Autophagic vacuole formation in mammalian skeletal muscle; role of FOXO proteins. Loss of muscle tissue is a hallmark of many common health problems including cancer, HIV-Aids and renal failure. Recently, we identified that a family of transcription factors termed the forkhead box class-O (FOXO) winged helix transcription factors are key regulators of both anabolic (building) and catabolic (wasting) signalling pathways. This project will investigate the molecular regulation of cell integrity by ....Autophagic vacuole formation in mammalian skeletal muscle; role of FOXO proteins. Loss of muscle tissue is a hallmark of many common health problems including cancer, HIV-Aids and renal failure. Recently, we identified that a family of transcription factors termed the forkhead box class-O (FOXO) winged helix transcription factors are key regulators of both anabolic (building) and catabolic (wasting) signalling pathways. This project will investigate the molecular regulation of cell integrity by FOXO proteins. Although very basic in nature, these projects will identify how FOXO proteins regulate muscle cell building and wasting and, therefore, present a potential therapeutic target for muscle wasting diseases, making this project highly significant.Read moreRead less
The MYB gene as a model for global transcriptional regulation: stopping, starting and looping. This project will study how transcriptional elongation controls the MYB gene, a key regulator of normal and cancerous growth and regulation. There are three major benefits that are likely to flow from the proposed research It will strengthen research in new and important areas of transcriptional regulation, by building research capacity in Australia in the area of gene expression, particularly with res ....The MYB gene as a model for global transcriptional regulation: stopping, starting and looping. This project will study how transcriptional elongation controls the MYB gene, a key regulator of normal and cancerous growth and regulation. There are three major benefits that are likely to flow from the proposed research It will strengthen research in new and important areas of transcriptional regulation, by building research capacity in Australia in the area of gene expression, particularly with respect to transcriptional elongation and long-range regulation. It will highlight a new approach to the therapeutic targeting of MYB in cancer: data generated from this research may enable us to target MYB expression in a range of cancers including breast cancer by inhibiting transcriptional elongation. And it will provide training in advanced molecular biology to postdoctoral scientists and students.Read moreRead less
Transcriptional and epigenetic regulation of terminal lymphocyte differentiation and alterations of the same that lead to leukemia. In the developed world infection diseases are the number three killer behind heart disease and cancer, and huge financial effort is put into treatment and prevention. Despite this, results have often been disappointing. One cause of these poor outcomes is the lack of knowledge of how effective immune responses are generated. This project aims to better understand th ....Transcriptional and epigenetic regulation of terminal lymphocyte differentiation and alterations of the same that lead to leukemia. In the developed world infection diseases are the number three killer behind heart disease and cancer, and huge financial effort is put into treatment and prevention. Despite this, results have often been disappointing. One cause of these poor outcomes is the lack of knowledge of how effective immune responses are generated. This project aims to better understand the processes that control the generation of protective lymphocytes. It will deliver information that may enable a more targeted approach to vaccine-development and treatments of infections. As defective differentiation can also be a cause of leukemia it may also lead to targets of cancer treatment.Read moreRead less
Identification of genes regulating breast cancer progression and metastasis. Breast cancer is the most common cause of cancer-related death in women in Australia. Although the treatments have improved over the last thirty years, many women still die from relapse of the disease. Our goal is to identify genes involved in the regulation of breast cancer progression and metastasis. This may lead to the discovery of druggable molecules for better targeted therapies for patients.
Rational structure-based drug design of protein tyrosine kinase inhibitors. Protein tyrosine kinases (PTK) are a large, pivotal family of signalling molecules implicated in diseases such as cancer and immune-related disorders, that cause significant morbidity and mortality within the population. This research proposal aims to develop PTK-specific small molecule inhibitors to combat such diseases. Cytopia's drug discovery capability, coupled with the X-ray crystallographic expertise within Monas ....Rational structure-based drug design of protein tyrosine kinase inhibitors.

This research proposal aims to develop PTK-specific small molecule inhibitors to combat such diseases. Cytopia's drug discovery capability, coupled with the X-ray crystallographic expertise within Monash University, will permit a rational, structure-based drug discovery platform to be established. The ultimate goal of this innovative and mutlidisciplinary approach, namely a portfolio of phase I therapeutics, will be of substantial benefit in the medical health area.Read moreRead less

Regulation and function of a novel protein tyrosine phosphatase. A cell's ability to respond to its extracellular environment involves a complex and highly organised series of events referred to as cellular signalling.
