Regulated muscle-based thermogenesis for body temperature regulation. Mammals maintain a constant core body temperature by generating heat in resting muscles in response to changes in the environmental temperatures. This project aims to show how the skeletal muscles that are closer to the body core contribute the majority of heat, how the muscles of the limbs have their heat generation curtailed as necessary, and how this is coordinated by the body in response to ambient temperature. Project out ....Regulated muscle-based thermogenesis for body temperature regulation. Mammals maintain a constant core body temperature by generating heat in resting muscles in response to changes in the environmental temperatures. This project aims to show how the skeletal muscles that are closer to the body core contribute the majority of heat, how the muscles of the limbs have their heat generation curtailed as necessary, and how this is coordinated by the body in response to ambient temperature. Project outcomes include defining, for the first time, how heat generation in the muscles of the body is regulated. This should provide critical knowledge of mammalian evolution and ways to manipulate metabolism, which may provide ways to assist the production of meat by managing hypothermia and hyperthermia risk in agriculture.Read moreRead less

Responding to industry calls for improved methods of detecting and managing infertility in both stallions and mares, this project aims to provide a platform for competitive collaborations between universities, biotechnology companies and horse breeders: the end-users of technological developments in equine reproduction. The Thoroughbred and Standardbred breeding industries contribute over $6.5 billion per annum to the Australian economy and employ thousands of staff across their value chains. However, these industries suffer from breeding program inefficiencies that amount to over $800 million in annual losses. Expected outcomes are novel reproductive technologies and specialised research capabilities that will make the Australian equine industry a global leader.Read moreRead less
The regulation of skeletal muscle mass. This project aims to delineate a pathway involved in regulating skeletal muscle mass, and examine whether disrupting mitochondrial phospholipid synthesis affects mitochondrial structure and function, causing muscle wasting. Defining a new atrophy pathway will advance understanding of the mechanisms that control muscle mass.

This project could have important economic and quality of life benefits, especially for agriculture, where achieving optimal muscle mass ensures international competitiveness, productivity and economic growth, and successful ageing, where maintaining muscle mass is essential.Read moreRead less
Molecular control of embryonic diapause. Many species can halt growth of the early embryo (diapause). This project will use novel animal models and new proteomics techniques to clarify what signals from the uterus control diapause of the embryo. This may uncover new mechanisms for cell regulation that will be relevant to the biology of stem cells, cancer and reproductive technologies.

Interrogating the adaptive potential of skeletal muscle. Disruptions to muscle oxidative capacity and growth signalling underpin atrophy and dysfunction with ageing, which impacts on an individual’s quality of life. These biological processes are thought to be mutually exclusive and compete during muscle adaptation. This project aims to define how these processes regulate the extent of muscle adaptation, and how modifying these attributes influence functional capacity in the context of ageing.

Disruptions to muscle oxidative capacity and growth signalling underpin atrophy and dysfunction with ageing, which impacts on an individual’s quality of life. These biological processes are thought to be mutually exclusive and compete during muscle adaptation. This project aims to define how these processes regulate the extent of muscle adaptation, and how modifying these attributes influence functional capacity in the context of ageing. This project will provide fundamental new knowledge in understanding how modifying muscle attributes influence successful ageing. This knowledge will improve resilience, productivity, and wellbeing of all Australians, with implications for reducing societal and economic burden.Read moreRead less

They are used extensively for food, antibiotic and chemical production and, increasingly, for generating cheap substrates for bioethanol. However many are serious pathogens of plants and humans. Understanding how fungi control their metabolism is of fundamental importance for their more effective use or control. This project takes advantage of a fungus that is easily studied in the laboratory by advanced genetic techniques to identify the ways in which genes are turned on and off in response to changes in the nutrients available. By comparing DNA sequences the results are readily applied to fungi of economic importance.Read moreRead less
Age-related mechanisms of amino acid signalling in skeletal muscle. This project aims to increase our understanding of the role of glycine receptor-mediated signalling and its metabolism in the amino acid sensing capacity of mTORC1, a key enzyme regulating muscle protein synthesis. Ageing is associated with a progressive decline in skeletal muscle mass, weakness, and impaired regeneration after injury. Impaired anabolic signalling after food intake has been proposed as a key contributor, yet the ....Age-related mechanisms of amino acid signalling in skeletal muscle. This project aims to increase our understanding of the role of glycine receptor-mediated signalling and its metabolism in the amino acid sensing capacity of mTORC1, a key enzyme regulating muscle protein synthesis. Ageing is associated with a progressive decline in skeletal muscle mass, weakness, and impaired regeneration after injury. Impaired anabolic signalling after food intake has been proposed as a key contributor, yet the metabolic pathways responsible for nutrient sensing and regulation of protein synthesis remain unresolved. The project will assess defective amino acid sensing and protein synthesis in old mammals, identifying the role of glycine signalling in these processes. The project expects to underpin development of muscle-specific modulators of muscle homeostasis with broad relevance to Australia’s ageing population.Read moreRead less
Role of suppressor of cytokine signalling proteins (SOCS3) in defective muscle repair and ageing. Old muscles are slower and weaker than young muscles, they are injured more easily and they repair less successfully. This proposal investigates the role of SOCS3-signalling in muscle repair, ultimately to improve healing and to promote healthy ageing that will enable older Australians to enjoy a better quality of life.
