Funded Activity Summary

Stomach cancer is the third most prevalent cancer in the Western World and result in the yearly death of several thousand people in Australia alone. We have discovered a specifice gene mutation of a receptor molecule called gp130 that results in the formation of stomach cancer in mice. We are now aiming to understand the exact molecular events by which this mutation results in the uncontrolled growth of stomach lining cells. We will employ a number of strategies to establish molecularly the extent to which this mouse model is informative for gastric cancer inhuman. In aprticular we will identify the genes that are involved in the progression of the disease. One important focus of the project is to see whether or not the moelcule (called Stat3) whose aberrant activation triggers the disease in the mouse could provide a future pharmacological target for intervention with the disease. Similarly with expertise of CIB, we will investigate with novel proteomics techniques whther we can identify a protein in the serum of these mice, which could give us aclue of whether or not the mouse ahs already developed disease. Such a protein could be of potentail diagnostic importance in the future to screen human for gastric cancer which in its eraly stages is usually without any clinical symptoms. In a related Aim we will find out the gene that can genetically cooperate with Stat3 and that is required to enable survival of newborn mice. It may well turn out mOur proposal combines the expertise of the two investigators in signal transduction and that this gene may be an important determinant to ensure that Stat3 triggers physiological rather than pathological responses in many differnet organs.
