    In situ single particle classification reveals distinct 60S maturation intermediates in cells

    Bronwyn A Lucas, Kexin Zhang ... Nikolaus Grigorieff
    Comparing the relative similarity of cellular molecules to alternate templates allows classification of related complexes in the cell using fewer particles than needed for 3D classification and is more practicable for low abundance complexes.

    Functional dynamic genetic effects on gene regulation are specific to particular cell types and environmental conditions

    Anthony S Findley, Alan Monziani ... Francesca Luca
    Investigation of dynamic gene regulation across cell types and environments reveals new GxE regulatory loci that are important for disease.

    Yap1 safeguards mouse embryonic stem cells from excessive apoptosis during differentiation

    Lucy LeBlanc, Bum-Kyu Lee ... Jonghwan Kim
    During ES cell differentiation, Yap1 directly regulates apoptosis-related genes like Bcl-2 and Mcl-1 to attenuate apoptosis and promote cell survival to allow for successful cell fate changes.

    Characterization of caffeine response regulatory variants in vascular endothelial cells

    Carly Boye, Cynthia A Kalita ... Francesca Luca
    Caffeine modulates the genetic risk for cardiovascular disease through changes in target gene expression, likely due to regulation of transcription factor binding.

    Baited reconstruction with 2D template matching for high-resolution structure determination in vitro and in vivo without template bias

    Bronwyn A Lucas, Benjamin A Himes, Nikolaus Grigorieff
    2D template matching enables a streamlined single-particle cryogenic electron microscopy workflow that can be used to discover new high-resolution structural features in molecules and complexes, such as bound ligands and drugs.

    The expression of established cognitive brain states stabilizes with working memory development

    David Florentino Montez, Finnegan J Calabro, Beatriz Luna
    The excessive behavioral variability associated with adolescence is the result of greater instability of widespread or global gain signals which produces greater variability in the amplitude of expression of whole-brain states of task-related activity.

    Axonal T3 uptake and transport can trigger thyroid hormone signaling in the brain

    Federico Salas-Lucia, Csaba Fekete ... Antonio C Bianco
    T3 is taken up by axonal termini and is retrogradely transported into endosomal vesicles to the cell nucleus, where it regulates gene expression.
    1. Neuroscience

    Reconfiguration of functional brain networks and metabolic cost converge during task performance

    Andreas Hahn, Michael Breakspear ... Luca Cocchi
    Cognitive performance is supported by symbiotic metabolic and neuro-vascular responses in task-specific brain networks.

    Measurements and models of electric fields in the in vivo human brain during transcranial electric stimulation

    Yu Huang, Anli A Liu ... Lucas C Parra
    Direct in-vivo measurements in the human brain test validity of detailed computational models of trancranial electric stimulation and show that electric fields in the brain are weaker than currently assumed.

    Locating macromolecular assemblies in cells by 2D template matching with cisTEM

    Bronwyn A Lucas, Benjamin A Himes ... Nikolaus Grigorieff
    2D template matching complements 3D template matching of tomograms, providing fast and specific detection of molecules in cryo-EM images of cells, as well as generating 3D reconstructions from detected targets.
