Therapeutic targeting of p300/CBP HAT domain for the treatment of NUT midline carcinoma.

ABSTRACT: Nuclear protein of the testis (NUT) midline carcinoma (NMC), is a rare and highly aggressive form of undifferentiated squamous cell carcinoma. NMC is molecularly characterized by chromosomal rearrangement of the NUT gene to another gene, most commonly the bromodomain and extraterminal domain (BET) gene BRD4, forming the BRD4-NUT fusion oncogene. Therefore, inhibiting BRD4-NUT oncogenic function directly by BET inhibitors represents an attractive therapeutic approach but toxicity may limit the use of pan-BET inhibitors treating this cancer. We thus performed a drug screening approach using a library consisting of epigenetic compounds and 'Donated Chemical Probes' collated by the Structural Genomics Consortium (SGC) and identified the p300/CBP HAT inhibitor A-485, in addition to the well-kno
