Description of Research Expertise

The Matthews laboratory is interested in the pathogenesis of various pediatric liver diseases, using zebrafish as a model organism. Specifically, we are interested in cholestatic diseases such as biliary atresia, and hepatic diseases such as non-alcoholic steatohepatitis (NASH) and other causes of liver steatosis. While NASH is certainly not limited to children, it is becoming an increasingly important disorder in pediatrics.

Several liver diseases, including biliary atresia, affect only infants, suggesting that developmental processes may be important in disease pathogenesis. Thus, a greater understanding of liver development will help us understand these disorders. We have noted that epigenetic defects are associated with biliary atresia and with abnormal biliary development, and we are very interested in understanding the contribution of the epigenome to biliary development. We have also noted an importance of multiple polarity pathways in normal biliary development and in disease pathogenesis, and we are interested in studying the role of cell polarity in biliary development and disease.

We have established several NASH models in zebrafish, and we are studying the influence of multiple pathways on the pathogenesis of NASH. In the near future, we hope to take advantage of the zebrafish system to perform small molecule screens on our NASH models, and we will perform similar studies on our cholestatic models. Such studies could uncover novel treatments for these disorders and further our understanding of pathogenesis.
