Significantly higher expression in basal‐like tumors in relation to other cancer types (excluding normal‐like) was also observed in the case of ZNF789. As expected, high expression of these factors also correlated with negative staining for estrogen receptor (ER) and progesterone receptor (PR) in the TCGA dataset (Fig. 6B,C, Table 4). The gene discussed is ESR1; the disease is cancer.
