XPO1 and chronic myelogenous leukemia, BCR-ABL1 positive: In CML, selinexor inhibits the nuclear export protein XPO1 to block the NF-κB signaling pathway, downregulate GPX4 expression, and activate NCOA4-mediated ferritinophagy. In combination with ferroptosis inducers, it enhances lipid peroxidation, thereby overcoming drug resistance and inducing ferroptosis
