摘要: 目的: 采用新型载体PEN对ODN进行传递,探讨MT01/PEN复合物对人成骨样细胞(MG63)细胞周期及成骨分化的影响。方法: 选取不同装载比例的MT01/PEN复合物,以MT01及S-MT01做对照,分别检测其对MG63细胞周期及成骨分化相关基因ALP活性、BMP2、OCN表达的影响。结果: MT01/PEN组Gl期、G2期细胞百分比降低,S期比例增高(P<0.01),碱性磷酸酶活性增加(P<0.01),OCN、BMP2蛋白表达增高(P<0.05)。结论: 以PEN为载体传递MT01能促进MG63的分化。

Abstract: Objective: To adopt a new vector PEN-loading ODN and evaluate its effects on the cell cycle and osteogenic differentiation of osteoblastic cells. Methods: Different ratios of MT01/PEN complex were transfected into MG63 cells, while MT01 and S-MT01 were negative controls. After that, the cell cycle, ALP activity, and the expression levels of BMP2 and OCN were detected. Results: In MT01/PEN group, cell percentages in Gl and G2 phase were decreased, while that in S phase was increased (P<0.01). Meanwhile, ALP activity was increased (P<0.01), and the expression of OCN and BMP2 were significantly up-regulated (P<0.05). Conclusion: The application of PEN as a carrier of ODN could promote the osteogenic differentiation of MG63 cells.
