Global inhibition of deadenylation stabilizes the transcriptome in mitotic cells In the presence of cell division errors, mammalian cells can pause in mitosis for tens of hours with little to no transcription, while still requiring continued translation for viability. These unique...

New preprint! We solve a mystery you didn't know existed. Mitotic cells lack new transcription but require ongoing translation. Interphase mRNA half life is only 2-4 hrs. So how do cells arrest in mitosis for hours without depleting their transcriptomes?

Huge thanks to Nicky for guiding this work, and to the co-authors, this wouldn't be a paper without you πŸ₯° @nickywhiffin.bsky.social @elstondsouza.com @ruebenadawes.bsky.social @alextremophile.bsky.social and Alex Chan

The big takeaway?
UTRs are not silent. They’re critical regulatory regionsβ€”and can contain pathogenic variants just like protein coding exons do.

Why are UTR variants often missed?
πŸ‘‰ They’re rarely prioritised in clinical genomics
πŸ‘‰ Annotation tools are limited
πŸ‘‰ Functional consequences are hard to predict

The review outlines how UTR variants cause disease, such as:
- Create or remove upstream AUGs (uAUGs)
- Alter splicing
- Alter polyadenylation
- Interfere with miRNA or protein binding

UTRs regulate mRNA stability, translation, and localisation. A single UTR variant can derail protein production without touching protein coding sequence!

Most Mendelian disease diagnostics focus on coding regions - yet 5β€² and 3β€² UTRs contain important, overlooked variants.

incredibly interesting. do you know if there is more information on the genetic parents and whether their wishes were taken into account I.e. were they told they had to take the child or they were very much wanting to take it - and how much of a difference did their preferences make in this decision

As a recent graduate of a DPhil in Oxford could not recommend it more highly! Check these out and apply 😊
