          摘   要  目的  探究安罗替尼通过调控核因子κB(NF-κB)信号通路对脑胶质瘤细胞恶性表型的影响。方法  体外培养人脑胶质
          瘤T98G细胞,以5-氟尿嘧啶为阳性对照药物,考察不同浓度(5、10、20 μmol/L)安罗替尼对该细胞增殖、黏附、迁移、侵袭能力和上
          皮间质转化(EMT)相关蛋白[上皮钙黏着蛋白(E-cadherin)、神经钙黏着蛋白(N-cadherin)、波形蛋白(vimentin)、纤维连接蛋白
         (FN)]表达的影响,并通过加入NF-κB信号通路抑制剂(BAY 11-7082)和激活剂(prostratin)来验证安罗替尼上述作用的可能机制。
          结果  5、10、20 μmol/L的安罗替尼均可显著降低细胞的增殖活力(5 μmol/L安罗替尼组除外)和迁移率,显著减少黏附细胞数和侵
          袭细胞数,显著上调 E-cadherin蛋白的表达并下调 N-cadherin、vimentin、FN 蛋白的表达(P<0.05),且 20 μmol/L安罗替尼的作用
          与阳性对照药物相当(P>0.05);与 10 μmol/L 安罗替尼比较,通路抑制剂可使细胞增殖、黏附、迁移、侵袭能力以及 N-cadherin、
          vimentin、FN、磷酸化NF-κB p65蛋白的表达显著降低,E-cadherin蛋白的表达显著上调(P<0.05),而通路激活剂则可使上述指标
          显著逆转(P<0.05)。结论  安罗替尼可抑制人脑胶质瘤T98G细胞的增殖、黏附、迁移和侵袭,上述作用可能与通过抑制NF-κB信
          号通路进而抑制细胞EMT样进程有关。

          ABSTRACT    OBJECTIVE  To  investigate  the  effects  of  anlotinib  on  the  malignant  phenotype  of  glioma  cells  by  regulating  the
          nuclear  factor-κB (NF-κB)  signaling  pathway.  METHODS  Human  glioma  T98G  cells  were  cultured  in  vitro,  and  5-fluorouracil
          was used as positive control to investigate the effects of different concentrations of anlotinib (5, 10, 20 μmol/L) on the ability of
          proliferation,  adhesion,  migration  and  invasion,  the  expressions  of  epithelial-mesenchymal  transition (EMT)  related  proteins
          [E-cadherin,  N-cadherin,  vimentin  and  fibronectin (FN)].  NF- κB  signaling  pathway  inhibitor (BAY  11-7082)  and
          activator (prostratin)  were  additionally  used  to  verify  the  possible  mechanism  of  the  above  effects  of  anlotinib.  RESULTS
          Anlotinib  with  5,  10,  20  μmol/L  could  significantly  decrease  the  activity  of  cell  proliferation (except  for  5  μmol/L  anlotinib
          group),  migration  rate,  and  the  number  of  adherent  cells  and  invasive  cells,  could  significantly  up-regulate  the  expression  of
          E-cadherin  protein  while  down-regulate  the  expressions  of  N-cadherin,  vimentin  and  FN  protein (P<0.05);  the  effect  of  20  μmol/L
          anlotinib  was  similar  to  that  of  positive  control (P>0.05).  Compared  with  10  μmol/L  anlotinib,  pathway  inhibitor  could
          significantly  decrease  the  ability  of  proliferation,  adhesion,  migration  and  invasion,  and  the  expressions  of  N-cadherin,  vimentin,
          FN  and  phosphorylated  NF-κB  p65  protein,  while  could  significantly  up-regulate  the  expression  of  E-cadherin  protein (P<0.05);
          above  indexes  were  reversed  significantly  by  pathway  activator  (P<0.05).  CONCLUSIONS  Anlotinib  may  inhibit  the
          proliferation,  adhesion,  migration  and  invasion  of  human  glioma  T98G  cells,  which  may  be  associated  with  the  inhibition  of  the
          NF-κB signaling pathway, thus inhibiting cell EMT-like processes.
