871-利用scFOCAL框架识别胶质母细胞瘤耐药细胞群与协同疗法

from 聊聊Sci

这项研究介绍了 scFOCAL,这是一个将单细胞 RNA 测序数据与 LINCS L1000 药物反应图谱相结合的新型计算框架,旨在解决胶质母细胞瘤 (GBM) 的治疗耐药性问题。研究人员通过分析肿瘤内的转录异质性,成功预测了不同细胞状态对特定药物的敏感性与耐药性。利用该工具,团队发现 NPC 样细胞对极光激酶抑制剂 alisertib 敏感,而 MES 样细胞则表现出抗性,并在体内实验中验证了这种转录状态的转变。此外,scFOCAL 提出了一种联合用药索引,据此确定了 OLIG2 抑制剂 (CT-179) 与 EGFR 抗体偶联药物 (Depatux-M) 的协同组合,显著延长了患癌小鼠的生存期。该成果不仅揭示了精准打击特定肿瘤细胞群体的潜力,还通过发布开源 R 软件包和 Web 应用程序,为个性化医疗和新药组合开发提供了可访问的分析平台。References: Suter R K, Jermakowicz A M, Veeramachaneni R, et al.
