ABSTRACT OBJECTIVE To investigate the mechanism of isochlorogenic acid A against hepatocellular carcinoma based on the
phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway and multi-
omics technology. METHODS The invasion rate and migration rate of human hepatocellular carcinoma HepG2 cells after 48 h of
intervention with 0 (control group), 0.25 and 0.5 mg/mL isochlorogenic acid A were examined; mRNA expression of DEP domain-
containing mTOR-interacting protein (DEPTOR), the protein expressions of mTOR, PI3K and phosphatase and tensin homologue
deleted on chromosome ten (PTEN), as well as the phosphorylation level of Akt protein were determined in the cells.
Metabolomics analysis was performed using liquid chromatography-tandem mass spectrometry, and differential metabolites were
screened and subjected to Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis; transcriptomics
monitoring was conducted by RNA sequencing, and
