1242-人类卵巢衰老的时空转录组特征与FOXP1的调控作用
from 聊聊Sci
这项研究通过单细胞转录组测序与空间转录组技术，首次系统地描绘了人类卵巢衰老的时空分子图谱。研究团队分析了从青年到绝经期不同阶段的卵巢样本，识别出八种主要细胞类型及其在衰老过程中的基因表达演变。研究重点揭示了卵母细胞中DNA损伤修复能力的下降，以及颗粒细胞不同亚型的空间分布特征与功能衰退。此外，该研究鉴定出关键调控因子FOXP1在维持卵巢年轻化中的核心作用，发现其表达量随年龄增长而减少，进而诱发细胞衰老。这些发现为理解女性生殖衰老提供了精确的分子框架，并为开发卵巢早衰的诊断标志物及临床治疗方案奠定了理论基础。References:Wu M, Tang W, Chen Y, 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.
