Summary
Pushing the limits of fluorescence microscopy with adaptive optics. This project aims to establish an adaptive optics, super-resolution optical microscopy facility to image cellular events with the highest possible spatial resolution, in a whole cell or tissue context. Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples. This adaptive optics system ....Pushing the limits of fluorescence microscopy with adaptive optics. This project aims to establish an adaptive optics, super-resolution optical microscopy facility to image cellular events with the highest possible spatial resolution, in a whole cell or tissue context. Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples. This adaptive optics system will enable researchers to study complex behaviour of biological specimens, at the optical resolution limit in plant and animal tissues, leading to basic biology and biotechnology outcomes in biofuels, biomaterials and biomedicines.Read moreRead less

Dual column focused ion beam/scanning electron microscope facility: This facility will precisely cut specimens and surfaces that can be imaged in a variety of ways, including crystallographic and elemental space, of particular use for physical scientists, as well as biological specimens. This instrument will provide information at resolutions between optical and transmission electron microscopy, images that will effectively provide the biologist with the ability to develop the complete correlative picture of organelles and cells. The instrument will also provide a much needed resource for researchers across disciplines such as physics, chemistry, biology, geology and engineering.Read moreRead less
Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this ....Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this study will be a catalogue of functionally active circRNAs. Over the past decades, the wealth of knowledge on the function of linear mRNAs has had a significant impact on medicine and agriculture. Similarly understanding how circRNAs regulate cellular activities may have an analogous impact on humans.Read moreRead less
The structure of heteromeric amyloid fibrils with signaling activity. This project aims to determine the composition, structure and properties of important protein complexes involved in a newly identified cell death pathway known as necroptosis. This cell death pathway removes unwanted or damaged cells during development or infection. These necroptosis protein complexes are unusual because they have a fibrillar amyloid structure, contain more than one protein type in the fibrils and have a funct ....The structure of heteromeric amyloid fibrils with signaling activity. This project aims to determine the composition, structure and properties of important protein complexes involved in a newly identified cell death pathway known as necroptosis. This cell death pathway removes unwanted or damaged cells during development or infection. These necroptosis protein complexes are unusual because they have a fibrillar amyloid structure, contain more than one protein type in the fibrils and have a functional, signalling role. The research will determine how these fibrils form and how the structures confers biological function. It could identify features in these fibrils that can be targeted as a means of ultimately preventing tissue damage after heart attack and stroke.Read moreRead less
The genetic regulation of organogenesis: endoderm development in the Drosophila embryo. Embryonic development is an important research field in biology, not only for its extraordinary complexity but also because of the insights it provides into molecular processes that underpin a variety of diseases. This project aims to discover genes and molecules that regulate the normal development of one of the most important organs, the gut.
How cell shape regulators control cell competition in tissue development. This project aims to determine how cell shape (polarity) regulators affect cell survival in an epithelial tissue. When mutation or wounding perturb cell shape regulators in a tissue cell, signalling pathways are altered that kill the aberrant cells. A surveillance mechanism termed "cell competition" is important to remove the damaged cells. This project will investigate a potential regulator of cell competition, the tyrosi ....How cell shape regulators control cell competition in tissue development.

When mutation or wounding perturb cell shape regulators in a tissue cell, signalling pathways are altered that kill the aberrant cells. A surveillance mechanism termed "cell competition" is important to remove the damaged cells. This project will investigate a potential regulator of cell competition, the tyrosine phosphatase PTP61F, in response to perturbation of cell shape regulators, using the vinegar fly, Drosophila, and mammalian systems. This study is expected to reveal biomarkers that can be used to improve organismal fitness to increase productivity or to decrease it for pest control.Read moreRead less
How the red blood cell loses its nucleus. This project aims to provide insights into erythroid enucleation, the process by which red blood cells extrude their nucleus so that they can circulate through the microvasculature. Although the enucleated character of mammalian red blood cells has been known for more than 150 years, the mechanism underlying this process is virtually unknown. This project will use a live imaging approach to characterise in vivo the cellular interactions and molecular pat ....How the red blood cell loses its nucleus.

Although the enucleated character of mammalian red blood cells has been known for more than 150 years, the mechanism underlying this process is virtually unknown. This project will use a live imaging approach to characterise in vivo the cellular interactions and molecular pathways required for enucleation. The project will provide a molecular and cellular road map of enucleation that may be utilised to enhance the bulk therapeutic in vitro production of red blood cells for veterinary and human purposes.Read moreRead less

Mass cytometry - a breakthrough in multidimensional systems biology: Mass Cytometry by Time of Flight marries the resolution, specificity and sensitivity of atomic stable isotope mass spectrometry to the high-throughput, single-cell analytical advantages of flow cytometry. Using molecular probes conjugated with stable isotope tags, a large increase is possible in the number of simultaneous quantitative measurements in complex samples. These parameters, denoting cell type, function and signalling status, will make possible future advances in the understanding of the diversity of cell phenotype and function with a systems biology approach.
