初级纤毛对人牙周膜细胞成骨相关基因表达的影响
|
Abstract:
摘要 目的:通过沉默纤毛运输蛋白88(intraflagellar transport 88,IFT88)基因抑制人牙周膜细胞(human periodontal ligament cells, hPDLCs)中初级纤毛的形成,进一步研究其对hPDLCs成骨相关基因表达的影响。方法:实验分为对照组和shIFT88组。对照组感染无意序列,shIFT88组感染含IFT88基因有效短发卡RNA(short hairpin RNA,shRNA)的慢病毒。qRT-PCR、Western blot检测各组细胞中IFT88表达情况,免疫荧光检测初级纤毛形成, qRT-PCR检测成骨相关基因COL1A1,OCN,Runx2,BMP2表达量的变化。结果:与对照组相比,shIFT88组IFT88表达量明显下调(P<0.01),纤毛率降低(P<0.01),成骨相关基因COL1A,OCN,Runx2,BMP2基础表达量明显下调(P<0.01)。结论:沉默IFT88基因后,hPDLCs初级纤毛形成受阻,成骨相关基因表达量明显下调
