a, Expression levels of RBFOX2 in patients with primary AML bearing chromosomal translocations and those in bone marrow (BM) HSCs collected from healthy donors (healthy BM) (GSE13159 (ref. 49)). n = 73 for healthy BM, n = 38 for MLL, n = 38 for t(15;17) and n = 351 for normal karyotype. Two-sided P values were calculated by Student’s t-test. b, Kaplan–Meier survival analysis in GSE1159 (ref. 50) and GSE14468 (ref. 51) dataset (n = 485). The patients were divided into two groups of equal size based on RBFOX2 levels. c, In vitro LDAs. Logarithmic plot showing the percentage of non-responding wells at different doses. Non-responding wells are wells not containing colony-forming cells. The estimated LSC/LIC frequency is calculated by ELDA and shown on the right. d, Bioluminescence imaging of mice transplanted with luciferase-expressing MOLM13 cells transfected with control (shNS) and RBFOX2 shRNAs (shRBFOX2-1 and shRBFOX2-2), respectively. D, day. e, Kaplan–Meier survival curves of recipient mice transplanted with control (n = 9) and two RBFOX2 KD (n = 10 for shRBFOX2-1 and n = 9 for shRBFOX2-2) MOLM13 cells. f, Flow cytometric analysis (top) and quantification (bottom) of CD11b+ cell populations in control and RBFOX2 KD AML-PDX cells (2017-129 (ref. 44)). n = 2. g, Bioluminescence imaging of mice transplanted with luciferase-expressing AML-PDX cells (2017-129 (ref. 44)) transduced with shNS and RBFOX2 shRNAs (shRBFOX2-1 and shRBFOX2-2), respectively. h, Kaplan–Meier survival curves of recipient mice transplanted with control (n = 8) and RBFOX2 KD (n = 7 for shRBFOX2-1 and n = 8 for shRBFOX2-2) AML-PDX cells (2017-129 (ref. 44)). n, biologically independent samples. Data are presented as mean ± standard error of the mean. For b, c, e and h, P values were calculated by the log-rank test.
