Summary
Gastric cancer is the 2nd most common cause of cancer-related death worldwide. Our laboratory has previously established clinically relevant mouse model of gastric cancers, and our preliminary results indicate a strong link between B cell tumor infiltration and gastric cancer progression. In this project, we aim to elucidate the role of B cells in gastric cancer and determine whether B-cell targeted therapy alone or in combination with chemotherapy can be beneficial against this malignancy.
The Effects Of The Western Diet On Cognition In Rats

Funding Amount
$689,326.00
Summary
An unhealthy diet can affect how we think. This project will identify mechanisms by which a western diet impairs cognition, and test ways of intervening to reduce the impact of diet on the brain. We will examine changes in inflammation, and markers of nerve growth in a critical brain region, the hippocampus, in response to different periods of diet. We will also test if the diet and our interventions affect the gut biota.
This Project will produce the first map of the brain mechanisms that motivate unhealthy food choices in obesity. This outcome can inform the development of novel treatment approaches for obesity that modify the preference for high-calorie, unhealthy foods by changing the neural bases of such preferences.
Transgenerational Effects Of Male Obesity - Mechanisms And Interventions
Funder

Funding Amount
$829,143.00
Summary
Childhood obesity is associated with obesity in either parent, and obese children tend to become obese adults, forming an intergenerational cycle that promotes obesity. We have identified paternal obesity as an important novel target for intervention to stop the progression of the obesity epidemic. This project investigates supplementation of obese fathers with folate to prevent the adverse impact of paternal obesity on subsequent generations.
The Role Of Brain Inflammation In Leptin Resistance

Summary
Melanocortin neurons control body weight and are regulated by leptin. In obesity leptin cannot regulate the melanocortin system. We will test if leptin action on melanocortin neurons is limited by increased expression of suppressor of cytokine signalling 3 (SOCS3) in obese mice. As an alternative we will test if there are changes in the blood brain barrier, or an increased density of support and immune cells around melanocortin neurons of obese mice that might restrict inputs to these neurons.
Cardiometabolic Risk Trajectories From Childhood To Midlife: Finding Pathways To Better Health

Funding Amount
$1,531,987.00
Summary
Using data from a large cohort of Australian children followed for over 30 years, this study will investigate how weight status and physical fitness from childhood to adulthood determine early markers of cardiovascular disease and type 2 diabetes (cardiometabolic disease) in midlife. It will provide much needed evidence to address the high prevalence of cardiometabolic disease risk factors in young Australians through better targeted disease prevention and early clinical intervention strategies.
Assessing The Impact Of A Multi-component Intervention To Improve Dietary Intake Of Indigenous Australian Children And Their Families Living In Remote Communities

Funding Amount
$1,455,043.00
Summary
Sugar-sweetened beverage consumption seems to contribute to obesity and diabetes. We aim to test the impact of multi-component intervention including a school-based nutrition education program combining high levels of parental involvement plus a supportive environment to reduce sugar-sweetened beverage consumption and improve healthy eating among Indigenous Australian children and their families living in remote communities.
Unravelling The Impact Of An Energy-rich Environment On Susceptibility And Resistance To Obesity

Funding Amount
$796,754.00
Summary
Obesity in Australia is at a crisis point. It is clear that energy-rich environments and an individual’s genes leads to excessive weight gain, but what we don’t understand is why some individuals are more prone to this than others. Comprehending this biological regulation is imperative if we are to develop more effective drug or dietary treatments to abate this disease. Thus it is the aim of this grant to dissect the biological/genetic/possible epigenetic perturbations leading to common obesity.
Improving Weight Loss By Intermittent Use Of Very Low Energy Diet: The TANGO Diet Trial (Temporary Phases Of Accelerated Weight Loss For Noticeably Greater Outcomes)
Funder
National Health and Medical Research Council
Funding Amount
$660,736.00
Summary
Very low energy diet (VLED) is being increasingly used for the treatment of obesity, but the resultant weight loss is usually transient, partly because it induces powerful adaptive responses that inhibit weight loss and promote regain. We have shown that 'taking a break from dieting' for 2 weeks reduces these adaptive responses. In this project we will thus test whether weight loss outcomes with VLED can be improved via intermittent use, where periods on the VLED are alternated with 'breaks'.
Train High Eat Low For Osteoarthritis (THE LO Study): A Randomised Controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$592,496.00
Summary
Generic lifestyle prescriptions are both insufficient and unrealistic in a cohort that is obese and markedly impaired in mobility and activity level due to lower extremity pain and abnormalities of gait. Therefore this study will design and test for the first time a novel, evidence-based lifestyle modification program which targets all of the treatable etiologic factors in knee OA: low Glycemic Index/Glycemic Load (GI/GL) diet, high intensity strength training and gait training.
