(A) Schematic of the shRNA library screen for ALK TKI sensitizers (left), with a representative Venn diagram of shRNAs that sensitized cells to crizotinib, alectinib or both (middle), and representative viability assays for one of these targets, CC2D1A (right). Data represents results from a single experiment, where five unique shRNA were targeted to each gene, and each drug/shRNA effect was assayed in five replicates (B and C) Interactions among the proteins that sensitized cells to crizotinib (B) and alectinib (C) were extracted from the entire EML4-ALK interaction network. The protein types and pTyr change induced by crizotinib are highlighted.
