Hepatic fibrosis was induced using 5 ml/kg 40% CCl4 in corn oil tree time weekly for three or four weeks in all groups, except for the normal control group

Hepatic fibrosis was induced using 5 ml/kg 40% CCl4 in corn oil tree time weekly for three or four weeks in all groups, except for the normal control group. liver expression levels of AGTR1 and the plasma expression levels of H2S were detected using western blot analyses. The results indicated that the severity of hepatic fibrosis, the serum expression levels of HA, LN, PcIII, cIV, ALT, and AST, the liver expression levels of CSE and AGTR1, and the plasma expression levels of H2S were significantly higher in the PAG group, as compared with the model group (P<0.05). Conversely, the expression levels of ALB were significantly lower in the PAG group, as compared with the model group. In addition, the severity of hepatic fibrosis, the serum expression levels of HA, LN, PcIII, cIV, ALT, and AST, the liver expression levels of CSE and AGTR1, and the plasma expression levels of H2S were significantly lower in the NaHS group, as compared with the model group (P<0.05). These results suggest that endogenous H2S is usually Gabapentin Hydrochloride associated with CCl4-induced hepatic fibrosis in rats, and may exhibit anti-fibrotic effects. Furthermore, H2S reduced the liver expression levels of AGTR1, which may Pdgfra be associated with the delayed progression of hepatic fibrosis. access to drinking water, and underwent a 12 h light/dark cycle. Hepatic fibrosis was induced using 5 ml/kg 40% CCl4 in corn oil tree time weekly for three or four weeks in all groups, except for the normal Gabapentin Hydrochloride control group. The rats in the PAG group were intraperitoneally injected with 45 (22) reported that H2S administration attenuated hepatic fibrosis and collagen I protein expression in rats exhibiting CCl4-induced hepatic fibrosis, inhibited cellular proliferation, and induced cell cycle arrest and apoptosis of activated HSCs. Jha (23) exhibited that H2S significantly attenuated hepatic I/R injury via preservation of the intracellular redox balance and inhibition of apoptosis during I/R injury. These results suggested that H2S may serve as a encouraging therapeutic agent in the treatment of hepatic I/R injury. HSCs have a crucial role in the onset of hepatic fibrosis. HSCs express AGTR1 (15), and are activated by the binding of angiotensin II to AGTR1, which in turn leads to the secretion of extracellular matrix components resulting in the development of hepatic fibrosis (24). Activated HSCs also express numerous cytokines, which accelerate hepatic inflammation (24). Fibrogenesis in chronic liver disease is usually stimulated by angiotensin II via AGTR1, and may be modulated by angiotensin-converting enzyme inhibitors and AGTR1 antagonists (25,26). In the present study, advanced liver fibrosis was effectively induced by CCl4. The results of the present study demonstrated that this protein expression levels of AGTR1 were negatively correlated with the degree of liver fibrosis. T?x (27) showed that angiotensin II may influence transforming growth factor (TGF)–mediated processes via AGTR1, by enhancing Smad2 gene expression in the liver. Tan (28) previously investigated the protective role of H2S on CCl4-induced acute hepatotoxicity, as well as the prophylactic and therapeutic effects of H2S on long-term CCl4-induced cirrhosis and portal hypertension, mediated Gabapentin Hydrochloride by the multiple functions of H2S, including antioxidation, anti-inflammation, cytoprotection, and anti-fibrosis. The results of the study indicated that the use of H2S may provide potent therapeutic effects against liver cirrhosis and portal hypertension. The regulation of sinusoidal resistance depends on the aggregation of HSCs around sinusoidal endothelial cells (29). A previous study exhibited that H2S is an autocrine neurotransmitter that is involved in the regulation of HSC contraction and the maintenance of portal venous pressure via KATP channels (29). H2S counteracts impaired vasodilation and HSC contraction, thus reducing portal hypertension in cirrhotic livers (29). Angiotensin II has been shown to increase the expression levels of hepatic TGF-1 during the development of hepatic fibrosis (30). Connective tissue growth factor (CTGF) is usually a hepatic profibrotic mediator, which is a downstream.
