Key takeaways:
πŸ” Oxidative damage causes an instant shutdown of transcription, but unlike UV, without RNAPII degradation
πŸ” Stalled RNAPII resumes transcription from within the gene body
πŸ” PARylation controls early elongation restart
πŸ” BER and SSBR repair enable RNAPII recovery in the gene body

This beautiful work, led by Quentin Thomas, revealed a surprising spatial organization of the transcriptional response:

πŸ”¬ Promoter regions: PARylation governs early RNAPII release
πŸ”¬ Gene body: DNA damage and repair drive RNAPII stalling

Oxidative stress triggers RNAPII arrest through PARylation and DNA damage UV or gamma irradiation, as well as certain chemicals, generate DNA damage that disrupts transcription through a variety of well-characterised mechanisms. In contrast, the transcriptional response to ...

What happens to transcription upon oxidative DNA damage? 🧬πŸ’₯

RNAPII halts instantly within genes ⛔️ and even more surprisingly: It restarts from where it stopped without leaving the DNA template 🚦

πŸ‘€πŸ“„ How does this happen? Find out in our new preprintπŸ‘‡ www.biorxiv.org/cgi/content/...

What did we find? βœ… Elongation rates vary between genes βœ… …and within genes βœ… Histone marks & elongation factors correlate with rate subclasses

Existing methods either rely on indirect estimates or are limited to a handful of long genes. So we built DRB/TTchem-seq2: Short timepoint sampling, new computational framework πŸ“ˆ leading to a ~7 fold increased individual gene elongation rates measurements!

Such a beautiful example of how tight control of transcriptional activity is achieved and even more important: plays a crucial developmental role. Congratulations @jzylicz.bsky.social and team!
