Overall, PARP1 was found to be highly expressed in CD34+ cells (paired CD34+ vs. CD34− subpopulations from 44 AML patients; GSE30029) (Figure 4F), as well as in CD34+CD38− cells, compared with CD34−CD38+ cells (CD34−CD38+ subpopulations from 54 AML patients vs. CD34−CD38+ cells from 69 AML patients; GSE76008) (Figure 4G). The gene discussed is CD34; the disease is acute myeloid leukemia.
