GATA1 and acute myeloid leukemia: GATA1 and GATA2 were more highly transcribed in AML as compared with B-ALL (p-value < 0.0001, Wilcoxon test) and T-ALL (p-value < 0.0001, Wilcoxon test), and GATA3 showed the highest level of transcription in T-ALL (p-values < 0.0001 in comparison with AML and B-ALL, Wilcoxon test).
