Mechanism of Modified Taohe Chengqitang in Treating Diabetic Gastroparesis Based on Network Pharmacology
To study the mechanism of modified Taohe Chengqitang in preventing and treating diabetic gastroparesis by regulating relative genes and signaling pathways based on network pharmacology.
Method:
2
Target genes of modified Taohe Chengqitang were obtained from Bioinformatics Analysis Tool for Molecular Mechanism of TCM (BATMAN-TCM) database
and target genes of diabetic gastroparesis were obtained from Comparative Toxicogenomics Database (CTD) database. The target genes of modified Taohe Chengqitang-diabetic gastroparesis intersection protein were obtained through the integration of two groups of genes. STRING was used to build the protein-protein interaction network and visualize the results. Cytospace software ClueGO
CluePedia plug-in were used for gene ontology (GO) analysis and enrichment analysis of KEGG pathway of modified Taohe Chengqitang-diabetic gastroparesis target genes intersection
and results were visualized. Finally
CTD database and literatures were used to obtain intersection genes in the treatment of diabetic gastroparesis.
Result:
2
Among 621 target genes in modified Taohe Chengqitang
25 were related to diabetic gastroparesis. By regulating expressions of MLNR
SST
PTGS1
HRH2
HTR3A
HTR4
HTR7
NOS3 and other intersection genes
Taohe Chengqitang could improve the gastrointestinal hormone levels
affected the combination of serotonin and its receptors
activated adenylate cyclase (AC)
and induced cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA)
so as to activiate AC/cAMP/PKA signaling pathway
regulate Ca

channel
control ion balance
promote the adaptability of gastric smooth muscle
and contract gastric smooth muscle to regulate gastric volume. At the same time
gastric acid secretion was improved to protect gastric mucosa
which may help improve vasoconstriction and hemodynamics.
Conclusion:
2
Based on the network pharmacology
modified Taohe Chengqitang has multiple mechanisms in the prevention and treatment of diabetic gastroparesis. This study explored relevant signaling pathways
advantages and research directions of modified Taohe Chengqitang in treatment of diabetic gastroparesis.
