The Microenvironmental Niche In Cancer Progression

Summary
It is well accepted that the cells in the local environment of cancers can help to promote the growth and spread of tumour cells. We have shown that a cell type known as the pericyte previously thought to be involved in controlling tumour expansion by affecting new blood vessel formation, may directly influence tumour growth, a notion that will be tested in human skin and ovarian cancer models. We will also test if pericyte markers can predict those cancer patients at greater risk of relapse.
For 60 years, we have had only 3 effective cancer treatments: surgery, radiation and chemotherapy, often used in combination.The last 5 years have produced a powerful fourth treatment: the patient's own immune system.The long standing collaborations and synergies of our multi-disciplinary teams have already underpinned many recent advances in immune-based therapies: we are now poised to develop several further immunotherapies and on track to test them in patients during the term of this grant.
RNA Polymerase I: A Novel Target In The Treatment Of MYC Driven Malignancies

Funding Amount
$605,963.00
Summary
Synthesis of ribosomes, the cellular protein synthetic machinery, is dysregulated during cancer leading to the hypothesis that it may be causative in the malignant process. This application will test this hypothesis using novel inhibitors or ribosome biogenesis in a mouse genetic model termed E�-MYC that faithfully that replicates human B-cell lymphoma. These studies will uncover novel mechanisms in malignant transformation and identify new therapeutics in the treatment of human cancer.
Structural And Biochemical Investigation Of The Bloom�s Complex, Defective In Bloom�s Syndrome

Funding Amount
$184,661.00
Summary
Bloom�s Syndrome is a rare inherited disorder that results in greater than 90% risk of developing cancer by the age of 25. The gene that causes Bloom�s Syndrome, called BLM, protects cells from cancer-causing mutations hence affected individuals develop the same types of cancers as the general population, only much faster. We will investigate the properties of the BLM gene product and understand how it protects us from cancer, and may influence some forms of cancer treatment.

Summary
Fluorescence microscopy with optical tweezers: imaging cellular responses. Life relies on the ability of our cells to receive and respond to signals with pinpoint accuracy, involving both chemical and mechanical signals. This equipment will allow scientists to expose cells to both types of signals and measure the response at an unprecedented level of accuracy for the first time.

Imaging cell and tissue architecture using confocal and super-resolution microscopy: This project aims to understand how the architecture of cells and tissues is controlled. This is because the organisation of biological space underpins the function of cells, tissues and organisms. This project will test the role of identified parts of cell architecture in regulating specific animal functions/pathologies. It will do this by using new microscope technologies which are at the frontier of visualising cell structure in isolation and in the context of tissue including application to the living animal. The dynamic organisation of structures in cells will be imaged in living tissue. Novel insights into structure/function relationships in the body will impact the health industry and generate opportunities for new diagnostics and therapeutics. Read moreRead less
A Transcription Factor Network Constraining The Development Of B Cell Leukaemia

Funding Amount
$617,531.00
Summary
B cell leukemias are relatively common, often aggressive hematopoietic malignancies and their cause is unknown in many cases. We have found that deficiencies in several transcription factors that normally control B cell differentiation cause B cell leukemias at a high frequency. We wish to identify the key pathways that are regulated by these factors and, in normal cells, prevent leukemic transformation. This will help to identify potential targets for therapeutic intervention.
Development and validation of virtual epithelial cancer models using an integrated modelling and experimental three-dimensional approach. The mathematical and experimental modelling of the human prostate and ovary applying quantitative bioengineering concepts will lead to virtual cancer models. This project aims to validate these multi-scale models to delineate biological and pathological avenues in healthy and disease tissue and improve prevention and treatment of prostate and ovarian cancer.
The Contribution Of Host Caveolin-1 To Breast Cancer Metastasis

National Health and Medical Research Council
Funding Amount
$517,992.00
Summary
Mortality in breast cancer rises to 80% in cases where secondary tumors form in other organs. To improve outcome, a better understanding of the processes involved in cancer spread is needed. Normal cells contribute to the growth and spread of a tumour and are a target for therapy. When a protein called caveolin-1 is lost from normal cells in a tumour, the prognosis for the patient is much worse. The aim of this project is to understand how this protein can regulate the spread of breast cancer.
The Role Of Clathrin In The Spindle Assembly Checkpoint And As An Anti-cancer Target

Funding Amount
$651,768.00
Summary
Cell division produces two daughter cells. Incorrect localisation and modification of proteins that regulate mitosis cause errors that can lead to cancer. As well as using a unique machinery mitosis uses proteins involved in non-cell cycle pathways. This project investigates the role during mitosis of one such protein: clathrin. We will identify lead clathrin inhibitory compounds, pitstops, that have potential anti-cancer properties, ultimately to be used as a chemotherapy agent.
