RNF38 promotes gilteritinib resistance in acute myeloid leukemia via inducing autophagy by regulating ubiquitination of LMX1A.

Background: Gilteritinib is a commonly used targeted drug for acute myeloid leukemia (AML), but the emergence of gilteritinib resistance greatly reduces the therapeutic effect. RING finger protein 38 (RNF38), a protein with RING Finger domain and E3 ubiquitin ligase activity, has been implicated in tumorigenesis and drug resistance. However, the role and mechanism of RNF38 in the gilteritinib resistance of AML remains unclear.
