Summary
3 million children die every year from malaria infections. A leading vaccine candidate is a protein from the malaria parasite called AMA1. Humans that have been infected with malaria make antibodies to this protein which can kill parasites, however little is known about how this occurs. We aim to identify regions of the protein that generate antibodies that prevent malaria parasites from invading human cells and help in the search for a vaccine against malaria.
Identification Of Schizophrenia Susceptibility Genes: A Collaborative Project With The University Of Indonesia

Summary
Schizophrenia is present in all populations at a similar incidence. The project aims to identify genetic risk factors in three genomic regions previously detected by us in a genome-scan for genetic linkage in 152 Indonesian families. Colleagues at the University of Indonesia will collect an additional sample of 2000 individuals for replication. This sample will be available for research in Australia. Knowledge of risk factors will aid in diagnosis, prevention, and development of novel therapies.

Summary
Bowel cancer is a major health burden. Surgical resection of the primary cancer is often possible at diagnosis, yet in many patients the cancer will recur. Together with mutations, inherited genetic variants influence the rate of bowel cancer growth. This study aims to identify inherited variants predictive of cancer recurrence. Improved prediction of recurrence will permit more targeted use of clinical interventions, tailored to the individual patient, ultimately improving patient survival.

Summary
The prion diseases are a group of transmissible, neurodegenerative disorders affecting both humans and animals. The most common form in humans is sporadic Creutzfeldt-Jakob disease (CJD), although acquired (variant CJD) and inherited (familial CJD) forms also exist. Prion diseases are transmissible by inoculation with, or dietary exposure to, infected tissues. The infectious agent, referred to as a prion , has not been conclusively identified.

The most common form in humans is sporadic Creutzfeldt-Jakob disease (CJD), although acquired (variant CJD) and inherited (familial CJD) forms also exist. Prion diseases are transmissible by inoculation with, or dietary exposure to, infected tissues. The infectious agent, referred to as a prion , has not been conclusively identified. However, a major component of purified prions is an abnormal disease associated form of the host prion protein. Differences in the duration of illness and pathology of sporadic CJD suggests that the disease may be caused by different prion strains. The existence of different prion strains may explain the limited clinical success of anti-prion therapeutics modeled in rodent models of prion diseases. In this study a cell-free model of prion propagation will be used to investigate the basis of human prion strains. This assay will also be used to identify and determine whether the therapeutic efficacy of anti-prion compounds is influenced by human prion strain type. This study will represent the first host species and prion strain specific screen of anti-prion therapeutics aimed at developing the best possible model for the identification and development of therapeutics for human prion diseases.Read moreRead less

Summary
How we handle chemicals that enter our bodies depends on a series of enzymes that are responsible for breaking down the chemicals and eliminating them. The activity of many of these enzymes varies between individuals so our responses to chemicals and drugs is different for each individual. Some of the enzymes vary because of inherited mutations, but others vary because of the diets we eat and the environment in which we live. This project will investigate a major enzyme called acetlytransferase ....How we handle chemicals that enter our bodies depends on a series of enzymes that are responsible for breaking down the chemicals and eliminating them. The activity of many of these enzymes varies between individuals so our responses to chemicals and drugs is different for each individual. Some of the enzymes vary because of inherited mutations, but others vary because of the diets we eat and the environment in which we live. This project will investigate a major enzyme called acetlytransferase that has been implicated as a risk factor in diseases such as cancer, asthma, liver cirrhossis and adverse drug reactions. We plan to look at the enzyme in cells and determine what environmental factors contribute to its variation between individuals, and how this impacts on the genetic mutations that have been found in its gene. From these studies, we will have a much better undersanding of how different people metabolise foreign chemicals, and should be able to predict those most at risk of certain diseases.Read moreRead less
Use Of Expression Profiling To Identify Genes Influencing Cardiovascular Risk In The Norfolk Island Population Isolate

Funding Amount

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.
