mRNA export factors store nascent transcripts within nuclear speckles as an adaptive response to transient global inhibition of transcription Transcription inhibitors also disrupt nuclear export. Here, Williams et al. reveal that mRNA export factors sense transcription inhibition and adapt by storing mature export-competent mRNA in nuclear speckles. This enables rapid release when transcription resumes and ensures retention of cellular identity and viability during a transient global transcription insult.

ÅNGSTRÖM-RESOLUTION FLUORESCENCE MICROSCOPY.

Can we do structural biology with an optical microscope? Yes!

Check out how we resolved *single bases of DNA* and much more using fluorescence microscopy, out on 24.05.2023 in Nature! @natureportfolio.bsky.social

We’ve just installed a new Abberior STED FACILITY LINE microscope at Nicolaus Copernicus University. Next week, we begin studying Cajal bodies, P-bodies, SG and other biomolecular condensates in post-transcriptional gene regulation. Thanks @ministerstwonauki.bsky.social for their financial support.
