    The sterol-responsive RNF145 E3 ubiquitin ligase mediates the degradation of HMG-CoA reductase together with gp78 and Hrd1

    Sam A Menzies et al.
    CRISPR/Cas9 genome-wide screens using sterol-sensitive endogenous HMG-CoA reductase (HMGCR) reporter identify the sterol-responsive RNF145 and gp78 as independently responsible for sterol-accelerated degradation of HMGCR, the rate-limiting enzyme of cholesterol biosynthesis.

    A new view of transcriptome complexity and regulation through the lens of local splicing variations

    Jorge Vaquero-Garcia et al.
    New methods reveal that complex local splicing variations are more prevalent in animals than previously appreciated, and demonstrate that local splicing variations are relevant for studies of development, gene regulation and neurodegenerative diseases.

    An incoherent feedforward loop facilitates adaptive tuning of gene expression

    Jungeui Hong et al.
    The architecture of a gene regulatory network determines the effect of evolutionary changes in transcription factor binding.

    Alternative RNA splicing in the endothelium mediated in part by Rbfox2 regulates the arterial response to low flow

    Patrick A Murphy et al.
    Transcriptome analysis reveals an alternative splicing program induced in the arterial endothelium under low-flow inflammatory conditions by platelet and macrophage recruitment and dependent upon the RNA-binding splice factor Rbfox2.

    Ecological feedback in quorum-sensing microbial populations can induce heterogeneous production of autoinducers

    Matthias Bauer et al.
    Quorum sensing enables heterogeneous production of autoinducers in microbial populations, suggesting an alternative mechanism to stochastic gene expression in bistable gene-regulatory circuits to control phenotypic heterogeneity.

    Tissue-specific regulation of BMP signaling by Drosophila N-glycanase 1

    Antonio Galeone et al.
    N-glycanase 1 is required for a BMP autoregulatory loop in the visceral mesoderm and for intestinal development in Drosophila.

    Evolutionary changes in transcription factor coding sequence quantitatively alter sensory organ development and function

    Simon Weinberger et al.
    The coding sequences of a very highly conserved family of neurogenic transcription factors from different species have evolved to generate proteins that have different life times causing them to display quantitatively different neural induction potentials.
