2、,并觀察rhlL-24對(duì)卵巢癌SKOV3和SKOV3/DDP細(xì)胞凋亡和細(xì)胞周期的影響。方法用rhlL-24、DDP及rhlL-24聯(lián)合DDP作用于SKOV3、SKOV3/DDP細(xì)胞,以CCK-8法檢測(cè)細(xì)胞增殖、用流式細(xì)胞儀檢測(cè)細(xì)胞凋亡及周期的變化。結(jié)果rhlL一24對(duì)體外培養(yǎng)的卵巢癌SKOV3和SKOV3/DDP細(xì)胞的生長(zhǎng)有明顯抑制作用,rhlL-24聯(lián)合DDP對(duì)SKOV3/DDP細(xì)胞株抑制率為30.7%,與單用DDP組抑制率6.5%相比有顯著性差異,流式細(xì)胞儀檢測(cè)rhlL-24、DDP和rhlL-24聯(lián)合DDP各
3、組凋亡率分別為14.95%、12.99%和16.32%,與陰性對(duì)照組凋亡率1.32%比較具有顯著性差異;細(xì)胞周期檢測(cè)中,SKOV3細(xì)胞周期變化顯示rhlL-24組G2、s期增多,聯(lián)合用藥組出現(xiàn)s期增多;SKOV3/DDP細(xì)胞中,rhlL-24組處理出現(xiàn)G2期增多,聯(lián)合用藥組出現(xiàn)G1期增多。結(jié)論rhlL-24對(duì)卵巢癌細(xì)胞DDP敏感和耐藥株都具有抑制作用,聯(lián)合用藥可增強(qiáng)DDP的效應(yīng);rhlL-24對(duì)卵巢癌細(xì)胞的抑制作用通過誘導(dǎo)細(xì)胞凋亡實(shí)現(xiàn),rML-24處理細(xì)胞后周期變化出現(xiàn)G2期阻滯,聯(lián)合用藥組出現(xiàn)G1期阻滯。[關(guān)鍵詞
