LIFEPATH: Life-course Biological Pathways Underlying Social Differences In Healthy Ageing
Funder

Funding Amount
$470,466.00
Summary
Healthy ageing varies across society due to environmental, behavioural and social circumstances that affect peoples’ lives. To improve our ability to change this we will investigate suspected biological mechanisms over the life course. Using repeated blood samples collected during a large prospective study, we will measure a very large number of biological markers and analyse these combined with lifestyle and behavioural information to identify the modifiable predictors of healthy ageing.
Nutrition And Rehabilitation In Advanced Cancer Patients

Summary
This preliminary project aims to evaluate associations between cancer cachexia, psychosocial factors and cytokine levels in blood. The final decline of most patients with advanced cancer is associated with the cancer cachexia syndrome, triggered in part by cytokine release. Measuring cytokines may enable identification of patients about to enter this final stage. Further, factors like mood and social support appear to alter cytokine levels. The associations established by this study may point to ....This preliminary project aims to evaluate associations between cancer cachexia, psychosocial factors and cytokine levels in blood.

Targeting Inflammation As A Biomarker And Treatment For Alzheimer's Disease

Funding Amount
$718,920.00
Summary
We are undertaking the challenge of using and developing novel animal models in parallel with studies on affected human subjects to elucidate the underlying molecular mechanisms linking the changes in inflammation to amyloid plaques, neurofibrillary tangles and cognitive decline. Understanding these mechanisms will allow us to define the biological pathways involved in the onset and progression of Alzheimer’s disease, and identify potential biomarkers and therapeutic targets.
Biomarkers For Risk And Outcomes Of Type 2 Diabetes: A Discovery And Validation Approach In Australian And Chinese Subjects
Funder
National Health and Medical Research Council
Funding Amount
$599,489.00
Summary
The aim is to make better outcomes for people with Type 2 diabetes in Australia and China, by exploring various tests to improve prediction of diabetes progression, complication risk and treatment response. The team has data and samples from the Fenofibrate Intervention and Event Lowering in Diabetes Trial and from the Shanghai Diabetes Study. This approach is very time and cost-effective. We will also study animal models to understand mechanisms of diabetes damage, and test new treatments.
Bacterial Metabolite Mediated Regulation Of The Immune And Metabolic Systems
Funder
National Health and Medical Research Council
Funding Amount
$303,374.00
Summary
The cellular and molecular events that underpin metabolic syndrome diseases, such as diabetes, fatty liver, etc are poorly understood. However recent advances provide new clues. First, the immune system is intimately connected to metabolism. Second, the gut microbiota, and its metabolites such as acetate and butyrate are also important. These metabolites induce epigenetic changes in cells. We will study how metabolites induce molecular changes epigenetically, and how this controls metabolism.
Il-18 helps to prevent obesity and type 2 diabetes, however the process by which this cytokine is activated to prevent obesity is not known. We have now found the pathway that drives to this process. This project will seek to extend our observations to show how this can be targeted therapeutically to treat obesity and type 2 diabetes.
Dissecting The Host X Diet X Microbiota Interactions Supporting Sustainable Weight Loss In Obesity
Funder
National Health and Medical Research Council
Funding Amount
$252,305.00
Summary
There is increasing evidence that the gut microbiome plays an important part in predisposing to obesity. This project seeks to identify whether such an obesogenic microbiota may also influence our ability to maintain weight loss after a period of caloric restriction. Further, we investigate whether dietary fibre can be used to reshape gut microbial population structure and function so as to support sustained weight loss on return to a normal dietary regimen using an obesogenic rat model.
Dementia Associated To Diabetes: Prevention Through The Modulation Of Cerebrovascular Integrity
Funder
National Health and Medical Research Council
Funding Amount
$719,770.00
Summary
Diabetic insulin resistance is reported to induce cognitive decline and dementia. An accumulating body of evidence suggest that compromised integrity of neurovascular unit and following changes in cerebral lipid homeostasis may be centrally involved in the neurodegeneration and cognitive deficits. Therefore, the project aims to prevent the insulin resistance-associated cognitive impairment by modulating the integrity of cerebrovasculature and lipid homeostasis.
