Supplemental Figures 1-9 from Combined Targeting of the BRD4–NUT–p300 Axis in NUT Midline Carcinoma by Dual Selective Bromodomain Inhibitor, NEO2734

Supplemental Figure S1: NEO2734 induces differentiation in 10-15 cells. Supplemental Figure S2: Caspase-mediated apoptosis plays a minimal role in the activity of GNE-781, OTX015, or NEO2734. Supplemental Figure S3: BRD4-NUT protein levels decrease slightly upon exposure to NEO2734. Supplemental Figure S4: Global H3K27Ac levels do not change upon exposure to NEO2734. Supplemental Fig. S5. BRD4-NUT foci diminish over time course in TC-797 cells. Images were taken at identical magnification (1000x) with identical exposure settings per stain. Supplemental Figure S6. Dot plots of fold change of gene expression in samples treated with the indicated compound versus that in DMSO-treated samples. Supplemental Figure S7: Proportion of differentially expressed genes overlapping BRD4-NUT megadomains is greater in genes whose expression is downregulated in the presence of p300/CBP and/or BET bromodomain inhibition. Supplemental Figure S8: Tolerability in the full 10-15 mouse xenograft study. Supplemental Figure S9: Cleaved PARP is unchanged, but BRD4-NUT is somewhat depleted in mouse xenograft tumors exposed to NEO2734.
