770-Genes2Genes:单细胞轨迹的基因级贝叶斯动态对齐框架

from 聊聊Sci

本文介绍了一种名为 Genes2Genes (G2G) 的新计算框架,专门用于比较单细胞转录组数据中的伪时间轨迹。传统的动态时间规整(DTW)方法往往难以准确识别细胞状态之间的不匹配,而 G2G 结合了贝叶斯信息论与动态规划算法,能够精确捕捉基因水平上的序列匹配、扭曲以及插入或删除等失配现象。通过对模拟和真实数据集的验证,该工具在分析疾病细胞状态和优化体外培养条件方面展现了卓越的准确性。例如,它成功识别出体外培育的 T 细胞与体内发育状态在 TNF 信号通路上的表达差异。总之,G2G 为研究人员提供了一种强大的手段,通过基因聚类和差异动态表达分析,深入理解复杂的细胞发育过程。References: Sumanaweera D, Suo C, Cujba A M, et al.
