Investigation on the mechanism of Shaoyao-Gancao Decoction in the treatment of gastric carcinoma based on network pharmacology and experimental verification

Abstract

Background: Shaoyao-Gancao Decoction (SG-D) is a famous classical Chinese prescription that has been used in the treatment of numerous kinds of diseases. However, its mechanism of action in the treatment of Gastric carcinoma (GC) is not clear. Methods: The active ingredients and targets of SG-D were screened using network pharmacology, and GC-related targets were retrieved through several databases. The protein-protein interaction network was then further constructed and GO and KEGG enrichment analysis were performed. Subsequently, molecular docking was carried out. Finally, we validated the results of the network pharmacology by performing in vitro cell experiments on CCK-8, apoptosis, cell cycle, platelet clone formation, and Western blotting with AGS cells. Results: Three key active ingredients and 8 core targets were screened through a network pharmacological analysis, and the results of the KEGG indicated that the PI3K/Akt and MAPK signaling pathways are critical signaling pathways for SG-D to treat GC. Experimental results revealed that SG-D was able to inhibit AGS cells proliferation, induce apoptosis and arrest the cell cycle, and reduce the ability of cell clone formation by regulating the PI3K/Akt and MAPK signaling pathways. Conclusions: Network pharmacology has shown that SG-D can act on multiple targets through multiple ingredients and treat GC by regulating multiple signaling pathways. In vitro cell experiments have also confirmed this, so as to provide a reference for subsequent related research.

Investigation on the mechanism of the combination of eremias multiocellata and cisplatin in reducing chemoresistance of gastric cancer based on in vitro and in vivo experiments

“…The above results indicated that EM combined with DDP could effectively inhibit the migration and invasion ability of MKN45/DDP cells. Apoptosis is involved in tumor development as a death mechanism regulated by multiple apoptotic genes [ 12 ]. Our in vitro experiments showed that the apoptosis rate of drug-resistant cells increased to varying degrees in each treatment group compared to the control group, with the highest rate observed in the combination group.…”

Rapid chemical characterization and pharmacological mechanism of Fining Granules in the treatment of chronic bronchitis based on UHPLC–Q-exactive orbitrap mass spectrometer and network pharmacology

“…Various studies have used LC–MS to improve detection capabilities for traditional medicinal plant [ 9 , 10 ]. Network pharmacology is recognized for its cost-effectiveness in drug development and is a promising approach for studying compound–proteins/genes–disease pathways, such as the pharmacological mechanisms of traditional Chinese medicine [ 11 ]. This technique offers valuable insights into analysis of complex plant metabolites and Quality control.…”
