Visualization of Nuclear and Cytoplasmic Long Noncoding RNAs at Single-Cell Level by RNA-FISH

Methods Mol Biol. 2021:2157:251-280. doi: 10.1007/978-1-0716-0664-3_15.

Abstract

The RNA fluorescence in situ hybridization (RNA-FISH) methodology offers an attractive strategy to deepen our knowledge on the long noncoding RNA biology. In this chapter, we provide a comprehensive overview of the current RNA-FISH protocols available for imaging nuclear and cytoplasmic lncRNAs within cells or tissues. We describe a multicolor approach optimized for the simultaneous visualization of these transcripts with their specific molecular interactors, such as proteins or DNA sequences. Common challenges faced by this methodology such as cell-type specific permeabilization, target accessibility, image acquisition, and post-acquisition analyses are also discussed.

Keywords: Immunofluorescence; In situ hybridization; RNA-FISH; Single-cell detection; lncRNA; ncRNA.
