Many xenobiotics released in the aquatic environment exhibit a genotoxic potential toward organisms. Long term exposure to such compounds is expected to lead to multigenerational reproductive defects, further influencing the recruitment rate and hence, the population dynamics. Paternal exposure to

A serious limitation of the conventional comet assay (single cell gel electrophoresis) is the restriction on the number of samples that can be processed in one experiment, imposed by the size of the electrophoresis platform. One approach to increasing throughput

Observing cellular responses to perturbations is central to generating and testing hypotheses in biology. We developed a massively parallel microchemostat array capable of growing and observing 1,152 yeast-GFP strains on the single-cell level with 20 min time resolution. We measured

Poly(ADP-ribos)ylation (PARylation) is a reversible posttranslational modification found in higher eukaryotes. However, little is known about PARylation acceptor proteins. Here, we describe a sensitive proteomics approach based on high-accuracy quantitative mass spectrometry for the identification of PARylated proteins induced under

Bioactive compounds are widely used to modulate protein function and can serve as important leads for drug development. Identifying the in vivo targets of these compounds remains a challenge. Using yeast, we integrated three genome-wide gene-dosage assays to measure the
