Biochemistry of tropoelastin and elastin. Elastin is the main protein responsible for the elasticity of vertebrate tissues. The Weiss Lab makes large quantities of full-length tropoelastin, which is crosslinked to make elastin. We want to examine the biochemistry of tropoelastin, learn how its domains participate in elastin structure and assembly, and explore cellular responses to our synthetic elastin biomaterial. Remarkably little is known of this biochemistry because elastin is a highly cross ....Biochemistry of tropoelastin and elastin. Elastin is the main protein responsible for the elasticity of vertebrate tissues. The Weiss Lab makes large quantities of full-length tropoelastin, which is crosslinked to make elastin. We want to examine the biochemistry of tropoelastin, learn how its domains participate in elastin structure and assembly, and explore cellular responses to our synthetic elastin biomaterial. Remarkably little is known of this biochemistry because elastin is a highly cross-linked and substantially insoluble macroscopic network of tropoelastin multimers. Our availability of tropoelastin and synthetic elastin now makes these studies possible.Read moreRead less
Biomedical Applications of Self-Mixing Sensors based on Vertical-Cavity Surface-Emitting Laser Arrays. The Vertical-Cavity Surface-Emitting Laser (VCSEL) is a new optical device of choice for high speed optical data networks. We propose that this communications technology can be used as a platform to develop a completely new family of sensors ideally suited to medical monitoring. Specifically, we will develop VCSEL based technology for measurement of heart activity and sensing of blood flow in ....Biomedical Applications of Self-Mixing Sensors based on Vertical-Cavity Surface-Emitting Laser Arrays.

We propose that this communications technology can be used as a platform to develop a completely new family of sensors ideally suited to medical monitoring. Specifically, we will develop VCSEL based technology for measurement of heart activity and sensing of blood flow in skin and tissues. This will provide novel sensors for heart monitoring and imaging, and management of skin disorders (burns and cancer).Read moreRead less
Biochemistry of tropoelastin and elastin: the molecular architecture of elastic fibre assembly. Elastin destruction drives the progression of emphysema, a major component of chronic obstructive pulmonary disease which is a major cause of death. Loss of elastin leads to profound blockage of arteries. If we are to treat these problems we need to know how to make and repair elastin. This research will enable us to discover how elastin is constructed and define its interacting partners. We will lear ....Biochemistry of tropoelastin and elastin: the molecular architecture of elastic fibre assembly. Elastin destruction drives the progression of emphysema, a major component of chronic obstructive pulmonary disease which is a major cause of death. Loss of elastin leads to profound blockage of arteries. If we are to treat these problems we need to know how to make and repair elastin. This research will enable us to discover how elastin is constructed and define its interacting partners. We will learn how to make tissue components found in parts of the body that expand and contract such as the arteries, lung and skin. We will learn about the molecular mechanisms of elastin assembly and cell interactions, which gives us the core molecular toolkit to repair elastin tissue.Read moreRead less
Prediction of tissue fate and functional outcome in acute ischemic stroke with advanced imaging analysis - experimental validation and translational studies. Stroke is predominantly a disease of ageing and the commonest cause of adult disability. In Australia, 55,000 people have a stroke each year (>80% are over age 65). The total number of strokes per year worldwide will rise 60% within the next two decades as the proportion of elderly in our population increases. This research will improve bra ....Prediction of tissue fate and functional outcome in acute ischemic stroke with advanced imaging analysis - experimental validation and translational studies. Stroke is predominantly a disease of ageing and the commonest cause of adult disability. In Australia, 55,000 people have a stroke each year (>80% are over age 65). The total number of strokes per year worldwide will rise 60% within the next two decades as the proportion of elderly in our population increases. This research will improve brain imaging selection for acute stroke therapies in clinical trials and practice. Better acute stroke therapies limit the size of brain damage from stroke and reduce long-term disability. Thus, this research will directly translate into allowing our population to 'age well and productively'.Read moreRead less
The function of menin in mammalian development. This project aims to determine the role of a ubiquitous transcriptional co-regulator, menin, in mammalian development. Mice that lack menin through targeted deletion of the gene die during embryogenesis, but the cause is unknown, although is likely to be due to the abnormal expression of genes usually regulated by this factor. We will determine which genes are inappropriately expressed and responsible for the accompanying developmental defects. Thi ....The function of menin in mammalian development.

Targeting genes elevated in the athlete's heart to improve function of the failing heart. Cardiovascular disease affects about 3.7 million Australians and heart failure ranks as one of the major killers, representing a huge burden on our health care system and economy. This situation is likely to get worse with an increasing ageing population. Current therapeutics for heart failure patients largely delay disease progression but generally fail in significantly improving heart function and quality ....Targeting genes elevated in the athlete's heart to improve function of the failing heart. Cardiovascular disease affects about 3.7 million Australians and heart failure ranks as one of the major killers, representing a huge burden on our health care system and economy. This situation is likely to get worse with an increasing ageing population. Current therapeutics for heart failure patients largely delay disease progression but generally fail in significantly improving heart function and quality of life. The proposal has focused on targeting the protective effects of 'good' heart growth by identifying genes elevated in the heart in response to exercise. Targeting genes elevated in the athlete's heart to improve function of the failing heart represents a new strategy for the treatment of heart failure.Read moreRead less

The ApoE Interactome in Human Plasma. In this, the post-genome era, the emphasis has switched from the delineation of genome structure to the tremendous task of characterizing the gene products. One of the important aspects evolving in this new era is the design of strategies that enable identification of global protein-protein interactions, defined by the Human Proteome Organisation as the interactome. This, the apoE interactome in human plasma project, will identify novel interactions between ....The ApoE Interactome in Human Plasma. In this, the post-genome era, the emphasis has switched from the delineation of genome structure to the tremendous task of characterizing the gene products. One of the important aspects evolving in this new era is the design of strategies that enable identification of global protein-protein interactions, defined by the Human Proteome Organisation as the interactome. This, the apoE interactome in human plasma project, will identify novel interactions between plasma proteins and apoE, which is a lipid-binding protein genetically linked to age-related diseases affecting more than 500,000 Australians. This project will therefore provide scope for novel treatments and early detection of disease, namely cardiovascular and Alzheimer's disease.Read moreRead less
New functions for bioactive flavonoids in plants and mammals. We have discovered natural products with biological activity in plants and mammals.

We have discovered natural products with biological activity in plants and mammals. These molecules affect plant shape and development and the process of mammalian blood vessel formation. We seek to understand how these molecules work. More understanding is required before one can begin to utilise these molecules for possible beneficial agriculture or human health outcomes. Plant shape influences such things as yield or more drought-resilient root systems. Importantly, we have discovered specific molecules that either promote or inhibit blood vessel formation. A better understanding of how these molecules work could lead to novel treatments for cancer or cardiovascular disease.Read moreRead less
