摘要

秀丽隐杆线虫是研究神经元功能的强大模型,但尽管这种蠕虫中明确定义的神经元数量有限,但特定蛋白质和受体在单个神经元中的作用尚不清楚。St. Ange等人使用单核RNA测序(snRNA-seq)确定了野生型和daf-2蠕虫中每种神经元类型的转录组,已知daf-2蠕虫是胰岛素信号的突变体,具有改善记忆的作用。作者发现,神经元基因表达在L4幼虫和年轻成虫(第1天)阶段之间发生了显著变化;这导致了只有成年人才会出现的行为,比如丁酮联想学习。此外,作者还发现了先前与AWC相关的候选基因,这些基因在daf-2突变体的AWC化学感觉神经元中特异性上调,并且是AWC介导的学习和记忆所必需的。总之,这些数据提供了成年野生型和daf-2神经元基因表达图谱,具有功能行为见解,并强调snRNA-seq是识别仅在神经元子集中发生变化的基因的强大工具,因此在整个动物或特定组织的分析中可能被掩盖。原始参考文献:Cell Genom. 4,100720 (2024)

期刊介绍: Nature Genetics publishes the very highest quality research in genetics. It encompasses genetic and functional genomic studies on human and plant traits and on other model organisms. Current emphasis is on the genetic basis for common and complex diseases and on the functional mechanism, architecture and evolution of gene networks, studied by experimental perturbation. Integrative genetic topics comprise, but are not limited to: -Genes in the pathology of human disease -Molecular analysis of simple and complex genetic traits -Cancer genetics -Agricultural genomics -Developmental genetics -Regulatory variation in gene expression -Strategies and technologies for extracting function from genomic data -Pharmacological genomics -Genome evolution
