1、基礎(chǔ)醫(yī)學(xué)·2014年5月第4卷第1O期不同濃度依托咪酯誘導(dǎo)人肝癌HepG2細(xì)胞體外凋亡的研究王泓源曹定睿馬曉燕連梓敏山西醫(yī)科大學(xué)第一醫(yī)院麻醉科,山西太原030001【摘要]目的探討不同濃度的依托咪酯是否具有直接誘導(dǎo)人肝癌HepG2細(xì)胞凋亡的作用,尋找依托咪酯臨床治療的新途徑。方法人肝癌細(xì)胞株HepG2體外擴(kuò)增培養(yǎng)備用,選取不同濃度的依托咪酯E1、E2、E3和對照組(空白),分別培養(yǎng)12h、24h、48h后觀察。結(jié)果與空白對照組相比,培養(yǎng)12h、24h、48h后E1組、E2組人肝癌細(xì)胞株HepG2細(xì)胞凋亡率
2、無明顯差異(P>0.05),E3組凋亡率不斷增加,具有顯著性差異(P<0.05);隨著培養(yǎng)時間的延長及濃度的不斷增加,E1與E2組對比人肝癌細(xì)胞株HepG2細(xì)胞凋亡率無明顯差異(f:1.732,P>0.05),E1與E3組對比人肝癌細(xì)胞株HepG2細(xì)胞凋亡率具有顯著性差異(t=1.864,P<0.05),E2與E3組對比人肝癌細(xì)胞株HepG2細(xì)胞凋亡率具有明顯差異(t=1.691,尸<0.05)。結(jié)論依托咪酯在臨床安全有效的濃度下不直接誘導(dǎo)人肝癌HepG2細(xì)胞的體外凋亡,濃度及時間達(dá)到一定峰值時可具有直接
