Morpholino oligonucleotides (MOs)是一种有效的、基因特异性的反义敲低技术,应用于许多模型系统。本文描述了MOs在斑马鱼(Danio rerio)中用于基因活性的体内功能表征的应用。我们从基因靶选择开始总结我们的筛选经验。然后讨论筛选参数的考虑因素以及数据和数据库管理。最后,我们强调脱靶效应管理和彻底的下游表型验证的重要性。我们讨论了目前morpholino的局限性,包括在水溶液中储存时稳定性降低。MO技术的进步现在提供了一种对MO活动的时空控制措施,为将更精细的分析纳入基于MO的筛选提供了机会。因此,通过谨慎的管理,MOs仍然是发现筛选和个体基因敲低分析的宝贵工具。
Morpholino oligonucleotides (MOs) are an effective, gene-specific antisense knockdown technology used in many model systems. Here we describe the application of MOs in zebrafish (Danio rerio) for in vivo functional characterization of gene activity. We summarize our screening experience beginning with gene target selection. We then discuss screening parameter considerations and data and database management. Finally, we emphasize the importance of off-target effect management and thorough downstream phenotypic validation. We discuss current morpholino limitations, including reduced stability when stored in aqueous solution. Advances in MO technology now provide a measure of spatiotemporal control over MO activity, presenting the opportunity for incorporating more finely tuned analyses into MO-based screening. Therefore, with careful management, MOs remain a valuable tool for discovery screening as well as individual gene knockdown analysis.
