摘要:

目的 探讨外源性CXC趋化因子配体10(CXCL10)对肝细胞癌(HCC)SMMC-7721细胞增殖和迁移的影响,并阐明其作用机制。 方法 按照CXCL10作用浓度,将人HCC SMMC-7721细胞分为0 mg· L-1 CXCL10组、10 mg·L-1 CXCL10组和30 mg·L-1 CXCL10组。上述部分细胞给予细胞外调节蛋白激酶(ERK)抑制剂PD98059(80 μmol· L-1)后,将SMMC-7721细胞分为0 mg·L-1 CXCL10+PD98059组、10 mg·L-1 CXCL10+PD98059组和30 mg·L-1 CXCL10+PD98059组。CCK-8法检测各组SMMC-7721细胞增殖率,EdU法检测各组SMMC-7721细胞中EdU阳性表达率,Transwell小室实验检测各组SMMC-7721细胞迁移率,Western blotting法检测各组SMMC-7721细胞中ERK、磷酸化ERK(p-ERK)和细胞周期蛋白D1(Cyclin D1)蛋白表达水平。 结果 CCK-8法检测,培养24 h后,与0 mg·L-1 CXCL10组比较,10 mg·L-1 CXCL10和30 mg·L-1 CXCL10组SMMC-7721细胞增殖率升高(P<0.05或P<0.01)。EdU法检测,与0 mg·L-1 CXCL10组比较,10 mg·L-1 CXCL10和30 mg·L-1 CXCL10组SMMC-7721细胞中EdU阳性表达率升高(P<0.01);Transwell小室实验检测,培养48 h后,与0 mg·L-1 CXCL10组比较,10 mg·L-1 CXCL10和30 mg·L-1 CXCL10组SMMC-7721细胞迁移率升高(P<0.01)。Western blotting法检测,细胞培养24 h后,采用CXCL10溶液处理24 h,与0 mg·L-1 CXCL10组比较,10 mg· L-1 CXCL10组和30 mg·L-1 CXCL10组SMMC-7721细胞中ERK、p-ERK及Cyclin D1蛋白表达水平升高(P<0.01)。CCK-8法检测,加入ERK抑制剂PD98059后,与0 mg·L-1 CXCL10组比较,10 mg·L-1 CXCL10+PD98059组和30 mg·L-1 CXCL10+PD98059组SMMC-7721细胞增殖率降低(P<0.05);与10 mg·L-1 CXCL10组比较,10 mg·L-1 CXCL10+PD98059组SMMC-7721细胞增殖率降低(P<0.05);与30 mg·L-1 CXCL10组比较,30 mg·L-1 CXCL10+PD98059组SMMC-7721细胞增殖率降低(P<0.05)。 结论 CXCL10能够促进HCC SMMC-7721细胞增殖和迁移,其作用机制与上调ERK/p-ERK/Cyclin D1通路蛋白表达有关。

Abstract:

Objective To discuss the effect of exogenous CXC chemokine ligand 10(CXCL10) on the proliferation and migration of the hepatocellular carcinoma(HCC)SMMC-7721 cells, and to clarify its mechanism. Methods The human HCC SMMC-7721 cells were divided into 0 mg·L-1 CXCL10 group,10 mg·L-1 CXCL10 group,and 30 mg·L-1 CXCL10 group according to the CXCL10 concentration. Some of the above cells were treated with extracellular regulated protein kinase(ERK) inhibitor PD98059 (80 μmol·L-1), then the SMMC-7721 cells were divided into 0 mg·L-1 CXCL10+PD98059 group, 10 mg·L-1 CXCL10+PD98059 group, and 30 mg·L-1 CXCL10+PD98059 group. The proliferation rates of the SMMC-7721 cells in various groups were detected by CCK-8 method; the EdU positive expression rates in SMMC-7721 cells in various groups were detected by EdU method; the migration rates of the SMMC-7721 cells in various groups were detected by Transwell chamber assay; the expression levels of ERK, phosphorylated ERK(p-ERK), and Cyclin D1 proteins in the SMMC-7721 cells in various groups were detected by Western blotting method. Results The CCK-8 results showed that after cultured for 24 h, compared with 0 mg·L-1 CXCL10 group, the proliferation rates of the cells in 10 mg·L-1 CXCL10 group and 30 mg·L-1 CXCL10 group were increased (P<0.05 or P<0.01);the EdU detection results showed that compared with 0 mg·L-1CXCL10 group, the positive expression rates of EdU in the cells in 10 mg·L-1 CXCL10 group and 30 mg·L-1CXCL10 group were increased (P<0.01). The Transwell chamber assay results showed that after cultured for 48 h, compared with 0 mg·L-1 CXCL10 group, the migration rates of the cells in 10 mg·L-1CXCL10 group and 30 mg·L-1 CXCL10 group were increased (P<0.01).The Western blotting results showed that after cultured for 24 h and treated with CXCL10 for 24 h,compared with 0 mg·L-1 CXCL10 group, the expression levels of ERK, p-ERK,and Cyclin D1 proteins in the SMMC-7721 cells in 10 mg·L-1 CXCL10 group and 30 mg·L-1 CXCL10 group were increased (P<0.05). The CCK-8 method results showed that after treated with ERK inhibitor PD98059, compared with 0 mg·L-1 CXCL10 group, the proliferation rates of the SMMC-7721 cells in 10 mg·L-1 CXCL10+PD98059 group and 30 mg·L-1 CXCL10+PD98059 group were decreased (P<0.05); compared with 10 mg·L-1 CXCL10 group, the proliferation rate of the SMMC-7721 cells in 10 mg·L-1 CXCL10+PD98059 group was decreased (P<0.05); compared with 30 mg·L-1 CXCL10 group, the proliferation rate of the SMMC-7721 cells in 30 mg·L-1 CXCL10+PD98059 group was decreased (P<0.05). Conclusion CXCL10 can promote the proliferation and migration of the HCC SMMC-7721 cells, and its mechanism is mainly related to the up-regulation of the expressions of ERK/p-ERK/Cyclin D1 pathway proteins.
