摘要: 目的探讨同源异型盒基因B1(HOXB1)与微小RNA3175(miR3175)在人胶质瘤中表达的关系及临床意义。方法通过实时荧光定量PCR(qRTPCR)检测60例人胶质瘤组织和15例正常脑组织中HOXB1与miR3175的表达,采用Spearman相关分析法分析人胶质瘤组织中HOXB1、miR3175表达的相关性,分析HOXB1、miR3175表达与临床病理特征的关系,采用KaplanMeier评估HOXB1、miR3175与患者生存期的关系,采用COX回归模型分析患者预后因素。结果较正常脑组织,HOXB1在人胶质瘤组织中低表达(1.498±0.323∶0.946±0.588,t=-5.680,P=0.000),miR3175在人胶质瘤组织中高表达(1.008±0.355∶2.076±0.841,t=4.274,P=0.000),并且在人胶质瘤组织中HOXB1与miR3175表达呈负相关(r=-0.601,P=0.000)。HOXB1表达与肿瘤分级相关(χ2=4.848,P=0.028),miR3175表达与肿瘤分级(χ2=5.640,P=0.018)、Karnofsky功能状态评分(χ2=4.785,P=0.029)相关。KaplanMeier分析结果显示HOXB1、miR3175高表达组与低表达组中位生存期[HOXB1:(21.0±4.0)个月∶(7.0±0.8)个月;miR3175: (6.0±0.6)个月∶(16.0±5.8)个月]差异有统计学意义(χ2=7.495,P=0.006;χ2=9.591,P=0.002)。COX回归模型分析结果显示肿瘤分级(RR=6.556, 95%CI为1.196~35.952,P=0.002)、HOXB1(RR=0.018,95%CI为0.001~0.312,P=0.006)和miR3175(RR=2.098,95%CI为1.663~7.513,P=0.037)是影响胶质瘤患者预后的独立因素。结论HOXB1与miR3175在人胶质瘤中的表达呈负相关,并与胶质瘤组织的恶性程度、胶质瘤患者的生存期及预后密切相关。

Abstract: ObjectiveTo explore the relationship and the clinical significance of homeobox gene B1 (HOXB1) and microRNA3175 (miR3175) expressions in human glioma. MethodsThe expression levels of HOXB1 and miR3175 in 60 glioma tissues and 15 normal brain tissues were analyzed by realtime fluorescent quantitative PCR (qRTPCR). Spearman rank correlation analysis was performed to explore the relationship between HOXB1 and miR3175 in human glioma tissues. The relationship between HOXB1 (or miR3175) and clinical pathological characteristics of glioma patients was analyzed. The correlation of HOXB1 (or miR3175) and survival rate was calculated by KaplanMeier. And COX regression models were used to assess the prognostic factors. ResultsCompared with normal brain tissues, the expression of HOXB1 was significantly decreased in glioma tissues (1.498±0.323 vs. 0.946±0.588, t=-5.680, P=0.000); and the expression of miR3175 was obviously increased in glioma tissues (1.008±0.355 vs. 2.076±0.841, t=4.274, P=0.000), and HOXB1 expression was negatively correlated with miR3175 expression in glioma tissues (r=-0.601, P=0.000). HOXB1 expression was related with histologic grade (χ2=4.848, P=0.028), and miR3175 expression was related with histologic grade (χ2=5.640, P=0.018) and Karnofsky score (χ2=4.785, P=0.029). The results of KaplanMeier revealed that there were significant differences in median survival time between HOXB1 (or miR3175) highexpression group and HOXB1 (or miR3175) lowexpression group [HOXB1: (21.0±4.0)months vs. (7.0±0.8) months; χ2=7.495, P=0.006; miR3175: (6.0±0.6) months vs. (16.0±5.8) months; χ2=9.591, P=0.002]. COX regression models showed that tumor degree (RR=6.556, 95%CI: 1.19635.952, P=0.002), HOXB1 (RR=0.018, 95%CI: 0.0010.312, P=0.006) and miR3175 (RR=2.098, 95%CI: 1.6637.513, P=0.037) were independent prognostic factors for prognosis. ConclusionThe HOXB1 expression may be negatively correlated with miR3175 in human glioma tissues, and the expression levels of HOXB1 and miR3175 are associated with the glioma malignant degree, survival time and prognosis of glioma patients.
