摘要 目的在肿瘤类器官中研究阻断Wnt信号治疗结直肠癌的价值。方法从在衡水市第四人民医院就诊的结直肠癌患者中遴选120名适合患者,从患者的手术标本收集癌组织、癌旁组织,然后利用类器官培养技术进行体外3D建模,选择Porcupine蛋白(PROCN)抑制剂LGK974进行药物处理,测定癌组织和癌旁组织WntmRNA的表达水平,研究LGK974药物干预Wnt通路靶点后对结直肠癌肿瘤成瘤性的影响。结果实验中采取半定量PCR方法对比癌旁组织和癌组织中Wnt表达水平,我们发现在LGK974抑制剂后,癌旁组织WntmRNA表达水平(1.17±0.04),癌组织中WntmRNA表达水平(2.83±0.19),经对比其差异具有统计学意义(P<0.05)。结论通过本次研究证实,Wnt信号通路的激活与结直肠癌发生密切相关,LGK974药物对结直肠癌肿瘤有明显抑制作用,肿瘤类器官对于寻找抗癌药物具有十分重要的研究价值。
