摘要 目的观察β-catenin、磷酸化GSK-3β、c-myc在大肠侧向发育型肿瘤和隆起型腺瘤中的表达情况,探讨两种大肠肿瘤类型之间的差异。方法收集50例大肠侧向发育型肿瘤和54例大肠隆起型腺瘤的活检标本,统计其临床病理学资料,采用免疫组化检测各标本中β-catenin、磷酸化GSK-3β、c-myc蛋白的表达情况。结果β-catenin,磷酸化GSK-3β,c-myc在侧向发育型肿瘤中的表达明显强于在隆起型腺瘤中的表达(P<0.05),且不受患者年龄的影响。结论 Wnt/β-catenin信号通路在大肠侧向发育型肿瘤中的活动显著强于在隆起型腺瘤中的活动,GSK-3β的磷酸化失活可能与大肠侧向发育型肿瘤中β-catenin的活化有关。
