Inhibition of the Epigenetic Reader BRD4 Reduces SIRPα-Mediated Phagocytosis and Melanoma Invasion

Abstract

BRD4 acts as an epigenetic reader to regulate gene transcription. It represents a valid therapeutic target in cancer, and several selective and potent small molecule inhibitors have been discovered. A study by Le et al. (2020) published in Journal of Investigative Dermatology (2020) demonstrates that BRD4 inhibition reduces the invasive behavior of melanoma cells associated with matrix metalloproteinase-2 downregulation and increases phagocytosis by myeloid cells through SIRPα downregulation.
