Today, we report that APOBEC3B targets unprotected single-stranded DNA at replication forks upon ATR inhibition, triggering a reaction cascade involving UNG2 and APE1 that leads to fork collapse and hyperactivation of PARP1, causing replication catastrophe. www.science.org/doi/10.1126/...

A beautiful News & Views by @unterholznerlab.bsky.social highlighting our latest paper in @natsmb.nature.com, where we show that transcription stress triggers an inflammatory response through the release of IL-1α. rdcu.be/ehkTV

Today, we report our new study demonstrating that PACT functions as an inhibitor rather than an activator of PKR, and works together with ADAR1 to suppress aberrant activation of PKR by self-derived double-stranded RNA. www.nature.com/articles/s41...

UCI Anteaters standing up for science today!

Very sad to read about the science funding situation in the US at the moment. I am waiting for some funding decisions in the coming weeks, but I will likely have opening(s) in my lab in Switzerland in the coming weeks (PhD student/postdoc). As a PhD candidate, you need to have a Master's degree.

Happy to report the 2025/05 NIH Biochemical and Cellular Oncogenesis (BCO) study section meeting has been rescheduled for late April. Just FYI.

The 2025/05 NIH Biochemical and Cellular Oncogenesis (BCO) study section meeting that was supposed to happen tomorrow has been rescheduled to a later date, to be determined. Just FYI for folks wondering. This is so disheartening.

Today @naturesmb.bsky.social 🥳, we report that the activation of NF-κB after DNA damage can occur through two distinct mechanisms. While ATM triggers NF-κB activation after DSBs, we found that IRAK1 specifically induces NF-κB in response to DNA damage causing transcriptional stress.

New Lab Preprint!🥳 Using CRISPR-Translate, a genome-wide CRISPR-Cas9 knockout screening method developed by the lab exploiting translation levels as a readout, we reveal that PACT is an inhibitor of PKR and not an activator during RNA viral infections. www.biorxiv.org/content/10.1...

New Lab Preprint! We show that ATR inhibition results in hyperactivation of PARP1 at replication forks, driven by APOBEC3B, UNG2, and APE1 reaction cascade targeting unprotected single-stranded DNA at the forks. www.biorxiv.org/content/10.1...

Great collaboration with Tim Fonton's team, which uncovered a new role for APOBEC3A during keratinocyte differentiation. @TimFenton10 showed that aberrant activation of GRHL3 in dividing cells could potentially drive mutagenic APOBEC3A activity in cancer. www.embopress.org/doi/full/10....

In our latest paper @pnas, we reported CRISPR-Translate, a genome-wide CRISPR-Cas9 knockout screen-based method designed to identify factors regulating translation. We discovered IRF2 as a novel regulator of OAS3/RNase L-mediated RNA decay during viral infections. www.pnas.org/doi/10.1073/...
