摘要 目的探讨载体介导的Survivin小干扰RNA(siRNA)对人结肠癌细胞株Lovo生物学行为的影响。方法构建Survivin特异性siR-NA真核表达载体。转染结肠癌癌细胞后,以噻唑蓝(MTT)比色法、克隆形成试验、流式细胞术测定细胞增殖、周期变化。结果与对照组相比,pGenesil-2-Survivin1和2载体干扰组增殖能力明显减弱(P<0.05);转染pGenesil-2-Survivin1和2质粒后14d,Lovo细胞形成克隆的百分率较正常组明显降低(P<0.05)。转染了pGenesil-2-Survivin1和pGenesil-2-Survivin2质粒后48h,Lovo细胞G0/G1和G2/M期细胞百分比较正常组明显增加(P<0.05),而S期细胞百分比较正常组明显减少(P<0.05)。结论载体介导的Survivinsi RNA对Survivin的抑制可显著抑制结肠癌细胞株Lovo的恶性生物学行为。
