ATP1B1 and acute myeloid leukemia: Expression of ATP1B1 was significantly higher in bone marrow (BM) from the primary cohort of 157 CN-AML patients than in normal BM (p < 0.001, Figure 1A, 116 CN-AML vs. 5 normal BM, GEO No: GSE1159), and similar results were obtained using other microarray data (Figure 1B, 9 CN-AML vs. 10 normal BM vs. 10 normal peripheral blood (PB); the 9 CN-AML consisted of 2 BM and 7 PB samples, GEO No: GSE9476).
