          摘   要 目的 研究毛萼乙素对结肠癌细胞上皮间质转化(EMT)的影响及机制。方法 以结肠癌细胞 HT29、HCT116 为研究对
          象。采用划痕愈合实验和Transwell实验检测毛萼乙素对2种细胞迁移和侵袭能力的影响;采用Western blot法检测毛萼乙素(1.0
          μmol/L)、毛萼乙素+Wnt/β-联蛋白(β-catenin)信号通路激动剂 Licl(1.0 μmol/L 毛萼乙素+10 mmol/L Licl)或毛萼乙素+Wnt/β-
          catenin 信号通路抑制剂 XAV939(1.0 μmol/L 毛萼乙素+10 μmol/L XAV939)对 2 种细胞的 EMT 相关蛋白[E-钙黏蛋白(E-
          cadherin)、N-钙黏蛋白(N-cadherin)、锌指转录抑制因子 Snail]和 Wnt/β-catenin 信号通路相关蛋白[β-catenin、原癌基因蛋白质 c-
          myc、细胞周期蛋白 D1(cyclin D1)、T 细胞因子 4(TCF4)]表达的影响。结果 毛萼乙素可显著抑制 2 种细胞的侵袭和迁移(P<
          0.01),并显著降低 2 种细胞中 N-cadherin、Snail、β-catenin、c-myc、cyclin D1、TCF4 表达水平,显著升高 E-cadherin 表达水平(P<
          0.05或P<0.01)。毛萼乙素与Licl联用后,2种细胞中β-catenin、c-myc、cyclin D1、TCF4及N-cadherin表达水平被逆转(P<0.05或
          P<0.01);与 XAV939 联用后,2 种细胞中 β-catenin、N-cadherin 的表达进一步下调(P<0.05 或 P<0.01),E-cadherin 的表达进一步
          上调(P<0.01),且细胞迁移率也显著降低(P<0.01)。结论 毛萼乙素可通过抑制Wnt /β-catenin通路激活抑制结肠癌细胞上皮间
          质转化。

          ABSTRACT    OBJECTIVE To study the effects and mechanism of eriocalyxin B (EriB) on epithelial-mesenchymal transition
         (EMT)of colon cancer cells. METHODS The colon cancer cells HT29 and HCT116 as research objects. Scratch-healing assay and
          Transwell assay were used to detect the effects of EriB on migration and invasion of two kinds of cells. Western blot method was
          used to detect the effects of EriB(1.0 μmol/L),EriB+Wnt/β-catenin signaling pathway agonist Licl(1.0 μmol/L EriB+10 mmol/L
          Licl)or EriB+Wnt/β-catenin signaling pathway inhibitor XAV939(1.0 μmol/L EriB+10 μmol/L XAV939)on the expressions of
          EMT related proteins [E-cadherin,N-cadherin,Snail] and Wnt/β -catenin signaling pathway related proteins [β -catenin,c-myc,
          cyclin D1,TCF4]. RESULTS EriB can significantly inhibit the invasion and migration of two kinds of cells (P<0.01). EriB
          significantly reduced the protein expressions of N-cadherin,Snail,β -catenin,c-myc,cyclin D1 and TCF4 while increases the
          protein expression of E-cadherin(P<0.05 or P<0.01). After EriB combined with Licl,the protein expressions of β-catenin,c-
          myc,cyclin D1 and TCF4 in the two kinds of cells were reversed (P<0.05 or P<0.01). After combined with XAV939,the
          protein expressions of β-catenin and N-cadherin were further down-regulated(P<0.05 or P<0.01);the protein expression of E-
                                                              cadherin was further up-regulated(P<0.01),while migration
