Sci Rep:吉非替尼治疗的晚期肺腺癌中自噬核心基因变异的临床意义

2017-12-25 xiangting MedSci原创

自噬核心基因变异体在吉非替尼治疗中显示出潜在的临床意义,尤其是在晚期肺腺癌患者中。

EGFR-TKIs对伴活化EGFR突变的晚期肺腺癌患者有着显著的治疗益处。考虑到自噬在EGFR-TKIs治疗中的重要作用,研究人员假设自噬核心基因中的遗传变异可能会对用吉非替尼治疗的晚期肺腺癌患者的结局有影响。

研究人员系统检测了108例吉非替尼治疗的晚期肺腺癌患者的11种自噬核心基因,其中有27种潜在的功能性遗传多态性。发现ATG10 rs10036653,ATG12 rs26538,ATG16L1 rs2241880和ATG16L2 rs11235604与肺腺癌患者的生存率显著相关(P均?<0.05)。在EGFR突变患者中,ATG5 rs688810,ATG5 rs510432,ATG7 rs8154,ATG10 rs10036653,ATG12 rs26538,ATG16L1 rs2241880和ATG16L2 rs11235604对疾病预后有显著影响。此外还发现ATG5 rs510432,ATG5 rs688810,ATG10 rs10036653和ATG10 rs1864182与吉非替尼的原发性或获得性耐药有关。ATG10 rs10036653多态性的功能分析表明,在肺癌细胞中与T等位基因相比,ATG10 A等位基因增加转录因子OCT4的结合亲和力。

这项研究结果表明,自噬核心基因变异体在吉非替尼治疗中显示出潜在的临床意义,尤其是在晚期肺腺癌患者中,突出了基于种系和体细胞变异检测的EGFR-TKIs中为患者定制决策的可能性。
