The authors identified BMP-2 downregulation in human and experimental fibrotic livers, and found that adenovirus-mediated BMP-2 gene delivery ameliorates liver fibrosis and biliary injury in mice. Mechanistically, BMP-2 suppresses proliferation and migration of hepatic stellate cells by antagonizing TGF-β signaling and epithelial-to-mesenchymal transition. BMP-2 may therefore constitute a therapeutic target for liver fibrosis treatment.
