Ven was the inhibitor most associated with treatment resistance in RARA+ vs. RARA- samples. Additionally, MES (rho=0.58), RARA (rho=0.48) and BCL-2 expression (rho=-0.49) had similar magnitude of association with ex vivo Ven resistance, with RARA+ samples showing much lower ex vivo sensitivity to Ven than RARA- samples (p=3×10-8).
