1089-人类转录组中的必需lncRNA

这项研究利用CRISPR-Cas13技术对人类转录组进行了大规模筛选，旨在识别维持细胞生存所必需的长非编码RNA (lncRNAs)。研究人员在五种不同的细胞系中发现了788个关键lncRNAs，其中大部分表现出特定的细胞类型依赖性，只有极少数属于核心共享组。实验结果表明，这些必需的lncRNA大多独立于邻近的蛋白质编码基因发挥功能，而非仅仅通过调节周边基因来起作用。通过单细胞测序，研究进一步揭示了这些转录本在细胞周期调节和凋亡控制中的重要机制。此外，这些分子在人类胚胎发育早期高度表达，并与多种癌症的生存预后显著相关，为临床诊断和治疗提供了潜在的新生物标志物。References:* Liang W W, Mueller S J, Hart S K, et al.
