Objective To explore the anti-aging mechanism of Kangshuailao Tablet (KSLT) based on network pharmacology and in vivo experiments. Methods Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) was used to screen the main chemical components and their targets of Chinese materia medica in KSLT and the major components of Chinese materia medica in KSLT were supplemented by literature and Pubchem, and the targets of supplemented components were predicted by the SwissTargetPrediction. Aging-related targets were obtained from the database of GeneCards and OMIM. Common targets of KSLT and aging were got by Venny2.1.0. The protein-protein interaction (PPI) network of the common targets of drugs and diseases was constructed based on the STRING and Cytoscape 3.8.0 software. Gene ontology (GO) function enrichment analysis and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis were carried out based on R language. To explore the anti-aging effect and potential mechanism of KSLP, N2 wild-type Caenorhabditis elegans (C. elegans) were performed to observe the anti-aging effect of KSLT on the life span, and the potential anti-aging mechanism of KSLT was investigated by paraquat-induced N2 wild-type C. elegans and mutants CB1370, CF1038, MQ1333, MQ887 and TJ1052. Results There were 221 active ingredients, 1 232 predicted targets in KSLT, 12 081 targets in aging-related targets, and 1 020 common targets of KSLT and aging. The selected signaling pathways of KEGG pathway analysis mainly included phosphatidylinositol 3- kinase and protein kinase B (PI3K/Akt) signaling pathway, advanced glycation end products/receptor for advanced glycation end products (AGE/RAGE) signaling pathway, mitogen-activated protein kinase (MAPK) signaling pathway, etc. The experimental results showed that KSLT prolonged the lifespan of C. elegans and improved the tolerance of C. elegans to paraquat. Compared with the corresponding control groups, KSLT was unable to extend the lifespan of mutants TJ1052 and CF1038 under oxidative stress, but the lifespan of mutants CB1370, MQ1333, and MQ887 was prolonged by KSLT under oxidative stress. Conclusion KSLTP had anti-aging effects on C. elegans, and the underlying might depend on PI3K and forkhead box protein O (FOXO) signaling pathways, but not on insulin receptors signaling pathway and mitochondria-related signaling pathways.
