Summary
Colon cancer is one of the leading causes of death of all cancers. Two molecular pathways have been independently implicated in colon cancer development. Emerging evidences suggest that the two pathways may work together in the colon polypus formation. This application will integrate two separate molecular causes to form a new coherent understanding of cancer development and offer new directions in development of novel colon cancer treatment.
This project aims to comprehensively evaluate the role of androgen receptor (AR) signalling in breast cancer by identifying changes in AR signalling and its role in an endocrine resistant setting. Understanding the changes in AR signalling in either treatment-naive or treatment-resistant context would better assist in the identification for opportunities to modulate AR signalling as a therapeutic target in breast cancer.
Overcoming Therapeutic Resistance In Pancreatic Cancer

Summary
Pancreatic cancers arise when abnormal cells grow out from otherwise normal tissue. The resulting tumours contain a number of different types of cells, some of which help the tumour to grow, and some of which fight the tumour. We are interested in understanding how soluble molecules called cytokines influence the cells that promote tumour growth and metastasis. In particular, we will test whether cytokine inhibitors can overcome tumour resistance to chemotherapy.
Cancer causes significant morbidity and mortality in Australia’s aging population. There is strong evidence that abnormal blood vessels in tumours limit drug access and drive metastases. We have identified a molecule which controls vessel remodelling in tumours. In this proposal we will study mechanisms on how the molecule itself is regulated with the aim to normalize blood vessels for improved therapy.
Identifying Novel Genome Instability Signatures In Cancer

Summary
Cancer is the single biggest clinical problem facing the world. An underlying hallmark of cancer is the accumulation of errors in the genetic information of a cell which arises through genomic instability. This research project aims to investigate novel molecules identified by our screening that function in response to genomic instability in cancer. This study is expected to define roles for each molecule in the maintenance of genomic stability and predict for patient diagnosis and outcome.
Control Of Organ Size And Cancer By The Hippo Pathway

Summary
The Hippo pathway is a key regulator of tissue growth. It was first discovered in vinegar flies and plays a similar role in mammals. We aim to define the mechanism by which the Hippo pathway controls tissue growth and cancer. These studies will be performed in flies and mammalian cell culture. Our studies will shed light on how tissue growth is controlled, and have the potential to inform the way that we treat human cancers and tissue growth disorders.
Investigating The Cellular Requirement For STIM1 Phosphorylation And Store-operated Calcium Entry Suppression During Mitosis: Roles In Development And Cancer

Funding Amount
$344,900.00
Summary
Cells are constantly interacting with and modifying their surrounding environment. The intracellular calcium signal is one mechanism cells use to translate signals from the microenvironment into cellular responses. This proposal seeks to explore why a key calcium signalling pathway, known as store-operated calcium entry, is specifically silenced during cell division, and to determine how reversing this inhibition affects cell division during normal development and in cancer.
Elucidating Crosstalk Between RhoGTPases And Polarity Proteins: The Interface Between Morphology, Immune Function And Cancer.

Funding Amount

Summary
Major breakthroughs in cancer and autoimmunity require understanding the molecular basis of by which cell behaviour is controlled. We now know the key molecular players, but still need to determine how they interact within the cell to develop the best treatments and diagnostics. Recent breakthroughs now enable us to “watch” molecular interactions within the cell. We will use these approaches to determine how a key molecular switch is regulated in immune cells and cancer cells.
Tyrosine Kinase Signalling Networks In Pancreatic Cancer: Relevance To Therapeutic Response And Biomarker Development

Summary
Pancreatic cancer is a devastating disease characterized by a lack of effective treatments and biomarkers that identify the best way to treat individual patients. By identifying a novel basis for pancreatic cancer subclassification using cutting edge techniques, we aim to identify therapeutic strategies that can be directed to pancreatic cancer patients in a subgroup-selective manner to ultimately lead to reductions in the morbidity and mortality associated with this devastating disease.
Determination of cellular mechanisms underpinning cancer cell metastasis through integrated in vivo imaging approaches. Understanding key steps that drive the spread of cancer is critical to improve current treatment strategies. Using cutting-edge imaging technology and in vivo model systems that mimic the disease, this project will pinpoint key events that are susceptible to drug intervention and identify new therapeutic targets.
