    Oxytocin improves behavioral and electrophysiological deficits in a novel Shank3-deficient rat

    Hala Harony-Nicolas, Maya Kay ... Joseph D Buxbaum
    The production, validation and study of a novel rat model for Phelan McDermid Syndrome shows an ameliorative effect of oxytocin on both social and attentional deficits.

    Shank3 modulates sleep and expression of circadian transcription factors

    Ashley M Ingiosi, Hannah Schoch ... Lucia Peixoto
    Shank3, a high confidence autism gene candidate, may be a key component of the mechanisms underlying sleep problems in autism.

    Shank promotes action potential repolarization by recruiting BK channels to calcium microdomains

    Luna Gao, Jian Zhao ... Joshua M Kaplan
    Shank promotes functional coupling between CaV1 calcium channels and BK potassium channels.

    Shank is a dose-dependent regulator of Cav1 calcium current and CREB target expression

    Edward Pym, Nikhil Sasidharan ... Joshua M Kaplan
    Changes in Shank gene dosage alter voltage-activated calcium current and calcium-activated gene expression in a manner that parallels the effects of human Shank copy number variation on psychiatric disease risk.

    Dysregulation of mTOR signaling mediates common neurite and migration defects in both idiopathic and 16p11.2 deletion autism neural precursor cells

    Smrithi Prem, Bharati Dev ... Emanuel DiCicco-Bloom
    Alterations in mTOR signaling drive similar dysregulations in the critical mid-fetal neurodevelopmental processes of neurite outgrowth and cell migration in two distinct subsets of autism, idiopathic and 16p11.2 deletion.

    Cerebellar associative sensory learning defects in five mouse autism models

    Alexander D Kloth, Aleksandra Badura ... Samuel S-H Wang
    Five mouse models of autism show deficits in delay eyeblink conditioning, a form of split-second sensory learning that involves the cerebellum, a frequent site of disruption in autistic brains.

    Linking mPFC circuit maturation to the developmental regulation of emotional memory and cognitive flexibility

    Cassandra B Klune, Benita Jin, Laura A DeNardo
    An analysis of recent literature advances novel hypotheses and suggests new experimental approaches in order to build an integrated understanding of prefrontal neural architecture and behavioral repertoires during development.

    Sex differences in cerebellar synaptic transmission and sex-specific responses to autism-linked Gabrb3 mutations in mice

    Audrey A Mercer, Kristin J Palarz ... Indira M Raman
    Male and female mice differ in basal cerebellar physiology, including the magnitude of synaptic excitation by metabotropic glutamate receptors, kinetics of synaptic inhibition, intrinsic properties, and responses to autism-linked mutations.

    FMRP has a cell-type-specific role in CA1 pyramidal neurons to regulate autism-related transcripts and circadian memory

    Kirsty Sawicka, Caryn R Hale ... Robert B Darnell
    Identifying FMRP-bound mRNAs in hippocampal CA1 pyramidal neurons reveals cell-type specific regulation of autism-candidate and circadian mRNAs and FMRP-mediated control of memory across the circadian cycle.
    1. Neuroscience

    Autism-associated SHANK3 missense point mutations impact conformational fluctuations and protein turnover at synapses

    Michael Bucher, Stephan Niebling ... Marina Mikhaylova
    Autism-associated SHANK3 missense mutations result in differential protein folding, stability, and intramolecular dynamics affecting its turnover at the synapse.
