For ACVR2A, phosphorylation of the downstream activator SMAD2 was observed in all samples with predicted ACVR2A activity. (E) Summary of prediction accuracy and protein presence on the western blot level for all depicted top-hit proteins. (F) 10 of 12 samples were utilized for drug response assays with either the standard of care (SOC) reagents of each entity or the miRNA expression-based top targeted predicted drugs (PDs). In addition, randomly picked, targeted non-predicted drugs (NPDs) were included in selected drug screens. For each sample, fold changes between the pan-cancer Z score of SOC drugs and PDs are indicated. (G) Summary of all executed drug screens for all samples, depicted as individual pan-cancer Z scores for all included SOC, PD, and NPD therapies. (H) In vivo validation of drug screens. CRC02-SP and CRC03-SP cultures were transplanted subcutaneously into immunodeficient NSG mice. Total times from starting of the treatment until final tumor size are depicted as Kaplan-Meier curves. CRC02 xenografts were treated with the IGFR inhibitor linsitinib (n = 7). CRC03 xenografts were treated with the CDK4/6 inhibitor palbociclib (n = 6). ∗∗p < 0.01, Wilcoxon rank-sum test; ∗p < 0.05, log rank (Mantel-Cox) test.
