abstractText | Periostin actively contributes to tissue injury, fibrosis, atherosclerosis, and inflammatory diseases; however, its role in hepatic fibrosis is unclear. Herein, we revealed that periostin expression was significantly up-regulated in carbon tetrachloride- and bile duct ligation-induced mice with acute and chronic liver fibrosis. Deficiency in periostin abrogated the development of liver fibrosis in mice. Carbon tetrachloride treatment significantly increased alpha-smooth muscle actin, fibronectin, and collagen I levels in wild-type mice, which were unaffected in periostin-knockout mice. Periostin-deficient mice showed a significantly reduced area of collagen deposition and decreased levels of serum alanine aminotransferase and aspartate aminotransferase compared with wild-type mice after 2 weeks of carbon tetrachloride administration. Chemokine ligand 2, IL-6, IL-1beta, tumor necrosis factor-alpha, and tissue inhibitor of metalloproteinases 1 mRNA levels were significantly lower in periostin-deficient mice than in wild-type mice after carbon tetrachloride treatment. Periostin colocalized with hepatic stellate cell-derived collagen I and alpha-smooth muscle actin in mouse acute and chronic fibrotic liver tissues. Transforming growth factor (TGF)-beta1 markedly induced periostin expression in primary mouse hepatic stellate cells. Periostin-deficient mice showed significantly lower levels of TGF-beta1 and TGF-beta2 compared with wild-type mice after carbon tetrachloride treatment. High levels of periostin in patients with acute or chronic hepatitis correlated with TGF-beta1 and TGF-beta2 expression in serum from patients with hepatitis. Data indicate that periostin is a novel mediator of hepatic fibrosis development. |
