Improved insect pest control through understanding mechanisms of insecticide action. Receptors in the nervous system relay signals required for nerve function. Insecticides targeting these receptors provide insect pest control. Better insecticides could be designed if the proteins involved in receptor assembly function were known. In identifying these proteins this project will improve options for safe and effective pest control.
Development of the PD GeneChip: a research and diagnostic tool for Parkinson's disease. The PD GeneChip will provide both social and economic benefits to Australia. It will be a key research platform for Australian scientists, and will facilitate collaboration both within Australia and overseas. It will assist with health care management of PD (Parkinson's disease) patients by providing a cost-effective diagnostic tool and the possibility of predicting the clinical course of disease. This inform ....Development of the PD GeneChip: a research and diagnostic tool for Parkinson's disease. The PD GeneChip will provide both social and economic benefits to Australia. It will be a key research platform for Australian scientists, and will facilitate collaboration both within Australia and overseas. It will assist with health care management of PD (Parkinson's disease) patients by providing a cost-effective diagnostic tool and the possibility of predicting the clinical course of disease. This information will provide the basis for tailoring treatment to a patients needs. It is anticipated that marketing of the PD GeneChip within Australia and overseas may produce revenue of at least $40 million annually.Read moreRead less
Single minded 1 in neuron development and satiety signalling. An understanding of how Single minded 1 (SIM1) regulates target genes may allow new pharmaceutical approaches to be designed to combat obesity. As Sim1 belongs to a family of closely related gene regulatory proteins which function in early development and homeostasis, deciphering the molecular control mechanisms of Sim1 may help understand how the related factors function in processes such as angiogenesis, response to low oxygen stres ....Single minded 1 in neuron development and satiety signalling. An understanding of how Single minded 1 (SIM1) regulates target genes may allow new pharmaceutical approaches to be designed to combat obesity. As Sim1 belongs to a family of closely related gene regulatory proteins which function in early development and homeostasis, deciphering the molecular control mechanisms of Sim1 may help understand how the related factors function in processes such as angiogenesis, response to low oxygen stress, invasion of environmental pollutants and autism spectrum diseases. The ability to manipulate these factors would be of great benefit in treating a range of disorders, but a thorough molecular understanding of these factors needs be obtained prior to attempting design of pharmaceuticals.Read moreRead less
Imaging genetics in schizophrenia and bipolar disorder: shared neurocognitive endophenotypes. Combined, schizophrenia and bipolar disorder afflict approximately 506,000 Australians at any one time, and are leading causes of disability and national economic burden. This study will delineate genetic underpinnings for these conditions in association with specific neurocognitive dysfunctions that are common to both disorders. These findings have important implications for the implementation of perso ....Imaging genetics in schizophrenia and bipolar disorder: shared neurocognitive endophenotypes. Combined, schizophrenia and bipolar disorder afflict approximately 506,000 Australians at any one time, and are leading causes of disability and national economic burden. This study will delineate genetic underpinnings for these conditions in association with specific neurocognitive dysfunctions that are common to both disorders. These findings have important implications for the implementation of personalised pharmaceutical treatments on the basis of genotype, and the development of therapeutic agents to target cognitive function. These results will also aid detection of premorbid psychotic illness in young individuals who may benefit from early intervention that may thwart the illness trajectory. Read moreRead less
Elucidating the neural pathways and genetic basis of speech. The project will elucidate the biological basis of speech, a unique feature of the human condition. The project will do this by i) discovering genes associated with speech disorder and ii) defining the neural pathways associated with speech production. This study will address critical questions regarding gene, brain and behaviour relationships in speech.
Truncating presenilin mutations and their effects on gamma-secretase activity, tau and beta-catenin - insights into Alzheimers disease and cancer. Cancer and dementia are primarily afflictions of the aged and are increasingly important in an aging Australian population. 95% of all Alzheimer's disease is spontaneous (not inherited) but we know little about the molecular mechanisms underlying it. Our discovery that truncated presenilin proteins potently inhibit normal protein function suggests tha ....Truncating presenilin mutations and their effects on gamma-secretase activity, tau and beta-catenin - insights into Alzheimers disease and cancer. Cancer and dementia are primarily afflictions of the aged and are increasingly important in an aging Australian population. 95% of all Alzheimer's disease is spontaneous (not inherited) but we know little about the molecular mechanisms underlying it. Our discovery that truncated presenilin proteins potently inhibit normal protein function suggests that changes in presenilin function in aged cells might be a common molecular link between spontaneous and inherited Alzheimer's disease and could contribute to frontotemporal dementia and cancer. Our research will show whether this phenomenon might provide a breakthrough in our understanding of these diseases and be a productive area for research into their amelioration and/or prevention.Read moreRead less
Developing methods for the analysis of massively parallel sequencing data in family studies. This project will develop analytical methods to use the latest, high-throughput method of generating sequencing data, i.e. the letters of the human genome alphabet. These tools will be used to identify the causal mutations in families with inherited disorders, leading to diagnostic tests for these families.
Understanding the molecular mechanisms of intellectual disability. Intellectual disability is frequent in the population, with one in every fifty people in the world directly affected. This project will improve our understanding of the correct development and function of the brain required for cognition by investigating specific roles and regulation of key molecules involved.
Molecular dissection of the functional regions of genes that encode actinins (ACTN2 and ACTN3) and their contribution to normal variation in skeletal muscle function. The project has discovered a common genetic variant that affects skeletal muscle structure, function and metabolism and influences athletic ability, and response to diet and exercise. The project will study how this gene influences muscle bulk and strength, the metabolic efficiency of muscle and the risk of obesity in the general ....Molecular dissection of the functional regions of genes that encode actinins (ACTN2 and ACTN3) and their contribution to normal variation in skeletal muscle function.

Investigating insect neuronal plasticity under genetic and chemical stress. This project aims to study receptors that translate chemical signals into electrical signals in animal brains. These receptors are targeted by insecticides used to control the major pests that afflict agriculture and domestic pets. The project aims to establish the functions of nicotinic acetylcholine receptors in several behaviours and in insecticide responsiveness in the model insect, Drosophila melanogaster, using mut ....Investigating insect neuronal plasticity under genetic and chemical stress. This project aims to study receptors that translate chemical signals into electrical signals in animal brains. These receptors are targeted by insecticides used to control the major pests that afflict agriculture and domestic pets. The project aims to establish the functions of nicotinic acetylcholine receptors in several behaviours and in insecticide responsiveness in the model insect, Drosophila melanogaster, using mutations that knock out the function of receptor subunits. Prior research has pointed to plasticity in the expression and transport of these receptors in response to genetic and environmental change. This project aims to identify the underlying mechanisms that provide the insect with resilience, to provide better options for pest control.Read moreRead less
