What a week, within just a few days our lab member Federico Teloni got his work accepted for publication in Molecular Cell and also successfully defended his PhD thesis. Huge congratulations to him and to the whole lab for these fantastic achievements!
Our newest paper on PARP inhibitor toxicity is published in Nature Communications! Check how high-content imaging reveals the earliest cellular responses to PARP inhibition and unravels the sequence of events from PARP trapping to DNA damage, cell cycle arrest and cell death.
We are always looking for motivated postdoctoral researchers and/or MSc/PhD students to join our lab. If you are interested in chromatin dynamics and genome stability and have a liking for quantitative cell biology, please take a look at our open positions.

Exploiting the full potential of anti-cancer drugs necessitates a detailed understanding of their cytotoxic effects. While standard omics approaches are limited to cell population averages, emerging single cell techniques currently lack throughput and are not applicable for compound screens. Here, we employed a versatile and sensitive high-content microscopy-based approach to overcome these limitations and quantify multiple parameters of cytotoxicity at the single cell level and in a cell cycle resolved manner. Applied to PARP inhibitors (PARPi) this approach revealed an S-phase-specific DNA damage response after only 15 min, quantitatively differentiated responses to several clinically important PARPi, allowed for cell cycle resolved analyses of PARP trapping, and predicted conditions of PARPi hypersensitivity and resistance. The approach illuminates cellular mechanisms of drug synergism and, through a targeted multivariate screen, could identify a functional interaction between PARPi olaparib and NEDD8/SCF inhibition, which we show is dependent on PARP1 and linked to PARP1 trapping.
Our research and experimental approach was recently featured in a High Content Imaging (HCI) Special in BIOspektrum, the magazine of the German bioscience societies GBM, VAAM, GfG and DGPT. Have a look at the current issue, HCI is not only about large-scale screens. Here is the article and here the link to the complete issue.
