‘’July 2021: Check out our work on the exquisite dependence of PTEN mutant Non-Small Cell Lung Cancer for ATM to evade radiotherapy, available as preprint via BioRxiv: https://www.biorxiv.org/content/10.1101/2021.07.24.453632v1
“June 2021: Coming soon! We are recruiting a PhD student in tumourigenesis with a background in biochemistry or biomedicine.”
“May 2021: Our graduate college “Understanding Ubiquitylation: From Molecular Mechanisms to Diseases” was granted a second funding period by the DFG for another 4,5 years starting in October 2021!”
“Feb 2021: Dr. Camina Fuss started as a new member of our lab. As a clinican scientist, her research work will focus on modelling adrenocortical cancer and identification of so far unexplored dependencies and vulnerabilities for therapy.
