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.
