    Machine learning-assisted elucidation of CD81–CD44 interactions in promoting cancer stemness and extracellular vesicle integrity

    Erika K Ramos, Chia-Feng Tsai ... Huiping Liu
    Machine learning-assisted experiments reveal CD81 as a novel binding partner of CD44 in driving cancer stemness, tumor cell clustering, and extracellular vesicle integrity in human and mouse breast cancer.

    The structure-selective endonucleases GEN1 and MUS81 mediate complementary functions in safeguarding the genome of proliferating B lymphocytes

    Keith Conrad Fernandez, Laura Feeney ... Jayanta Chaudhuri
    A novel conditional mouse model to interrogate the requirements of structure-selective endonucleases in the development, functionality, and genome stability of B lymphocytes.

    Fuzzy supertertiary interactions within PSD-95 enable ligand binding

    George L Hamilton, Nabanita Saikia ... Mark E Bowen
    A combination of single molecule fluorescence with DMD simulations and disulfide mapping resolved the multistate structural landscape of the PSG supramodule from PSD-95, which explains how interdomain interactions within PSD-95 enable PDZ3 binding of the critical synaptic adhesion protein neuroligin.

    A visual sense of number emerges from divisive normalization in a simple center-surround convolutional network

    Joonkoo Park, David E Huber
    A set of canonical computational principles implemented in a simple feedforward neural network naturally gives rise to the network's sensitivity to numerosity and its illusory effects, providing an explanation for the ubiquity of the number sense in the animal kingdom.

    Phorbolester-activated Munc13-1 and ubMunc13-2 exert opposing effects on dense-core vesicle secretion

    Sébastien Houy, Joana S Martins ... Jakob Balslev Sørensen
    The priming protein ubMunc13-2 and Synaptotagmin-7 cooperate with phorbolesters/diacylglycerol to stimulate vesicle priming in adrenal chromaffin cells, whereas phorbolesters/diacylglycerol interacting with Munc13-1 inhibit vesicle fusion, which identifies opposing functions of these two Munc13 proteins.

    Airway basal cells show regionally distinct potential to undergo metaplastic differentiation

    Yizhuo Zhou, Ying Yang ... Wellington V Cardoso
    A combination of unbiased scRNA-sequencing and functional approaches in organoid cultures and injury-repair models in vivo reveals major heterogeneity in adult murine airway basal cells, which is established prenatally and conserved in humans.

    Functional gradients in the human lateral prefrontal cortex revealed by a comprehensive coordinate-based meta-analysis

    Majd Abdallah, Gaston E Zanitti ... Demian Wassermann
    A comprehensive meta-analysis of the neuroimaging literature reveals that the lateral prefrontal cortex of humans is mainly organized along its rostrocaudal axis according to a unimodal-to-transmodal pattern of network connectivity and a concrete-to-abstract axis of functional associations.

    Age-dependent aggregation of ribosomal RNA-binding proteins links deterioration in chromatin stability with challenges to proteostasis

    Julie Paxman, Zhen Zhou ... Nan Hao
    The interaction between rDNA instability and proteostasis stress, two major aging hallmarks, underlies single-cell aging trajectories in yeast.

    Murine endothelial serine palmitoyltransferase 1 (SPTLC1) is required for vascular development and systemic sphingolipid homeostasis

    Andrew Kuo, Antonio Checa ... Timothy Hla
    Endothelial sphingolipid biosynthesis is essential for maintaining vascular development, neovascular proliferation, non-CNS tissue sphingolipid levels, and hepatocyte response to stress.

    Evolutionary rescue of phosphomannomutase deficiency in yeast models of human disease

    Ryan C Vignogna, Mariateresa Allocca ... Gregory I Lang
    Experimental evolution of yeast models of congenital disorders of glycosylation reveals that reduction, but not loss, of phosphoglucomutase activity best compensates for impaired phosphomannomutase activity.
