    Cysteine dioxygenase 1 is a metabolic liability for non-small cell lung cancer

    Yun Pyo Kang, Laura Torrente ... Gina M DeNicola
    By increasing intracellular cysteine levels, NRF2 engages a tumor suppressive metabolic pathway mediated by cysteine dioxygenase 1.

    Epigenetic remodeling by vitamin C potentiates plasma cell differentiation

    Heng-Yi Chen, Ana Almonte-Loya ... Chan-Wang Jerry Lio
    Vitamin C supports the differentiation of antibody-secreting cells by remodeling the DNA methylome to enhance STAT3 DNA binding.

    The human leukemia virus HTLV-1 alters the structure and transcription of host chromatin in cis

    Anat Melamed, Hiroko Yaguchi ... Charles RM Bangham
    The human leukemia virus HTLV-1 causes abnormal chromatin looping in tens of thousands of infected T cell clones in each host, and abnormal host transcription both flanking the integrated provirus and at distant loci in cis.

    Ceapins are a new class of unfolded protein response inhibitors, selectively targeting the ATF6α branch

    Ciara M Gallagher, Carolina Garri ... Peter Walter
    Ceapins enable selective pharmacological inhibition of the cytoprotective transcriptional response to endoplasmic reticulum stress through ATF6α without affecting other branches of the unfolded protein response.

    Information content differentiates enhancers from silencers in mouse photoreceptors

    Ryan Z Friedman, David M Granas ... Michael A White
    Silencers and enhancers targeted by a common transcription factor in photoreceptors are distinguished by the number and diversity of binding transcription factor binding sites they contain.

    The neuron-specific IIS/FOXO transcriptome in aged animals reveals regulatory mechanisms of cognitive aging

    Yifei Weng, Shiyi Zhou ... Coleen T Murphy
    Neuron-specific sequencing of aged wild-type, daf-2, and daf-16;daf-2 mutants revealed transcriptomic changes with age, and in longevity mutants, putative neuroprotective genes are upregulated, which are required for prolonged cognitive functions.

    Small molecule proteostasis regulators that reprogram the ER to reduce extracellular protein aggregation

    Lars Plate, Christina B Cooley ... Jeffery W Kelly
    Small molecule proteostasis regulators that activate the unfolded protein response transcription factor ATF6 reduce the secretion of amyloid disease-associated proteins.

    Cell competition removes segmental aneuploid cells from Drosophila imaginal disc-derived tissues based on ribosomal protein gene dose

    Zhejun Ji, Jacky Chuen ... Nicholas Baker
    Cell competition is an important mechanism selecting against aneuploid cells.

    Reduced expression of C/EBPβ-LIP extends health and lifespan in mice

    Christine Müller, Laura M Zidek ... Cornelis F Calkhoven
    Reduced expression of a single transcription factor is sufficient to improve fitness and health at old age and increases the lifespan in female mice.

    Re-expression of SMARCA4/BRG1 in small cell carcinoma of ovary, hypercalcemic type (SCCOHT) promotes an epithelial-like gene signature through an AP-1-dependent mechanism

    Krystal Ann Orlando, Amber K Douglas ... Bernard E Weissman
    BRG1 loss drives initiation and progression in human cancers through changes in specific differentiation programs in an AP-1-dependent manner.
