          原酸A抗肝癌的作用机制。方法  分别考察0(对照组)、0.25、0.5 mg/mL的异绿原酸A干预人肝癌HepG2细胞48 h的侵袭率、迁移
          率,细胞中含DEP结构域的mTOR相互作用蛋白(DEPTOR)mRNA和mTOR、PI3K、第10号染色体缺失的磷酸酶及张力蛋白同源
          物(PTEN)蛋白表达量以及Akt蛋白磷酸化水平。采用液相色谱-串联质谱法进行代谢组学检测,筛选差异代谢物并进行京都基因
          与基因组百科全书(KEGG)通路富集分析;采用RNA测序进行转录组学检测,筛选差异表达基因并进行基因本体(GO)功能注释
          及KEGG通路富集分析。结果  与对照组比较,0.25、0.5 mg/mL异绿原酸A干预48 h能显著抑制HepG2细胞侵袭率和迁移率,显
          著上调 DEPTOR mRNA 和 PTEN 蛋白表达量,显著下调 PI3K 蛋白表达量和 Akt 蛋白磷酸化水平(0.25 mg/mL 异绿原酸 A 除外)
         (P<0.05)。多组学分析共筛选出304个差异代谢物、212个差异表达基因;KEGG通路富集分析提示,异绿原酸A主要通过抑制
          PI3K/Akt信号通路,协同mTOR信号通路、铁死亡及磷酸戊糖途径、嘌呤/嘧啶代谢等代谢重编程过程,对HepG2细胞生长关键信

          及嘌呤/嘧啶代谢、诱导铁死亡等相关。

          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
