    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.

    The Brm-HDAC3-Erm repressor complex suppresses dedifferentiation in Drosophila type II neuroblast lineages

    Chwee Tat Koe, Song Li ... Hongyan Wang
    A novel complex composed of various components of a chromatin remodeling complex, a chromatin remodeling factor and a transcription factor suppresses the dedifferentiation of intermediate neural progenitors back into neuroblasts in Drosophila.

    Acetylation of histone H3 at lysine 64 regulates nucleosome dynamics and facilitates transcription

    Vincenzo Di Cerbo, Fabio Mohn ... Robert Schneider
    The acetylation of histones at specific sites close to DNA can regulate transcription.

    Resveratrol modulates the inflammatory response via an estrogen receptor-signal integration network

    Jerome C Nwachukwu, Sathish Srinivasan ... Kendall W Nettles
    Anti-inflammatory effects of resveratrol are mediated by the estrogen receptor to coordinate a complex array of transcriptional coregulators, suggesting that estrogenic effects must be considered in the complex polypharmacology of resveratrol.

    Coordinated control of senescence by lncRNA and a novel T-box3 co-repressor complex

    Pavan Kumar P, Uchenna Emechebe ... Anne M Moon
    A novel master regulatory mechanism of cell proliferation and senscence employs the lncRNA UCA1 and a CAPERα/TBX3 corepressor.

    Polycomb- and REST-associated histone deacetylases are independent pathways toward a mature neuronal phenotype

    James C McGann, Jon A Oyer ... Gail Mandel
    Poised neuronal genes are repressed by REST and Polycomb in embryonic stem cells independently and via different chromatin modifications.

    Heterochromatin assembly and transcriptome repression by Set1 in coordination with a class II histone deacetylase

    David R Lorenz, Lauren F Meyer ... Hugh P Cam
    Set1 has roles in chromatin organization and transcriptome control that are largely independent of histone H3 lysine 4 methylation.

    Defective apical extrusion signaling contributes to aggressive tumor hallmarks

    Yapeng Gu, Jill Shea ... Jody Rosenblatt
    Disrupting extrusion, a process that drives epithelial cell death, leads to increased cell survival, poor barrier function, and enhanced cell invasion and, thereby, promotes tumor initiation and progression.

    Autoinhibition of Bruton's tyrosine kinase (Btk) and activation by soluble inositol hexakisphosphate

    Qi Wang, Erik M Vogan ... John Kuriyan
    A key B-cell tyrosine kinase that adopts an autoinhibited conformation, and can be activated by either membrane recruitment or soluble inositol hexakisphosphates in solution.

    Transcription factor MITF and remodeller BRG1 define chromatin organisation at regulatory elements in melanoma cells

    Patrick Laurette, Thomas Strub ... Irwin Davidson
    The PBAF chromatin-remodelling complex is essential for the proliferation of melanocytes and melanoma cells and is recruited to critical regulatory elements by physical and functional interactions with MITF, a transcription factor and master regulator of melanoma.
