Sign transducer and activator of transcription (STAT)5 is constitutively activated in BCR/ ABL-expressing cells but the mechanisms and functional consequences of such activation are unknown. transfected with STAT5 activation-deficient BCR/ABL SH3+SH2 mutants restored protection from apoptosis stimulated growth factor-independent cell cycle progression and rescued the leukemogenic potential in mice. Moreover expression of a dominant-negative STAT5B… Continue reading Sign transducer and activator of transcription (STAT)5 is constitutively activated in
