1173-弥漫性大B细胞淋巴瘤蛋白质基因分型的发病机制研究

这项研究通过整合蛋白质组学、转录组学和基因组学数据，对478例弥漫性大B细胞淋巴瘤（DLBCL）样本进行了多维分析。研究人员利用MuVI机器学习方法识别出七种具有独特分子特征和临床预后的蛋白质基因型（Proteogenotypes, PGs）。其中，PG4被定义为一种高风险亚型，其特征是MYC、TCF3/4活性增强及B细胞受体信号活跃，且伴随T细胞功能耗竭。由于该亚型在接受R-CHOP标准方案治疗后预后极差，研究为其提供了独立于传统遗传亚型的生物标志物。该研究揭示了蛋白质层面对理解肿瘤异质性的重要性，并为开发针对性诊断和免疫治疗策略提供了新的科学框架。References:Enssle J C, Häupl B, Qoku A, et al.
