Summary
Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer. Several of these regions do not contain any known protein coding genes, suggesting that non-protein coding genes could be responsible for the associated risk.

Summary
Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer. The aim of this proposal is to identify and characterise these non-coding genes that are modulate breast cancer risk. Understanding how sequences variations that alter these novel genes contribute to breast cancer will provide novel avenues for therapy.
We have identified genetic abnormalities in 5% of breast cancers that fall in a novel DNA element called BIME1. This proposal aims to determine whether these genetic abnormalities contribute to breast tumourigenesis and which genes and pathways are affected by these mutations. The outcomes of this proposal may lead to the development of novel therapies for breast cancer or could influence the choice of existing therapies for patients that harbour these genetic abnormalities.

Summary
Assessing a woman’s breast cancer risk by profiling polygenic risk represents a new approach in the familial cancer setting. My study is part of a program of research that aims to facilitate translation of polygenic risk information into clinical practice. For this, I will invite 400 women to receive their personal polygenic result and i) assess interest in receiving this result; ii) assess psychological and behavioural outcomes of receiving or not receiving their personal polygenic risk result

Summary
A key step in the development of most cancers is the switching on of an enzyme, telomerase, that allows cancer cells to keep growing without limit. We will study the molecular details of this step using new techniques for functional analyses of the genome in human breast cells grown in the laboratory. Blocking telomerase has great potential for cancer treatment, so analysing how this enzyme gets switched on may identify new strategies for achieving this for breast cancer - and other cancers.

Summary
Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer. Several of these regions do not contain any known genes, suggesting that regulatory DNA sequences are responsible for the associated risk. The aim of this proposal is to identify and characterise these DNA sequences. Understanding how sequences variations in these regions contribute to breast cancer will provide novel avenues for therapy.

Summary
Recent studies have identified DNA markers within the human genome that are associated with an increased risk of breast cancer. Most of these markers are located in noncoding regions, therefore the key genes driving risk are not known. This proposal will identify the target genes at all breast cancer risk regions and assess how specific markers affect disease risk. Understanding how DNA variation contributes to breast cancer will provide new avenues for prevention or treatment.

This project focuses on what and how primary school teachers learn about improving classroom practices from co-inquiry interventions. The effective diagnosis of student learning difficulties and the design of educational interventions based on such diagnosis is a core component of quality teaching. Yet many teachers have not acquired the knowledge and skills to undertake such learning diagnostic and design work. The project plans to engage practitioners in co-inquiry through collaborative analysis of professional learning conversations and classroom practices across disadvantaged public schools in urban and regional locations across Queensland. It aims to examine the sustainability of co-inquiry models to improve student learning.Read moreRead less

Summary
Anomalies of the face and limbs are amongst the most common features of human birth defects, and their frequent association suggests that the same genes are involved in governing the development of the limbs and face during embryogenesis. We have used a genomics-based approach to identify genes involved in limb development based on their alteration in a mouse model which develops extra fingers and toes. Defects in this mouse result from changes in Gli3, a gene which is known to be important in b ....Anomalies of the face and limbs are amongst the most common features of human birth defects, and their frequent association suggests that the same genes are involved in governing the development of the limbs and face during embryogenesis. We have used a genomics-based approach to identify genes involved in limb development based on their alteration in a mouse model which develops extra fingers and toes. Defects in this mouse result from changes in Gli3, a gene which is known to be important in both limb and face development. Based on the organs in which our genes of interest are active, we believe that they will also play key roles in embryonic development of the limbs, face and other organs. We now plan to investigate the regulation of a subset of these genes based on analysis in mouse models of limb and face development. In addition, we have chosen to further analyse the function of a completely novel gene we have identified which our preliminary studies suggest may play a role in the normal development of the lip and palate. These studies have the potential to shed light on the processes governing how organs develop, as well as on the molecular basis of common birth defects such as polydactyly (extra fingers and toes) and cleft palate.Read moreRead less

Summary
The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D.

Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain cells perform specialised functions. In test-tube experiments, IGFBP-3 and IGFBP-5 interact directly with the receptors that regulate the effects of these hormones. If the same thing happens inside the cell, IGFBP-3 and IGFBP-5 could change the way these receptors respond to signals from outside the cell. We will investigate what effect these IGFBPs have in living cells and in whole animals and how this may relate to human disease. If we are able to understand how IGFBP-3 and IGFBP-5 affect the way cells respond to vitamin A and D, then we may be able to develop new ways to treat certain human diseases.Read moreRead less
