		     | 目的探讨长链非编码RNA(LncRNA)浆细胞瘤转化迁移基因1(PVT1)在神经胶质瘤中的表达及临床意义。方法采用qRT-PCR方法检测并比较53例神经胶质瘤组织(观察组)及6例正常脑组织(对照组)中LncRNAPVT1的表达量。根据神经胶质瘤组织中LncRNAPVT1的中位表达量分为高表达组与低表达组,分析LncRNAPVT1表达量与临床病理因素的关系。采用Kaplan-Meier法绘制不同LncRNAPVT1表达量的神经胶质瘤患者生存曲线,并分析LncRNAPVT1表达量与神经胶质瘤患者预后的关系。结果观察组LncRNAPVT1的表达量明显高于对照组(P<0.01)。其中高级别胶质瘤(WHOⅢ~Ⅳ级)的LncRNAPVT1表达量明显高于低级别胶质瘤(WHOⅠ~Ⅱ级)(P<0.01)。LncRNAPVT1表达量与神经胶质瘤WHO分级密切相关(P<0.01),与患者年龄、性别、Karnofsky功能状态评分(KPS)评分、肿瘤大小等均无关(均P>0.05)。经log-rank检验,高表达组患者预后较低表达组差,差异有统计学意义(P<0.01)。结论LncRNAPVT1在神经胶质瘤组织中高表达,表达量与神经胶质瘤WHO分级及患者预后密切相关;LncRNAPVT1可能成为判断神经胶质瘤恶性程度及预后的新型分子标记物。 |

                | Objective To investigate the expression of long-coding RNA (lncRNA) of plasmacytoma variant translocation gene 1  (PVT1) in glioma and its clinical significance.   Methods    qRT-PCR was applied to detect the expression of lncRNA PVT1 in 53 specimens of glioma (glioma group) and 6 specimens of normal brain tissues (control group). The survival curves were generated with Kaplan-Meier method. The correlation between the expression of lncRNA PVT1 and clinicopathological    features,
prognosis of patients was analyzed. Results The expression of lncRNA PVT1 was significantly up-regulated in glioma group compared with that the control group (P<0.01). The expression of lncRNA PVT1 in high-grade neuroglioma (WHO III-IVgrade) was significantly higher than that in low-grade neuroglioma (WHO I-II grade) (P<0.01). The expression of lncRNA PVT1 was significantly associated with the WHO grading of glioma (P<0.01), but not with age, gender, Karnofsky Performance Status (KPS) score and tumor size (All P >0.05). Log-rank test revealed that patients with high expression of lncRNA PVT1 was significantly associated with worse prognosis compared with those with low expression(P<0.01).    Conclusion    LncRNA PVT1 is up-regulated
in neuroglioma tissues. The expression of lncRNA PVT1 is closely associated with WHO grading system and prognosis of patients, indicating that lncRNA PVT1 may serve as a novel molecular biomarker for determination of the malignant degree and prognosis of neuroglioma. |
