Aquaporin channels in cell migration. The project aims to determine the role of Aquaporin1 (AQP1) in enhancing rapid cell motility. Cell migration is important for development, repair, and protection in multicellular organisms. AQP1 is increased in some rapidly migrating cell types. Loss of AQP1 impairs migration, which is restored by reintroduction of AQP1 but not AQP4. Expected outcomes include defining the features of AQP1 that confer enhanced cell migration. The project will test the hypothe ....Aquaporin channels in cell migration. The project aims to determine the role of Aquaporin1 (AQP1) in enhancing rapid cell motility. Cell migration is important for development, repair, and protection in multicellular organisms. AQP1 is increased in some rapidly migrating cell types. Loss of AQP1 impairs migration, which is restored by reintroduction of AQP1 but not AQP4. Expected outcomes include defining the features of AQP1 that confer enhanced cell migration. The project will test the hypothesis that dual water and ion channel functions of AQP1 are needed for movement, using migration assays in cells with wild type and mutant AQP1, and selective pharmacological agents developed by the project team to dissect the essential channel properties that enable rapid migration in cancer and stem cells. The project seeks to build knowledge of AQP roles in development, regeneration and surveillance, potentially improving health care by revealing pathways in migration disorders such as metastasis.Read moreRead less
Fundamental roles of aquaporin-1 channels in cell migration and morphology. This project aims to investigate cell migration mechanisms and the roles of aquaporin channels in controlling cell motility and morphology. The ability of cells to move and maintain proper shape is important for development, repair and survival in multicellular organisms.

This project aims to investigate cell migration mechanisms and the roles of aquaporin channels in controlling cell motility and morphology. The ability of cells to move and maintain proper shape is important for development, repair and survival in multicellular organisms. This project will test the role of mammalian aquaporin-1 channels in enabling rapid migration in normal and cancer cells, in repairing barrier layers in kidney and brain, and in allowing red blood cells to maintain the classic disk-shape needed for optimal transport. Outcomes will define features of aquaporin-1 that provide these functions, using molecular, optical and pharmacological tools. Results will define aquaporin channel properties that enable optimal cellular function.Read moreRead less
Cardiac a1-adrenergic receptors in survival of the fittest. This project aims to determine the role of alpha1A-adrenergic receptor inactivation, a receptor/signalling pathway, in mediating cardiac contraction and survival in response to stressors fight-or-flight response triggers.Higher organisms’ ability to respond to environmental changes is central to the survival of the fittest, and is mediated by the release of catecholamines that stimulate adrenergic receptors. The precise receptor and sig ....Cardiac a1-adrenergic receptors in survival of the fittest. This project aims to determine the role of alpha1A-adrenergic receptor inactivation, a receptor/signalling pathway, in mediating cardiac contraction and survival in response to stressors fight-or-flight response triggers.Higher organisms’ ability to respond to environmental changes is central to the survival of the fittest, and is mediated by the release of catecholamines that stimulate adrenergic receptors. The precise receptor and signalling pathways underlying these adaptive responses remain unclear. This project’s research could improve contractility, reduce cardiomyocyte death and define organismal adaptation to extreme environmental changes.Read moreRead less
Nutritional and bacterial influences on gut and peripheral homeostasis. Nutritional and bacterial influences on gut and peripheral homeostasis. This project aims to understand the role of macronutrients on gut homeostasis. While the understanding of what factors affect gut homeostasis is still in its infancy, scientists know that its disruption contributes to a broad range of inflammatory diseases, including type 1 diabetes and asthma. This project will determine the role of specific macronutrie ....Nutritional and bacterial influences on gut and peripheral homeostasis. Nutritional and bacterial influences on gut and peripheral homeostasis. This project aims to understand the role of macronutrients on gut homeostasis. While the understanding of what factors affect gut homeostasis is still in its infancy, scientists know that its disruption contributes to a broad range of inflammatory diseases, including type 1 diabetes and asthma. This project will determine the role of specific macronutrients on gut microbiota, gut epithelium, and immunity in mice, and the receptors involved. This research could ultimately lead to significant decreases in the cost of healthcare.Read moreRead less

This project aims to establish a Lattice Light-Sheet Microscope (LLSM) Facility, to provide the dedicated computing infrastructure needed for terabyte-scale image acquisition and handling. Lattice light sheet microscopy allows four-dimensional imaging of live biological specimens from individual molecules to small organisms. The microscope images live specimens without phototoxicity or photobleaching, enabling prolonged imaging of significant physiological or biophysical events. Expected outcomes include high impact discoveries and publications in fundamental research, rapid solutions for industry-focussed projects and opportunities for collaboration, research and development. The imaging is expected to reveal key scientific insights and showcase biology to the public.Read moreRead less
Decoding the rules of fate, attraction and cell migration in perciform fish. This project will interrogate primordial germ cell migration to reveal new insights into the molecular basis of cell migration and chemosensory communication. Key residues needed for ligand-receptor binding and environmental impacts on migration will be investigated with valuable implications in reproductive developmental biology and applied science.
