Abstract

Background: There are still gaps in the study of the miRNA and its SNPs in some diseases such as non-small cell lung cancer (NSCLC). The study aimed to provide useful information on the treatment of NSCLC by investigating the association between miR-21 and its SNPs and NSCLC susceptibility.

Methods: The serum of NSCLC patients (n = 205) and cancer-free controls (n = 217) were collected in this study for RNA extraction. The qRT-PCR was used to evaluate the expression of miR-21 and Taqman qPCR was used for genotyping and quantifying miR-21 SNPs (rs1292037, rs6504593). The association of the expression of miR-21, the miR-21 SNPs and their interactions with the susceptibility of NSCLC patients were analysed using logistic regression analysis in this study.

Results: This study showed that the overexpression of miR-21 was related to NSCLC. The C allele and CC genotypes of rs1292037 and rs6504593 were associated with the increased risk of NSCLC susceptibility. Moreover, the interactions of rs1292037 and rs6504593 were also a risk factor for NSCLC. The CC genotypes of rs1292037 and rs6504593 were associated with the increase of miR-21 expression.

Conclusion: The overexpression of miR-21, the miR-21 SNPs rs1292037 and rs6504593 and their interactions were associated with NSCLC susceptibility. MiR-21 and its SNPs have potential for being targets in the therapy of NSCLC. This study provided important information for the treatment of NSCLC.

miR-21单核苷酸多态性与非小细胞肺癌易感性的相关性

背景：非小细胞肺癌（NSCLC）等疾病中miRNA及其snp的研究仍存在空白。该研究旨在通过研究miR-21及其snp与NSCLC易感性之间的关系，为NSCLC的治疗提供有用的信息。方法：采集非小细胞肺癌（NSCLC）患者（205例）和无癌对照组（217例）的血清进行RNA提取。采用qRT-PCR检测miR-21的表达，采用Taqman qPCR对miR-21 snp （rs1292037, rs6504593）进行基因分型和定量。本研究采用logistic回归分析miR-21表达、miR-21 snp及其相互作用与NSCLC患者易感性的关系。结果：本研究显示miR-21过表达与NSCLC相关。rs1292037和rs6504593的C等位基因和CC基因型与NSCLC易感风险增加相关。此外，rs1292037和rs6504593的相互作用也是NSCLC的危险因素。rs1292037和rs6504593的CC基因型与miR-21表达升高相关。结论：miR-21、miR-21 snp rs1292037和rs6504593的过表达及其相互作用与NSCLC易感性相关。MiR-21及其snp具有成为非小细胞肺癌治疗靶点的潜力。本研究为非小细胞肺癌的治疗提供了重要信息。
