Development of A Novel Anti-Liver Fibrosis Formula with luteolin, licochalcone A, aloe-emodin and acacetin by network pharmacology and transcriptomics analysis

Abstract

Background: Liver fibrosis leads to loss of liver function. Xiaoyaosan decoction (XYS) as a classical Traditional Chinese Medicine (TCM) formula is used to treatment liver fibrosis in clinical and alleviated CCl4-induced liver fibrosis in our previous study.Xiaoyaosan decoction was composed of many ingredients, and the active ingredients is not clear. The Aim of this study is to explore the clarified compounds or compound combinations to treat liver fibrosis.Methods: Network pharmacology combined with transcriptomics analysis were used to analyze the Xiaoyaosan decoction (XYS) and liver depression and spleen deficiency syndrome liver fibrosis. This consisted constructed XYS-Syndrome-liver fibrosis network, the predict formula named LLAAF was develop from the network by topological analysis according to network stability. The anti-fibrosis effect was evaluated by in vitro and in vivo study.Results: According to the network XYS-Syndrome-liver fibrosis network, luteolin, licochalcone A, aloe-emodin, and acacetin formula (LLAAF) was predicted from 8 key compounds and 255 combinations in XYS, and LLAAF had a synergistic effect on the proliferation inhibition of hepatic stellate cells (HSCs) compared to each individual compound alone. The treatment of XYS and LLAAF showed a similar anti-liver fibrotic effect that reduced histopathological changes of liver fibrosis, Hyp content and levels of α-SMA and collagen I in CCl4-induced liver fibrosis in rat. Transcriptomics analysis revealed LLAAF regulated PI3K-Akt, AMPK, FoxO, Jak-STAT3, P53, cell cycle, focal adhesion, and PPAR signaling. Furthermore, LLAAF was confirmed to regulate Jak-STAT and PI3K-Akt-FoxO signaling in vitro and in vivo.Conclusions: This study developed a novel anti-liver formula, LLAAF from XYS demonstrated the anti-liver fibrotic activity may be involved in the regulation of Jak-STAT and PI3K-Akt-FoxO signaling.
