1363-结直肠癌中靶向TROP2揭示治疗驱动的细胞状态动力学
from 聊聊Sci
这份研究报告主要探讨了TROP2蛋白在结直肠癌（CRC）恶化、转移以及耐药性中的核心作用。研究发现，TROP2+细胞具有极强的细胞可塑性，能在低WNT信号状态下展现出癌症干细胞的特性，从而驱动肿瘤的远端转移。实验证明，常规化疗虽然能削减部分癌细胞，却会诱导肿瘤向高表达TROP2的胎儿样状态转变，导致治疗耐受。为了应对这一挑战，研究人员利用针对TROP2的抗体药物偶联物（ADC）精准打击这类细胞群，成功重塑了肿瘤的细胞构成。最终，通过将化疗与TROP2靶向疗法相结合，研究展示了在克服晚期肠癌耐药性及抑制转移方面的显著临床潜力。References:Vaquero-Siguero N, Georgakopoulos N, Puschhof M C, 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.
