Using an iterative approach to eliminate ACB components with minor contribution to drug sensitivity correlation (AKR1C1, BLVRB, GSR and PTGR1), we observed a correlation of r = 0.69 (p = 0.002) between expression of the remaining 11 ACB genes and sensitivity of AML cells to DKFZ-682 (Supplementary Fig. S14B). The gene discussed is PTGR1; the disease is acute myeloid leukemia.
