469-髓母细胞瘤多组学分析揭示MYC驱动的脂质依赖性
from 聊聊Sci
这项研究通过对384个临床样本进行多组学整合分析，揭示了3型髓母细胞瘤（Group 3 MB）内部显著的代谢异质性。研究人员发现了一种被称为G3p_a的高危蛋白质组亚型，该亚型与MYC癌基因的高表达密切相关，并表现出极差的预后。实验证明，MYC通过促进从头脂质合成与增强脂质摄取，导致肿瘤细胞内脂质滴的大量积聚。这种特殊的脂质依赖性转化为了治疗弱点，特别是针对DGAT1酶的抑制能显著干扰脂质稳态。研究结论指出，靶向脂质代谢通路不仅能延缓肿瘤生长，还为治疗这种极具侵袭性的儿童脑瘤提供了全新的策略。References: Bernardi F, Torrejon J, Basili I, 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.
