Summary
In most countries, acute lymphoblastic leukaemia is the commonest cancer in children. One in 2000 children will develop this disease before their 15th birthday. New methods of treatment introduced over the last 30 years have resulted in cure for many children. However, one third of children diagnosed with this type of leukaemia still die and, even in those whose lives are saved, cure is achieved at a significant cost to the child, the family and the community.

One in 2000 children will develop this disease before their 15th birthday. New methods of treatment introduced over the last 30 years have resulted in cure for many children. However, one third of children diagnosed with this type of leukaemia still die and, even in those whose lives are saved, cure is achieved at a significant cost to the child, the family and the community. Greater understanding of the development of childhood leukaemia may lead to preventive measures. Most children with this type of leukaemia are very young, suggesting that factors to which parents are exposed may affect future children. For this reason, as well as investigating the health and lifestyle of the child, it is essential to study the parents. Recent research suggests an association between the mother's intake of folate during pregnancy and her child's risk of developing the most common type of childhood leukaemia. It is also apparent that genetic differences result in varying abilities to deal with toxins, which may alter the risk of developing some cancers. Diet and lifestyle probably also affect this risk. These observations and interactions need to be examined in greater detail. In this large Australia-wide study specific genes will, for the first time, be examined and analysed in conjunction with rigorous assessment of exposures thought to be related to the development of childhood leukaemia. Results obtained from children with leukaemia and their parents will be compared with those from healthy children and their parents. This study is unique in its attempt to assess gene-environment interactions in Australian children and their parents. It will clarify the role of folate and other potential environmental agents in the development of childhood leukaemia and examine gene variations that may affect cancer risk.Read moreRead less
An Investigation Into The Molecular Basis Of MAIT Cell Recognition Of Vitamin B Based Metabolites

Summary
Mucosal associated invariant T cells (MAIT cells) are an abundant T-cell population in humans, that is found mostly in the gastrointestinal mucosa. We have recently shown that MAIT cells can be activated by metabolites of vitamin B. This proposal will investigate how the MAIT cells "see" vitamin B metabolites. This research will pave the way for novel therapeutics that can modulate MAIT cell activity.
A Randomised Controlled Trial Of High Dose Folic Acid To Slow The Progression Of Atheroma In Renal Failure (194246)

Summary
The Atherosclerosis and Folic Acid Supplementation Trial (ASFAST) is examining the effect of high dose folic acid supplementation on the development of desease of the heart and blood vessels in people with kidney failure. Subjects in the study take 15mg folic acid daily or a dummy tablet for 3 to 5 years. Folic acid is known to reduce the levels of a substance called homocysteine which is elevated in people with kidney disease.

Subjects in the study take 15mg folic acid daily or a dummy tablet for 3 to 5 years. Folic acid is known to reduce the levels of a substance called homocysteine which is elevated in people with kidney disease. Homocysteine has been associated with disease of the heart and blood vessels and these diseases occur very commonly in people who also have kidney failure. I t is hoped that by using folic acid to reduce the levels of homocysteine, we can reduced the amounbt of heart and blood vessel disease in people with kidney failure.Read moreRead less

Summary
Stroke is one of the most important causes of death and long-term disability in developed countries. Hardening of the arteries (atherosclerosis) is the major cause of stroke and heart attacks. High blood pressure, high blood concentrations of cholesterol, cigarette smoking and diabetes accelerate the formation of atherosclerosis, but they do not account for all strokes and heart attacks caused by atherosclerosis.

Hardening of the arteries (atherosclerosis) is the major cause of stroke and heart attacks. High blood pressure, high blood concentrations of cholesterol, cigarette smoking and diabetes accelerate the formation of atherosclerosis, but they do not account for all strokes and heart attacks caused by atherosclerosis. There is now increasing evidence that high blood concentrations of homocysteine, a normal protein in the blood, are another major causal risk factor for atherosclerosis (and stroke and heart attacks). Furthermore, blood concentrations of homocysteine can be lowered by about one quarter with simple, safe and inexpensive multivitamin therapy (folic acid, vitamin B12, and vitamin B6). However, despite the potentially massive public health benefits of such a strategy, it remains to be demonstrated in properly designed clinical trials that lowering homocysteine levels in the blood actually prevents stroke and heart attack. The VITATOPS trial is the only ongoing randomised, double-blind, placebo-controlled trial in the world which aims to determine whether multivitamin therapy (folic acid 2 mg, vitamin B12 0.5 mg, and vitamin B6 25 mg) prevents recurrent stroke and heart attacks in patients who have suffered a recent stroke.Read moreRead less

Summary
We are investigating how mothers may have health difficulties during pregnancy, such as high blood pressure, and how this can affect their fetuses' health. There is emerging evidence that an unhealthy placenta during pregnancy can greatly affect fetal development, and it seems that inflammation in the placenta during pregnancy may be a key factor in reducing fetal growth, resulting in low birth weight infants. Our studies are aimed at developing new treatments for this.
Epigenetic Programming Of Immune Development In Utero: Role Of The Maternal Environment In The Allergy Epidemic

Summary
This study will provide new insights into the development of allergic disease. Specifically, we will explore the hypothesis that allergic disease and other disorders or immune dysregulation occur as a result of gene-environmental interactions in early life, and that these events begin in pregnancy when the developing fetus is still developing and most susceptible to these effects.
