Here, we determined the effect of four Artemis inhibitors 827171 (Figures 3A–C), 827032 (Figures 3D–F), 826941 (Figures 3G–I), 825226 (Figures 3J–L) and the DNA-PK inhibitor AZD7648 (Figures 3M–O) on the viability of patient-derived B-ALL cells (BLQ5, LAX56 and LAX7R) (Table 1) after an incubation time of 3 days. This evidence concerns the gene PRKDC and acute lymphoblastic leukemia.
