L1细胞粘附分子胃癌临床意义生物学作用

由此可见，L1CAM可能是确定高GC复发风险患者的可行生物标志物。

L1细胞粘附分子（L1CAM）在恶性肿瘤中高表达，并可能在肿瘤进展中起关键作用。

近日，肿瘤领域权威杂志British Journal of Cancer上发表了一篇研究文章，研究人员通过免疫组化分析了309例胃癌（GC）患者福尔马林固定、石蜡包埋的标本中L1CAM蛋白的表达。研究人员进行了倾向得分匹配（PSM）分析，以阐明L1CAM对GC患者的预后的影响。研究人员评估了另一组131名GC患者新鲜冰冻标本中的L1CAM基因表达，以确定其临床相关性。并在体内和体外实验中探究了L1CAM变化的影响。 

L1CAM主要在GC组织的肿瘤细胞中表达。L1CAM表达升高是GC患者总体生存和无病生存的独立预后因素，也是远处转移的独立危险因素。PSM分析显示，L1CAM高表达与不良预后显著相关。在独立的队列中使用新鲜的冷冻标本进行的L1CAM基因表达成功验证了所有这些发现。体外实验中，抑制L1CAM可显著抑制GC细胞的增殖、循环进程、侵袭、迁移和无神经碱抗性。此外，抑制L1CAM可显著抑制腹膜转移瘤的生长。

由此可见，L1CAM可能是确定高GC复发风险患者的可行生物标志物。
