方法 利用大剂量冲击联合低剂量诱导的方法建立对安罗替尼耐药的肝癌细胞,用CCK8实验进行验证耐药细胞在安罗替尼作用下的细胞增殖差异;运用ceRNA芯片检测耐药肝癌细胞与正常肝癌细胞的基因表达差异;运用实时荧光定量PCR(real-timePCR)对部分芯片测出的部分基因差异进行验证。
计量资料两组间比较采用独立样本t检验,Kaplan-Meier法对肝癌样本的总生存期进行生存分析,log-rank检验比较生存率差异。
芯片筛选结果使用Fisher精确检验。
结果 耐药肝癌细胞与正常肝癌细胞基因表达差异较大,通过缩减范围筛选出差异最大的10个基因进行分析。
与耐药和肿瘤生长相关的基因有4个,分别为BIRC2、BIRC7、ABCC2、MAPK8。
其中BIRC2、ABCC2、MAPK8表达水平下降(P值分别为0.0014、0.0012、0.0118),BIRC7的表达水平增多(P<0.001)。
real-timePCR的验证结论与芯片一致(t值分别为10 74、32 65、18 34、2 80,P值分别为0.0004、0.0001、0.0001、0.0448)。
BIRC7的高表达与MAPK8的低表达对应显著减少的生存期(P值分别0.0220、0.0056)。
结论 BIRC2、BIRC7、ABCC2、MAPK8在对安罗替尼耐药的肝癌细胞中差异表达,可能参与了肝癌细胞对安罗替尼耐药的过程。
