摘    要:目的 构建Survivin的shRNA表达质粒并将其导入白血病细胞株HL-60细胞以探讨PNA干扰对HL-60细胞增殖及凋亡的影响.方法 设计、合成两对针对survivin的shRNA序列,连接到带有人U6启动子的裁体质粒pSINsi-Hu6中,将构建重组质粒命名为pSIN/shRNA1和pSIN/shRNA2.pSIN/shRNA1转染HL60细胞,应用四唑盐(MTT)比色法观察细胞增殖情况;流式细胞仪检测细胞凋亡.结果 酶切分析和测序证实pSIN/shRNA1和pSIN/shRNA2构建成功.MTT测定显示转染重组质粒pSIN/shRNA1入HL-60细胞48、72和96 h后细胞增殖明显受到抑制,分别与阴性对照组、空白对照组组比较,差异有显著性(P<0.05).流式细胞仪分析pSIN/shRNA1组胞凋亡率达(20.21±0.75)%,明显高于阴性对照组的(2.58±0.48)%和空白对照组的(1.26±0.30)%.结论 成功地构建了survivin基因RNAi真核表达栽体,且pSIN/shRNA1可序列特异性地抑制HL-60细胞的增殖并诱导其凋亡,为白血病的基因治疗奠定基础.

Abstract:Objective To construct the short hairpin RNA (shRNA) expression vector of survivin and investigate its effect on the proliferation and the apoptosis of leukemia cell line HL-60. Methods Two pairs of oligonucleotide sequences targeted at human surviving mRNA were designed and synthesized. The annealed oligonucleotide fragments were subcloned into pSINsi-Hu6 plasmid. After being identified by restriction enzyme digestion and sequencing,the recombinant plasmid pSIN/shRNA1 were transfected into HL-60 cells. The...
Keywords:survivin gene  RNA interferenee  short hairpin RNA  leukemia  HL-60 eeU
