    Anisotropic organization of circumferential actomyosin characterizes hematopoietic stem cells emergence in the zebrafish

    Mylene Lancino et al.
    Emergence of hematopoietic stem cells from an aortic component is a unique phenomenon of cell extrusion, with no equivalent in cell biology, and which is adapted to environmental constraints exerted by endothelial cells and hemodynamics forces.

    Human axial progenitors generate trunk neural crest cells in vitro

    Thomas JR Frith et al.
    Pluripotent stem cell differentiation provides insight into how neural crest subtypes of distinct axial identity are patterned in human embryos.

    Single-particle cryo-EM structure of a voltage-activated potassium channel in lipid nanodiscs

    Doreen Matthies et al.
    The structure of a voltage-activated potassium channel in lipid nanodiscs solved using cryo-electron microscopy is similar to previous X-ray structures, and provides insights into the mechanism of C-type inactivation.

    Effects of spinal cord stimulation on postural control in Parkinson's disease patients with freezing of gait

    Andrea Cristina de Lima-Pardini et al.
    High-frequency stimulation of the upper thoracic spinal cord corrects anticipatory postural adjustments and improving gait efficiency and inhibiting freezing of gait episodes in advanced Parkinson's disease.

    Stimulus vignetting and orientation selectivity in human visual cortex

    Zvi N Roth et al.
    Functional MRI measurements of orientation reflect coarse-scale biases that are wholly determined by second-order interactions between the stimulus aperture and the underlying orientation.

    Wnt/PCP controls spreading of Wnt/β-catenin signals by cytonemes in vertebrates

    Benjamin Mattes et al.
    Wnt signaling regulates its effective signaling range by controlling Wnt ligand transport on signaling filopodia within vertebrate tissues.

    KCNE1 tunes the sensitivity of KV7.1 to polyunsaturated fatty acids by moving turret residues close to the binding site

    Johan E Larsson et al.
    An auxiliary subunit alters the effect of a family of small-molecule openers on a voltage-gated potassium channel by inducing structural re-arrangements that promote protonation of the drug molecule.

    Pharmacologic ATF6 activating compounds are metabolically activated to selectively modify endoplasmic reticulum proteins

    Ryan Paxman et al.
    The small molecule, 147, is a pro-drug that preferentially activates ATF6 signaling through a mechanism involving localized metabolic activation and selective covalent modification of ER resident proteins involved in regulating ATF6 activity.

    Loss of Fam60a, a Sin3a subunit, results in embryonic lethality and is associated with aberrant methylation at a subset of gene promoters

    Ryo Nabeshima et al.
    Fam60a, a component of the Sin3a complex, is required for embryonic development and regulates methylation at a subset of gene promoters.
