Summary
This study will use a unique population isolate from Norfolk Island. We aim to identify genes that play a role in cardiovascular disease risk. Norfolk has a population of ~1200 permanent residents, most of whom are direct descendents of 18th century English Bounty mutineers and Polynesian women. We will undertake gene expression mapping to identify genomic loci that influence cardiovascular disease using samples from this population isolate.

Breast cancer affects approximately one in ten women and is therefore a major health problem. In order to improve the diagnosis, treatment and prognosis of this disease, it is critical to understand the molecular defects that contribute to disease initiation and progression.

In order to improve the diagnosis, treatment and prognosis of this disease, it is critical to understand the molecular defects that contribute to disease initiation and progression. Over the last twenty years significant progress has been made in this regard, however there still remain a considerable number of unanswered questions. For example, it is not yet clear precisely what contribution each of these genes makes. This is largely due to limitations in current mutation detection strategies and an incomplete understanding of all of the genetic elements for which disruption can lead to loss of gene function. This propsal aims to identify all of the genetic elements critical for the expression of an important breast cancer gene called BRCA1. Furthermore, it aims to determine the status of these elements in breast cancer patients, thus expanding our knowledge of the actual contribution disruption of this gene makes to this disease.Read moreRead less
Comprehensive transcriptional mapping of emergent division-linked cell fate decisions. This project proposal will lead to a better understanding of the molecular mechanics that drive certain cellular behaviors. To do this, we will use a frontier technology, RNA sequencing, which we think has the potential to revolutionise Australian science and make Australia an even more attractive place for young researchers.

To do this, we will use a frontier technology, RNA sequencing, which we think has the potential to revolutionise Australian science and make Australia an even more attractive place for young researchers. The community at large benefits from novel technologies as they create new opportunities for university research and attract young minds to the challenges of maths and science.Read moreRead less
Genomic Characterisation Of Asbestos Related Lung Cancer

Summary
Lung cancer causes more deaths in Australia than any other cancer. Smoking is the main cause, but people exposed to asbestos are also at risk, and it can be difficult to know whether a case is due to tobacco, asbestos or both. We will study lung cancer genes in people with asbestos exposure to find whether asbestos lung cancer has a specific pattern of abnormal genes (signature). If so, this could help people entitled to compensation, and also point to new treatments for asbestos lung cancer
Retrotransposon Regulation Of The Human Innate Immune Response

Summary
Complete sequencing of the human genome has revealed the positions of approximately 20,000 genes. In addition, nearly 50% of the human genome is comprised of repetitive sequences previously thought of as junk DNA. Numerous studies are now finding that this DNA actually has a variety of important functions, particularly in the control of gene activity. This project will examine the relationships between gene expression and nearby repetitive sequences during the innate immune response in humans.

Summary
Sickle cell anemia and thalassemia are the commonest genetic disorders worldwide. Those affected suffer devastating clinical sequelae and mortality in the first twenty years of life remains high. A cure for these diseases is dependent on the replacement of the affected or absent hemoglobin protein chains with normally functioning hemoglobins. This is evident in rare patients who co-inherit a natural mutation which elevates fetal hemoglobin (HbF), as these patients have a dramatically ameliorated ....Sickle cell anemia and thalassemia are the commonest genetic disorders worldwide. Those affected suffer devastating clinical sequelae and mortality in the first twenty years of life remains high. A cure for these diseases is dependent on the replacement of the affected or absent hemoglobin protein chains with normally functioning hemoglobins. This is evident in rare patients who co-inherit a natural mutation which elevates fetal hemoglobin (HbF), as these patients have a dramatically ameliorated clinical course. Therefore, treatment strategies which could reactivate fetal globin gene expression after birth should be explored for these diseases. To achieve this goal we must further our understanding of the normal mechanisms of developmental regulation of globin gene expression. To this end we have recently identified a novel gene which is critical for fetal globin expression. The studies we propose here will further define the function of this gene and assess its potential for gene therapy for sickle cell disease and thalassemia.Read moreRead less

Skin cancer has a high incidence in the Australian population. Schizophrenia is a psychiatric disorder that affects a significant proportion of the population worldwide. Both illnesses have genetic roots and can be triggered by environmental factors. We will uncover genetic relationship to disease and their responses to environmental conditions using computational methods and mathematical algorithms that can aid in the determination of function, especially in disease states. Understanding the complex genetic interactions that trigger these illnesses would give great benefits in preventive health care, skin cancer and schizophrenia genetic basis, and may lay the ground for building new methods for "personalized medicine".

A Structural And Functional Basis For The Regulation Of Gene Expression By Nuclear Retention Of RNA

Funding Amount

Summary
The nuclear retention mechanism is a novel way used by cells to control which genes are made into proteins - a fundamental process for all diseases, particularly cancers. This project will employ cutting edge structural and proteomic techniques to determine the molecular details underpinning nuclear retention. These insights will be important for the development of new tissue-restricted gene therapy applications and drugs targeting the cancers that rely on this mechanism.
