2、遷移、侵襲能力的影響;應(yīng)用流式細(xì)胞術(shù)分析其對(duì)細(xì)胞凋亡的作用。建立裸鼠MHCCLM3原位移植模型并觀察NC和/或索拉非尼對(duì)腫瘤大小和肺轉(zhuǎn)移率的影響。應(yīng)用RT-PCR、ELISA、Westernblot法檢測(cè)基質(zhì)金屬蛋白酶一9(matrixmetalloproteinase-9,牌9)、基質(zhì)金屬蛋白酶抑制劑一1(tissueinhibitorofmetalloproteinase-1,TIMP-1)、細(xì)胞外信號(hào)調(diào)節(jié)激酶1/2(ERK1/2)mRNA或相應(yīng)蛋白表達(dá)變化;并測(cè)定ERK1/2的磷酸化變化。結(jié)果NC與索拉非尼聯(lián)合應(yīng)用可顯著抑制HCC體外增殖和
