To test this hypothesis, we induced fibrosis in rats by twice weekly injections of carbon tetrachloride (CCl (4)) and Smad2 phosphorylation was measured by immunohistochemical method; protein expression in myofibroblasts (MFBs) induced by TGF-beta1 was analyzed by western blotting and plasminogen activator inhibitor type 1 (PAI-1) transcriptional activity in MFBs was evaluated.

Background & Aims: Plasminogen activator inhibitor-1 (PAI-1) is an acute phase protein that has been shown to play a role in experimental fibrosis caused by bile duct ligation (BDL) in mice.
However, its role in more severe models of hepatic fibrosis (e.g., carbon tetrachloride; CCl (4)) has not been determined and is important for extrapolation to human disease.

Gastroenterology. 2008 Apr;134(4):1180-90. Epub 2008 Jan 11.

Transfection of cells with galectin-7 small interfering RNA inhibited nuclear export of Smad3 and abolished suppressive effect of HGF on expression of TGF-beta-responsive genes such as COL1A2 and plasminogen activator inhibitor-1.
RESULTS: Over expression of HGF inhibited COL1A2 transcription in cultured HSC and suppressed activation of COL1A2 promoter in liver tissue induced by carbon tetrachloride administration.

The loss of Smad3 also interferes with TGF-beta-mediated induction of EMT and genes for collagens, plasminogen activator inhibitor-1 and the tissue inhibitor of metalloprotease-1.
Smad3 null mice are resistant to radiation-induced cutaneous fibrosis, bleomycin-induced pulmonary fibrosis, carbon tetrachloride-induced hepatic fibrosis as well as glomerular fibrosis induced by induction of type 1 diabetes with streptozotocin.

Zhong Xi Yi Jie He Xue Bao. 2009 Jul;7(7):642-50.

METHODS: A total of 150 SD rats were divided into three groups: blank group, carbon tetrachloride (C (4)) group and ALF-inducing group.
