Summary
Malaria is a debilitating parasitic disease that is responsible for the deaths of about two million children each year. As drugs, such as chloroquine, become increasingly useless due to the development of parasite resistance, there is an urgent need to understand the mode of action of these antimalarials so that replacement drugs can be designed. We propose to test the hypothesis that chloroquine acts by interfering with the detoxification of the by-products that are produced when the parasite f ....Malaria is a debilitating parasitic disease that is responsible for the deaths of about two million children each year. As drugs, such as chloroquine, become increasingly useless due to the development of parasite resistance, there is an urgent need to understand the mode of action of these antimalarials so that replacement drugs can be designed. We propose to test the hypothesis that chloroquine acts by interfering with the detoxification of the by-products that are produced when the parasite feeds on haemoglobin. We propose that the parasite develops resistance to chloroquine by excluding either the drug or the toxic by-products from the site of action. We further propose that proteins of the digestive vacuole of the parasite are involved in the development of resistance to chloroquine. We plan to identify and characterise these proteins and to use this information to design novel antimalarial drugs.Read moreRead less
Charting The Interface Between Cellular Metabolic States And Gene Regulation

Funding Amount
$653,196.00
Summary
The research successes of Molecular Biology and Biochemistry have given us detailed pictures of the regulatory and metabolic states of cells and tissues, yet we know little about how these states affect each other. We hypothesise the existence of regulatory interactions between ribonucleic acids, enzymes and metabolites to connect gene expression and metabolism. We will employ novel RNA Biology methods to discover such regulatory interactions in medically important cellular contexts.
Characterising The Topology And Function Of The Human M5C RNA Methylome

Summary
The role of the modified base 5-methylcytosine (m5C) as an epigenetic mark in DNA is well appreciated and intensely studied. By comparison, the cellular functions of the same base modification in RNA molecules, which function as working copies of the DNA genome, are poorly understood. This project will apply next generation sequencing technology to chart the occurrence of m5C in eukaryotic cellular RNAs and endeavour to unravel its function(s) in human biology and cancer.
Our centre combines clinical and laboratory expertise to tackle autoimmune, inflammatory, and immune deficiency diseases. Starting from a genetic discovery platform, we aim to understand precisely how the immune system goes wrong in each individual patient to cause disease. This approach will make diagnoses more accurate and tailor treatment to each patient. The centre's approach should provide a template for the implementation of genomics and personalized medicine into routine clinical practice
Understanding Gene Regulation In Disease Using High Throughput Sequencing

Summary
While genetics refers to the gene sequence, or DNA code, epigenetics refers to all the other factors that control how and when each gene is expressed. New technologies with the ability to sequencing billions of bases of DNA are now being used to study epigenetics. However the data sets are vast and complex. I use statistical and computational approaches in the emerging field of bioinformatics to make sense of this data and relate genome wide disruption of epigenetic marks to diseases.
The Landscape Of Cancer Genes And Associations With Prognosis In Breast Cancer Diagnosed In Premenopausal Women
Funder
National Health and Medical Research Council
Funding Amount
$700,512.00
Summary
Using state of the art technology, the purpose of this project is understand the implications of known cancer mutations in breast cancer diagnosed in premenopausal ER-positive breast cancer. Mutations are abnormalities in the DNA of genes that can provide a signal for uncontrolled growth, a hallmark of cancer. The unique aspect of this project is use of tissue samples from patients who were diagnosed with breast cancer at a young age. This information will help us develop new treatments.
