Non-coding RNAs (ncRNAs) are pivotal in gene regulation during development and disease. MicroRNAs have been extensively studied in neurogenesis. However, limited knowledge exists about the developmental signatures of other ncRNA species in sensory neuron differentiation, and human dorsal root ganglia (DRG) ncRNA expression remains undocumented. To address this gap, we generated a comprehensive atlas of small ncRNA species during iPSC-derived sensory neuron differentiation. Utilizing iPSC-derived sensory neurons and human DRG RNA sequencing, we unveiled signatures describing developmental processes. Our analysis identified ncRNAs associated with various sensory neuron stages. Striking similarities in ncRNA expression signatures between human DRG and iPSC-derived neurons support the latter as a model to bridge the translational gap between preclinical findings and human disorders. In summary, our research sheds light on the role of ncRNA species in human nociceptors, and NOCICEPTRA2.0 offers a comprehensive ncRNA database for sensory neurons that researchers can use to explore ncRNA regulators in nociceptors thoroughly.
非编码RNA(ncRNAs)在发育和疾病过程中的基因调控中起着关键作用。微小RNA已在神经发生中得到广泛研究。然而,关于其他ncRNA种类在感觉神经元分化过程中的发育特征,我们了解有限,并且人类背根神经节(DRG)的ncRNA表达情况尚无文献记载。为了填补这一空白,我们生成了一份诱导多能干细胞(iPSC)来源的感觉神经元分化过程中小ncRNA种类的综合图谱。利用iPSC来源的感觉神经元和人类DRG的RNA测序,我们揭示了描述发育过程的特征。我们的分析确定了与感觉神经元不同阶段相关的ncRNAs。人类DRG和iPSC来源的神经元之间ncRNA表达特征的显著相似性,支持将后者作为一个模型,以弥合临床前研究结果与人类疾病之间的转化差距。总之,我们的研究揭示了ncRNA种类在人类伤害感受器中的作用,并且NOCICEPTRA2.0为感觉神经元提供了一个全面的ncRNA数据库,研究人员可以利用它来深入探索伤害感受器中的ncRNA调节因子。
