We discovered that BRD4 expression was higher in tissues from patients with breast cancer (BRCA), colon adenocarcinoma (COAD), esophageal cancer (ESCA), head and neck squamous cell carcinoma (HNSC), kidney chromophobe (KICH), lung squamous cell carcinoma (LUAD), rectal adenocarcinoma (READ), stomach adenocarcinoma (STAD), sarcoma (SARC), and skin cutaneous melanoma (SKCM) than in tissues from healthy subjects (Fig. 1a). This evidence concerns the gene BRD4 and breast cancer.
