Alteration Of Glucose Metabolism By GPCR Activation

Summary
In type 2 diabetes the effect of insulin to stimulate glucose transport in fat cells and skeletal muscle is impaired so there is great interest in identifying insulin-independent mechanisms that increase glucose transport. Several G protein-coupled receptors (GPCRs) regulate glucose transport independently of insulin but the mechanisms involved in these effects are largely unknown. This project investigates how GPCRs regulate glucose homeostasis and will evaluate them as potential treatments.
Investigate The Role For Dok Adapter Proteins In Thrombosis And Haemostasis.

Summary
Blood platelets play a key role in blood clot formation, prevention of bleeding and are the principal elements contributing to thrombosis leading to heart attack and stroke. Numerous studies have defined pathways promoting platelet activity, however less is known about their negative regulation. In this fellowship I will examine the role for proteins, Dok2 and Dok1, in the negative regulation of platelets, hoping this leads to development of novel therapeutics for prevention of cardiac disease.
Investigating B Cell Development, Maintenance And High-affinity Antibody Production By ENU Mutagenesis

Funding Amount
$408,388.00
Summary
B cells are essential for the protection against infections. This application aims to identify new genes that are crucial for the development or function of B cells and will investigate how mutations in newly discovered genes contribute to defects in the development and function of B cells and the pathogenesis of B cell leukaemia.
How Sweet It Is: Diagnostic Clinical And Experimental Glycoproteomics

Funding Amount
$473,477.00
Summary
Most human proteins are modified by the addition of complex sugar groups, which are important for the correct function of these key biological molecules. This fellowship will develop a suite of robust mass spectrometry glycoproteomic analytics for use in conjunction with clinical cohorts, model systems and in vitro biochemistry to investigate fundamental aspects controlling N-glycosylation in disease and translation to clinical diagnostics.
The pathology of many acute and chronic diseases associated with the inappropriate activation of genetically encoded programmed cell death pathways, such as sepsis, stroke, diabetes and neurodegeneration, is linked to detrimental inflammation. This project will accurately define at the molecular level how programmed cell death triggers inflammatory responses, and use this knowledge to test novel and next-generation therapeutic strategies in inflammatory-driven diseases.
Defining The Mechanisms That Control Exocytosis And Cell Signalling In Health And Disease.

Funding Amount

Summary
This research focuses on pathways regulating nervous communication and hormone release. It centres on proteins that regulate this process and on the function of specific endocrine cells in health and disease. It uses unique research tools developed in this laboratory enabling the study of mechanisms regulating cell signalling. Through this research I aim to identify how the cells in our body communicate with each other and how this relates to diseases such as type 2 diabetes.
Understanding Allosteric Modulation And Biased Signalling At Family B GPCRs

Funding Amount

Summary
Family B GPCRs are therapeutic targets for drugs treating osteoporosis, hypercalcaemia, Paget’s disease, type II diabetes and are being actively pursued for other diseases that represent major global health burdens. Despite huge financial input, there are no orally available drugs that act on these receptors. This speaks to a lack of mechanistic understanding of how they work. My research focuses on addressing this question and how to exploit these receptors to design and identify better drugs.
The Molecular Mechanisms Of Abscission To Complete Cytokinesis
Funder
National Health and Medical Research Council
Funding Amount
$380,558.00
Summary
Cytokinesis is the final stage of cell division that produces two daughter cells. Incorrect localisation and modification of proteins that regulate this process cause cell division errors potentially leading to cancer. This project will characterise how key cytokinesis proteins co-operatively function to complete cytokinesis. This research will increase our understanding of the cell division errors that contribute to cancer development, ultimately identifying new targets for cancer therapy.
