Luciferase reporter assays and immunoblot analyses demonstrated that PSMD1 and PSMD3 promote NF-κB protein expression in CML, and that signal transducer and activator of transcription 3 (STAT3) further activates NF-κB in scenarios of TKI resistance. This evidence concerns the gene PSMD3 and chronic myelogenous leukemia, BCR-ABL1 positive.
