The transcription factor FOXC1 (Fig. 2B), an important biomarker of basal-like breast cancer (Jensen et al. 2015), is a member of the anti-GATA3 group and is anticorrelated with GATA3 expression in TCGA data (Supplemental Fig. S2C; Pearson's r = −0.602). The gene discussed is FOXC1; the disease is breast carcinoma.
