Figure 5Mean IC50 (µM) values of APR-246 in 17 different cell lines (n ≥ 3) as shown by WST-1. *p = 0.03, Mann Whitney test. Mean IC50 (µM) values for APR-246 treatment and n for individual cell lines are also shown in Fig 1C and listed in Table S1. Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5. Box-and-whisker plot of Pearson correlations between PRIMA-1 area-under-the-curve (AUC) and the levels of 225 different metabolites from the DepMap portal. Central band indicates median, boxes indicate 25th and 75th percentile, and whiskers show 2.5th and 97.5th percentile outlier metabolites. High GSH and GSSG (in red) correlate with low PRIMA-1 sensitivity. Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5. Total intracellular glutathione (GSH+GSSG) as shown by glutathione reductase (GR) re-cycling assay in H1299 R175H (tet-off) (+/- doxycycline) and H1299 -/- cells 24h after seeding (n = 3). Indicated values are fold change compared to mutant TP53 cells. Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5. Total intracellular glutathione (GSH+GSSG) as shown by GR re-cycling assay in untreated HCT116 (R248W, WT and -/-) cells 48h after seeding (n = 3, 5 or 2 respectively). Indicated values are fold change to mutant TP53 cells. Part of this data is shown in Fig. EV4. Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5. Thiol tracker staining by flow cytometry 48h after seeding of the indicated untreated cells (n = 2) Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5. Correlation between 14C accumulation (cpm/mg x ml-1) after treatment with 25 µM 14C-APR-246 and IC50 (µM) values for APR-246 in 11 cell lines (n ≥ 3) (r = -0.66, p = 0.03, Pearson correlation). Each dot represents one cell line, 14C accumulation data are shown in Fig 3B and values and n for individual cell lines are listed in Table S1 and S3. Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5. ABCC1 mRNA Expression, RSEM (Batch normalized from Illumina HiSeq_RNASeqV2) in lung cancer (luad & lusc studies, *p<0.0001) and colon adenocarcinoma (coad study, *p=0.005) grouped into having no alterations or putative driver missense mutations in TP53. Statistical analysis by Mann Whitney test, n is indicated in the figure. Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5. 14C accumulation (cpm/mg x ml-1) in H1299 R175H cells (+/- doxycycline) and H1299 -/- cells after 24h treatment with 14C-APR-246 (n = 2). Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5. Growth suppression in H1299 R175H cells (+/- doxycycline) and H1299 -/- cells treated for 72h with APR-246 as shown by WST-1 assay (n = 3). Data information: TP53 status is indicated for each cell line. Data are represented as mean ± SEM. See also Figure EV5 and Appendix Figure S5.
