| Research Abstract |
Idipathic portal hypertension (IPH) is a disease characterized by noncirrhotic portal fibrosis with unkhown etiology. To address the molecular mechanism of pathogenesis, we performed the gene analysis using Atlas cDNA Expression Arrays. Connective tissue growth factor (CTGF) was one of overexpressed genes in the liver tissue with IPH. The serum level of CTGF was significantly elevated in patients with chronic hepatitis and IPH, although there was no obvious difference among the fibrosis stages of chronic hepatitis. It was also noted that several patients with IPH showed considerably high serum levels of CTGF. Immunohistochemistry demonstrated that interstinal cells in the portal fibrosis were positively stained for CTGF. The present study suggests that CTGF might be involved in the development of portal fibrosis in IPH.
