Summary
This project will contribute to understanding mechanism of vitamin D action within bone to modulate bone resorption and offers the exciting prospect of identifying the mechanism by which an adequate vitamin D status can reduce the risk of osteoporotic hip fractures. Thus, this project has great potential to improve community health by being able to recommend vitamin D supplementation made on the basis of maintaining normal bone cell function with psarticular reference to modulating bone resorpti ....This project will contribute to understanding mechanism of vitamin D action within bone to modulate bone resorption and offers the exciting prospect of identifying the mechanism by which an adequate vitamin D status can reduce the risk of osteoporotic hip fractures.

Summary
Malaria is estimated to cause 1.2 million deaths per year. The malarial parasite has developed resistance to most drugs and new drugs are needed. We aim to mimic the protective red blood cell diseases common in human populations in malarial endemic areas by identifying host targets that are important in parasite growth.

Summary
Exquisite regulation of gene expression is a fundamental principle underlying growth and development of an embryo as well as homeostasis in the adult. Following the identification of hundreds of microRNAs within the genome which act to modulate gene expression, the challenge and the goal of these studies, is to identify individual microRNAs which contribute significantly to bone formation in the developing embryo.

Summary
Germ cells generate sperm in males or oocytes in females. In males, germ cell numbers are tightly controlled in the embryo, with too few germ cells causing infertility, and unrestrained germ cell numbers leading to testicular cancer. We have discovered a molecular mechanism that regulates germ cells in the embryo, and propose to study in mice how this regulation is accomplished and the consequences of defective regulation, in order to learn more about how infertility and testis cancer arise.
Functional Analysis Of A Novel Genetic Mouse Model For Congenital Growth Hormone Deficiency

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.

Summary
Brain tumours are the most common cause of cancer-related death in children and the tumour medulloblastoma is the most frequent. There is a need to develop new therapeutic approaches to treating medulloblastoma through the development of new drugs to directly target the tumour. This research has identified new genes that are good candidates as drug targets for treating medulloblastoma.
Dysfunctional blood vessel growth is an important mechanism of many congenital vascular diseases and other postnatal diseases such as ischemia and cancer. Cerebral cavernous malformations (CCMs) are common vascular disease in brain that cause strokes and seizures in midlife. Due to their location in the brain, CCMs are virtually untreatable, making the development of novel therapies a priority. This proposal aims to understand how the molecular players underlying this brain vascular disease cont ....Dysfunctional blood vessel growth is an important mechanism of many congenital vascular diseases and other postnatal diseases such as ischemia and cancer.

Due to their location in the brain, CCMs are virtually untreatable, making the development of novel therapies a priority. This proposal aims to understand how the molecular players underlying this brain vascular disease control blood vessel function and growth.Read moreRead less
Chronic pain will affect most of us at one point in our life, and there is a need for new drugs to manage this condition. The goal of this project is to use a combined state-of-the-art genetics approaches in fruit flies, mice, rats, and humans, to identify and validate new genes that contribute to chronic pain, with the clear long term possibility to develop new strategic therapies to treat chronic pain disease.
6% of Australian men are infertile. Of these cases 50% are thought to be genetic in origin. Within this project we will replicate high-confidence genetic variants associated with human male infertility in the mouse. Doing so will allow the assignment of definitive genotype-phenotype correlations and the formulation of high confidence advice for clinicians and patients. It will also provide a means to define the mechanism of action and the tools for future pro-fertility treatments.

Summary
All cells in the body require blood vessels for the provision of nutrients and waste-removal. A deficiency of vessels prevents proper healing whereas an overabundance is a hallmark of diseases such as cancer and macular degeneration. This research will investigate a novel gene that is essential for new vessel growth. The project aims to understand the mechanism of how this gene functions. Ultimately, the research aims to inform therapeutic development for stimulating or inhibiting vessel growth.
