1267-STIL在李-佛美尼综合征与骨肉瘤中的多组学研究

这项研究利用多组学分析和机器学习技术，揭示了STIL基因在李-佛美尼综合征（LFS）与骨肉瘤（OS）发病机制中的核心作用。研究发现，STIL能降低p53蛋白的稳定性，并根据TP53的状态表现出不同的致癌特性，尤其在基因突变背景下会显著增强肿瘤的干性、侵袭性和转移能力。通过单细胞测序，科学家证实STIL主要在具有高度恶性潜能的细胞群中表达，并通过激活特定的信号通路重塑肿瘤免疫微环境，从而帮助癌细胞实现免疫逃逸。实验进一步证明，干扰STIL的表达可抑制骨肉瘤细胞的生长，使STIL成为精准治疗中极具潜力的生物标志物和干预靶点。该研究不仅深化了对遗传性癌症易感性的分子理解，也为攻克耐药性骨肉瘤提供了新的药物敏感性参考。References:Qiao Y, Hao J, Yuan F, et al.

Forfeiture Book Review: Ecocide and Sci-Fi JP et al. A whizz bang review of the complex themes in the new ecological Sci-Fi novel, FORFEITURE by JP Nebra 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.
