Summary
Male sex hormone or androgen deficiency (AD) is a common, but under-diagnosed condition. AD decreases well being and contributes to muscle weakness, bone fragility and weight gain. Cutting edge technology will be used to help explain how AD may relate to these negative effects, particularly on muscle function. Given the importance of aging, frailty, osteoporosis and obesity, understanding the role of hormones in these conditions may have major implications for prevention and treatment.
Role Of UBL-5 In Mitochondrial Function And Glucose Metabolism

Summary
Type 2 diabetes is caused by insulin resistance, a condition that is characterised by the inability of insulin to elicit its normal function to lower blood sugar levels. The cause of insulin resistance is not known. In this study we will determine the role of a novel gene called UBL-5 to elicit insulin resistance in muscle and fat by generating genetically-induced models in which this gene has been deleted. By understanding the role of UBL-5 in insulin resistance, better therapeutic strategies c ....Type 2 diabetes is caused by insulin resistance, a condition that is characterised by the inability of insulin to elicit its normal function to lower blood sugar levels.

Targeting Nicotinamide Adenine Dinucleotide Biosynthesis To Improve Metabolism

Summary
Nicotinamide adenine dinucleotide (NAD) is a cellular metabolite that regulates many biological processes. NAD levels decline with age and also in obesity and interventions that increase NAD levels produce favourable metabolic effects. In this proposal we will utilise a range of novel experimental models to define the molecular pathways that mediate the beneficial effects of NAD.

Summary
Diabetic complications including heart attacks, strokes, kidney disease and blindness appear to be related to the high glucose (sugar) level but how glucose itself induces end-organ injury remains to be fully determined. In this proposal it is suggested that the long-term damaging effects of glucose relate to its ability to damage the regulation of genes by directly affecting DNA and its covering known as histones. Specifically glucose, possibly by altering certain biochemical pathways called ox ....Diabetic complications including heart attacks, strokes, kidney disease and blindness appear to be related to the high glucose (sugar) level but how glucose itself induces end-organ injury remains to be fully determined. In this proposal it is suggested that the long-term damaging effects of glucose relate to its ability to damage the regulation of genes by directly affecting DNA and its covering known as histones. Specifically glucose, possibly by altering certain biochemical pathways called oxidation pathways, interferes with enzymes which affect the structure of DNA and related molecules resulting in altered expression of many proteins. One of these proteins known as NF kappa B is activated in diabetes, probably by mechanisms involving regulation of these enzymes which play a central role in modifying gene structure. By clarifying the exact mechanisms at a molecular level that mediate the effect of glucose on genes and proteins it will be possible to target these molecules and develop new treatments to prevent, retard or reverse the blood vessel complications that are so common in diabetes.Read moreRead less
My research focus is the physical and mental health of Australian women at midlife. Over the next 5 years I will address the management of severe menopausal symptoms, midlife depression and the neglected health needs of women during and after cancer treatment, organ transplant and severe persistent mental illness. I will also investigate novel treatment approaches for menopausal symptoms. I will work closely with relevant professional and community groups in planning, implementation and translat ....My research focus is the physical and mental health of Australian women at midlife.
