Abstract
AIM: To investigate the effects of cocktail therapy on the expression of transforming growth factor-β1 (TGF-β1), collagen I (COL I) and collagen III (COL III) in carbon tetrachloride-induced liver fibrosis in rats.
METHODS: Hepatic fibrosis was induced in rats with carbon tetrachloride. Wistar rats were divided into 7 groups: normal group, model group, colchicine group, taurine group, epigallocatechin gallate (EGCG) group, genistein group and cocktail therapy group. The rats were sacrificed at week 10 after treatment. The deposition of collagen in liver tissue was observed by HE staining. The expression of TGF-β1, COL I and COL III in hepatic tissue was detected by immunohistochemistry.
RESULTS: A significant reduction in collagen deposition and disorganization was noted in the cocktail therapy group when compared with the model group. The expression levels of TGF-β1, COL I and COL III in the cocktail therapy group, genistein group, EGCG group and taurine group, compared with the model group, markedly decreased (TGF-β1: 2.57 ± 0.23, 4.21 ± 0.35, 4.93 ± 0.21 and 4.81 ± 0.16 vs 12.11 ± 0.62, all P < 0.05; COL I: 2.69 ± 0.10, 4.88 ± 0.42, 5.04 ± 0.31 and 4.79 ± 0.29 vs 13.06 ± 0.24, all P < 0.05; COL III: 3.17 ± 0.42, 5.73 ± 0.23, 5.51 ± 0.25 and 5.24 ± 0.18 vs 15.15 ± 0.43, all P < 0.05). Cocktail therapy had a more significant inhibitory effect on the expression of these proteins than other agents tested (all P < 0.05).
CONCLUSION: Cocktail therapy has an obvious protective effect against liver fibrosis in rats possibly by remarkably inhibiting TGF-β1, COL I and COL III expression in liver tissue.
