摘  要:目的塞来昔布影响血管内皮细胞迁移活性作用机制研究较少。文中旨在研究塞来昔布对血管内皮细胞迁移活性的影响及机制,探讨塞来昔布抗血管生成作用机制。方法人脐静脉血管内皮(HUVEC)细胞来源为南京军区南京总医院检验科中心实验室细胞库,使用20、10、0μmol/L塞来昔布作用于HUVEC细胞,Transwell法检测细胞迁移活性变化,免疫荧光、Western blot及定量RT-PCR法检测HUVEC细胞中选择性环氧化酶2(COX-2)、受体型酪氨酸磷酸酶J(PTPRJ)的表达变化情况。结果 0、10、20μmol/L塞来昔布血管内皮细胞迁移数分别为(63.15±5.83)、(32.80±5.92)、(12.35±3.61)个,各浓度塞来昔布间细胞迁移数比较差异有统计学意义(P<0.01)。20、10μmol/L塞来昔布作用后HUVEC细胞中COX-2蛋白表达量[(0.16±0.03),(0.36±0.05)]较0μmol/L(0.77±0.07)明显减少(P<0.01),且20μmol/L塞来昔布COX-2蛋白表达量较10μmol/L降低(P<0.05)。20、10μmol/L塞来昔布PTPRJ蛋白表达量[(0.82±0.05),(0.51±0.02)]较0μmol/L(0.27±0.04)明显增加(P<0.01),且20μmol/L塞来昔布较10μmol/L升高(P<0.05)。20、10、0μmol/L塞来昔布作用后HUVEC细胞中COX-2 mRNA相对表达量分别为:(0.06±0.02)、(0.22±0.05)、(1.05±0.13),PTPRJ mRNA相对表达量分别为(60.27±11.31)、(16.50±3.18)、(0.99±0.25);20、10μmol/L塞来昔布组较0μmol/L塞来昔布COX-2 mRNA表达明显减少,PTPRJ mRNA表达明显增加(P<0.01)。结论塞来昔布抑制血管内皮细胞迁移,可能与抑制血管内皮细胞中COX-2表达,上调PTPRJ表达有关。Objective The mechanism of celecoxib in influencing the migration of vascular endothelial cells is still not clear. The aim of this study was to investigate the effect of celecoxib against migration of vascular endothelial cells and its mechanism. Methods Human umbilical vein endothelial cells (HUVECs) were obtained from the cell bank of Central Laboratory of Nanjing Gen- eral Hospital of Nanjing Military Command. Transwell was used to measure the migration rate of HUVECs after the administration of 0 μmol/L, 10μmol/L and 20 μmol/L celecoxib. Immunofluorescence, western blot, and qRT-PCR were used to detect protein and mR- NA expression of COX-2 and PTPRJ in HUVECs. Results The expression of COX-2, PTPRJ in HUVECs were detected by immuno- fluorescence. After the administration of 20 μmol./L, 10 μmol/L and 0 μmol/L celecoxib, HUVEC migration rate was (12.35±3.61),( 32.80 ±5.92 ) and ( 63. 15 ± 5.83 ) respectively, representing significant difference ( P 〈 0. 01 ). COX-2 protein expression in 20μ mol/L group (0.16±0.03) and 10 μmol/L group (0.36±0.05) decreased significantly compared with that of 0 μmol/L group (0,77±0.07) ( P〈0.01 ). Moreover, COX-2 protein expression in 20 μmol/L group significantly decreased compared with that of 10 μmol/L group( P〈 0.05 ). PTPRJ protein expression in 20 μmol/L group ( 0.82± 0.05 ) and 10 μmol/L group ( 0.51 ± 0.02 ) was respectively higher than that of 0 μmol/L group (0.27±0.04) (P〈0.01). Moreover, PTPRJ protein expression in 20 μmol/L group significantly increased compared with that of 10 μmol/L group (P〈0.05). COX-2 mRNA expression in 20 μmol/L group (0.06±0.02) and 10 μmol/L group (0.22±0.05) decreased significantly compared with that of 0 μmol/L group (1.05±0.13) (P〈0.01). PTPRJ mRNA expression in 20μmol/L group ( 60.27± 11.31 ) and 10 μmol/L group ( 16.50± 3.18 ) increased significantly compared with that of 0 μmol/L group (0.99±0.25) (
