Summary
Glaucoma is a disease of the nerve cells in the retina and optic nerve of the eye, it is the second most common cause of blindness worldwide. The risk of developing glaucoma increases exponentially with age but the mechanisms that predispose older individuals to glaucoma are not known. This study examines whether age-related changes in mitochondria, a characteristic finding in aging, results in increase susceptibility to glaucoma development.
Systems Approaches To Understanding The Assembly Of Mitochondrial Machines

Summary
Mitochondria produce the energy for our bodies. Defects in this process cause mitochondrial disease, which affects at least 1/5000 people. Diagnosis is often inconclusive as we do not understand the function of many proteins important in mitochondrial energy production. State of the art CRISPR gene-editing tools will be coupled with advanced proteomics techniques to model different types of mitochondrial disease and identify the functions of new candidate disease genes.
Functional Genomic Analyses Of Mitochondrial Disorders

Summary
Mitochondria produce most of the energy required by our bodies. Mutations in genes that make mitochondrial proteins cause mitochondrial dysfunction and lead to neurodegenerative and muscular diseases. We will identify mutations in mitochondrial genes in members of different Bulgarian and Gypsy families and discovery the mechanisms by which the mutations lead to disease.
Can Malaria Parastie Resistance To An Important Drug Spread?

Summary
Malaria is a major global health issue. Drugs are a key weapon against the disease, but resistance eventually emerges and spreads, rendering a succession of drugs useless. We have preliminary evidence that resistance to a safe and cheap drug is unable to spread. We believe drug resistant parasites die when attempting to transmit from person to person via the mosquito vector. Inability to spread resistance would make this drug extremely valuable in the fight against malaria.
Mitochondrial Enzyme Regulates RNA Metabolism In Health And Disease

$67,381.00
Summary
Mitochondria are microscopic, energy producing machines that are found in all human cells. Mitochondria contain a small set of genes that must work properly to make the energy our bodies require for health. Defects in the expression of genes coding for mitochondrial proteins causes debilitating diseases for which there are effective treatments. I will investigate how a mitochondrial protein whose dysfunction is known to cause a metabolic disease regulates mitochondrial gene expression.

Summary
Mitochondria are microscopic, energy producing machines that are found in all human cells. Mitochondria contain a small set of genes that must work properly to make the energy our bodies require for health. Defects in the expression of mitochondrial genes cause debilitating diseases for which there are currently no cures. We have developed a new set of technologies that will be applied to understand how these mutations cause disease and provide insights into possible treatments.
Regulation Of Mitochondrial Gene Expression In Disease

Summary
Mitochondria are microscopic powerplants that produce most of the energy in cells. Genes that make mitochondrial proteins must work properly to make the energy our bodies require for health. Defects in the expression of mitochondrial genes cause debilitating diseases for which there are no cures currently. A/Prof Filipovska will use new technologies to understand how these mutations cause disease and develop therapeutics for treatments of diseases caused by defects in mitochondrial genes.
The Role Of Mitochondrial Dysfunction In Metabolic Disease

Summary
We have previously found that PTCD1 can regulate mitochondrial gene expression and metabolism in cells (Mercer et al., 2011 and Lopez Sanchez et al., 2011). There is still much to learn about the mitochondria and their DNA. Charactering PTCD1, a protein that has previously seen little research, will enable us to elucidate the role of this protein in mitochondria and energy metabolism in an effort to increase understanding of obesity and type 2 diabetes.
Seizures And Carbon Dioxide – A Study Of Respiratory Acidosis As A Cause For Seizure Termination And Trial Of Carbogen As An Anti-epileptic

Summary
Although much is known about epilepsy, the reason a seizure stops is not clear. A rise in the acidity of the blood, mainly due to a rise in carbon dioxide from breathing less deeply, may well contribute. Currently the standard treatments given in hospital to stop seizures are sedatives. Although effective, this sedation can need Intensive Care treatment. We aim to develop a safe, rapid, non-sedating way to treat seizures using a small amount of carbon dioxide in oxygen.
