Treatment with CEL for one week significantly reduced the levels of miR-155 as well as other CEL targets (Myb, Myc) in magnetically isolated c-Kit-positive myeloid progenitors compared to the control vehicle in treated AML-bearing 5–6-month-old PU.1ure/ure or control age-matched mice (Figure 1A). The gene discussed is KIT; the disease is acute myeloid leukemia.
