This project is about the way that the brain controls reproduction. It is important because there is no known cause for infertility in a significant number people with such a problem. The project should inform us on new ways to manage particular forms of reproductive failure.
Gonadotropin Inhibitory Hormone (GnIH); A Negative Regulator Of Reproduction
Funder
National Health and Medical Research Council
Funding Amount
$752,936.00
Summary
Gonadotropin inhibitory hormone (GnIH) is a short peptide of 8 amino acids that is produced by the brain and acts in a negative manner on brain and pituitary cells that control reproduction. This project aims to elucidate the role of GnIH in normal physiology and in states of stress and negative metabolic state. Work will be carried out in various species to define the function of the peptide and also to investigate ways that it can be utilised to prevent reproduction.
THE EFFECT OF STRESS AND ENVIRONMENTAL ENRICHMENT ON DISEASE PROGRESSION IN MESIAL TEMPORAL LOBE EPILEPSY

Funding Amount
$578,201.00
Summary
Mesial temporal lobe epilepsy, the most common form of drug-resistant epilepsy in adults, is a progressive neurodegenerative condition for which there is currently no effective disease modifying treatment. This proposal will explore whether co-morbid stress accelerates disease progression in MTLE, and whether targeting stress pathways by medical and environmental manipulations can mitigate against this.
PACAP: The Mechanism Underlying Sleep Apnoea-induced Hypertension

Funding Amount
$505,117.00
Summary
10% of Australians suffer from sleep apnoea; a cause of high blood pressure. Untreated, high blood pressure causes heart failure, kidney failure and stroke. A major cause of high blood pressure is an increased amount of nerve activity that controls the heart and blood vessels. In this proposal we will investigate how a brain chemical, called PACAP, affects nerve activity and blood pressure in a model of sleep apnoea. This information may lead to new and better treatments for high blood pressure.
Functional Analysis Of A Novel Genetic Mouse Model For Congenital Growth Hormone Deficiency
Funder
National Health and Medical Research Council
Funding Amount
$519,131.00
Summary
Pituitary Hormone deficiency is not uncommon and is associated with poor growth, metabolism and fertility. Some cases of this disorder arise due to genetic changes that compromise the ability of the pituitary gland to make or secrete growth hormone (GH). Using cutting-edge genomics technology, we have generated a new genetic mouse model of GH deficiency. The aim of this project is to understand the function of this novel GH _regulating gene in mice and in humans.
Investigating A Novel Agent To Limit Brain Injury And Post-stroke Complications

Funding Amount
$412,429.00
Summary
Stroke is a leading cause of morbidity and mortality worldwide, but treatment options remain limited. The goal of this research project will be to examine the potential of new agent to protect the brain against stroke and to also treat complications that typically occur after stroke including infection and weight loss. It is anticipated that this project will ultimately lead to the development of an effective stroke therapy.
Regulation Of Growth Hormone Profile By Metabolic Balance: Neuronal, Neuroendocrinal And Molecular Mechanism

Summary
Obesity is associated with a reduction in growth hormone secretion. As growth hormone maintains muscle mass at the expense of fat this may further promote the obese condition. This project will determine the physiological role of ghrelin, a hormone that signals hunger, in maintaining growth hormone secretion under normal, fasting and obese conditions. Clarification of the role of ghrelin in regulating growth hormone secretion may aid in the development of pharmacological agents to assist and mai ....Obesity is associated with a reduction in growth hormone secretion.

How The Environment And Epigenetics Affect The Brain Disease Gene, MAPT.

Summary
Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether thi ....Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease.

These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether this process will have an impact on these diseases.Read moreRead less
Defining The Changes In Cell Biology Caused By PRESENILIN Truncations Associated With Different Diseases

Summary
Truncations of the PRESENILIN genes in humans can cause two very different diseases: inherited, early onset Alzheimer’s disease (familial Alzheimer's disease) and a skin disease named inherited Acne Inversa. One truncation is also involved in the non-inherited, late onset form of Alzheimer’s disease. Why do these different truncations produce different diseases? Investigating this question will teach us more about the molecular bases of these different diseases.

Human Olfactory Neurosphere-derived Cells: A Novel Cellular Model For Parkinson's Disease.

Funding Amount
$365,126.00
Summary
ParkinsonÍs disease (PD) is an incurable, brain disease that affects 75,000 Australians with great societal cost. We are working on adult stem cells called (hONS) grown from peopleÍs olfactory mucosa (in the nose) as a research tool to study PD. Our project examines differences seen in hONS from people with PD and determines how certain cellular processes impact on the function of these cells. This work will enhance our understanding of the biology of PD and identify new targets for therapies.
