摘要
目的 泛素特异性蛋白酶53(ubiquitin-specific protease 53,USP53)在结直肠癌(colon adenocarcinoma,COAD)中的临床意义和潜在机制尚不清楚。本研究采用生物信息学结合体外细胞学实验,观察USP53对结直肠癌细胞的抗癌作用。 方法 分析来自TCGA-COAD和GEO数据库(GSE39582数据集)的USP53表达数据。通过KEGG、GO和GSEA富集分析,探讨USP53可能参与的生物过程和信号通路。通过免疫浸润分析、药物敏感性分析结合CLUE平台和分子对接技术,预测潜在可用于治疗的小分子化合物。通过10种机器学习算法和101种集成组合构建预后预测模型,通过体外实验验证USP53的生物功能。 结果 USP53在COAD中具有抗肿瘤作用,低表达与较差的预后相关(P<0.05)。免疫浸润分析显示USP53低表达组有更高的免疫浸润水平,以及更高的TIDE和功能障碍评分(P<0.01)。体外实验表明,USP53过表达抑制了肿瘤细胞的增殖和迁移(P<0.05),并抑制了上皮-间质转化(epithelial-mesenchymal transition,EMT)。 结论 USP53通过影响EMT、凋亡、细胞周期调控和肿瘤免疫逃逸等机制发挥抗肿瘤作用,可能成为COAD的新型预后标志物。
