摘 要:目的研究塞来昔布在体外对人结肠癌细胞Caco-2生长增生及其抗肿瘤的相关分子机制。方法体外培养人结肠癌细胞Caco-2,MTY法检测塞来昔布在相同浓度下,不同时间对于结肠癌细胞增生的影响,并计算Ic。值;RT—PCR法检验COX-2、Survivin的mRNA的表达影响。结果MTF结果显示:相同干预浓度塞来昔布抑制人结肠癌细胞增生,其24h,48h,72h的Ic。分别为:(99.519±10.355)μmol/L、(71.546±6.446)μmol/L、(59.622±15.999)μmol/L;RT-PCR结果显示:人结肠癌细胞Caco-2正常对照组及塞来昔布干预组COX-2mRNA灰度值分别为:0.808±0.021、0.101±0.002(t=19.037,P=0.000);Survivin mRNA灰度值分别为:0.798±0.031、0.190±0.002(t=18.987,P=0.002)。结论塞来昔布抑制结肠癌细胞增生,塞来昔布抗肿瘤机制可能是通过抑制COX-2及Survivin的mRNA的表达来实现的。Objective To study celecoxib in vitro human colon cancer cell growth and proliferation of Caco-2 and its anti-tumor molecular mechanisms. Methods Cultured human colon cancer Caco-2, MTT method analyses celecoxib at the same concentration, at different times for the colon cancer cell proliferation and calculate IC50 value. RT-PCR method used to evaluate the expression of COX-2, Survivin mRNA. Results MTT assay showed: the concentration of the same intervention celecoxib to inhibit the proliferation of human colon cancer cells, its 24 h, 48 h,72 h IC50 of respectively: (99. 519 ±10. 355) μmol/L, (71. 546 ±6. 446)μmol/L, (59. 622 ±15. 999)μmol/L. The RT-PCR results show: human colon cancer cells Caco-2 normal control group and celecoxib in the intervention group, respectively, the COX-2 mRNA gray value for: 0. 873 ±0. 026, 0. 115 ±0. 008, P 〈 0.05 ; SURVIVIN mRNA gray values were : 0. 808 ±0. 021,0. 101 ±0. 002 ( t = 19. 037, P = 0. 000 ) ; Survivin mRNA were O. 798 ±0. 031,0. 190 ±0. 002 ( t = 18. 987, P = 0. 002 ). Conclusions Celecoxib inhibition of colon cancer cell proliferation, celecoxib antitumor mechanisms may by inhibiting the expression of COX-2 and Survivin mRNA in implementation.
