摘要 【目的】探讨适应性蛋白-1(adaptor protein containing PH domain-1,APPL1)对体外胃癌SGC-7901细胞增殖、侵袭的影响.【方法】胃癌SGC-7901细胞分为空白对照组(只转染试剂)、阴性对照组(转染APPL1阴性对照物,阴性组)、APPL1模拟物转染组(转染APPL1模拟物,模拟组)、APPL1抑制剂转染组(转染APPL1抑制剂,抑制组).采用荧光实时定量(PCR)法检测四组APPL1 mRNA表达,采用MTT法检测四组细胞增殖活力,采用T ransw ell小室法检测细胞侵袭力.【结果】转染后24 h、48 h、72 h,模拟组A P-PL1 mRNA表达均显著高于阴性组和空白对照组(P<0.05),抑制组APPL1 mRNA表达均显著低于阴性组和空白对照组(P<0.05),但阴性组和空白对照组比较差异无统计学意义(P>0.05).转染后24h、48h、72h,模拟组细胞增殖活力、穿膜细胞数均显著高于阴性组和空白对照组(P<0.05),抑制组细胞增殖活力、穿膜细胞数均显著低于阴性组和空白对照组(P<0.05).【结论】APPL1与胃癌的增殖、侵袭有密切关联,提高APPL1表达可增强胃癌的增殖、侵袭活性.
