The transcripts of the IK target genes were not down-regulated in primary leukemia specimens of 122 BCR-ABL+ pediatric BPL patients vs. normal hematopoietic cells in 74 healthy bone marrow specimens reported in the “Microarray Innovations in Leukemia” (MILE) study (Figure S4 in File S1). The gene discussed is IK; the disease is leukemia.
