ABCG 2、CD 133和CD 117是肿瘤干细胞的重要标志物,参与肿瘤的发生和发展。据报道,这些基因的表达与许多癌症的发生和进展相关,包括非小细胞肺癌(NSCLC)。我们在中国人群中的1001例NSCLC患者的临床队列中选择了3个基因中的9个潜在功能性单核苷酸多态性并进行了基因分型。我们发现ABCG 2 rs3114020变异基因型与NSCLC死亡风险显著增加相关(相加模型:校正风险比= 1.25,95%可信区间= 1.10-1.42,P< 0.001)。逐步回归分析提示rs3114020是影响NSCLC预后的独立危险因素。此外,在相互作用分析中,组织学与rs3114020对NSCLC生存的遗传效应相互作用。我们的研究结果表明,ABCG 2 rs3114020可能是中国人群中NSCLC生存的候选生物标志物之一,特别是在腺癌患者中。
ABCG2, CD133 and CD117 are pivotal markers of cancer stem cell, which are involved in carcinogenesis and cancer progression. The expression of these genes has been reported to be associated with the development and progression of many cancers, including non-small cell lung cancer (NSCLC). We selected and genotyped 9 potentially functional single-nucleotide polymorphisms in the 3 genes in a clinical cohort of 1001 NSCLC patients in a Chinese population. We found that variant genotypes of ABCG2 rs3114020 were associated with a significantly increased risk of death for NSCLC (additive model: adjusted hazard ratio= 1.25, 95% confidence intervals= 1.10–1.42, P< 0.001). Further stepwise regression analysis suggested that rs3114020 was an independent risk factor for the prognosis of NSCLC. Besides, histology interacted with the genetic effect of rs3114020 in relation to NSCLC survival in the interaction analysis. Our findings show that ABCG2 rs3114020 might be one of the candidate biomarkers for NSCLC survival in this Chinese population, especially among patients with adenocarcinoma.
