Novel kinases: How do they regulate epithelial ion transport, and what is their role in epithelial function? The project will produce the knowledge of fundamental physiology that will lead to novel approaches for treating respiratory and gastrointestinal infections and cystic fibrosis, as well as for the accumulation of fluid in the lungs and abdomen that accompany many advanced malignancies. It thus has the potential to have a significant economic and social impact in Australia and internation ....Novel kinases: How do they regulate epithelial ion transport, and what is their role in epithelial function? The project will produce the knowledge of fundamental physiology that will lead to novel approaches for treating respiratory and gastrointestinal infections and cystic fibrosis, as well as for the accumulation of fluid in the lungs and abdomen that accompany many advanced malignancies. It thus has the potential to have a significant economic and social impact in Australia and internationally. Furthermore, it will provide advanced training in research methods to Australian scientists, equipping them to undertake challenging and interesting positions in the medical and life sciences and beyond.Read moreRead less
A new paradigm for surfactant composition and function - how do lungs cope with stress? Our research will increase the understanding of the scope of change and precise molecular interactions occurring in the surfactant lipids and proteins of animals under physiological stress. The novel insights will improve the treatment of lung diseases (such as chronic obstructive pulmonary disease and acute lung injury). We have formed a team of international surfactant researchers all experts in state-of-th ....A new paradigm for surfactant composition and function - how do lungs cope with stress? Our research will increase the understanding of the scope of change and precise molecular interactions occurring in the surfactant lipids and proteins of animals under physiological stress. The novel insights will improve the treatment of lung diseases (such as chronic obstructive pulmonary disease and acute lung injury). We have formed a team of international surfactant researchers all experts in state-of-the-art chemical and biophysical technologies relating to surfactant. These collaborations will bring new technological applications to Australia and provide outstanding cross-disciplinary training for postgraduate students and research staff at the interface between animal physiology, biophysical chemistry and respiratory medicine.Read moreRead less
Environmental control of genetic/phenotypic interactions in lung development: An evolutionary perspective. Vertebrate lungs all contain morphologically and functionally similar lung lining cells. However, the cellular arrangement (i.e. lung morphology) and the function of the surfactant these cells produce, differs dramatically between species. Hence, a subset of highly conserved lung-specific genes coincides with spectacular phenotypic diversity. How has this diversity evolved? Do environmental ....Environmental control of genetic/phenotypic interactions in lung development: An evolutionary perspective. Vertebrate lungs all contain morphologically and functionally similar lung lining cells. However, the cellular arrangement (i.e. lung morphology) and the function of the surfactant these cells produce, differs dramatically between species. Hence, a subset of highly conserved lung-specific genes coincides with spectacular phenotypic diversity. How has this diversity evolved? Do environmental conditions, birth strategy or phylogenetic relationships determine lung phenotype? We will experimentally manipulate developing lungs and cells to demonstrate how environmental conditions (temperature, oxygen, lung-fluid regulation and neuro-hormonal input) promote evolutionary processes by altering gene expression, protein/lipid synthesis, cellular differentiation and hence lung morphology/function in animals with different birth strategies.Read moreRead less
Structural determination of respiratory membrane protein complexes by X-ray crystallography. Membrane proteins form only 0.3% of the available protein structures in the protein data bank (PDB), yet 30% of the proteins in the human genome and 50% of human drug targets are membrane proteins. We have managed to increase the success rate through rational screening and development of new crystallization screens, with downstream implications for basic and medical research. Results from this proposal w ....Structural determination of respiratory membrane protein complexes by X-ray crystallography. Membrane proteins form only 0.3% of the available protein structures in the protein data bank (PDB), yet 30% of the proteins in the human genome and 50% of human drug targets are membrane proteins. We have managed to increase the success rate through rational screening and development of new crystallization screens, with downstream implications for basic and medical research. Results from this proposal will receive international recognition and will encourage more research in this field, attracting international funding, and create new research opportunities.
