In this study, we found that the expressions of both β-actin mRNA and protein increased significantly with hepatic fibrosis formation after 6 weeks infection with Schistosoma japonicum and kept high level during the progression of hepatic fibrosis, while the levels of β-Tubulin and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) remained stable. The gene discussed is ACTB; the disease is Hepatic fibrosis.
