<qa>  What is the relationship between the levels of these proteins in muscle and liver and the degree of2. To use liver and muscle biopsies to characterize the changes in abundance of mRNAs and proteins that characterize inflammation, extracellular matrix remodeling, and fibrosis. The investigators will use quantitative rt-PCR and immunoblot analysis to compare mRNA expression and protein abundance of collagens I and III, fibronectin, and connective tissue growth factor CTGF to test the hypothesis that there is a direct relationship between the levels of these proteins in muscle and liver and the degree of fibrosis.
