Summary
Unique, state-of-the-art lipidomics infrastructure. The new technologies provided through this grant will significantly enhance our understanding of lipids and their role in normal cell biology and disease. These new insights will be vital in improving our understanding of lipid-related disorders such obesity, type 2 diabetes and cardiovascular disease and helping to improve their treatment and prevention.
Development of ozone-induced dissociation for lipidomics workflows. An Australian invention (ozone induced dissociation) will be developed in collaboration with a major instrument manufacturer. This project will provide Australian researchers with unique capabilities to investigate the role of lipids (fats) in human disease and will place them at the forefront of lipid research internationally.
Developing next-generation mass spectrometry imaging with isomer resolution. Mass spectrometry imaging (MSI) is a rapidly emerging technology for mapping molecular distributions within biological samples. This project will bring together market-leading MSI instrumentation from the industry partner Waters Corporation with unique technologies developed at QUT and UOW to develop an integrated MSI-platform capable of achieving high mass- and spatial-resolution, as well as discrimination of lipid iso ....Developing next-generation mass spectrometry imaging with isomer resolution. Mass spectrometry imaging (MSI) is a rapidly emerging technology for mapping molecular distributions within biological samples. This project will bring together market-leading MSI instrumentation from the industry partner Waters Corporation with unique technologies developed at QUT and UOW to develop an integrated MSI-platform capable of achieving high mass- and spatial-resolution, as well as discrimination of lipid isomers. Resolution of lipid isomers using this instrumentation will afford researchers a first glimpse of isomer-resolved images that will be used to visualise tissue-specific changes resulting from underlying chemical, physical or metabolic processes; changes that are currently invisible to contemporary imaging technologies.Read moreRead less
Pluses and minuses of lipid mass spectrometry. This project aims to investigate the structural diversity of lipids. Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of cer ....Pluses and minuses of lipid mass spectrometry. This project aims to investigate the structural diversity of lipids. Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of certain lipids to ionise with a polarity that affords sensitive detection but does not permit detailed structure elucidation. This project will develop advanced instrumentation capable of on-demand polarity switching of ionised lipids such that the detection and interrogation of molecular structure can take place in the optimal charge state.Read moreRead less
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
