The role of gamma glutamyl cyclotransferase in glutathione homeostasis. The aim of this study is to understand the structure and function of gamma-glutamyl cyclotransferase (GGCT) and its role in glutathione synthesis and turnover. Glutathione is essential for life and serves multiple biological functions protecting against oxidative stress, and aiding in the detoxification and excretion of foreign chemicals. This study will explore a new approach to changing intracellular glutathione concentra ....The role of gamma glutamyl cyclotransferase in glutathione homeostasis. The aim of this study is to understand the structure and function of gamma-glutamyl cyclotransferase (GGCT) and its role in glutathione synthesis and turnover. Glutathione is essential for life and serves multiple biological functions protecting against oxidative stress, and aiding in the detoxification and excretion of foreign chemicals. This study will explore a new approach to changing intracellular glutathione concentrations that has wide applications in the treatment of inherited enzyme deficiencies, cancer and the development of herbicide resistant crop plants. The study will also contribute to the training of scientists for the future development of the Australian biotechnology industryRead moreRead less
Discovering mechanisms of primary embryonic tissue migration through live cell imaging and novel genetic approaches. The studies proposed here will provide concepts and knowledge about the molecular basis of cell migration that will impact on diverse aspects of human health, such as the causes and nature of tumour metastasis and our understanding of the developmental basis of birth defects. In addition, understanding cell migration mechanisms will allow us to better predict or control the behav ....Discovering mechanisms of primary embryonic tissue migration through live cell imaging and novel genetic approaches. The studies proposed here will provide concepts and knowledge about the molecular basis of cell migration that will impact on diverse aspects of human health, such as the causes and nature of tumour metastasis and our understanding of the developmental basis of birth defects. In addition, understanding cell migration mechanisms will allow us to better predict or control the behaviour of therapeutic stem cells introduced into the body.Read moreRead less
Personalised Learning for Per-pixel Prediction Tasks in Image Analysis. AI-assisted image segmentation & synthesis are very challenging and usually require pixel-level labelling (per-pixel prediction) that is costly to obtain. The small amount of labels makes it difficult to train an “optimal” unified model for varied data as conventional methods did. This project aims to develop a new paradigm “personalised learning” to tackle this problem, where each image could be dealt with a model tailored ....Personalised Learning for Per-pixel Prediction Tasks in Image Analysis. AI-assisted image segmentation & synthesis are very challenging and usually require pixel-level labelling (per-pixel prediction) that is costly to obtain. The small amount of labels makes it difficult to train an “optimal” unified model for varied data as conventional methods did. This project aims to develop a new paradigm “personalised learning” to tackle this problem, where each image could be dealt with a model tailored to individual characteristics. The success of this project could significantly advance the fundamental research in image analysis. Expected outcomes include new knowledge and algorithms for image analysis, which could benefit fields like biology and archaeology, where labeled images are hard to attain and scarce.Read moreRead less
Cellular uptake of glutathione transferases and their development as cell transfection agents. The function and survival of all cells requires the importation of a vast array of biochemical agents. In order for this to occur, these agents must be transported across the cell membrane wall. We are investigating a novel delivery system involving the enzyme glutathione transferase (GST). By investigating how GSTs cross membranes, we will be able to develop a new technology for the delivery of bio ....Cellular uptake of glutathione transferases and their development as cell transfection agents. The function and survival of all cells requires the importation of a vast array of biochemical agents. In order for this to occur, these agents must be transported across the cell membrane wall. We are investigating a novel delivery system involving the enzyme glutathione transferase (GST). By investigating how GSTs cross membranes, we will be able to develop a new technology for the delivery of biologically active molecules into cells. This exciting new technique will have applications in research and in the delivery of therapeutic drugs for the treatment of a range of diseases. Read moreRead less
