Result 1 Magnetic nanoparticles, magnetic nanoparticles modified with antisense oligodeoxynucleotide of human telomerase reverse transcriptase induced HL-60 tumor cells to apoptosis, we could see typical morphologic change of apoptosis cells: karyopyknosis, chromation"s condensing and aggregation in nuclear, forming crescent-shaped or annulus structures to lean on edge of cell nucleus"s membrane and posing apoptosis body by Atomic Force Microscope, Fluorescence microscope, transmission electron Microscope 2 There was a significant difference compared with control group(p.01), inhibition ratio had significant positive correlation with medication dosage and time ;during 0.8-8μM dosage amplitude, inhibition ratio accrescenced by dosages increasing. However, the inhibition ratio would decrease when dosage over 8-80μM.

结果 1 磁性纳米粒子、修饰有端粒酶反义寡核苷酸的磁性纳米粒子诱导HL-60细胞发生凋亡，原子力显微镜、光学显微镜、荧光显微镜和透射电镜下均观察到HL-60细胞呈现典型的凋亡细胞的形态变化：细胞核固缩，核内染色质浓缩、凝聚、形成新月形或环状结构紧靠在细胞核膜边缘，并形成凋亡小体。2 磁性纳米粒子、修饰有端粒酶反义寡聚脱氧核苷酸的磁性纳米粒子对HL-60肿瘤细胞的生长和增殖有明显的抑制作用，与对照组相比有显著性差异(p＜0.01)，在剂量为0.8-8μmol／L范围内，抑制率随剂量的增加而增加，当剂量超过8μmol／L时，抑制率反而下降；3 磁性纳米粒子、修饰有端粒酶反义寡聚脱氧核苷酸的磁性纳米粒子可增强p53基因的表达活性，引起DNA降解损伤，反向调节细胞周期活动，促使细胞从G0期进入G1期，抑制肿瘤细胞的生长。4 修饰有端粒酶反义寡聚脱氧核苷酸的量子点能通过内吞作用进入HL-60肿瘤细胞的细胞核，可以在细胞内进行定位和促进HL-60肿瘤细胞的凋亡。
