The neuronal synapse is very tightly regulated by proteins that control both the timing and the amount of neurotransmitter release and neuronal stimulation. Defects in this synaptic signal are linked to diseases including epilepsy, autism and dementia. In this study we will determine the molecular details of how proteins called SNAREs control neurotransmission in the human brain.

Summary
Proper functioning of the nonsense mediated mRNA decay (NMD or 'mRNA police') is crucial for any cell to ensure normal development and function. When NMD is compromised the outcome is learning and memory problems, autism or schizophrenia. Under this project we study malfunctioning NMD using stem and neuronal cells derived from patients' skin cells. Some of the affected genes might be considered for therapeutic interventions. NMD is relevant to 1000s of human disorders and as such it is of fundam ....Proper functioning of the nonsense mediated mRNA decay (NMD or 'mRNA police') is crucial for any cell to ensure normal development and function.

Uncovering New Epigenetic-based Regulatory Mechanisms Of Gene Expression: Novel Links Between Histone Variants, RNA Function And Disease

Summary
It is estimated that greater than 90% of human genes undergo alternative RNA splicing, which can explain how protein diversity is achieved with a limited number of genes. However, how alternative splicing patterns are established remains poorly understood but is an important question given that 15-50% of human disease mutations are associated with changes to the splicing patterns of RNA. We have uncovered a new splicing mechanism, which involves changing the way DNA is packaged in a cell.
Molecular Control Of Interneuron Development And Function In Health And Disease

Summary
This project will study the changes that occur in neurons, during normal brain maturation and in pathology. We hypothesise that early signs of brain malfunction can be detected in neurons before symptoms appear. The role of a gene will be studied during development and disease in a mouse model of autism, in order to identify the molecular and electrical signs of abnormal activity. This research will ultimately enable us to propose new strategies to treat symptoms of brain disease.
Identifying Cell Type Specific Biomarkers Of Recurrent Oral Squamous Cell Carcinoma And Mapping Cancer-stroma Interactions Using Single Cell Biology And Cell-to-cell Communication Networks

Summary
Cancer is a major cause of death in Australia. Despite advances in our understanding of the mutations that occur and the sets of genes expressed in cancer we have a major gap in our understanding of what is happening within tumours. Using new single cell technology we will generate new molecular portraits of cancers that give us understanding of the sets of genes expressed on individual cancer cells, the normal cells within a tumour and how they interact with cancer cells to form a tumour.
Investigating A Novel Genetic Regulator Of Cardiac Rhythm

Summary
Cardiac arrhythmias affect approximately 5% of the population and have a high association with sudden death. Whilst the cause of cardiac arrhythmia is complex, we know that genetic mutations play a role however we don't know all the genes important for cardiac rhythm. It is imperative that we identify all the genes in this process, so we can determine which mutations cause arrhythmia. We have identified a new gene that causes cardiac arrhythmia and seek to understand how it functions.
The FIELD trial, one of the largest type 2 diabetes studies world-wide, involving 9795 people over five years, demonstrated that the blood fat lowering drug fenofibrate protects against diabetic eye, kidney and nerve damage and some cardiovascular events. The FIELD NOMAD Study will identify novel molecular and biochemical markers of diabetes complications and treatment response in at least 1000 subjects with diabetes. Results are expected to improve diabetes care and develop new treatments.
Integrating Immunity And Genetics In Follicular Lymphoma To Establish A Prognostic Score Fit For The Modern Era

Summary
Follicular lymphoma (FL) is divided into early and advanced stages. Early stage FL is frequently cured, but there is no way to identify who will be cured and who won't. By contrast advanced stage FL is incurable. Our unique access to well-annotated clinical trial and population based cohorts allows us to perform a detailed biological comparison of early and advanced FL, to gain a deeper understanding of the impediments to eradicating the disease, and to predict outcome to conventional therapy.
Epigenetic Regulation Of Cell Lineage Differentiation In The Early Embryo

Funding Amount
$440,983.00
Summary
Exposure of embryos to a range of stresses can increase the predisposition to chronic diseases of adulthood. Stressing embryos at critical stages of development cause errors in reorganization of the nucleus that are required for normal gene expression. These errors are propagated into adulthood. This project will map the normal processes of nuclear reorganization and define how stress to the embryo changes this process, allowing an understanding of the causes of some important chronic diseases.

Summary
This proposed research investigates the bidirectional relationship between inflammation in the central nervous system (CNS) and depression during normal aging processes. It is assumed that inflammatory processes in the CNS will induce the development of depression and vice versa, that depression will lead to increased inflammation in the body. In addition, the research will study the genetic background and gene expression of inflammation contributing to both aging processes and the onset of depr ....This proposed research investigates the bidirectional relationship between inflammation in the central nervous system (CNS) and depression during normal aging processes.
