Summary
Blood and lymphatic vessels are vital components of the cardiovascular system. Abnormalities in the growth and development of these vessels are associated with human disorders including cancer and cardiovascular disease. The focus of this application is to characterise the role of the ubiquitin protein ligase Nedd4 in vascular development, with the aim of identifying targets to which novel therapeutics for the treatment of blood and lymphatic vascular diseases could be generated.
Generation Of Renal Cells From Human Embryonic Stem Cells

$281,805.00
Summary
This proposal will gather evidence to show that human embryonic stem cells are capable of forming specific cell types of the embryonic human kidney. Once this is established, methods for the maintenance and directed differentiation of these cells to cell types of the mature kidney will be identified and improved. The results obtained will provide a base for future exploration of the possibility that human embryonic stem cell derived cells can be used to treat damaged kidneys.
Muscle Fusion Defects May Be A Common Cause Of Human Dystrophies

Summary
While muscle fusion is a crucial step of muscle formation, it is surprising that human muscle diseases were never associated with muscle fusion defects. We have recently undertaken a genome-wide functional screen using a mouse muscle cell line. We identified 21 genes that were previously associated with muscle dystrophies in human. The aim of this project is to examine the role of those genes during muscle fusion in vivo, using the chick embryo, mouse mutants and lines from patients as models.
Interaction Between Moz And PRC1 In Defining Epigenetic States And Gene Expression Patterns

Summary
Regulation of gene expression is implicated in all disease processes. Aberrant gene expression is particularly associated with tumour formation. In this project we determine the relationship between an oncogene MOZ and another oncogene BMI1. Together these proteins regulate one of the most important systems controlling gene expression at the level of chromatin structure.
Modulation Of Telomere Length And Subtelomeric DNA Methylation In Response To Oxidative Stress In The Male Germ Line; Implications For Tumorigenesis In The Offspring

Funding Amount
$310,684.00
Summary
This research project is designed to elucidate how the quality of a father’s spermatozoa can impact upon the health and wellbeing of his children. We hypothesize that factors, such as infertility, heavy smoking or age create a state of oxidative stress in the testes and that this stress influences the genetic structure of spermatozoa in such a way that the incidence of spontaneous mutations and susceptibility-to-cancer are significantly elevated in the offspring.
Investigating The Formation And Utility Of The Prenatal Platelet Forming System

Funding Amount
$793,442.00
Summary
A major challenge to regenerative medicine is discovering how to produce useful cell types in the laboratory. Particularly urgent is the need to generate large numbers of platelets, the building blocks of the clotting system, for clinical use. Current laboratory methods are woefully inefficient, thus cannot meet demand. This project aims to discover how platelets are made in nature. With this information we will be able to devise better platelet production strategies in the laboratory.
Redefining Proprioceptive Circuitry At A Molecular Level

Funding Amount
$564,482.00
Summary
Neurons form an extensive series of connections to relay information across the entire body. It is essential to understand how neurons know to find their way, and form the right connections, in a developing animal. This project will investigate the genes which control formation of neural circuits that are essential for correct movement.
Elucidating The Role Of MiR-196 In Formation Of The Axial Skeleton

Funding Amount
$520,087.00
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.
Nodal Signalling In Male Germ Cell Development: Balancing Fertility And Testicular Cancer Susceptibility

Funding Amount
$536,595.00
Summary
Testicular cancer is the most common type of cancer in men aged 20-40 years, and its incidence has doubled in the last 30 years. It is sometimes fetal and often results in infertility. We have discovered new genes that regulate testicular cell behaviour in the developing fetus, and here test the concept that defects in these genes might disrupt cell behaviour to the point where cancers form during adult life. Outcomes may lead to new ways to diagnose and treat testicular cancers.
Understanding The Ancestry Of De Novo Blood Formation In The Early Embryo

Funding Amount
$484,666.00
Summary
Current laboratory methods rely on a hit-or-miss approach for the production of such cells, making the prospect of producing patient-specific cells an inefficient/financially prohibitive process. This project aims to generate new knowledge into when and how fate of early blood cells in selected in nature. With this information we will be able to devise effective blood progenitor cell production strategies in the laboratory.
