Ge-Zhi-Jie-Jiu decoction alleviates alcoholic liver disease through multiple signaling pathways

Alcoholic liver disease (ALD) is a growing public health concern caused by excessive alcohol consumption, but effective treatments are limited. Ge-Zhi-Jie-Jiu decoction (JJY) is a modified traditional Chinese herbal remedy that aims to alleviate ALD. This formula contains various components such as Ge Hua, Ge Gen, Zhi Ju Zi, and other medicinal-food herbs. However, the specific pharmacotherapeutic compounds of JJY and its pharmacological mechanisms remain unclear.

This study aimed to elucidate the molecular mechanism and pharmacodynamic basis of JJY in treating ALD.

UPLC-Q-Orbitrap HRMS, HPLC fingerprinting, and LC-MS techniques were used for the composition identification and quality control of JJY. The pharmacological components and molecular mechanisms of JJY in anti-ALD were then predicted using network pharmacology and molecular docking approaches. Ultimately, an acute alcoholic liver injury mouse model was developed, and the potential mechanisms were verified by hematoxylin-eosin (H&E), Oil Red O, and TUNEL staining, real-time fluorescence quantitative PCR (RT-qPCR), Western blot (WB) and molecular docking analysis.

The results showed that the main components of JJY are organic acids, flavonoids, and isoflavonoids, in which puerarin, daidzein, glycitein, ononin, quercetin, and tectorigenin can be used as the indicator components of JJY. In addition, JJY might ameliorate ALD through several pathways, including potentially promoting alcohol metabolism via alcohol-metabolizing enzymes, and possibly inhibiting oxidative stress, inflammation and apoptosis via the Nrf2/Keap1/HO-1 and MAPK signaling pathways. Furthermore, JJY may also alleviated hepatic lipid accumulation through the PPARα signaling pathway.

JJY has significant anti-ALD efficacy with multiple mechanisms. This study offers a solid experimental foundation for JJY's development as a medicine with anti-ALD characteristics and elucidates its probable active components.
