Characterisation of novel gene products that regulate phospholipid metabolism and lipid droplet formation in the yeast saccharomyces cerevisiae. This project aims to study gene products that control lipid storage in the form of lipid droplets. The biogenesis and composition of lipid droplets in plant seeds or algae determine the quantity and quality of oil/biodiesel production.
Genome wide screening for gene products that regulate the celluar dynamics of lipid droplets. Obesity is a pandemic that if not stopped, will lead to huge social and economic problems in Australia. In essence, the hallmark of human obesity is the accumulation of cellular lipid droplets. This research will benefit Australia by providing a fundamental understanding of how lipid droplets are formed. This will have immediate international impact at the scientific level and will also provide novel ta ....Genome wide screening for gene products that regulate the celluar dynamics of lipid droplets. Obesity is a pandemic that if not stopped, will lead to huge social and economic problems in Australia. In essence, the hallmark of human obesity is the accumulation of cellular lipid droplets. This research will benefit Australia by providing a fundamental understanding of how lipid droplets are formed. This will have immediate international impact at the scientific level and will also provide novel targets and strategies for treating obesity. The proposed study will also benefit Australian agriculture by providing strategies to improve oil production from plant seeds. Read moreRead less
New laser and mass spectrometry-based tools for comprehensive structural elucidation of lipids and their biomolecular interactions. Lipid-related disorders such as obesity, diabetes and heart disease are reaching epidemic proportions. We propose the development of specialised instrumentation to identify and quantify lipids (fats) in tissue and culture samples thus providing Australian scientists with unique capabilities to investigate the mechanisms of disease.
Developing next generation technologies for unmasking the lipidome. Recent discoveries suggest that the number and structural variety of lipids in nature may be far greater than previously imagined. This complexity arises from the presence of structurally similar, but functionally distinct, lipid isomers that are not readily distinguished using current lipidomics technologies. This project aims to develop unique instrumentation that combines ion mobility and mass spectrometry to enable the rapid ....Developing next generation technologies for unmasking the lipidome. Recent discoveries suggest that the number and structural variety of lipids in nature may be far greater than previously imagined. This complexity arises from the presence of structurally similar, but functionally distinct, lipid isomers that are not readily distinguished using current lipidomics technologies. This project aims to develop unique instrumentation that combines ion mobility and mass spectrometry to enable the rapid separation, identification and quantification of isomeric lipids. These next generation technologies will be deployed in the hope of unmasking the molecular diversity within the lipidomes of two important mammalian cell types, thus providing fundamental new insights into the structure and function of lipids within living systems.Read moreRead less
