Summary
Asthma is a major health problem in Australia affecting over 10% of the population at any time, and more than 25% of the population at one stage in their lives. Although the public perception is that asthma treatments have improved management of the disease, more than 700 people die from severe asthma each year and hospitalisation from exacerbation (sudden worsening) is one of the most costly components of the health care burden in Australia and most developed countries.

Although the public perception is that asthma treatments have improved management of the disease, more than 700 people die from severe asthma each year and hospitalisation from exacerbation (sudden worsening) is one of the most costly components of the health care burden in Australia and most developed countries. Currently there are no molecular markers that can predict who will get severe asthma and there are no specific treatments to reverse severe exacerbations. This project will use advanced molecular biology methods to examine whether a molecule called Lyn may be important. The Lyn tyrosine kinase is a member of a family of genes that participate in transmitting information across the cell membrane. This enzyme is expressed in blood cells, and is involved in mechanisms pertaining to infection, immunity and allergic responses. To further our understanding of the role of this enzyme in the context of the whole animal, we have generated mice that are unable to make Lyn protein (Lyn-deficient mice). In animal models of asthma we know that if Lyn is not functioning, severe and persistent asthma develops. We have also made preliminary studies that suggest that Lyn does not work properly in people who have been admitted to the emergency ward with life threatenting asthma. In this study we will examine in detail the role that Lyn plays in asthma and allergy, and we intend to identify the pathways that give rise to asthma in Lyn-deficient mice. We will also investigate our hypothesis that Lyn activity may be reduced or disregulated in patients with asthma and allergy. This research should lead to better predictive markers for severe asthma and also to improved and specific treatments.Read moreRead less

Summary
Obstructive Sleep Apnea (OSA) is a disorder associated with snoring. It affects 4% of adult men and causes excessive daytime sleepiness leading to increased accidents, high blood pressure and premature cardiovascular disease eg. heart attacks and strokes. Patients with OSA obstruct the floppy portion of the upper airway (UA) during sleep and consequently experience frequent episodes of oxygen deprivation as well as sleep fragmentation.

It affects 4% of adult men and causes excessive daytime sleepiness leading to increased accidents, high blood pressure and premature cardiovascular disease eg. heart attacks and strokes. Patients with OSA obstruct the floppy portion of the upper airway (UA) during sleep and consequently experience frequent episodes of oxygen deprivation as well as sleep fragmentation. OSA is at least 2-3 times more common in men than women. While OSA patients seem, on average, to have smaller upper airways than normal subjects, the cause of OSA cannot be attributed to this factor alone. For example, a small UA cannot explain the male tendency for OSA. Abnormalities in breathing control or the control of upper airway muscles that normally hold the airway open might also be important in OSA. Men have previously been shown to have a greater increase in UA resistance during sleep than women, consistent with the idea that a gender difference in UA muscle control partly explains why more men than women have OSA. We aim to investigate how changes in breathing and UA dilator muscle control might lead to unstable patterns of breathing and to OSA. We propose that protective UA muscle reflexes are reduced during sleep more in men than women, and are reduced by low blood oxygen levels and alcohol (a known aggravator of sleep apnea). We further propose that low blood oxygen levels not only result from OSA but may also aggravate OSA by preferentially reducing the activity of UA dilating muscles, by making breathing patterns overall less stable and by depressing the ability of subjects to arouse from sleep to an airway blockage. We believe that this tendency to decrease UA activity may be exaggerated in OSA patients. We also propose that men are more vulnerable to the deleterious effects of low oxygen than women. We will also examine if men and snorers have exaggerated breathing responses on arousal from sleep.Read moreRead less

It is expected to cost communities hundreds of billions of dollars in compensation. This disease is usually already quite advanced by the time a patients presents to a doctor with symptoms so we have been working on methods of early detection. This project studies a new, exciting method of diagnosis using blood levels of a molecule called 'SMRP'. Late last year we published a paper in the prestigious journal Lancet showing that SMRP was a good test to help diagnose mesothelioma and this became a lead news item around the world because of widespread concern about this disease. In those studies we found strong clues that this test was very sensitive and could detect mesothelioma a year or so before a patient develops symptoms. In this grant we will evaluate whether this test could be useful for screening asbestos-exposed individuals for early detection of this cancer. We will also study ways of improving the test using laboratory methods. This would provide a foundation for studies aimed at determining if early treatment could improve patient survival.Read moreRead less

OSA is characterized by repetitive obstructions of the floppy portion of the throat during sleep with adverse effects on oxygen levels and sleep quality. OSA is strongly associated with obesity and is 2-3 times more common in men than women. How obesity and male gender predispose to OSA is not known. We will investigate two factors that we believe are most likely involved in causing and explaining this gender difference in OSA. We will examine if breathing responses with brief awakening are sufficient to promote OSA patterns of breathing in snorers and if they are greater in male than female OSA patients. We have already shown that healthy men have greater breathing response to arousal compared to women. These brief arousals occur hundreds of times a night in OSA patients, and over-breathing on arousal may increase the probability of upper airway obstruction on falling back to sleep. We will also investigate why even healthy men show greater breathing responses compared to women. Men tend to accumulate fat centrally, particularly in the abdomen, whereas in women fat tends to be distributed more to the hips and thighs. This could be very important in OSA because downward pull exerted on the upper airway by the diaphragm is likely to be reduced in people with more abdominal obesity. This mechanisms has not yet been studied in humans. We will therefore investigate if increased forces placed on the diaphragm during sleep make the upper airway more prone to collapse. We will also investigate these effects during sleep onset, when there may well be important changes in diaphragm position as muscles relax.Read moreRead less

Summary
COPD is a leading cause of death. Smoking is the major cause of COPD and many sufferers are left with permanent damage and need ongoing treatment even after smoking cessation. Current treatments for COPD generally have limited efficacy. The project will identify the reason for the large number of dying cells and defective clearance of these cells that we have identified in the airways in COPD and study novel treatments that we hope will improve the health and well being of those with COPD.

Current treatments can only limit the gradually-increasing lung disease and is costly. Our new gene therapy technique introduces a correcting gene into affected airway cells, and it has already worked in the first tests in mice bred with CF. Airways in mice are used to test whether the effect is reliable, effective, and lasts long enough to be useful. The gene is introduced into the airway using special virus delivery-particles, after conditioning the airway to make it receptive to the particles. The method works in normal mice and in CF mice; it gives long lasting gene transfer from a single dose and seems to affect all airway cell types. The gene transfer may also be occurring in airway stem cells, i.e. the mother cells from which grow all the cells of the airway surface. Until now, no-one else has been able to produce prolonged gene transfer in this way, nor arrange gene transfer into stem cells in live airways. There are now a number of things that we must investigate before we could conduct safety and effectiveness trials in larger animals, or consider moving into clinical trials in humans. We need to understand exactly how our conditioning agent works and is it safe; measure how long the gene correction can last actually in our animals; decide if we can we re-dose animals (if needed) without losing effectiveness because of inflammation or immune responses that might occur; and decide how important the airway stem cells are in producing the length of the gene transfer. Because it has been difficult to measure gene correction in CF airways, we will also test new ways we have developed to measure how well the gene correction works in CF airways. The findings of this project will allow us to develop our method to where we can test it in larger animals, to provide a strong, long-lasting gene correction that will be safe for testing in human clinical trials.Read moreRead less
