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

(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

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

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.
