466-弥漫大B细胞淋巴瘤的生物学变异轴

这份研究利用单细胞测序技术（RNA和ATAC测序）深入分析了弥漫性大B细胞淋巴瘤（DLBCL）的分子异质性。研究团队通过对103份活检样本的观测，成功为不同的遗传亚型绘制了独特的基因表达特征。调查发现，大多数肿瘤内部存在由拷贝数变异驱动的遗传亚克隆，这些克隆在细胞分化和生长代谢等方面表现出显著的表型差异。研究重点揭示了 REL基因扩增如何阻断记忆B细胞的末期分化，从而推动肿瘤发生。最终，这些发现建立了一套关联基因调控网络与临床预后的新模型，为提升化疗和靶向治疗的精准度提供了关键的生物学依据。References: Axes of biological variation in diffuse large B cell lymphomaWang, Boya et al.Cancer Cell, Volume 0, Issue 0前往小宇宙评论区与主播互动
