Summary
Three-dimensional super-resolution nanophotonic fabrication facility. This stimulated emission depletion microscopy nanophotonic fabrication facility will be the first nanophotonic fabrication facility that is able to achieve optical resolution far beyond the diffraction limit, which will facilitate breakthroughs in cutting-edge nanotechnology research areas.
Structurally designed catalysts for high-performance natural gas reforming. This project aims to develop a new class of highly stable catalysts with specially designed physical and chemical structures that can be used in high temperature chemical processes. These catalysts can potentially be used for the reforming of natural gas to produce the synthesis gas, which can then be used to produce liquid fuels and chemicals.

Summary
Platelets are the richest source of amyloid precursor protein (APP) in the body. Platelet ADAM10 regulates both the expression and function of the major platelet collagen receptor GPVI, and protective APP processing. Coagulation protein Factor X has a role in activation of ADAM10. This activation is disrupted in blood that has been treated with direct oral anticoagulant (DOAC) rivaroxaban. This grant will investigate the implications for people taking rivaroxaban on regulation of APP and GPVI.

Summary
The Presenilin and APP proteins are centrally important in inherited, early onset Alzheimer's disease. We have discovered that a shortened form of Presenilin protein, "PS2V", appears to increase specifically the rate at which the APP protein is cleaved to produce the "Amyloid beta" protein fragment that is found in Alzheimer's disease brains. This occurs when brain cells are under oxidative stress.

Summary
Currently, about 160,000 Australians suffer from dementia; of which 50-70% are Alzheimer's disease (AD) cases. AD is characterised clinically by memory and personality changes and pathologically by deposition of amyloid. Of particular importance in the disease pathogenesis, is a small molecule called beta amyloid, of which the overproduction is thought to be central to the development of AD.

AD is characterised clinically by memory and personality changes and pathologically by deposition of amyloid. Of particular importance in the disease pathogenesis, is a small molecule called beta amyloid, of which the overproduction is thought to be central to the development of AD. Changes in the levels of the reproductive hormones, particularly low levels of oestrogen during menopause or testosterone during andropuase, has been associated with the increased risk of developing AD and in altering the levels of beta amyloid. Furthermore, menopause and andropause are also characterised by changes in other reproductive hormones such as the gonadotropins. High levels of the gonadotropins have also been associated with the increased risk of developing AD. Therefore it is important to identify how these changes modify the risk of developing AD. This study examines the role of the gonadotropins in regulating beta amyloid levels in cell culture and in an animal model for AD. Furthermore, this study will assess, in the animal model, the use of gonadotropin lowering agents to reduce levels of beta amyloid. The results from this study will provide important data on how reproductive hormones regulate beta amyloid. Further insight into these mechanisms will provide therapeutic or preventative strategies for AD.Read moreRead less

The goal of this project is to develop innovative colloidal nanocrystal heterostructures to provide the basis for eco-friendly optoelectronic devices and photocatalysis as well as other advanced applications. One-dimensional semiconductor nanocrystals have desirable electronic and catalytic properties (a linearly polarised emission, large absorption cross section, reduced lasing threshold and improved charge separation and transport). However, present investigations of these materials are mainly limited to highly toxic cadmium chalcogenides. This project aims to explore a family of cadmium-free colloidal nanocrystal heterostructures with the desired properties. The project intends to investigate their growth mechanisms, properties and effects to support product development and advance the fundamental knowledge of electronics at the nanoscale.Read moreRead less

One of the common biochemical characteristics of cancer-leukaemia cells is augmented activity levels of enzymes called tyrosine kinases. A major group of tyrosine kinase involved in several cancer-leukaemia types is called the Src family of tyrosine kinases. One member of this family called Lyn has been our focus of study for several years, investigating the signalling pathways that it is involved in. This molecule has also been implicated in several specific leukaemia (Chronic Myeloid Leukaemia and Acute Myeloid Leukaemia) as well as cancer (Prostate, Colon, Breast) in recent years. We have identified a novel mechanism of down-regulation of this enzyme mediated by an adapter molecule called Cbp, which recruits the Lyn inactivating molecules Csk-Ctk as well as SOCS-1; together they inhibit the activity of Lyn and degrade the enzyme. Using our knowledge of the essential interaction elements of Cbp we will design and test various mini-Cbp molecules for their ability to inactivate and degrade Lyn in leukemic and cancer cells. These molecules may allow us to develop novel therapeutics capable of inactivating-degrading specific tyrosine kinases in cancer and leukaemia.Read moreRead less

The production of red blood cells is primarily controlled by the hormone erythropoietin (epo). The availability of this hormone in a recombinant form has aided in the treatment of numerous forms of anaemia resulting from kidney failure, malignancies, and AIDS. Previously we had identified that the protein Lyn must be present inside primitive red blood cells for epo to stimulate them to become mature functional cells. We have identified six molecules which interact with Lyn in red blood cells. We have shown that amolecule called HS1 is important for epo function in individual red blood cells and now we plan to investigate its functions in whole animals, including mice that lack the HS1 gene. We have also shown that a molecule called Trip1 is important for red blood cell development. Interestingly, this molecule also interacts with the thyroid hormone receptor and can influence the effects of epo and thyroid hormone on red blood cell development. The interplay between these two hormones will be looked at in more detail both at the cell and whole animal levels in normal mice and those lacking the thyroid hormone receptor gene. The third Lyn binding molecule we isolated is a novel gene-we have named it ankyrin repeat protein in line with the molecules it is related to. This gene is expressed in red blood cells and we aim to investigate what role it plays in the development of these cells. The fourth gene is also novel and is closely related to another called AFAP-110, which can exert effects on the structure of a cell. Its role in red blood cell structure will also be investigated. Finally, the last two molecule we have identified are both novel and are unrelated to any other known proteins. As above, the effects of these two molecules on red blood cell development will be investigated.Read moreRead less
