Here is our article published in Nature Comm, on new players in chromatin dynamics after UV repair. This work highlights the histone chaperones DNAJC9 and MCM2 as central players in chromatin repair. Our proteomic dataset opens up new perspectives for dissecting epigenome maintenance mechanisms.

Glad to have been part of this great story and a fun collaboration between @saldivar-lab.bsky.social and @hamperllab.bsky.social! We discover an exciting new function of ATR in dissolving transcriptional condensates at the HLB to fine-tune linker histone expression and prevent genome instability.

PhDone! Last week, an incredible journey of 4.5 years came to an end when I defended my PhD at the LMU in Munich. I am tremendously grateful for all the fun moments throughout this chapter, full of learning and doing cool science.

Finally, also my family and friends who were always there for me and whose unvavering support made all of this possible in the first place! Moving forward, I am excited to continue my research as a PostDoc in Copenhagen!

Focusing on chromatin, we show that TRC induction stabilizes R-loops, which causes a drastic reduction of local nucleosome occupancy, suggesting that R-loops are incompatible with nucleosome formation. (4/n)

Intrigued by our findings on nucleosome dynamics, we screened several histone modifications for an association with TRCs. Strikingly, we discover H3K79me2/3 as a TRC-associated histone modification. (5/n)

To better answer this question, we first built a new reporter system based on genomic integration of the R-loop forming mAIRN sequence. We show that your system can efficiently induce TRCs, R-loops, and DNA damage. (2/n)

Transcription and replication are fundamental nuclear processes that require extensive chromatin remodeling to perform their function on the genome. What happens to chromatin if these two huge complexes collide in the genome? (1/n)
