The Role Of Accessory Subunits And Assembly Factors In The Biogenesis Of Respiratory Chain Complex I

Summary
The mitochondrial respiratory chain produces most of the energy required for our cells to grow and function. Complex I is the first enzyme of this chain and its defects are the most prevalent cause of mitochondrial disease, which often results in infant fatality. Defects in complex I have also been associated with Parkinson's disease and oxidative stress. This study will provide important new information into how complex I is built and what goes wrong to cause disease.
Characterising Complex I Function And Dysfunction In Mitochondrial Disease

Summary
The cells in our body produce energy in power plants called “mitochondria”. Mitochondrial disease affects 1 in 5000 live births. Currently there is no cure, but understanding how the genes mutated in mitochondrial disease work is an important step to finding one. Previous research relied on patient samples; however we will employ new technologies allowing us to rapidly model mitochondrial disease in a laboratory setting.
Signaling Pathways To Enhance Potency Of AMPK-targeting Drugs

Funding Amount
$661,966.00
Summary
Sedentary lifestyles and consumption of high energy foods has led to epidemics of obesity-related metabolic diseases that place enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK) which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Our goal is to improve AMPK drug potency by identifying novel processes that sensitize AMPK to drugs.
Assembly And Misassembly Of Mitochondrial Respiratory Chain Complex I

Summary
Mitochondria are the powerhouses in our cells. They burn the carbon fuels we eat and store the energy by making ATP that is used for functions such as muscle contraction and triggering of nerves. Mitochondrial Complex I is a molecular motor that helps to make ATP. “Mitochondrial disease” is often seen when Complex I is not built properly and this results in early childhood death. In this project we will study how Complex I is built and how the mitochondria responds to assembly problems.
Transcription-based Identification Of Insulin Resistance Subtypes

Summary
A key feature of type 2 diabetes is the failure of metabolic tissues such as muscle and fat to respond to normal levels of insulin. This 'insulin resistance' is caused by a number of mechanisms. We will use cutting-edge technology to identify small sets of genes that define each variety of insulin resistance. These gene sets will be used to diagnose sub-types of insulin resistance and will facilitate the development of personalised therapies to effectively treat individuals with type 2 diabetes.
Integration of Cellular Gene Regulation Processes. This research program aims to identify specific transcriptional regulatory networks in yeast, to determine how some of these networks interact with each other and within these networks to identify the roles of genes whose functions are currently unknown. It will identify systems regulating genes concerned with one-carbon metabolism, cellular responses to oxidative stress and developmental changes associated with meiosis. It will provide a fra ....Integration of Cellular Gene Regulation Processes. This research program aims to identify specific transcriptional regulatory networks in yeast, to determine how some of these networks interact with each other and within these networks to identify the roles of genes whose functions are currently unknown. It will identify systems regulating genes concerned with one-carbon metabolism, cellular responses to oxidative stress and developmental changes associated with meiosis. It will provide a framework to test regulatory network models and to analyse the molecular basis of interactions between control systems. This research will eventually provide the ability to predict how cells respond to drugs and other environmental stimuli.Read moreRead less
Characterisation of the novel mitochondrial protein (CABC1/ADCK3) and its role in protecting against oxidative stress. This is the first detailed characterisation and mechanistic study on a protein that protects against oxidative stress and neurodegeneration. Demonstrating the basis for this oxidative stress and its possible contribution to the cellular phenotype will be of benefit in understanding the disease process and ultimately designing approaches to minimise oxidative stress.

Demonstrating the basis for this oxidative stress and its possible contribution to the cellular phenotype will be of benefit in understanding the disease process and ultimately designing approaches to minimise oxidative stress. An investigation of this protein presents an opportunity for the investigator to work at the forefront in this field adding to Australia's scientific leadership in the area. It also represents an ideal project for post-graduate training and is a collaboration between groups in Brisbane and Melbourne. Read moreRead less

Biological research is playing an increasingly important role in keeping agriculture internationally competitive and helping to unravel the basic mechanisms underpinning plant and animal health. This collaborative research equipment will greatly enhance and extend our existing functional genomic facilities in WA, allowing robust pre-fractionation of samples for directed proteomic analysis within complex systems and allowing accurate and sensitive measurement of gene expression. Both of these are critical for analysis of low abundance components involved in signalling and regulatory functions in biological samples.Read moreRead less
