812-雄激素驱动的PFA室管膜瘤机制研究
from 聊聊Sci
这项研究揭示了雄激素信号是导致PFA型室管膜瘤（一种致命的幼儿脑肿瘤）在男性中发病率更高且预后更差的核心驱动因素。通过对比人类患者与小鼠模型的单细胞转录组数据，研究人员发现男性肿瘤细胞表现出更强的干细胞特性，且分化程度明显低于女性。研究进一步利用四核心基因型小鼠模型证实，这种发育迟缓是由性激素而非性染色体决定的。实验结果显示，补充雄激素会加速肿瘤生长，而阻断雄激素则能显著抑制肿瘤细胞的增殖并增强其分化潜能。这一发现为这种目前缺乏有效化疗手段的儿童癌症指明了抗雄激素疗法这一潜在的临床治疗方向。References: Zhang J, Ong W, Rasnitsyn A, 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.
