The mechanistic and therapeutic differences in the cellular response to DNA-damaging compounds are not completely understood, despite intense study. To expand our knowledge of DNA damage, we assayed the effects of 12 closely related DNA-damaging agents on the complete pool of approximately 4,700 barcoded homozygous deletion strains of Saccharomyces(More)
Next-generation sequencing has proven an extremely effective technology for molecular counting applications where the number of sequence reads provides a digital readout for RNA-seq, ChIP-seq, Tn-seq and other applications. The extremely large number of sequence reads that can be obtained per run permits the analysis of increasingly complex samples. For(More)
The present experiment studied horizontality representation among men and women performing the water-level task either in visual conditions (the subjects saw outlines of tilted containers in which they respectively drew or set the water line) or in partially and totally haptic conditions (respectively, the subjects both saw and felt or merely felt the(More)
Genome-scale CRISPR interference (CRISPRi) has been used in human cell lines; however, the features of effective guide RNAs (gRNAs) in different organisms have not been well characterized. Here, we define rules that determine gRNA effectiveness for transcriptional repression in Saccharomyces cerevisiae. We create an inducible single plasmid CRISPRi system(More)
Mitochondrial diseases are systemic, prevalent and often fatal; yet treatments remain scarce. Identifying molecular intervention points that can be therapeutically targeted remains a major challenge, which we confronted via a screening assay we developed. Using yeast models of mitochondrial ATP synthase disorders, we screened a drug repurposing library, and(More)
Cas9, a CRISPR-associated RNA-guided nuclease, has been rapidly adopted as a tool for biochemical and genetic manipulation of DNA. Although complexes between Cas9 and guide RNAs (gRNAs) offer remarkable specificity and versatility for genome manipulation, mis-targeted events occur. To extend the understanding of gRNA::target homology requirements, we(More)
