Fig. 2. EGFR-dependency evaluation in a focused PRISM analysis of 20 NSCLC lines.
a Heatmap showed the response of 20 NSCLC lines to 5-day Erlotinib treatment (0, 0.1, 0.3, 1, 3, 10 µM) in individual CellTiter-Glo assay (top) or PRISM assay (bottom). b EGFR gene dependency of 20 NSCLC lines was evaluated by CRISPR competition assay (7 day, solid circles) and PRISM assay (5 day, solid squares). EGFR gene was knocked out by two single guide RNAs (sgEGFR1 and sgEGFR2), respectively. c Correlation analysis of Erlotinib AUC in individual CTG assay vs PRISM assay (20 cell lines, r = 0.9097). d Correlation analysis of Erlotinib AUC in PRISM assay vs AUC reported by Cancer Therapeutics Response Portal (CTRPv2, 18 cell lines, r = 0.7969). e Correlation analysis of EGFR CRISPR competition assay vs PRISM assay (plotted with average of two sgRNAs, 20 cell lines, r = 0.6844). f Correlation analysis of EGFR CRISPR PRISM assay vs DepMap gene effect score (CERES, 15 cell lines, r = 0.5098).
