目的探讨同时下调长链非编码RNA(lncRNA)人浆细胞瘤转化迁移基因1(PVT1)和MINCR(MYC-induced long non-coding RNA)对淋巴瘤细胞株Raji增殖的影响及其可能机制。方法合成靶向PVT1、MINCR的小干扰RNA(siRNA)和无关对照siRNA(SC-siRNA)序列。实验分为PVT1-siRNA组、MINCR-siRNA组、PVT1-siRNA+MINCR-siRNA组、无关对照组和细胞组(未转染的Raji细胞)。将各条siRNA转入Raji细胞后,用实时定量RT-PCR方法检测MINCR RNA表达水平;分别用CCK8法、流式细胞仪、Western blot检测细胞增殖、细胞周期和c-Myc蛋白的表达情况。结果转染MINCR-siRNA后MINCR表达下调,与无关对照组和细胞组相比差异有统计学差异(P<0.05)。PVT1-siRNA联合MINCR-siRNA转染到Raji细胞后,细胞增殖明显受到抑制(P<0.05),细胞周期阻滞于G1期(P<0.05),c-Myc蛋白表达下降(P<0.05),且与单用PVT1-siRNA组、MINCR-siRNA组相比差异均具...
【英文摘要】
Objective To study the influence of down-regulating long non-coding RNA( lncRNA) plasmacytoma variant translocation 1( PVT1) and MYC-induced long noncoding RNA( MINCR) on the proliferation of lymphoma cells Raji and the probable mechanism. Methods Small interfering RNA( siRNA) targeting against PVT1 and MINCR as well as scramble control siRNA( SC-siRNA) were designed and synthesized chemically. The experiment was divided into PVT1-siRNA group,MINCR-siRNA group,PVT1-siRNA + MINCR-siRNA group,scramble control...
