Abstract
Abstract High throughput screening (HTS) is used to screen large numbers of small molecules in cell-based assays to predicting their potential therapeutic response and when applying approved drug libraries using HTS it becomes drug repurposing. The Drug Sensitivity and Resistance Testing (DSRT) platform established at FIMM has been extensively used in testing panels of approved and investigational drugs on cells, both conventional cell lines and primary cell models derived from cancer patient samples. The results help in deepen our understanding of drug efficacy in individual patients and across specific disease to guide future patient stratification. Breeze 2.0 is an open access, web-based platform for interactive analysis of drug screening data in real time. Breeze accepts raw data in a simple tabular format and generates detailed quality control metrics, plots, dose-response curve fits, drug response quantification in form of IC50/EC50/AUC and Drug Sensitivity Scores (DSS). Besides tabular results, Breeze generates interactive, informative, and intuitive visualizations, such as plate heatmaps, scatterplots, barplots, clustered heatmaps, circular plots, for further analysis. Based on manually-curated published datasets available through Breeze 2.0, users can instantly compare their drug response patterns with the existing DSRT profiles from patient samples, as well as cell lines. Importantly, Breeze 2.0 has integrated curated reference DSRT data tested on bone marrow samples from healthy control individuals, which plays a crucial role in understanding cancer-selective drug response by de-prioritizing generally toxic compounds. The end-users can select multiple healthy controls or relevant patient/cell line samples and choose the drugs of interest to visualize the overlaid dose responses, as well as response quantification metrics.
