      摘 要:[目的] 通过病例对照设计来评估miR-15家族基因相关SNPs及其表达与食管鳞癌发生风险的关联。[方法] 从2017年10月至2018年6月于河南省林州市肿瘤医院就诊患者中,选取食管癌新发患者43例为病例组,选取同期在当地医院参加食管癌早诊早治筛查项目的59名健康人群为对照组。对miR-15家族(miR-15a、miR-15b、 miR-16、miR-195和miR-497)中miRNAs基因上的10个单核苷酸多态性(single nucleotide polymorphisms,SNPs)位点(rs1022960、rs10936201、rs11078662、rs14309、rs1451761、rs2066557、rs2740545、rs412999、rs7998223、rs9535416)与食管鳞癌发生风险进行关联研究。同时,对miR-16-5p在食管癌患者血清中的表达差异性进行测定。采用χ2检验比较各SNPs位点基因型在病例组和对照组的分布,用秩和检验分析两组间miR-16-5p表达水平的差异;对单因素分析有统计学差异的变量采用多因素的Logistic回归进行校正。[结果] 去除检测不合格的位点,最终纳入6个SNPs,各位点的基因型频率分布在病例组和对照组间差异均无统计学差异(P>0.05),食管鳞癌患者血清中miR-16-5p的表达量高于对照组(P<0.001)。[结论] miR-15家族中miR-16在食管鳞癌患者血清中高表达,但未发现候选的miRNAs多态位点与食管鳞癌发生风险相关。
英文摘要:
      Abstract:[Purpose] To evaluate the association between single nucleotide polymorphisms(SNPs) of miR-15 family and the risk of esophageal squamous cell carcinoma(ESCC). [Methods] Forty three ESCC patients admitted in Linzhou Cancer Hospital and 59 healthy subjects were recruited from October 2017 to June 2018. Genotypes were determined by MassArray based on allele-specific MALDI-TOF mass spectrometry. The expression level of miR-16-5p was detected by quantitative real-time PCR(qRT-PCR). The distribution of genotypes of each SNP was analyzed by χ2 test;Mann-Whitney U test was used to compare the expression change of miR-16-5p;the variables with statistical differences in univariate analysis were adjusted by multivariate logistic regression. [Results] After removing the unqualified SNPs,the genotype distribution of 6 SNPs included in the analysis was not associated with ESCC susceptibility(P>0.05). However,the expression level of the serum miR-16-5p in ESCC patients was significantly higher than that in healthy controls(P<0.001). [Conclusion] The polymorphisms in miR-15 family may be not associated with the risk of ESCC,but the expression of serum miR-16 is significantly upregulated in ESCC patients.
