    Bromodomain inhibition of the transcriptional coactivators CBP/EP300 as a therapeutic strategy to target the IRF4 network in multiple myeloma

    Andrew R Conery, Richard C Centore ... Robert J Sims III
    CBP/EP300 bromodomain inhibitors have a therapeutic application in oncology via targeting the IRF4 transcriptional program, a clinically validated network critical for multiple myeloma cell viability.

    Mapping cell type-specific transcriptional enhancers using high affinity, lineage-specific Ep300 bioChIP-seq

    Pingzhu Zhou, Fei Gu ... William T Pu
    A method for measuring p300 chromatin occupancy in specific lineages of mouse tissues was used to map endothelial enhancers and to identify previously unrecognized angiogenesis-related sequence motifs.

    Short-chain fatty acids activate acetyltransferase p300

    Sydney P Thomas, John M Denu
    At most physiological concentrations, the short-chain fatty acids propionate and butyrate affect histone acetylation by modifying and activating the acetyltransferase p300/CBP, rather than by inhibiting histone deacetylases.

    Hdac6 regulates Tip60-p400 function in stem cells

    Poshen B Chen, Jui-Hung Hung ... Thomas G Fazzio
    A normally cytoplasmic deacetylase, Hdac6, localizes to the nucleus in embryonic stem cells, where it regulates the essential Tip60-p400 chromatin remodeling complex.

    Event-related modulation of alpha rhythm explains the auditory P300-evoked response in EEG

    Alina Studenova, Carina Forster ... Vadim Nikulin
    The decrease in alpha rhythm amplitude in the parietal regions after the presentation of a deviant auditory stimulus gives rise to a part of the P300-evoked response.

    Transcranial focused ultrasound to human rIFG improves response inhibition through modulation of the P300 onset latency

    Justin M Fine, Archana S Mysore ... Marco Santello
    Ultrasonic neurostimulation in humans can manipulate response inhibition related behavior and neural activity.

    Promoter-specific changes in initiation, elongation, and homeostasis of histone H3 acetylation during CBP/p300 inhibition

    Emily Hsu, Nathan R Zemke, Arnold J Berk
    CBP/p300 acetylation of histone H3 at promoters and enhancers stimulates transcriptional elongation through recruitment of the super-elongation complex and BRD4.

    Convergent organization of aberrant MYB complex controls oncogenic gene expression in acute myeloid leukemia

    Sumiko Takao, Lauren Forbes ... Alex Kentsis
    Definition of leukemia gene expression mechanisms reveals general principles of cancer gene control and offers a pharmacologic strategy for its therapeutic reprogramming.

    Salicylate, diflunisal and their metabolites inhibit CBP/p300 and exhibit anticancer activity

    Kotaro Shirakawa, Lan Wang ... Eric Verdin
    Salicylic acid, the precursor to aspirin, is an anti-tumor agent that blocks protein acetylation.

    p50-associated COX-2 extragenic RNA (PACER) activates COX-2 gene expression by occluding repressive NF-κB complexes

    Michal Krawczyk, Beverly M Emerson
    A long non-coding RNA removes the transcriptional repressor p50 to regulate recruitment of co-activator p300 and RNA Polymerase II complexes to activate the COX-2 gene in human mammary epithelial cells and macrophages.
