991-人类细胞遗传相互作用图谱

这项研究通过对人类 HAP1 细胞系中约 400 万个基因对进行大规模 CRISPR 扰动分析，成功构建了一个包含约 8.9 万个相互作用的全基因组遗传相互作用图谱。该图谱揭示了人类细胞的功能架构，发现其网络拓扑结构在进化上高度保守，表现出与酵母相似的层次化模块特征。研究人员通过该网络识别出了许多此前未被表征的基因功能，并深入探讨了重复基因（旁系同源基因）在遗传补偿中的关键作用。此外，通过整合 DepMap 癌症依赖性数据，该成果能够精确解析特定癌症细胞系的遗传依赖机制，为寻找合成致死等潜在治疗靶点提供了重要参考。这种数据驱动的策略不仅深化了对人类基因组功能的理解，也为推进精准医疗和药物研发奠定了坚实基础。References:* Billmann M, Costanzo M, Zhang X, et al.
