AIM OF THE STUDY: To test the hypothesis that therapeutic effects of DHZCP on hepatic fibrosis are conferred by regulating cytokine profile through a mitogen activated protein kinase (MAPK) pathway.
MATERIALS AND METHODS: Hepatic fibrosis is inducted by carbon tetrachloride (CCl(4)) in rats which then were randomly divided into six groups: hepatic fibrosis model group, high dose DHZCP group, low dose DHZCP group, Fufang Biejia Ruangan Pian (FBRP) group, Colchicine group and control group. Pathological, immunohistochemical, multiplex immunoassay and protein expression studies (Western blotting) are performed.
RESULTS: DHZCP significantly decreases the levels of alanine aminotransferase, aspartate aminotransferase, hyaluronic acid, laminin, type IV collagen and procollagen III, and reverses hepatic fibrosis in rat model. DHZCP also could reduce the expression of α-smooth muscle actin, and lower the serum level of tumor necrosis factor alpha (TNF-α) and interleukin 13 (IL-13). The expressions of phosphorylated p38 MAPK and extracellular signal-regulated kinase (ERK) are down-regulated, while no significant changes are found in phosphorylation of c-Jun N-terminal kinase (JNK).
CONCLUSIONS: DHZCP can alleviate hepatic fibrosis induced by CCl(4). The anti-fibrotic effects of DHZCP are conferred by decreasing the secretion of TNF-α and IL-13 through down-regulating p38 and ERK phosphorylation.
