Genetic regulation of testis development in the chicken embryo. This project aims to shed light on the genetic control of testis development during embryonic life, using the chicken embryo as a model. The results will have implications for sex ratio manipulation in poultry and for our understanding of sexual disorders in humans.
Genetic regulation of wing reduction in the emu. This project aims to examine the genetic mechanisms that generate limb diversity, using wing reduction in the emu as a model. A hot topic in biology at present is evolutionary developmental biology, or how genes control morphological diversity. This project will explore the functions of two novel genes implicated in wing reduction. The project expects to expand knowledge in the area of developmental biology, and limb morphogenesis specifically. It ....Genetic regulation of wing reduction in the emu. This project aims to examine the genetic mechanisms that generate limb diversity, using wing reduction in the emu as a model. A hot topic in biology at present is evolutionary developmental biology, or how genes control morphological diversity. This project will explore the functions of two novel genes implicated in wing reduction. The project expects to expand knowledge in the area of developmental biology, and limb morphogenesis specifically. It will bear upon the phylogeny of flightlessness among birds. It also has potential implications for studying human limb deformities. Overall, the project will enhance our understanding of how genes control the great diversity that we see in nature.Read moreRead less
Specification of the nerve cell subtypes in the developing central nervous system. Different subtypes of nerve cells in the brain, which carry out distinct functions, are generated in the embryo by the co-ordinated action of many genes. This project aims to use the genetic advantages of the zebrafish to determine the role of genes in specifying the final fates of nerve cells in the retina, which analyses visual signals within the eye.
Defining a role for non-coding RNAs in gonadal sex differentiation. This project aims to increase knowledge in the area of developmental biology, studying how gene regulation by so-called non-coding RNAs contributes to tissue patterning. The project plans to use a unique model system: gonadal development in the chicken embryo. It also plans to use novel molecular approaches that exploit the chicken model to study the role of microRNAs and a long non-coding RNA in patterning the embryonic gonad. ....Defining a role for non-coding RNAs in gonadal sex differentiation. This project aims to increase knowledge in the area of developmental biology, studying how gene regulation by so-called non-coding RNAs contributes to tissue patterning. The project plans to use a unique model system: gonadal development in the chicken embryo. It also plans to use novel molecular approaches that exploit the chicken model to study the role of microRNAs and a long non-coding RNA in patterning the embryonic gonad. The project aims to provide a deeper understanding of how genes operate to control tissue patterning and organogenesis. It may thus inform the field of sex determination specifically, and, more broadly, stem cell biology and tissue engineering.Read moreRead less
Morphological development of the kidney – a paradigm for organogenesis. This project aims to shed new light on how the kidney develops, how normal adult function is established and how congenital kidney malformations occur. It aims to investigate a mathematical pattern that has been discovered in the program of branching morphogenesis which dictates kidney development. By combining cutting-edge genetic approaches, morphological analysis and mathematical modelling, this project plans to explore h ....Morphological development of the kidney – a paradigm for organogenesis. This project aims to shed new light on how the kidney develops, how normal adult function is established and how congenital kidney malformations occur. It aims to investigate a mathematical pattern that has been discovered in the program of branching morphogenesis which dictates kidney development. By combining cutting-edge genetic approaches, morphological analysis and mathematical modelling, this project plans to explore how this pattern is established, how it dictates kidney development and whether it constitutes an ancient mechanism central to organ formation. Project outcomes may improve understanding of fundamental developmental processes and developmental disease and variation. Project findings may also be important for understanding the development of other organ systems.Read moreRead less
The neurocognitive basis of dual-task co-ordination impairment in Alzheimer’s: defective coordination mechanism or differences in speed of processing? This project explores the effects of age, depression and Alzheimer’s disease on the ability to carry out two tasks at once, to determine whether difficulty doing so is due to slowed mental processing, or to a deficit in a mechanism responsible for task coordination. The project will advance cognitive theory and may help with diagnosis of dementia.
Novel mechanisms integrating the central and autonomic nervous system. This project aims to define molecular mechanisms controlling the exquisite connectivity of neurons in different parts of the body. The ability of higher-vertebrates to respond to different environmental conditions is essential for life, evolution, health, reproduction and growth, and is reliant on the autonomic nervous system. However, how the autonomic nervous system is integrated with the central nervous system to control h ....Novel mechanisms integrating the central and autonomic nervous system. This project aims to define molecular mechanisms controlling the exquisite connectivity of neurons in different parts of the body. The ability of higher-vertebrates to respond to different environmental conditions is essential for life, evolution, health, reproduction and growth, and is reliant on the autonomic nervous system. However, how the autonomic nervous system is integrated with the central nervous system to control holistic physiological responses is largely unknown. By deciphering how neural networks are formed this project aims to provide broad biological insight to wiring of the entire nervous system which is likely to have significant implications for the formation of synthetic neural networks and for regeneration.Read moreRead less
Atypical cognition in autism: preference for nonverbal coding and impaired connectivity? This project will investigate whether individuals with autism prefer to think 'in pictures' rather than use words, and whether their thinking shows evidence of limited connections across brain regions. Establishing either characteristic for autism would provide important direction in improving diagnosis and intervention for affected children.
Glucose facilitation of cognitive function: Effects of effort, age and glucose control. Age-related decline in mental capacity contributes to the economic (estimated at over 2 trillion AUD by 2050), social and human costs of an increasingly older Australian population. The studies in this program aim to understand the role of poor control of blood glucose in age-related cognitive deficits. The role of individual differences in biological (hormonal responses) and psychological (stress and appetit ....Glucose facilitation of cognitive function: Effects of effort, age and glucose control. Age-related decline in mental capacity contributes to the economic (estimated at over 2 trillion AUD by 2050), social and human costs of an increasingly older Australian population. The studies in this program aim to understand the role of poor control of blood glucose in age-related cognitive deficits. The role of individual differences in biological (hormonal responses) and psychological (stress and appetite) factors will also be assessed. A better understanding of the nature of age-related cognitive decline as it relates to biological processes such as blood glucose control will help to develop tangible strategies to combat age-related cognitive decline and dementia (which has been described as Type 3 diabetes).Read moreRead less
The molecular control of lymphatic vascular differentiation. This project aims to improve our understanding of how a new vascular system forms and the molecules that control this process. Lymphatic vasculature plays roles in fluid drainage, inflammation, obesity, metastasis and tissue repair, yet we cannot readily promote or inhibit lymphatic vessel formation. This project aims to build new knowledge that is expected to improve our ability to generate lymphatic vessels for stem cell application ....The molecular control of lymphatic vascular differentiation.
