Summary
The repair of DNA damage is a critical cellular mechanism that exists to ensure genomic stability. This project aims to investigate the role of the proteins Ena/VASP-Like and Protein Phosphatase 4C in DNA damage repair via homologous recombination. The DNA damage response pathway is an important area in the study of cancer and ageing, and the potential role of PP4C and EVL in homologous recombination needs to be investigated further.
Targetting The CIB1-sphingosine Kinase Interaction In Oncogenesis

Summary
Sphingosine kinase is a protein involved in cancer development and progression. We have identified that the cancer-inducing activity of sphingosine kinase is controlled by another protein called CIB1 which itself appears involved in causing cancer by deregulating sphingosine kinase. In this study we will examine and target the interaction between sphingosine kinase and CIB1 as a potential therapeutic intervention in cancer.
Only recently has it emerged that our cells have a built-in backup mechanism that instructs cells to die in extreme cases, such as when viruses have hijacked a cell. A misfiring backup mechanism is thought to underlie a number of human diseases, including inflammatory disease. Our investigation will establish a starting point for the development of novel anti-inflammatory drugs.
Cellular Regulation Of Receptor Signalling And Cytokine Responses

Summary
Cell surface receptors and signalling pathways elicit the release of cytokines, or chemical messengers, to control inflammation, which is the body’s response to infection or danger. We have discovered a new signalling pathway that can turn off inflammation and help prevent inflammatory disease. Our studies will now define the molecular details of this pathway and show how new and existing drugs targeting this pathway can be optimally used to treat inflammation and cancer.
Sphingosine Kinase As A Target For Anti-cancer Therapy

Summary
Sphingosine kinase is a protein involved in the development and progression of numerous types of solid tumors and leukaemias. We have recently made a major break-through by identifing how the cancer-inducing activity of sphingosine kinase is controlled. In this study we will target these control mechanisms to develop potential new anti-cancer therapies.
Why Is The Hijacking Of A Human Erythrocyte Signalling Pathway Essential For Malaria Infection?

Funding Amount
$510,890.00
Summary
Malaria drug resistance is spreading and the world needs cost-effective new drugs. We found 2 human enzymes, known targets of cancer chemotherapy, to be key for parasite survival in red blood cells. We aim to understand why these human proteins are crucial for the parasite and to identify new human proteins hijacked by malaria. This will open exciting options for antimalarial drug discovery: to harness funds invested in cancer drugs by targeting proteins with dual roles in cancer and malaria.
Understanding SOCS3 Inhibition Of JAK Activity In Myeloproliferative Disorders

Funding Amount
$524,820.00
Summary
The myeloproliferative disorders are diseases in which abnormal blood cell development leads to a risk of stroke, thrombosis, hemorrhage and leukemia. Remarkably, three of these disorders are caused by an error in a single enzyme that makes it over active. The enzyme, JAK2, controls how cells respond to hormone-like messengers called cytokines. We are investigating a cellular pathway that inhibits this enzyme in order to understand the progression and potential treatment of the disorders.
Understanding The Role Of The Atypical Cadherin Fat4 In Lymphatic Vascular Development

Funding Amount
$1,006,248.00
Summary
This application will define the role of a large cell adhesion molecule, FAT4, in lymphatic vascular development. By understanding how FAT4 functions in lymphatic vessels, we will gain insight to the mechanisms by which mutations in the gene that encodes this protein cause a human lymphoedema syndrome.
T cells play a central role in the immune response. The primary event in T cell activation is the triggering of a specific T cell receptor (TCR). Our studies will define new mechanisms for the regulation of TCR-mediated T cell responses. Our studies may yield novel insight into processes that contribute to the development of type 1 diabetes & inflammatory bowel disease.

Summary
Interrogating the adaptive potential of skeletal muscle. Disruptions to muscle oxidative capacity and growth signalling underpin atrophy and dysfunction with ageing, which impacts on an individual’s quality of life. These biological processes are thought to be mutually exclusive and compete during muscle adaptation. This project aims to define how these processes regulate the extent of muscle adaptation, and how modifying these attributes influence functional capacity in the context of ageing.

Disruptions to muscle oxidative capacity and growth signalling underpin atrophy and dysfunction with ageing, which impacts on an individual’s quality of life. These biological processes are thought to be mutually exclusive and compete during muscle adaptation. This project aims to define how these processes regulate the extent of muscle adaptation, and how modifying these attributes influence functional capacity in the context of ageing. This project will provide fundamental new knowledge in understanding how modifying muscle attributes influence successful ageing. This knowledge will improve resilience, productivity, and wellbeing of all Australians, with implications for reducing societal and economic burden.Read moreRead less
