Expression of

IL-3 in the aCML case with a t(5;12)(q31;p13) (case 7). Expression of IL-3 but not of CSF2, IL-5, or IL-9 was detected in a bone marrow sample from the patient with aCML (case 7). By contrast, high-level expression of IL-3 could not be detected in control bone marrow cells (BM), indicating ectopic expression of IL-3 in the t(5;12) case. The faint band observed at 394 bp in control bone marrow is due to a genomic contamination of the RNA sample.
