High-Throughput Transcriptomics Platform for Screening Environmental Chemicals

We screened 44 chemicals in MCF7 cells in concentration response and generated HTTr data using the TempO-Seq hWTv1 assay. First, we provide an outline of the quality of the HTTr data based on a set of QC metrics we developed for this platform. Second, we evaluate the reproducibility and mechanistic accuracy of the HTTr platform using inter-plate analysis of reference samples and comparison of reference chemical treatment effects with CMAP signatures, respectively. Third, we summarize the concentration-dependent HTTr responses for all 44 chemicals to stratify them in terms of their overall effect on the transcriptome. Fourth, we present a new gene signature based concentration-response analysis that provides potency estimates for perturbation of cellular biology (ie, BPACs). This dataset is associated with the following publication: Harrill, J., L. Everett, D. Haggard, T. Sheffield, J. Bundy, C. Willis, R. Thomas, I. Shah, and R. Judson. High-Throughput Transcriptomics Platform for Screening Environmental Chemicals. TOXICOLOGICAL SCIENCES. Society of Toxicology, RESTON, VA, 181(1): 68-89, (2021).
