BACKGROUND
The most studied genetic polymorphisms associated with gastric cancer (GC) risk are located in protein-coding genes. However, the localization of these in long non-coding RNAs (lncRNAs) has not been fully studied. We aim to investigate the associations of Long non-coding RNA macrophage migration inhibitory factor antisense RNA1(Lnc-MIF-AS1) five polymorphisms (rs755622, rs17004044, rs2070767, rs1007889, rs2000468) with the risk and prognosis of GC.
METHODS
A total of 844 GC patients and 871 controls were included in the study. Genotyping was carried out using polymerase chain reaction-ligase detection reaction (PCR-LDR) technology. Odds ratios (ORs) and 95% confidence intervals (CIs) generated from unconditional logistic regression, were applied to quantify the effects of MIF-AS1 gene SNPs on GC risk. Log-rank test and Cox regression analysis were fitted to estimate hazard ratios (HRs) to quantify the effects of MIF-AS1 gene SNPs on GC prognosis.
RESULTS
Significant associations were identified between MIF-AS1 rs17004044 variants and GC group in the codominant, dominant and additive models (OR = 2.843, P = 0.010; OR = 1.370, P = 0.004; and OR = 1.386; P = 0.001). In addition, association between rs17004044 variants and survival of GC was extremely observed (TC HR = 2.02 (1.21-3.37) P = 0.007, CC HR = 5.61 (2.12-14.83), P = 0.001).
CONCLUSION
MIF-AS1 polymorphism rs17004044 contributes to increased predisposition and prognosis to GC.
背景
与胃癌（GC）风险相关的研究最多的基因多态性位于蛋白质编码基因中。然而，这些基因多态性在长链非编码RNA（lncRNA）中的定位尚未得到充分研究。我们旨在研究长链非编码RNA巨噬细胞迁移抑制因子反义RNA1（Lnc-MIF-AS1）的五个多态性（rs755622、rs17004044、rs2070767、rs1007889、rs2000468）与GC风险和预后的关系。
方法
本研究共纳入844例GC患者和871例对照。采用聚合酶链反应-连接酶检测反应（PCR-LDR）技术进行基因分型。应用无条件逻辑回归生成的优势比（OR）和95%置信区间（CI）来量化MIF-AS1基因单核苷酸多态性对GC风险的影响。采用对数秩检验和Cox回归分析来估计风险比（HR），以量化MIF-AS1基因单核苷酸多态性对GC预后的影响。
结果
在共显性、显性和加性模型中，MIF-AS1 rs17004044变异与GC组之间存在显著关联（OR = 2.843，P = 0.010；OR = 1.370，P = 0.004；OR = 1.386；P = 0.001）。此外，还观察到rs17004044变异与GC患者生存率之间存在关联（TC HR = 2.02（1.21 - 3.37），P = 0.007，CC HR = 5.61（2.12 - 14.83），P = 0.001）。
结论
MIF-AS1多态性rs17004044会增加GC的易感性和影响其预后。
