Dissecting the impact of stress on reproduction: Novel peptide mediates inhibitory effects of stress on female reproduction. This research proposal offers a pioneering opportunity to develop treatments that overcome the negative impact of stress on reproduction. Specifically, knowledge generated in this project will be vital in the development of strategic defences against the impact of stress on reproduction.

This research proposal offers a pioneering opportunity to develop treatments that overcome the negative impact of stress on reproduction. Specifically, knowledge generated in this project will be vital in the development of strategic defences against the impact of stress on reproduction. This project fundamentally addresses Research Priority 2: Promoting and maintaining good health. Given that suppression of reproduction by stress occurs in all mammalian species including humans, domestic animals and wildlife, being able to prevent or overcome stress-induced reproductive dysfunction will generate significant health, social, economic and ecological benefits.

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
Regenerating lizard tails: A model for understanding the process of lymphangiogenesis. In humans, impaired lymphatic drainage in limbs causes the debilitating swelling termed lymphoedema. Lymphoedema affects 500,000,000 people worldwide. In the developed world lymphoedema predominantly results from surgery for cancer, and occurs in approximately 25% of breast cancer patients. We will examine lymph vessel regeneration (lymphangiogenesis) in a naturally regenerating, complex structure (the lizard ....Regenerating lizard tails: A model for understanding the process of lymphangiogenesis. In humans, impaired lymphatic drainage in limbs causes the debilitating swelling termed lymphoedema. Lymphoedema affects 500,000,000 people worldwide. In the developed world lymphoedema predominantly results from surgery for cancer, and occurs in approximately 25% of breast cancer patients. We will examine lymph vessel regeneration (lymphangiogenesis) in a naturally regenerating, complex structure (the lizard tail), to describe the regrowth process and determine the abundance, location, functional properties and molecular control of the new lymphatics. Furthermore, if reptilian lymphatic growth factors can promote lymphangiogenesis in mammals, we can design novel therapeutic approaches using reptilian ligands to promote lymphangiogenesis in lymphoedematous human tissues.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

Summary
Biomedical Engineering Sensing and Imaging Facility. The sensing and imaging facility will be the only national facility for leading engineering and medical researchers to undertake multidiscipline research into live and model biological systems. The facility will capture and combine existing strengths in these fields in Melbourne. This will provide new insights into the physiology of human, animal and plant systems and the development of preventive and curative strategies for disease.
