    A lncRNA fine tunes the dynamics of a cell state transition involving Lin28, let-7 and de novo DNA methylation

    Meng Amy Li et al.
    A novel lncRNA (Ephemeron) is connected to known post-transcriptional and epigenetic regulators as part of an integrated machinery, which controls the timely exit from the naïve state of mouse embryonic stem cells.

    In vivo targeting of de novo DNA methylation by histone modifications in yeast and mouse

    Marco Morselli et al.
    DNA methylation deposition is dependent on the presence of H3K4me3 and H3K36me3 histone marks.

    Epimutations are associated with CHROMOMETHYLASE 3-induced de novo DNA methylation

    Jered M Wendte et al.
    Simultaneous targeting of loci by pathways that promote euchromatin and heterochromatin primes transcribed genes for epimutations in the form of CG DNA methylation.

    Identification of Pol IV and RDR2-dependent precursors of 24 nt siRNAs guiding de novo DNA methylation in Arabidopsis

    Todd Blevins et al.
    The 24-nucleotide long siRNAs that guide cytosine methylation in Arabidopsis are made by dicing short double-stranded RNAs that are only around 30 nucleotides long.

    Epigenetic regulation of hematopoiesis by DNA methylation

    Aniket V Gore et al.
    Methylation of a key transcription factor gene by a de novo DNA methyltransferase assures the maintenance of hematopoietic stem cell fate.

    The ‘de novo’ DNA methyltransferase Dnmt3b compensates the Dnmt1-deficient intestinal epithelium

    Ellen N Elliott et al.
    The maintenance methyltransferase Dnmt1 and the de novo methyltransferase Dnmt3b cooperate to maintain DNA methylation and genomic stability in the adult intestinal epithelium.

    Computational prediction of CTCF/cohesin-based intra-TAD loops that insulate chromatin contacts and gene expression in mouse liver

    Bryan J Matthews, David J Waxman
    Certain types of 3D chromatin loops are easy to predict from existing or easily obtainable 2D information, which benefits gene expression studies in tissues/cells/organisms without extensive pre-existing 3D information.

    Molecular architecture of the 90S small subunit pre-ribosome

    Qi Sun et al.
    The nearly complete architecture of the gigantic 90S precursor of small ribosomal subunit is determined by cryo-EM.

    Transcriptional networks specifying homeostatic and inflammatory programs of gene expression in human aortic endothelial cells

    Nicholas T Hogan et al.
    An integrative genome-wide approach supports a direct and collaborative role of ETS and AP-1 transcription factors in maintaining endothelial cell-specific and anti-inflammatory gene expression programs.
