BACH1 and cancer: POU3F2 (POU domain, class 3, transcription factor 2), BACH1 (breast cancer type 1 susceptibility protein; Igarashi et al., 2017), and STAT3 (signal transducer and activator of transcription 3; Kortylewski et al., 2005; Ho and Ivashkiv, 2006) were top 3 identified TFs from the shared up-regulated genes, leading to the activated immune response when down expressed in cells (Table 4, Figure 7A).
