    Guanidine hydrochloride reactivates an ancient septin hetero-oligomer assembly pathway in budding yeast

    Courtney R Johnson et al.
    A naturally-occurring small molecule acts as a chemical chaperone in vivo to alter the folding of a budding yeast septin and promote an oligomerization pathway that was lost during evolution.

    PLZF targets developmental enhancers for activation during osteogenic differentiation of human mesenchymal stem cells

    Shuchi Agrawal Singh et al.
    A key transcription-factor for osteogenic differentiation, PLZF, acts as a transcriptional activator by binding to active developmental enhancers and facilitates mediator recruitment, but is not involved in enhancer looping.

    Cryo-EM structures and functional properties of CALHM channels of the human placenta

    Katarzyna Drożdżyk et al.
    Members of the calcium homeostasis modulator family expressed in the placenta form large channels with unknown activation properties that harbor a lipid bilayer on the inside of a cylindrical pore.

    CSF1R blockade induces macrophage ablation and results in mouse choroidal vascular atrophy and RPE disorganization

    Xiao Yang et al.
    Vascular degeneration of the choroid and RPE disorganization were associated with pharmacological macrophage ablation, indicating that insufficiency of macrophage function may be a mechanism underlying age- and AMD-associated pathology.

    An alternatively spliced, non-signaling insulin receptor modulates insulin sensitivity via insulin peptide sequestration in C. elegans

    Bryan A Martinez et al.
    A truncated, non-signaling insulin receptor regulates insulin sensitivity in the nematode C. elegans by sequestering insulin peptides and preventing their interaction with full length receptors.

    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst et al.
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    Metabolic and non-metabolic liver zonation is established non-synchronously and requires sinusoidal Wnts

    Ruihua Ma et al.
    Mouse genetic approaches show that multiple Wnt endothelial sources orchestrate the spatiotemporal distribution of hepatocyte functions during liver maturation and respecify metabolic zonation during liver repair.

    Gating and selectivity mechanisms for the lysosomal K+ channel TMEM175

    SeCheol Oh et al.
    Structures of the non-canonical potassium channel TMEM175 in open and closed states reveal unique mechanisms for channel gating and the selective permeation of K+ ions.

    Stxbp1/Munc18-1 haploinsufficiency impairs inhibition and mediates key neurological features of STXBP1 encephalopathy

    Wu Chen et al.
    Two genetically distinct Stxbp1 haploinsufficiency mouse models exhibit seizures and impairments in cognitive, psychiatric, and motor functions, representing robust preclinical models of STXBP1 encephalopathy with both construct and face validity.

    Combinatorial chromatin dynamics foster accurate cardiopharyngeal fate choices

    Claudia Racioppi et al.
    ATAC-seq, CRISPR/Cas9 mutagenesis, reporter and gene expression assays revealed dynamic chromatin accessibility profiles governing differential gene expression during heart vs. pharyngeal muscle fate choices in the powerful chordate model Ciona.
