Glucose is a critical fuel for living organisms and its presence in the gut triggers nerves that slow stomach emptying. However, little is known of how glucose is actually detected in the gut. We have established that sweet taste molecules of the tongue are also present in the gut, where they may detect glucose. This research will measure the expression and function of these molecules in the gut of humans and mice, and reveal key information on their potential as targets in health and disease.
The migration of cancer cells (metastasis) is responsible for most cancer deaths. Central to this is dynamic organisation of the actin cytoskeleton _ an internal structure that provides cell shape and enables movement. We have identified a family of small molecules (called miR-200) that regulates this actin cytoskeleton through specifically downregulating various genes. We are investigating the nature of these genes and their role in cell motility _ an underlying pre-requisite of metastasis.
A Genome-wide Association Scan To Identify Genetic Risk Factors For Sight Threatening Diabetic Retinopathy

Funding Amount

Summary
Diabetic eye disease is an important complication of diabetes that can lead to blindness. Very little is known about how diabetes causes eye disease, but genetics is known to play a role. We aim to identify genes that contribute to eye disease in diabetes patients. We will compare genes between patients with diabetes with and without severe diabetic eye disease using cutting edge genomic technology. We hope to be able to better predict risk of blindness and to move towards novel treatments.
Identification Of Genes For X-linked Mental Retardation.

Funding Amount

Summary
We propose to identify novel heritable causes of intellectual disability using 22 large and well-characterised families from Australia. In these families we have refined the location of the genetic defect to the chromosome X and excluded the contribution of all so far known genes. We will achieve this using the technology of massive parallel sequencing. At the completion of the project we will have identified novel causes of intellectual disability and devised tests to identify them.
Dissecting The Pseudoexfoliation Syndrome With Complementary Genetic, Proteomic And Biophysical Strategies

Summary
Pseudoexfoliation syndrome (PEX) is an eye condition in which flaky material deposits in the eye, greatly increasing the risk of cataract and glaucoma which can lead to blindness. PEX is also associated with heart disease, strokes and aneurysms. Cataract surgery in PEX patients has a higher rate of complications. In this project we will determine the nature of PEX material and why it forms. This knowlege will facilitate better diagnosis and treatment of PEX preventing associated blindness.
Development Of Diagnostic Tools To Characterise Predictors Of Therapeutic Outcome In Severe Constipation
Funder
National Health and Medical Research Council
Funding Amount
$433,999.00
Summary
This project will use fibre-optic technology to create detailed high resolution maps of colonic motor patterns in both health and in patients with severe constipation. The data will be used in combination with actual patient symptoms to help identify specific markers of disease that can differentiate sub-types of constipation and ultimately guide and improve treatment in constipated patients
