Transport of mRNA from the nucleus to the cytoplasm is an essential process for gene expression in eukaryotic cells. In this unit, methods for monitoring nuclear mRNA export are described. Visualization of cellular mRNAs by fluorescence in situ hybridization with oligo(dT) probes is effectively applied to monitoring mRNA export from the nucleus in yeast and mammalian cells. In addition to the protocols for fluorescence in situ hybridization, this unit includes an alternate method that the authors have been developing for visual analysis of nuclear mRNA export in living mammalian cells by microinjection of fluorescently labeled pre-mRNA into the nuclei.
