1459-LCP2调控SUV39H1轴介导NK/T细胞淋巴瘤耐药研究
from 聊聊Sci
这项研究揭示了LCP2蛋白在自然杀伤/T细胞淋巴瘤（NKTCL）化疗耐药中的核心调控作用。研究发现，化疗诱导的细胞衰老会导致LCP2表达下调，进而激活IQGAP2/LaminA/C/SUV39H1信号轴，促使肿瘤细胞产生耐药性并形成免疫抑制微环境。实验数据表明，LCP2的缺失与患者病情复发及较差的预后密切相关。通过联合使用衰老抑制剂Epitalon和SUV39H1抑制剂Chaetocin，可以有效清除衰老细胞并逆转耐药。该发现不仅确定了LCP2作为衰老相关耐药的关键生物标志物，还为治疗难治性淋巴瘤提供了全新的衰老靶向治疗方案。References:Zhang Y, Qian S, Yang Q, 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.
