BRD3-NUT 10326 tumour sections after treatment with 2 mg/kg BI 894999, 5 mg/kg or 10 mg/kg CCS1477 and the combination of both. Upper row: IHC staining for proliferation marker Ki67. Middle row: Pseudocolour staining based on human mitrochondria stain. Red = tumour, green = stroma. Lower row: IHC staining for NUT protein. Strong reduction of tumour viable area and complete absence of proliferating tumour cells with combination treatment. Effect of BET monotherapy on tumour cells may be underestimated by in vivo tumour measurement.
