2、對C13K細(xì)胞體外增殖、凋亡及裸鼠移植瘤生長的影響為卵巢癌的靶向治療尋找新的藥物。方法C13K細(xì)胞經(jīng)PI一103和/或順鉑處理后,以MTr法檢測細(xì)胞的增殖情況,以流式細(xì)胞儀檢測細(xì)胞凋亡,Western印跡檢測p-AKT和p-S6K1的表達(dá)情況。建立C13K細(xì)胞皮下裸鼠移植瘤模型,隨機(jī)分成對照組、PI一103組、順鉑組、合并組4組,連續(xù)用藥4周。觀察腫瘤生長情況,計(jì)算抑瘤率。結(jié)果PI一103聯(lián)合順鉑抑制C13K細(xì)胞增殖,且隨時(shí)間延長抑制作用越顯著,抑制效果優(yōu)于單獨(dú)用藥。PI一103可增強(qiáng)順鉑在CI3K
3、細(xì)胞中引起的凋亡。經(jīng)PI103作用后的C13K細(xì)胞表達(dá)p-AKT和P—S6K1較對照組下降,PI一103聯(lián)合順鉑明顯抑制裸鼠C13K細(xì)胞皮下移植瘤的生長,較順鉑單藥組有明顯差異性。結(jié)論P(yáng)I一103增強(qiáng)順鉑對CI3K細(xì)胞裸鼠移植瘤生長的抑制作用?!娟P(guān)鍵詞】PI103;順鉑;C13K細(xì)胞;裸鼠;PI3K【中圖分類號】R73-3PI.1O3EnhancesCisplatin—CausedGrowthInhibitionofC13KCellXenograftsinNudeMiceLIUYong一,KONGF
