1028-原位测序解析多维病理表型效应

from 聊聊Sci

本研究开发了一种名为 VIS-seq 的高通量单细胞成像分析平台,通过原位测序环状 RNA 条形码,将成千上万种蛋白质变异体与其产生的复杂细胞表型直接关联。研究人员利用该技术分析了 LMNA 和 PTEN 基因的数千种变异,揭示了变异如何影响蛋白质丰度、亚细胞定位以及细胞核形状等多个维度。实验结果证明,基因变异的效应呈现出连续的多维特征,而非简单的二元对立,这为理解疾病机理提供了更深入的视角。此外,VIS-seq 成功识别了与自闭症和肿瘤综合征相关的特异性变异效应,展示了其在精准医学中的巨大潜力。该平台还通过创新的基因表达盒设计,有效克服了干细胞及其衍生细胞中的基因沉默难题。总而言之,这项技术为在大规模尺度上探索分子到细胞的表型级联反应提供了强有力的工具。References:Pendyala S, Partington K, Bradley N, et al.
