BRD4 and cancer: JQ1, a potent inhibitor of Bromodomain-Containing Protein 4 (BRD4), has also been shown to preferentially localize within MED1 condensates, alongside other critical molecules involved in transcription regulation.590 The increased concentration of JQ1 within these condensates can disrupt transcriptional activities by selectively affecting the expression of oncogenes associated with SE regions where MED1 condensates reside.592,593 Thus, JQ1 demonstrates the potential for targeting cancer cells that depend on MED1 condensates.
