We investigated the gene expression of tissue inhibitor metalloproteinases (TIMPs) and matrix metalloproteinases (MMPs) and serum levels of TIMPs, MMPs, and hyaluronic acid that are associated with liver fibrosis in 64 patients with nonalcoholic fatty liver diseases (NAFLD). Whereas, no differences were found between patients with and without nonalcoholic steatohepatitis (NASH) in serum levels of hyaluronic acid when excluding NASH patients with advanced fibrosis, the quantity of MMP2 mRNA in liver tissue and serum MMP2 levels were significantly higher in patients with NASH than those without, even focusing on patients with less advanced fibrosis, indicating the initiation of liver fibrosis.
