However, no significant difference was found in the mRNA level of other GATA members, including GATA1 (1.24 fold change, p=0.172), GATA2 (1.452 fold change, p=0.014), GATA4 (2.12 fold change, p=0.843), GATA5 (1.212 fold change, p=1.99e-4) and GATA6 (1.537 fold change, p=0.903), between breast cancer samples and normal controls (Figure 2A, 2B, 2E, 2F and 2G). This evidence concerns the gene GATA1 and breast cancer.
