim of this project is to better understand the mechanisms that control muscle regeneration, and open up new avenues for potential treatment strategies in conditions where muscle wasting and weakness are indicated.
Deciphering The Function Of Caspase-2 In DNA Damage Response And Tumour Suppression

Summary
Aberrant cell death and DNA damage response (DDR) are hallmarks of tumourigenesis. Recently we have discovered that an enzyme, caspase-2, previously implicated in cell death execution, also works in DDR and acts as a tumour suppressor. We now wish to validate these finding in preclinical models of cancer and understand precisely how caspase-2 safeguards against cancer development. These studies will help better understand tumourigenesis and may lead to the discovery of new drug targets.
Understanding The Molecular Mechanisms Of Cell Death In Radiotherapy

Summary
Radiotherapy (RT) is responsible for 40% of cancer cures. New technology enables RT delivery in fewer treatments using higher radiation dosages through a technique called 'ART'. While ART is effective in the clinic, the underlying mechanisms of cancer cell death are unclear. Here we show that ART induces two distinct waves of cancer cell death. We will characterize these waves of cell death and determine how to enhance tumour cell killing with pharmacological intervention.
Molecular Control Of Cell Proliferation In Early Mouse Development

Summary
Elucidation of cell cycle regulation in the proliferating pluripotent cells of the early mammalian embryo is likely to have important impact on basic scientific knowledge, and on the development of novel therapeutic strategies. Investigation of this problem, in vitro and in vivo, requires specialist skills in cell cycle analysis, and experimental manipulation of mammalian embryos and pluripotent cells.

Investigation of this problem, in vitro and in vivo, requires specialist skills in cell cycle analysis, and experimental manipulation of mammalian embryos and pluripotent cells. This application will seek to address these fundamental issues of early development and cell proliferation using molecular approaches. The general aims will be: 1. to obtain a detailed description of cell cycles in pluripotent and differentiating cells of the mouse embryo 2. use this information to build a molecular description of cell cycle events during early embryogenesis 3. investigate the relationship between rapid cell proliferation in the embryo and pluripotencyRead moreRead less
Novel Small Molecule FosB/AP-1 Inhibitors For The Prevention Of Proliferative Vascular Disorders

Summary
This project examines the effect of a novel FosB/AP-1 inhibitor (LK001) on neointima formation after injury in animal models of restenosis, atherosclerosis and abdominal aortic aneurysm, and a human ex vivo model of graft stenosis Given the current prevalence of CVD in Australia and the increasing demographic of susceptible individuals in the ageing population, this project has enormous clinical implications.
The Role Of Sidt2 In Cell Proliferation And Tumour Suppression

Funding Amount
$531,053.00
Summary
This project seeks to understand the function of a gene known as Sidt2. Our preliminary results suggest that Sidt2 not only controls how normal cells divide but also prevents cancer cell growth. We have now engineered mice that lack Sidt2, and will study the cellular and molecular pathways that are disrupted following loss of Sidt2. This work should provide important insights into how both normal and cancer cells grow, and will hopefully identify new targets for anti-cancer treatment.
