Great talk yesterday by @hilgerslab.bsky.social on RNA complexity in the nervous system @cgen2025.bsky.social @ucph.bsky.social mRNA isoform regulation occurs at multiple levels, with crosstalk between start and end of mRNA transcripts and serves a critical role to safeguard neuronal gene expression

SCAF1 driven polyadenylation site usage regulates mRNA isoform expression and neuronal differentiation Accurate co-transcriptional processing is required for correct gene expression of mRNA transcript isoforms under unperturbed conditions, but particularly during development, to ensure tissue-specific ...

What is the function of the RNAPII-interacting SCAF proteins?

In our latest work, led by Smaragda Kompocholi, we show that SCAF1 shapes mRNA isoform expression during neuronal differentiation 🧬 🧠

Loss of SCAF1 → shorter transcripts

Key takeaways:
🔍 Oxidative damage causes an instant shutdown of transcription, but unlike UV, without RNAPII degradation
🔍 Stalled RNAPII resumes transcription from within the gene body
🔍 PARylation controls early elongation restart
🔍 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:

🔬 Promoter regions: PARylation governs early RNAPII release
🔬 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? 🧬💥

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

👀📄 How does this happen? Find out in our new preprint👇 www.biorxiv.org/cgi/content/...

What did we find? ✅ Elongation rates vary between genes ✅ …and within genes ✅ 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 📈 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!
