Summary
Congenital diaphragmatic hernia is a common congenital abnormality and occurs when the diaphragm fails to separate the abdominal and thoracic compartments before birth. This prevents the lung from growing properly and so at birth, the lung is unable to take over the role of gas exchange without considerable assistance. As a result, these infants are at high risk of death or significant disability and this application is focused on improving care and reducing morbidity in these infants.

Summary
Stillbirths are a global human tragedy, with 1 in 130 of all pregnancies in Australia ending in stillbirth. We propose to use ultrasound and blood markers to improve the detection of babies who are not growing well, a leading risk factor for stillbirth. Sleep position has also been associated with stillbirth, so we will study fetal heart rate responses during an overnight sleep study to see if breathing events overnight may be an important contributor to stillbirth in growth restricted fetuses.
Measuring Hypoxia Induced MRNA In Maternal Blood To Monitor Wellbeing Of Growth-restricted Fetuses

Summary
Severely growth restricted fetuses are at peril of stillbirth from low oxygenation. While ultrasound monitoring improves outcomes, babies are still lost. Better ways to monitor the health the unborn baby are needed. We have recently discovered fetuses’ starved of oxygen leak RNA into mother's blood. Thus, measuring RNA molecules in blood could be used to assess fetal health. We will examine whether measuring mRNA in maternal blood could be used to monitor wellbeing of growth-restricted fetuses.
Environmental Influences In The Establishment Of The Epigenetic Landscape In Children

Summary
The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells ....The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells use epigenetic changes to help control how they grow and develop. Evidence suggests a direct link between diet and environmental influences on our epigenetic profile. Recent research has traced the origins of many of the health problems of adult life back to the earliest periods of development _ to the time spent in the womb and the first few years of life. If we are born with a low birth weight, we are more likely to get sick later in life. Overwhelming evidence exists that the environment in the womb is critical for a healthy birth weight (and health in later life) and it is thought that epigenetics may be the missing link between this environment, low birth weight, and therefore health in later life. In addition, mounting evidence supports a general link between epigenetic de-regulation and predisposition to disease. However, the timing and the overall contribution of environmental- genetic influences to the establishment of faulty epigenetic markings remain largely unknown. Twins are the best model to study this link as they share similar (but not identical environments) and some share identical genetic makeup. Using twins, Dr Jeffrey Craig and his team will investigate the factors in the prenatal environment that modify specific cells, leading to low birth weight and increase disease risk later in life. They predict that this occurs via specific changes in gene activity caused by epigenetic disruption.Read moreRead less
Defining The Impact Of Universal Iron Interventions In Young Children: A Randomized Controlled Trial In Rural Bangladesh

Funding Amount
$2,794,373.00
Summary
Although nearly half of the world's young children are anaemic, evidence regarding the best approaches to correct this problem are limited. New data even suggests that the conventional approaches (iron supplements, multiple micronutrient powders) may even be harmful. We will perform the definitive trial which will confirm the existence and magnitude of any benefit (and harm) from these interventions in young Bangladeshi children. This trial will inform global policy on anaemia control.
Benefits And Safety Of IRon Supplementation With MAlaria Chemoprevention To Children In Malawi (IRMA) - A Randomised Controlled Trial

Summary
Anaemia and malaria frequently coexist in low income settings e.g. sub-Saharan Africa and Asia. Iron interventions aim to reduce anaemia but exacerbate malaria. We aim to test whether iron is made safe by coadministering malaria prevention, and whether these interventions improve child health outcomes especially cognitive development, while ensuring malaria resistance does not emerge.
Defining Genetic And Epigenetic Variation During Early Development

Summary
We all began life with a set of genes inherited from our parents. However, it's now known that from the time we were in the womb onwards that genes can be turned off and on by the environment or even completely lost or gained. Even what your mother ate or how she behaved while she was pregnant could have influenced your future health. Because people are so different, we are studying the subtle differences between twins to tease out the factors that may influence our genes and our health.
Stem Cell Based Strategies For Re-establishing T Cell Immunity In Aging And Disease.

Summary
The thymus is the organ responsible for producing T cells, a key cell type in the body’s immune system. Certain cancer treatments damage the thymus, compromising the immune system and leaving patients susceptible to opportunistic infections. This proposal will develop clinically applicable strategies for generating functional human thymic mini-organs that could eventually help restore the immune system of people receiving treatment for cancer.
The Role Of Copper In Ubiquitin-dependent Protein Degradation In Alzheimer's Disease

Funding Amount

Summary
Ubiquitin’s are small proteins that tag other proteins in a process known as “Ubiquitination”. Often this is to target them for degradation once they are no longer needed i.e. to take out the rubbish. This process is disrupted in Alzheimer’s disease (AD), which may contribute to the disease. This project aims to find out if copper, an essential metal for life, is required for this process. Drugs that are designed to deliver copper to brain cells have been effective in small AD clinical trials.
The Role Of Presenilin In Metal Homeostasis And Alzheimers Disease

Summary
Presenilin, a protein involved in Alzheimer’s disease (AD), may regulate copper and zinc levels. Copper and zinc are essential nutrients however a deficiency or excess can cause disease. Promising metal-altering AD drugs, are in various stages of clinical trial. I aim to characterize the interaction of Presenilin and metals using both mouse and cultured human cell models that are deficient in Presenilin. Understanding this interaction should lead to better drug design and treatment of AD.
