摘要:

目的:构建人NOB1基因的短发夹RNA(shRNA)慢病毒载体并在卵巢癌SKOV3和HEY细胞上定其沉默效率。 方法:针对NOB1基因设计特异性siRNA靶点,构建于慢病毒pLVTHM载体,筛选获得的有效shRNA慢病毒载体在293T细胞包装成病毒颗粒,随后将其感染卵巢癌SKOV3和HEY细胞,采用Real-time PCR方法检测靶基因在mRNA水平的沉默效率。 结果:构建的慢病毒载体shRNA的PCR鉴定和测序正确,包装病毒后滴度达到8×108 PU/L。shRNA慢病毒颗粒感染SKOV3和HEY细胞后NOB1基因的 mRNA表达量较阴性对照载体慢病毒感染组分别下降了73.5%和82.2%。 结论:成功构建NOB1基因的shRNA慢病毒表达载体,该慢病毒表达载体能够在细胞水平有效沉默靶基因。

Abstract:

Abstract:Objective  To construct the shRNA lentiviral vectors targeting human NOB1 gene and detect its effect of gene silence in SKOV3 and HEY cells.  Methods The specific siRNA sequences targeting human NOB1 gene were cloned into pLVTHM lentiviral vector. After screening for the valid siRNA,the lentivirus particles were packaged and NOB1 specific shRNA was transmitted into SKOV3 and HEY cells. Then,real-time PCR was performed to determine the expression level of NOB1.  Results  PCR and sequencing results revealed that shRNA plasmids were correctly constructed. The virus with a titer of 8×108 PU/L was successfully packaged.The  NOB1 expressions in SKOV3 and HEY cells were  down-regulated at mRNA level by virus infection. The expression levels of NOB1 mRNA was decreased by 73.5%  in SKOV3 and by 82.2% in HEY cells compared with negative control.
