Summary
The immune system can discriminate between invading microorganisms and the body's own tissues. Dendritic cells are specialised to alert the immune system in the case of infection. In this project we aim to understand how dendritic cells are generated and how they function to control the immune response. We will achieve this aim by using state of the art genomic technologies to describe the genetic programme of dendritic cells.

The Molecular Mechanisms Of Abscission To Complete Cytokinesis

Funding Amount
$380,558.00
Summary
Cytokinesis is the final stage of cell division that produces two daughter cells. Incorrect localisation and modification of proteins that regulate this process cause cell division errors potentially leading to cancer. This project will characterise how key cytokinesis proteins co-operatively function to complete cytokinesis. This research will increase our understanding of the cell division errors that contribute to cancer development, ultimately identifying new targets for cancer therapy.
Understanding The Biological Regulation Of MLKL And Its Role In Necroptotic Cell Death

Summary
Cell death is a normal process that permits the growth and defence of our vital tissues. One kind of cell death, necroptosis, is characterized by the swelling and bursting of cells. When cells ‘explode’ in this uncontrolled way they provoke an inflammatory response. This may be a factor behind illnesses ranging from colitis to cardiovascular disease. Understanding necroptotic cell death may pave the way for new therapies for those that suffer from these devastating conditions.
(Re)wiring A Stem Cell: Deciphering The Molecular Mechanism Underpinning Lineage Propensity

Funding Amount
$855,780.00
Summary
This project explores the response of the stem cells to cues that direct how they turn into specific type of cells that is suitable for clinical use. Specifically, a set of driver genes whose activity can foretell the outcome of cell differentiation will be identified. By modulating the maintenance conditions, iPSCs lines may be tailored for specific applications in stem cell therapy and disease modelling for the assessment of treatment efficacy.
Spatial And Temporal Aspects Of Epigenetic Remodelling In Cancer

Funding Amount
$626,707.00
Summary
Epigenetic deregulation occurs commonly in cancer, and can affect not only single genes but can encompass large chromosomal domains, leading to altered expression of oncogenes and tumour suppressor genes, and genomic instability. We will investigate the role of epigenetic remodeling, how spacial reorganisation of the genome, nuclear architecture, chromatin looping and replication timing may affect long range epigenetic deregulation, and ultimately contribute to cancer formation and progression.
Sickle cell anaemia and ?-thalassaemia are debilitating diseases for which there is no effective treatment. Patients require lifetime blood transfusions and drugs with significant side effects. These diseases are ameliorated in patients that express foetal haemoglobin into adulthood. The goal of this research is to understand how foetal haemoglobin is normally turned off at birth. This will ultimately help us discover how to switch it back on to treat patients.

Summary
Currently in Australia, it has been estimated that approximately 60 000 people suffer from chronic kidney failure (CKF). In at least 80% of people with CKF, the kidney function will continue to worsen (due to disease progression) to the point where end-stage kidney failure (ESKF) has developed. When the latter occurs daily treatment by either dialysis or kidney transplantation is mandatory for a person to survive. At present, there are nearly 10 000 patients with ESKF who are being treated by di ....Currently in Australia, it has been estimated that approximately 60 000 people suffer from chronic kidney failure (CKF). In at least 80% of people with CKF, the kidney function will continue to worsen (due to disease progression) to the point where end-stage kidney failure (ESKF) has developed. When the latter occurs daily treatment by either dialysis or kidney transplantation is mandatory for a person to survive. At present, there are nearly 10 000 patients with ESKF who are being treated by dialysis or transplantation, in Australia. Although these treatments have allowed patients to survive, they are associated with significant and unacceptable patient morbidity and mortality. Current medical treatments to reduce the disease progression of CKF (and thereby extend the time taken to reach ESKF) are non-specific, partially effective and have a variable response. Also, these treatments are NOT known to arrest the progression of CKF. To compound the overall problem even further, the number of new patients starting chronic dialysis programmes is increasing (by 6% per year). Consequently, ESKF has been described by leading authorities as a medical catastrophe of world-wide dimensions, and research into ways to reduce-arrest the progression of CKF has been recommended as an urgent priority by the Australian Kidney Foundation. In CKF, the kidneys undergo compensatory growth which is harmful and paradoxically contributes to disease progression. The aim of this research program is to advance knowledge about the molecular mechanisms of kidney growth in CKF, with specific goals of: (i) identifying new molecular targets for drug-based manipulation of kidney growth; and (ii) to test the efficacy of experimental drugs which have an ability to alter kidney growth, and thereby reduce the progression of CKF.Read moreRead less
