1444-乳腺癌脑转移的单细胞图谱研究

from 聊聊Sci

这份研究通过单细胞多组学技术深入探讨了乳腺癌脑转移(BCBM)的分子机制。研究团队分析了13万余个细胞,识别出12种肿瘤相关巨噬细胞(TAM)亚型和5种转移性肿瘤细胞(MTC)亚型,揭示了免疫微环境与癌细胞之间的动态演化。研究发现,转移后的肿瘤细胞会通过神经拟态适应脑部环境,且脑转移灶表现出比原发灶更高的突变负荷。关键基因GABRB3和NRXN1被鉴定为调控脑转移的关键因子,其高表达与患者生存率下降密切相关。实验进一步证实,敲除这些基因能显著抑制肿瘤的生长、迁移及脑部定植,为临床提供了潜在的诊断生物标志物和治疗靶点。References:Shi H, Chen J, Wu Z, et al.
