As a transcriptional coactivator, BRD4 has been implicated in the aberrant expression of several oncogenes in breast cancer cells, including c-MYC, p53, FOXM1, and NF-κB (Pérez-Salvia et al., 2017; Pérez-Peña et al., 2018; Yang et al., 2021; Zhou et al., 2022). This evidence concerns the gene BRD4 and breast carcinoma.
