摘要: 目的 探讨肝再生磷酸酶-3(PRL-3)抗体和培美曲塞(Pem)单用及联用对人肺腺癌细胞系A549增殖、迁移和凋亡的影响。方法 不同浓度PRL-3抗体处理A549细胞;CCK-8法测细胞增殖抑制率;Transwell小室法检测细胞迁移能力;流式细胞仪检测细胞凋亡率;Western bolt检测PRL-3、磷酸化细胞外信号调节激酶(P-ERK)及血管内皮生长因子(VEGF)蛋白表达。结果 1)与对照组相比,PRL-3抗体随浓度增加,对A549细胞增殖的抑制作用增加(P<0.05);2)联合用药组对A549细胞增殖和迁移能力的抑制作用优于单药组 (P<0.05);3)联合用药组A549细胞凋亡率34.63%±1.65%高于PRL-3抗体组17.24%±1.15%和培美曲塞组15.32%±1.82%(P<0.05);4)与单药组相比,联合用药组PRL-3、P-ERK及VEGF蛋白表达下降更显著(P<0.05)。结论 PRL-3抗体联合培美曲塞可抑制A549细胞增殖、迁移并诱导凋亡,效果优于单药。其作用机制可能与抑制PRL-3、P-ERK和VEGF蛋白表达相关。

Abstract: Objective To investigate the effects of PRL-3 antibody and pemetrexed on proliferation, migration and apoptosis of A549 cells. Methods A549 cells were treated with PRL-3 antibody at different concentrations; CCK-8 method was used to measure the cell proliferation of human lung adenocarcinoma A549 cells in each group; Transwell chamber assay was used to detect cell migration ability of A549 cells; Flow cytometry assay was used to measure the apoptosis rate of A549 cells; PRL-3, P-ERK and VEGF protein expressions of A549 cells were detected by Western bolt. Results 1)Compared with the control group, the inhibitory effect of PRL-3 antibody on proliferation of A549 cells increased with the increase of PRL-3 concentration (P<0.05); 2)The inhibitory effect of the combination group on proliferation and migration ability of A549 cells was more significant than that of the monotheraphy group (P<0.05); 3)The apoptosis rate of A549 cells in the combination group 34.63%±1.65% was better than that of PRL-3 antibody group 17.24%±1.15% and pemetrexed group 15.32%±1.82% (P<0.05); 4)Compared with the monotheraphy group, the expressions of PRL-3, P-ERK and VEGF proteins in the combination group decreased more significantly (P<0.05). Conclusions PRL-3 antibody combined with pemetrexed can inhibit the proliferation, migration and induce apoptosis of A549 cells as compared to the monotherapy group. The mechanism may be attributed to the inhibition of the expressions of PRL-3, P-ERK and VEGF protein.
