- Abstract: Objective To predict the target and molecular mechanism of Huayu Xiaopi decoction in the intervention of Precancerous lesions of gastric cancer(PLGC)based on network pharmacology and molecular docking technology,and to conduct experimental verification.Methods A total of 60 SPF SD male rats were randomly selected as blank control,and the other rats were replicated in PLGC model.After successful modeling,the rats were randomly divided into model group,folic acid group(2 mg·kg-1·d-1),Huayu Xiaopi decoction high,medium and low dose groups(24.8,12.4,6.2 g·kg-1·d-1),which were continuously administered for 90 days.The body mass and food intake of rats at 3 h were recorded,and the gastric histopathology was observed by HE staining.Network pharmacology and molecular docking techniques were used to predict the potential targets of Huayu Xiaopi decoction in PLGC intervention,and the core targets were verified by Western blot technique.Results Compared with the blank group,the body mass and 3 h food intake of rats in the model group were significantly decreased(P<0.05),the gastric mucosa of rats was significantly thinner,the glands were significantly reduced and disordered,and the intestinal metaplasia goblet cells and a large number of inflammatory cells were visible in some areas.Compared with the model group,the body mass and 3 h food intake of rats in each administration group were improved to varying degrees.Huayu Xiaopi Decoction improved significantly in medium and high doses(P<0.05),the gastric mucosa was repaired in different degrees,the glandular arrangement tended to be orderly,and the inflammatory cells in the interstitial were gradually reduced.The results of network pharmacology and molecular docking showed that TP53,JUN and MAPK3/1(ERK1/2)were the core targets of Huayu Xiaopi decoction in the intervention of PLGC.Molecular biological detection results showed that compared with blank group,the protein phosphorylation levels of TP53,c-Jun and ERK1/2 in gastric tissue of model group were significantly increased(P<0.05).Compared with model group,the protein phosphorylation levels of TP53,c-Jun and ERK1/2 in gastric tissue of rats in all administration groups were decreased to different degrees,and significantly decreased in Huayu Xiaopi decoction high-dose and medium-dose groups(P<0.05).Conclusion Huayu Xiaopi Decoction can significantly improve the survival condition of PLGC rats and promote gastric mucosal repair,the specific mechanism of which may be related to the decrease of ERK1/2,c-Jun and TP53 protein phosphorylation levels in gastric tissue of PLGC rats,and then regulate the downstream signaling molecular response.
