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.
Elucidating The Role Of MiR-196 In Formation Of The Axial Skeleton

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.
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.
Gene Mining For Novel Molecular Determinants Of The Skeleton

Summary
Musculoskeletal conditions affect over 6 million Australians and research has shown that genetic background strongly influences development of these disorders. This project will identify genes that have a role in controlling bone and joint architecture. Identification of these genes will assist in the development of treatments targeting bone disorders and allow screening for these genes to provide an opportunity for people to take preventative action to improve bone and joint health.
Bridging The GAPP Between The Laboratory And Clinic To Prevent Gastric Adenocarcinoma And Proximal Polyposis Of The Stomach (GAPPS).

Summary
Gastric Adenocarcinoma and Proximal Polyposis of the Stomach (GAPPS) is an inherited form of gastric cancer. Affected patients develop a large number of gastric polyps and are at risk of gastric cancer in their 30s. The only effective treatment is to surgically remove the stomach. Gastrectomy is, however, associated with significant post-operative complications. We will use laboratory and mouse models of GAPPS to identify acceptable new approaches to prevent cancer in these patients.
Role Of Snail Family Proteins In Male Fertility And Testicular Cancer

Summary
Male fertility requires production of healthy sperm in the testis. This project builds on our discoveries that testicular cells regulate gene activity via the Snail family of proteins during sperm development, and that interruption of their activities reduces fertility in mice and fruitflies. Snail proteins are also active in cancer cells. We propose to study the precise steps in sperm production affected by Snail proteins and how they affect the progression of testicular cancer.
How are memories stored in the brain? We know much about the brain regions involved in memory storage but we know little or nothing about how individual memories are represented and stored within those brain areas. The purpose of this project is to label and manipulate the specific subsets of brain cells that store individual memories. We will label memory-bearing cells in multiple brain regions and then ask how the connections between those cells encode learned information in the brain.
Identifying The Pathological Mechanism Of PCDH19-Girls Clustering Epilepsy

Funding Amount

Summary
Changes in the PCDH19 gene are a relatively common cause of epilepsy. To better understand the basis of this disorder, we have developed unique mouse models that mimic the genetic changes and symptoms of this condition. We will perform careful analysis of brain development in these models to determine the primary cause of this condition. These experiments will create greater understanding of how changes in PCDH19 cause epilepsy in girls and facilitate the development of new treatments.
Functional Analysis Of A Novel Genetic Mouse Model For Congenital Growth Hormone Deficiency

Funding Amount

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.
