The BRD4 inhibitor, JQ1, which blocks the ability of bromodomains to bind histones by competing for interaction with acetyl‐lysine motifs on histones, has been demonstrated to suppress lung cancer cell growth.[8] In addition to this, JQ1 has also been reported to restrain the proliferation of TAMs through CSF1/CSF1R signaling. The gene discussed is BRD4; the disease is lung cancer.
