METHODS: SGC7901 cells were transfected with siRNAs targeted against the human PLK1 by chemosynthesis. The PLK1 mRNA levels of cells transfected with siRNAs were monitored by real time PCR and the protein levels were detected by immunocytochemistry. Cell proliferation was evaluated by direct cell counting with trypan blue staining.

On the termination date, the cultured explants were all examined by Western blot, HE and transmission electron microscope. Our results showed that after 12-days in culture, the cultivation treated with AS-ODN reduced the synthesis of AMBN and had a deformed dental cusp with thinner enamel matrix. Ultrastructure analyses showed that there was hardly any cisternae of the rough endoplasmic reticulum in the ameloblasts at the tip of the cusp of AS-ODN treatedexplants. However, on average the enamel matrix was thinner compared with that in the control group. Furthermore, the collagen fibers in extracellular matrix were found disorganized. These findings seemed to provide a direct experimental evidence that tended to indicate that the arrested AMBN translation in cultured tooth germs might result in the delay of the tooth development.

经用Western蛋白印迹检测表明，所设计的反义核酸对AMBN InRNA具有良好的封闭效果并成功阻断了牙胚对AMBN的表达；在缺乏AMBN情况下，与对照组相比，实验组牙胚在体外可以继续生长发育至钟状晚期，出现成釉细胞和成牙本质细胞的分化，成釉细胞可以分化成为分泌期型成釉细胞，胞浆中缺少合成蛋白质所必需的粗面内质网和高尔基氏体，缺乏溶酶体，表明对蛋白合成和脚的能力降低；实验组牙胚有牙尖形成和基质分泌，但牙尖形态异常，基质形成减少，牙尖周围基质最厚处为O.6卜m，明显薄于对照组的5.spin，基质中胶原纤维粗细不等，排列稀疏， 3 第四军医大学硕士学位论文未见钙化现象，充分证明了AMBN在牙胚发育中参与釉质基质形成和矿化过程，影响胶原纤维和牙本质基质的合成，促进成釉细胞对蛋白质的合成和釉质基质蛋白降解。

METHODS: Spleen cells of 1, 2, 4, 6, 8, 10, 12, 16, 20 and 24 h in the coculture system were observed and the expression of RNA editase was detected by semiquantitative PCR and was contrasted with the mouse spleen cells in a singleculture system. The mouse model with the immune system restrained by FK506 was made, its spleen cells were cocultured with stimulated cells and then the effect of FK506 on RNA expression of editase was detected by semiquantitative PCR.
