This project aims to investigate how the fundamental processes of cell division and cell death are controlled at the molecular level by protein degradation enzymes (known as ubiquitin ligases), and how these regulate cellular homeostasis. Using interdisciplinary approaches incorporating proteomics, biochemistry, and molecular cell biology, this project seeks to delineate the components of signalling pathways implicated in the degradation of proteins implicated in cell division and cell death. Expected outcomes include an increased understanding of how proteins are specifically selected for degradation. Protein degradation pathways operate with remarkable selectivity and this work is expected to illuminate the mechanisms of substrate targeting. The biochemical approaches will provide insight and impact in the areas of cell signaling, organelle biology and cell biology.Read moreRead less

Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the cr ....Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the crosstalk between organelles and the cytoskeleton. To date, the role of microtubules remains elusive. Using interdisciplinary approaches combining advanced imaging technology with novel cell biology methods, the project aims to uncover fundamental knowledge about how cells interact with their environment.Read moreRead less

The role of human single-stranded binding protein (hSSB1) in DNA damage repair and tumorogenesis. Cancer is a leading cause of disease related death world wide, accounting for over 13% of all deaths in 2007. Approximately 38,000 people died in Australia from cancer in 2005. Cancer results from a single cell losing a vital part of its genetic information, this results in the cell losing its normal programming and initiates a process of rapid growth and multiplication.

Cancer is a leading cause of disease related death world wide, accounting for over 13% of all deaths in 2007. Approximately 38,000 people died in Australia from cancer in 2005. Cancer results from a single cell losing a vital part of its genetic information, this results in the cell losing its normal programming and initiates a process of rapid growth and multiplication. This research project aims to look at the mechanisms that exist to prevent this initial loss of genetic material within an individual cell. It further aims to translate theses discoveries into the clinic, providing new tools for diagnosis and prognosis of specific cancers and to establish links with major pharmaceutical companies to develop novel anticancer therapies.Read moreRead less
