1 Leukemic cellular retinoic acid resistance and missense mutations in the PML-RARalpha fusion gene after relapse of acute promyelocytic leukemia from treatment with all-trans retinoic acid and intensive chemotherapy. Tretinoin PML nuclear body scaffold Homo sapiens
2 This study evaluated whether relapse of acute promyelocytic leukemia (APL) patients from clinical remissions achieved and/or maintained with all-trans retinoic acid (RA) in combination with intensive chemotherapy is associated with leukemic cellular resistance to RA and with alterations in the PML-RARalpha fusion gene. Tretinoin PML nuclear body scaffold Homo sapiens
3 We conclude that APL cellular resistance occurs with high incidence after relapse from RA + DA therapy administered in a nonconcurrent manner and that mutations in the RARalpha region of the PML-RARalpha gene are present in and likely mechanistically involved in RA resistance in a subset of these cases. Tretinoin PML nuclear body scaffold Homo sapiens
