Screen for Chemoresistance in PPM1D Mutants
Various classes of chemotherapy agents were screened in the isogenic CRISPR-generated WT and PPM1D mutant cell lines (MOLM13, OCI-AML2, and OCI-AML3). The chemotherapy agents selected include key agents utilized in the treatment of primary tumors that t-AML/t-MDS patients in our cohort were previously exposed to. Dose response curves are shown, with red representing PPM1D mutants and gray representing WT. The data points represent mean ± SD of triplicates (n = 3).
