Defining targets and generating tools/therapeutic agents for prevention, diagnosis and therapy of atherothrombosis. Atherosclerosis and its complications such as myocardial infarction and stroke are a major cause of death and disability in Australia and worldwide. The proposed research program investigates new therapeutic targets and concepts (e.g. targeting of stem cells) to treat atherosclerosis and aims to develop new therapeutic agents using modern biotechnological methods. The project furth ....Defining targets and generating tools/therapeutic agents for prevention, diagnosis and therapy of atherothrombosis. Atherosclerosis and its complications such as myocardial infarction and stroke are a major cause of death and disability in Australia and worldwide. The proposed research program investigates new therapeutic targets and concepts (e.g. targeting of stem cells) to treat atherosclerosis and aims to develop new therapeutic agents using modern biotechnological methods. The project further aims to develop nanoparticle-based diagnostic tools to identify and preventatively treat atherosclerotic plaques that are prone to cause myocardial infarction. The expected outcome will provide direct benefit to patients and create new economic opportunities in Australian bio-/nanotechnology.Read moreRead less
Bioreactors for manufacture of human platelets. Blood cell transfusion is a critical part of medicine that is supported by volunteer donors. Unfortunately, the demand for blood cells for transfusion far outstrips supply and therefore new strategies are required for manufacture of blood cells. This project will lead to the development of technology for manufacture of human platelets from stem cells. The systems devised will be applicable to a broad range of other blood cell types.
Molecular signals that regulate the regenerative properties of intestinal epithelial cells. Most cancer deaths are due to the cancer spreading to other organs. Cancer is much more difficult to treat once it has spread to other organs in the body where the cancer cells can exist in a dormant state. Dormant cancer cells evade conventional anticancer treatment and can remain dormant for a very long time before they change back to a 'tumour-growing' state. An understanding of how the cancer initiati ....Molecular signals that regulate the regenerative properties of intestinal epithelial cells. Most cancer deaths are due to the cancer spreading to other organs. Cancer is much more difficult to treat once it has spread to other organs in the body where the cancer cells can exist in a dormant state. Dormant cancer cells evade conventional anticancer treatment and can remain dormant for a very long time before they change back to a 'tumour-growing' state. An understanding of how the cancer initiating (stem cell) property of tumour cells is maintained offers potential novel avenues to eliminate persistent cancer cells. This knowledge will ultimately lead to better management and treatment of cancer, and increase survival. An understanding of stem cell behaviour is also central to the control of degenerative conditions.Read moreRead less
Beyond Spectral Detection: Engineering SUPER Dot Probes for High-Throughput Discovery. Molecules that are altered as a result of a pathological condition are generally present in very low abundance, and pose a “needle-in-a-haystack” problem. Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. This project will develop a new generation of nanophotonic luminescent probes (Strong Upconversion Photo-stable Encoded ....Beyond Spectral Detection: Engineering SUPER Dot Probes for High-Throughput Discovery. Molecules that are altered as a result of a pathological condition are generally present in very low abundance, and pose a “needle-in-a-haystack” problem. Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. This project will develop a new generation of nanophotonic luminescent probes (Strong Upconversion Photo-stable Encoded nano-Radiators (SUPER) Dots), based on purpose-engineered up-conversion nanocrystals that are ultra-bright and have low background interference, high specificity, speed, and large-scale multiplexing capacity. These probes will allow microscopy and flow cytometry to measure hitherto undetectable rare-event molecules and cells, opening new frontiers for the discovery of new biomarkers.Read moreRead less
Microscale microRNA Detection and Delivery for Effective Point-of-Care Cancer Screening and Therapeutics. MicroRNAs are short RNA molecules that play a critical regulatory role in gene expression. Recently discovered in 1993, microRNA research has since received considerable attention and is regarded as an emerging revolutionary frontier in medicine given its therapeutic ability to ‘turn off’ certain genes that lead to various diseases. Additionally, microRNA expression signatures are a strong b ....Microscale microRNA Detection and Delivery for Effective Point-of-Care Cancer Screening and Therapeutics. MicroRNAs are short RNA molecules that play a critical regulatory role in gene expression. Recently discovered in 1993, microRNA research has since received considerable attention and is regarded as an emerging revolutionary frontier in medicine given its therapeutic ability to ‘turn off’ certain genes that lead to various diseases. Additionally, microRNA expression signatures are a strong biomarker for many diseases such as cancer. This project will advance the chip-scale acoustic microcentrifugation and nebulisation technology we recently pioneered to overcome the significant hurdles currently faced in microRNA detection and delivery with the aim of developing prototype portable microdevices for early stage cancer screening and therapy.Read moreRead less
