An immortalized multipotent otic progenitor (iMOP) cell was generated by transient expression of c-Myc in Sox2-expressing otic progenitor cells. The procedure activated endogenous c-Myc expression in the cells and amplified existing Sox2-dependent transcripts to promote self-renewal. Downregulation ...

Abstract: Chemogenomic fitness assays were combined with a transcriptome analysis to understand both the mode of action and the mechanisms of resistance to Chitosan oligosaccharides (COS). COS are deacetylated chitin compounds, with antimicrobial properties, that are presumed to act by disrupting t...

To assess the relative contributions of the PKA and MAPK pathways in Ras stimulation of filamentation, we examined the change in transcriptional profile following activation of Ras in strains in which one of these two pathways has been severed. These arrays contain the experiments involving WT strai...

DNA Immunoprecipitation was performed using purified, naked, genomic DNA and purified recombinant DNA binding domains for S. cerevisiae transcription factors (Cbf1, Leu3, Pho2, Pho4, Rap1, Rox1, and Swi5) and then competitively hybridized against input DNA on NimbleGen 385k whole-genome, 32bp, tilin...

The sequence specificity of DNA-binding proteins is the primary mechanism by which the cell recognizes genomic features. Here, we describe systematic determination of yeast transcription factor DNA-binding specificities. We obtained binding specificities for 112 DNA-binding proteins representing 19 ...
