1535-新一代3D癌症模型增强的依赖性图谱
from 聊聊Sci
这篇文章介绍了一项通过新一代三维（3D）癌症模型（如类器官和球状体）增强癌症依赖图谱（DepMap）的研究。研究团队对跨越10种癌症类型的147个模型进行了全基因组CRISPR筛选和多组学分析，弥补了传统细胞系在反映肿瘤亚型和培养环境方面的不足。通过对比发现，3D模型能更好地保留肿瘤特有的基因表达特征，从而揭示了在二维培养中被掩盖的生物标志物相关脆弱性。例如，研究确定了胶质母细胞瘤中与特定细胞状态相关的CDK6依赖性，以及消化道癌症中与粘蛋白分化程序相关的WNT信号通性依赖。该研究整合的数据集已通过DepMap门户网站公开，为精准肿瘤治疗提供了更具临床相关性的候选药物靶点资源。References:Neiswender J V, Maffa S, Brenan L, et al.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
