Summary
The S100A1 protein is one of the most abundant proteins in human heart muscle cells. It binds calcium ions and may play a role in the regulation of heart function. S100A1 levels are reduced in human heart failure, but it is unclear whether this reduction contributes to worsening of the disease. To study this, we have generated a genetically modified mouse strain that cannot make the S100A1 protein. We will use these mice to study how important the protein is for heart function under normal condi ....The S100A1 protein is one of the most abundant proteins in human heart muscle cells.

To study this, we have generated a genetically modified mouse strain that cannot make the S100A1 protein. We will use these mice to study how important the protein is for heart function under normal conditions, and how it contributes to the development of heart failure. Preliminary data indicate that adult mice with reduced S100A1 protein levels develop a form of heart disease that significantly reduces the efficiency of the pump function of the heart.Read moreRead less

Summary
Emphysema is a major component of Chronic Obstructive Pulmonary Disease (COPD), the fifth leading cause of death in Australia for which there is no effective treatment. We have discovered a specific mutation in a gene called gp130 that results in the formation of emphysema in mice. This finding allows us to understand the exact mechanisms by which this mutation causes emphysema, and therefore has the potential to uncover new strategies to design novel therapies against emphysema in humans.

Summary
Stomach cancer is the second most common cause of cancer-related deaths worldwide, and results in the yearly death of several thousand people in Australia alone. We have discovered a specific mutation in a gene called gp130 that results in the formation of gastritis and stomach cancer in mice. We are now aiming to understand the exact molecular events by which this mutation results in chronic inflammation and the subsequent uncontrolled growth of epithelial cells that line the stomach wall.
