The Role Of Nutrition In Disease-linked Epigenetic Inheritance

Summary
This project aims to investigate one mechanism behind fetal programming, in which a suboptimal in utero environment can affect health of offspring in later life. We and others have recently shown that fetal programming can be caused by changes in the way genes behave, and we will examine how many genes are affected by these changes. We will ask whether the changes can increase in frequency with long-term exposure to nutritional stress, and become entrenched within the population.
Mapping EQTL To Dissect The Genetic Basis Of Complex Trait Variation

Summary
People vary in traits such as height and blood pressure and in their susceptibility to common disease. Part of these differences between individuals is because of their genetic make-up. This research is about understanding which of the genes are involved in common variation and how they work. In particular, the researchers investigate if variation in DNA sequence causes genes to be expressed more or less and how gene expression affects risk of disease.
Determining The Impact Of Inherited Epigenetic Information On Development And Disease

Summary
Recent observations show that the environment in which you live can alter disease susceptibility in your children, without altering the sequence of your genes. This is due to epigenetic mechanisms which control the way the DNA is interpreted. In this study we will study the potential for epigenetic mechanisms to affect sperm production and impact characteristics and disease in the next generation.
Evaluation of the optic nerve head (optic disc) is important in the diagnosis of various eye diseases, including glaucoma. The influence of genetics on the shape of the optic disc is not well understood because shape is difficult to measure. Using a novel method of shape analysis, this study will examine optic disc shape in populations of Australian twins and individuals with optic nerve disease. It will contribute to the genetic understanding of the optic nerve head and related disorders.
Molecular Basis Of Transgenerational Epigenetic Inheritance In Mammals

Summary
While it has long been recognised that it is not just DNA, but chromosomes, that are passed from the gametes to the embryo, the non-DNA component was thought to carry no information with respect to the offspring's ultimate phenotype. However, there is now evidence that the non-DNA component, the epigenetic component, can play a role in the inheritance of phenotype in mammals. This study will attempt to determine the molecular nature of this phenomenon.
Defining The Epigenetic Origins Of Maternally Inherited Disease.

Funding Amount
$731,162.00
Summary
Epigenetic (non genetic) changes to the DNA in sperm and eggs can alter outcomes in children. Despite the potential for drugs and diet to mediate some of these inherited effects, the processes involved are very poorly understood. By determining the mechanisms that regulate epigenetic inheritance, this project will improve our understanding of how epigenetic mechanisms acting in the parent, can mediate inherited disease and life-long health outcomes in our children.
Determining The Impacts Of Epigenetic Modifying Drugs On Germline Programming And Offspring Health
Funder
National Health and Medical Research Council
Funding Amount
$863,918.00
Summary
New drugs have been developed that inhibit specific enzymes that regulate epigenetic pathways in cells. These pathways significantly affect growth and development in offspring and may represent a risk to future children of patients taking the drug. This project will determine these risks and provide data for developing clinical guidelines for safe use of the drugs.
Blood Biomarkers For The Diagnosis Of Pre-clinical Alzheimer’s Disease Employing The Dominantly Inherited Alzheimer Network Cohort

Funding Amount
$1,125,804.00
Summary
Alzheimer’s disease (AD) is the most common form of dementia and yet a postmortem examination serves as the only definitive diagnosis. The current proposal seeks to investigate alterations in biochemical profiles of individuals who will develop Alzheimer’s disease due to an inherited mutation, against family members who are non-carriers of the mutation, to identify AD related blood changes which can contribute towards the development of a diagnostic blood test for the disease.
