    MYC regulates ribosome biogenesis and mitochondrial gene expression programs through its interaction with host cell factor–1

    Tessa M Popay et al.
    Interaction of oncoprotein transcription factor MYC with chromatin-associated protein host cell factor–1 controls expression of genes important for ribosome biogenesis and mitochondrial vigor, loss of which promotes tumor regression.

    Transient protein-protein interactions perturb E. coli metabolome and cause gene dosage toxicity

    Sanchari Bhattacharyya et al.
    Weak yet highly species-specific protein-protein interactions enhance the activity of metabolically related enzymes in bacteria at endogenous conditions, but also mean that overexpression of one partner leads to permanent non-physiological complexes and gene dosage toxicity.

    Genetic interactions affecting human gene expression identified by variance association mapping

    Andrew Anand Brown et al.
    Multiple replicated examples of epistasis affecting gene expression in humans are identified, some explaining a substantial proportion of the variation in expression.

    SOX2 O-GlcNAcylation alters its protein-protein interactions and genomic occupancy to modulate gene expression in pluripotent cells

    Samuel A Myers et al.
    A post-translational modification called O-GlcNAcylation modulates the activity of the SOX2 transcription factor in pluripotent stem cells.

    Interactions with RNA direct the Polycomb group protein SCML2 to chromatin where it represses target genes

    Roberto Bonasio et al.
    The Polycomb group protein SCML2 contributes to the assembly and gene silencing function of Polycomb Repressive Complex 1 (PRC1) and requires an RNA-binding region to reach chromatin targets.

    Psychosocial experiences modulate asthma-associated genes through gene-environment interactions

    Justyna A Resztak et al.
    Psychosocial environments modulate genetic risk of asthma and other allergic diseases through altered peripheral blood gene expression.

    Social interaction-induced activation of RNA splicing in the amygdala of microbiome-deficient mice

    Roman M Stilling et al.
    Social-interaction impairment in germ-free mice is associated with a markedly altered transcriptional response to social novelty in the amygdala, as characterised by replacement of upregulation of common stimulus-induced pathways with upregulation of the splicing machinery.

    Cdon mutation and fetal alcohol converge on Nodal signaling in a mouse model of holoprosencephaly

    Mingi Hong et al.
    A combination of window-of-sensitivity, genetic, and in vitro findings illuminate mechanisms of gene–environment interaction in a multifactorial model of a common birth defect.

    Plant–necrotroph co-transcriptome networks illuminate a metabolic battlefield

    Wei Zhang et al.
    Simultaneously measuring the transcriptomes of both a host plant and fungal pathogen, co-transcriptomics, identified diverse, dynamic and independent communication mechanisms conveying information between the two organisms via discrete gene modules.

    Simple biochemical features underlie transcriptional activation domain diversity and dynamic, fuzzy binding to Mediator

    Adrian L Sanborn et al.
    Transcriptional activation domains achieve rapid, dynamic, specific interaction with Mediator through binding of an unstructured peptide to multiple hydrophobic surfaces without particular amino acid side chain interactions.
