FLT3 and leukemia: It is first shown by our study that upregulation of IL2RA was correlated with upregulation of FLT3 tyrosine kinase transcripts [53] and of transcription factor ID1, a key common target of oncogenic tyrosine kinases that contribute to transformation of leukemias [56], indicating a strong association of IL2RA expression with tyrosine kinases pathways.
