摘　　要：目的　探讨同源盒基因B2 (HOXB2 )反义硫代寡核苷酸对脐静脉内皮细胞增殖、表达的影响。　方法　以脂质体介导将硫代磷酸修饰的同源盒基因HOXB2反义寡核苷酸转染入脐静脉内皮细胞 ,采用MTT和RT PCR观察不同浓度反义寡核苷酸对内皮细胞增殖及HOXB2mRNA表达水平的影响。　结果　经脂质体介导的HOXB2反义寡核苷酸转染 ,内皮细胞增殖受到抑制并呈剂量依赖效应 ,同时HOXB2mRNA表达水平显著下降。　结论　HOXB2在内皮细胞的增殖中起重要作用 。Objective To explore the effects of HOXB2 anti-sense oligodeoxynucleotides (asodn) on the proliferation and the expression of human umbilical vein endothelial cells (HUVECs). Methods Various concentrations of HOXB2 ASODN modified by thiophosphate were transfected into HUVECs by liposome mediation. MTT and RT-PCR methods were employed to determine the influence of different concentrations of ASODN on endothelial proliferation and the expression level of HOXB2 mRNA. Results After the transfection of HOXB2 ASODN, the endothelial proliferation was inhibited in dose-dependent manner. Simultaneously, the expression level of HOXB2 mRNA decreased significantly. Conclusion HOXB2 might play important roles in the proliferation of endothelial cells.
