Summary
Liver fibrosis or scarring is a consequence of a number of diseases, leading eventually to extensive damage known as cirrhosis. It is a significant health problem both here in Australia and overseas with around 180,000 patients diagnosed each year in the Western world. Cirrhosis arises from many causes, two major groups being patients who contract hepatitis and alcoholics.

It is a significant health problem both here in Australia and overseas with around 180,000 patients diagnosed each year in the Western world. Cirrhosis arises from many causes, two major groups being patients who contract hepatitis and alcoholics. People with cirrhosis have a much increased risk of liver failure, which requires liver transplantation, or of developing liver cancer, for which current treatments have limited success. We have been studying two proteins, activin and follistatin, both of which are made in the liver. We are interested in activin because it is one of the body's mechanisms to control cell growth, and also seems to stimulate the development of scar tissue. Follistatin is the natural inhibitory substance for activin. It blocks the effects of activin and helps promote cell growth in the liver. We believe that follistatin may also be useful in controlling liver scarring. This process will be studied in animal models of cirrhosis, in the hope that follistatin treatment will reduce the level of liver damage. If successful, this would be important information that would enable us to design treatments applicable to human sufferers of these liver diseases. In another part of the project, we will assess whether activin and follistatin might be useful markers of liver disease. Most patients require a liver biopsy to assess the amount of liver damage, and a simple blood test would be a far easier, less traumatic and cheaper alternative.Read moreRead less
Novel Roles For Follistatin In Reproductive Biology

Summary
The follistatin protein has important functions throughout the body. Recent studies using mutant mice have identified key roles for follistatin in the development and function of the female reproductive system (ovary, uterus). We will now undertake detailed studies to determine how follistatin regulates these processes. This is relevant to our understanding of the mechanisms causing infection and inflammation in the reproductive tract.
