J Cancer Res Clin:单羧酸转运蛋白基因多态性可影响结直肠癌患者临床预后

2014-12-09 MedSci译 MedSci原创

近日,第四军医大学肿瘤生物学国家重点实验室等处的研究者发现,单羧酸转运蛋白MCT1和MCT2基因多态性可影响结直肠癌患者临床结果,可用来预测术后结直肠癌患者对辅助化疗的反应性,最新研究成果在线发表于12月10日的J Cancer Res Clin杂志上。

先前的研究已证实单羧酸转运蛋白(monocarboxylate transporters,MCTs)在许多癌症发生和进展过程中发挥重要的作用。但其基因单核苷酸多态性(single-nucleotide polymorphisms ,SNPs)对结直肠癌(CRC)患者的预后价值还不是很清楚。近日,第四军医大学肿瘤生物学国家重点实验室等处的研究者发现,单羧酸转运蛋白MCT1和MCT2基因多态性可影响结直肠癌患者临床结果,可用来预测术后结直肠癌患者对辅助化疗的反应性,最新研究成果在线发表于12月10日的J Cancer Res Clin杂志上。这项研究共纳入697例中国结直肠癌术后患者,选取了3个单羧酸转运蛋白基因(MCT1,MCT2和MCT4)的9个功能性SNPs,并使用Sequenom iPLEX基因分型系统进行基因分型。研究还使用多元Cox比例风险模型和Kaplan–Meier曲线进行预后分析。研究结果显示,一个单核苷酸多态性(MCT1:rs1049434/exon)与结直肠癌患者总体生存期显著相关(HR 0.74;P=0.046)。另外两个单核苷酸多态性(MCT1:rs6084475
