Summary
Iron loading disorders (such as thalassaemia) represent an important class of human disease. As part of the treatment for these diseases, the iron needs to be removed and this is often done using iron-binding drugs known as iron chelators. Current chelators are not ideal due to side effects or onerous delivery methods. The goal of this project is to use nanotechnology to develop more effective ways of delivering chelators to improve their effectiveness and reduce toxicity.

Summary
Friedreich's ataxia (FA) is a neuro- & cardio-degenerative disease where there is an accumulation of toxic iron (Fe) in the mitochondrion. Work from our current NHMRC grant showed iron plays a significant role in FA pathology In fact, the CIs dissected the mechanisms of mitochondrial iron-loading & have published 8 papers in high impact journals with 3 papers in PNAS USA in the last 2 yrs Understanding of this process has led to the design of rationalised drugs for FA This work in this Renewal c ....Friedreich's ataxia (FA) is a neuro- & cardio-degenerative disease where there is an accumulation of toxic iron (Fe) in the mitochondrion.

Beige fat is a recently described kind of fat which instead of storing fat and contributing to obesity burns energy and burns glucose. It helps to combat obesity and diabetes. If it could be increased and switched on, it would help to treat obesity and diabetes. This grant will study a new pathway to try to increase the amount of beige fat and to increase its activity.

Summary
Iron is crucial for many essential biological processes. Recently, we demonstrated that iron-depletion can affects important signalling pathways (e.g., JNK and p38) that play important roles in growth arrest and apoptosis. This study is designed to investigate the cellular and molecular effects of iron depletion which currently remains unclear. The research is crucial for understanding: (1) the effects of iron deficiency and (2) for understanding the effects of iron chelators that are used for t ....Iron is crucial for many essential biological processes.

Summary
The impaired coordination and tremors experienced by the 64,000 Australians with Parkinson’s disease make managing life at work and home difficult. With 240,000 Australians projected to be living with Parkinson’s disease by 2033, the discovery of agents that slow or stop disease progression is urgent. Iron in the brain has been implicated in Parkinson’s disease. In this project, the performance of new low toxicity agents in altering brain iron distribution will be studied as potential drugs for ....The impaired coordination and tremors experienced by the 64,000 Australians with Parkinson’s disease make managing life at work and home difficult.

The lung in people with the genetic disorder cystic fibrosis (CF) contains increase amounts of iron, which promotes bacterial infection. In this research project we are using mouse models of CF and airway cells obtained from people with CF to investigate the underlying mechanism of abnormal iron regulation. We are also examining the therapeutic potential of compounds that interfere with the ability of bacteria to obtain iron to see whether this can overcome antibiotic resistance.
