1583-膀胱癌中L1逆转录转座与基因组不稳定性研究
from 聊聊Sci
这项研究通过对48名膀胱癌患者进行多组学整合分析，揭示了驱动癌症进展的复杂分子机制。研究利用长读段测序和空间转录组学技术，首次在临床样本中证实了L1逆转录转座事件与基因组不稳定性及染色体外DNA（ecDNA）之间的直接联系。结果表明，L1插入是一种早期且克隆性的事件，能够引发染色体突变和病毒模仿免疫反应。此外，研究还发现APOBEC3B的表达与ecDNA的分布在空间维度上呈现相关性。这一系列成果不仅增进了对膀胱癌生物学特征的理解，还为开发新的诊断生物标志物和个性化治疗方案提供了科学依据。References:Pribus S J, Osredek I, Otoničar J, 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.
