RNAi技术沉默大鼠骨髓间充质干细胞OPG基因对RANKL/OPG表达变化研究
|
Abstract:
摘要 目的: 探讨RNAi技术体外沉默大鼠骨髓间充质干细胞(BMSCs)OPG基因提高RANKL/OPG比例的可行性。方法: 设立空载组(空慢病毒载体转染BMSCs)和OPG沉默组(含OPG基因干扰片段的慢病毒载体转染BMSCs),RT-PCR检测OPG及RANKL的mRNA表达变化,Western blot检测OPG及RANKL的蛋白表达变化。结果: 与空载组比较,OPG沉默组OPG的mRNA和蛋白表达显著降低,RANKL的mRNA表达显著升高,差异均有统计学意义(P<0.05);两组RANKL的蛋白表达差异无统计学意义(P>0.05);OPG沉默组RANKL/OPG mRNA和蛋白表达比例均显著升高,差异均有统计学意义(P<0.05)。结论: 以慢病毒为载体,通过RNAi技术体外沉默大鼠骨髓间质干细胞OPG基因提高RANKL/OPG比例的方法是可行的
