1507-DANDELION：利用反式调控基因图谱优先确定哮喘疾病驱动因子
from 聊聊Sci
这篇文章介绍了一种名为DANDELION的新型统计计算框架，旨在从复杂的遗传网络中精准识别驱动疾病的关键基因。研究者通过整合跨通路调控信号与外显子组测序数据，成功筛选出直接参与病理过程的疾病近端基因，克服了传统研究往往只能发现次要关联基因的局限。以哮喘为应用实例，该研究通过 CRISPR 基因编辑技术和动物模型，证实了多个新候选基因对气道炎症和上皮屏障功能的调控作用。特别地，研究揭示了蛋白质棕榈酰化这一此前未被重视的生化途径在哮喘发病中的核心地位。该成果不仅深化了对多基因疾病遗传架构的理解，还为开发针对性的哮喘新型药物提供了极具潜力的治疗靶点。其发现的SLC27A3和SCD等关键酶，展现了通过调节脂质代谢干预免疫反应的临床前景。References:Salamone I M, Tian P, Qi Z, 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.
