Effects of Qishu Granule on PI3K/Akt Signaling Transduction Pathways in the Process of Hepatic Fibrosis / 中国中医药信息杂志

ABSTRACT

Objective To observe the effects of Qishu granule on PI3K/Akt signaling transduction pathways in the process of hepatic fibrosis, and further explain the anti-hepatic fibrosis mechanism of Qishu granule.Methods Wistar rats were randomly divided into normal group, model group, experimental control group and Qishu granule group. Liver fibrosis was duplicated in rats by intraperitoneal injection of CCl4, and the rats were given appropriate treatment at the same day. Rats in Qishu granule group were given a gavage 2 g/(kg?d), 1.0 mL/100 g, while rats in experimental control group and normal group were given the same amount of aquae sterilisata. Rats in each group were taken liver tissue samples in the 1st, 2nd and 4th week, and were checked for the protein expression levels of p-Akt (Ser473), p-Akt (Thr308), Bad (Ser136) and Caspase9 by Western blot.Results Compared with the model group, expression levels of p-Akt (Ser473), p-Akt (Thr308), Bad (Ser136) and Caspase9 in model and Qishu granule groups increased in every time points (P0.05).Conclusion Qishu granule could regulate PI3K/Akt signaling transduction pathways, and inhibit the occurrence and development of liver fibrosis.
