The role of AP-1 in glucocorticoid resistance in leukaemia

Leukemia. 2001 Mar;15(3):391-7. doi: 10.1038/sj.leu.2402039.

Abstract

Glucocorticoids are used in the treatment of acute lymphoblastic leukaemia (ALL) and chronic lymphocytic leukaemia (CLL) but many patients develop glucocorticoid resistance on relapse. The ligand-activated glucocorticoid receptor inhibits activity of the AP-1 transcription factor and the purpose of this study was to test the hypothesis that up-regulation or overexpression of AP1-binding activity may be an important mechanism of glucocorticoid resistance in ALL and CLL. In vitro sensitivity of patient blasts to prednisolone was measured using th
