摘要:
目的 探讨长链非编码RNA（lncRNA）小核仁RNA宿主基因7（SNHG7）与胶质瘤生存预后的关系，及其对胶质瘤细胞侵袭和迁移的影响。方法 选取2015年6月至2016年3月手术切除的胶质瘤组织80例（术后随访截止2020年4月）和50例颅脑损伤颅内减压术中切取的非肿瘤脑组织为对照，用RT-PCR法检测lncRNA SNHG7的表达水平。体外培养胶质瘤U87细胞，转染不同质粒敲低lncRNA SNHG7表达，用Transwell实验检测细胞侵袭和迁移能力；双荧光素酶报告基因实验检测lncRNA SNHG7对miR-4516的调控作用。结果 胶质瘤组织lncRNA SNHG7表达量明显高于对照组（P<0.05）；多因素Cox回归分析显示，lncRNA SNHG7高表达是胶质瘤病人不良生存预后的独立影响因素（P<0.05）；生存曲线分析显示，高表达组胶质瘤病人中位总生存期较低表达组明显缩短（P<0.05）。敲低lncRNA SNHG7表达，明显抑制U87细胞侵袭和迁移力（P<0.05）。双荧光素酶报告基因实验证实lncRNA SNHG7靶向上调miR-4516表达，上调miR-4516可逆转敲低lncRNA SNHG7表达对胶质瘤U87细胞侵袭和迁移能力的作用（P<0.05）。结论 胶质瘤组织lncRNA SNHG7呈高表达，与病人不良生存预后有关。lncRNA SNHG7通过靶向调控上调miR-4516表达促进胶质瘤细胞的侵袭和迁移。
Abstract:
Objective To investigate the relationship between long non-coding RNA (lncRNA) small nucleolar RNA host gene 7 (SNHG7) and survival prognosis of glioma patients, and its effect on glioma cell invasion and migration. Methods The expression levels of lncRNA SNHG7 were detected by RT-PCR in glioma tissues obtained from 80 glioma patients who underwent surgery from June 2015 to March 2016 (postoperative follow-up ended in April 2020) and in non-tumor cerebral tissues obtained from 50 patients with traumatic brain injury (control group) during decompression. Glioma U87 cells were cultured in vitro, and the cells were transfected with different plasmids to knock down the expression of lncRNA SNHG7, and the ability of cell invasion and migration was detected by Transwell assay. The regulation of lncRNA SNHG7 on miR-4516 was verified by dual-luciferase reporter gene assay. Results The expression level of lncRNA SNHG7 in glioma tissues was significantly higher than that in the control group (P<0.05). Multivariate Cox regression analysis showed that the high expression of lncRNA SNHG7 was an independent risk factor for poor survival prognosis of glioma patients (P<0.05). Survival curve analysis showed that the median overall survival of glioma patients in the high expression group was significantly shorter than that in the low expression group (P<0.05). Knocking down the expression of lncRNA SNHG7 significantly inhibited the invasion and migration of U87 cells (P<0.05). The dual-luciferase reporter gene assay confirmed that lncRNA SNHG7 up-regulated miR-4516 expression, and up-regulation of miR-4516 could reverse the effect of knockdown of lncRNA SNHG7 expression on the invasion and migration of glioma U87 cells (P<0.05). Conclusions The high expression of lncRNA SNHG7 in glioma tissue is associated with poor survival prognosis of glioma patients. The lncRNA SNHG7 promotes the invasion and migration of glioma cells by up-regulation of miR-4516 expression.
