Abstract
Liver fibrosis is a common pathological process of chronic hepatic injury, preceded by the chronic inflammation. The homeobox B13 (HOXB13) gene, a member of HOX family, plays diverse biological roles in embryonic development, carcinogenesis, and many inflammatory diseases. However, the expression of HOXB13 in chronic liver diseases including hepatic fibrosis remains to be defined. In present study, 55 patients with hepatic fibrosis, 15 patients of hepatocellular carcinoma, and 17 healthy controls were enrolled in this study. Pathological specimens were collected through liver biopsy or surgical resection. The degree of hepatic inflammation (G0–G4) and fibrosis (S0–S4) of hepatic fibrosis was scored based on the modified histology activity index. Intrahepatic HOXB13 expression was analyzed using immunohistochemistry analysis. Compared with healthy subjects, both patients with hepatic fibrosis and patients with hepatocellular carcinoma exhibited significant accumulations of HOXB13+ cells in the liver (p < 0.05). Additionally, the number of HOXB13+ cell was significantly elevated along with the increment of hepatic inflammatory activities, but not fibrosis stages, among these liver fibrosis samples (p < 0.01). Furthermore, the quantity of HOXB13+ cells were also positively correlated with hepatic enzymes, alanine transaminase (r = 0.299, p = 0.041) and aspartate aminotransferase (r = 0.317, p = 0.013) in our cohort of hepatic fibrosis. In conclusion, our study identified a strong hepatic expression of HOXB13 among patients with hepatic fibrosis, which strongly associated with the degree of hepatic inflammatory activity for patients with hepatic fibrosis, suggesting an important role of HOXB13 during the pathogenesis of liver fibrogenesis.
