Summary
Inhibiting malaria transmission is a critical step towards global eradication of this deadly disease. This proposal aims to understand the mechanisms regulating the expression of genes which control the differentiation of the transmission stages of malaria parasites. Such pathways are prime targets for novel anti-malarial drugs.
Hyper-sensitivity Of The Circadian System To Light In Delayed Sleep Phase Disorder

Summary
Delayed Sleep Phase Disorder (DSPD) is a circadian rhythm sleep disorder characterized by a difficulty in initiating sleep at night and difficulty in waking at times required for work or school. It is associated with excessive daytime sleepiness, reduced academic and work performance, increased anxiety and depression and reduced quality of life. This study examines increased sensitivity of the brain's 24-hour biological clock to light as a cause of the abnormal timing of sleep in DSPD.
Defining Factors That Contribute To Individual Diversity In The Diet-health Axis

Summary
There is a complex interplay between nutrition and genetics such that one diet maybe good for some but not for others depending on genetic makeup. Preliminary experiments in flies and mice support this. We found that for some flies, diets high in fat are harmful resulting in short life but certain flies resist the harmful effects of fat and live a longer lives. We propose to unravel the gene-environment interaction and determine which genes might lead to optimal health outcomes on certain diets.
Circadian Mechanisms For Sex Differences In Shift Work Tolerance

Summary
It is well-established that women respond more poorly than men to shift work schedules, having more health complaints, more drowsiness and more accidents at work than men. The physiological cause of this sex difference is not known. Our research suggests that differences in the circadian rhythms of women and men may promote shift work intolerance in women. This study is designed to examine sex differences in the effect of office-level light on the biological clock during a simulated night shift.
HDL Elevation And Glucose Metabolism: A Mechanistic Proof-of-Concept Intervention Trial In Pre-Diabetes

Funding Amount
$507,974.00
Summary
This clinical trial will investigate a new treatment strategy for type 2 diabetes. Building on our novel discovery that HDL (good cholesterol) lowers blood glucose, we will test whether HDL elevation over a month with a new drug (RVX-208) can improve glucose control in patients with pre-diabetes. If positive, these studies will support new therapeutic approaches to raise levels of circulating HDL for indications beyond vascular disease to manage type 2 diabetes.
Does Exercise Increase Skeletal Muscle Insulin Sensitivity Via Nitric Oxide?

Summary
Almost one in four Australian adults have either diabetes or impaired glucose metabolism. A major benefit of exercise is that it increases the sensitivity of muscle to insulin for many hours after the exercise is completed. We don't fully understand the mechanisms that exercise increases muscle insulin sensitivity. If we discover how nitric oxide production during exercise is involved, drugs that mimic these exercise effects may be designed to benefit those with diabetes.
Regulation Of Hypothalamic Insulin & Leptin Signalling By TCPTP
Funder
National Health and Medical Research Council
Funding Amount
$758,504.00
Summary
Insulin & leptin signal in the brain to lower blood glucose, suppress food intake, increase activity & increase energy expenditure. Obesity diminishes the abilities of insulin & leptin to signal. This proposal will determine if the enzyme TCPTP terminates insulin & leptin signaling in the brain. Our studies will provide insight into the molecular causes of obesity & may identify a novel therapeutic target for the treatment of obesity & type 2 diabetes.
Targeting Microtubules To Overcome Chemoresistance In Pancreatic Cancer

Funding Amount
$594,336.00
Summary
Pancreatic cancer is a devastating disease with a dismal prognosis because it is extremely resistant to chemotherapy agents. We plan to examine the expression of proteins called microtubules in pancreatic cancer and assess their role in drug resistance. It is anticipated that the findings of these studies will lead to the development of effective approaches to sensitise the cancer cells to chemotherapy agents.
The Functional Organisation And Signals Of Motion Sensitive Neurons In The Middle-temporal Area Of Visual Cortex
Funder

Funding Amount
$405,337.00
Summary
Some nerve cells in the cerebral cortex are very sensitive to visual motion. These neurons direct eye movements and provide motion perception, but the "neuronal code" they carry is poorly understood. We will address this basic question in experimental studies of the primate visual system. This project will help us understand visual performance; poor motion vision is an early indicator of many neurological disorders and this knowledge can help develop methods for their detection and diagnosis.
