    Consistent global structures of complex RNA states through multidimensional chemical mapping

    Clarence Yu Cheng, Fang-Chieh Chou ... Rhiju Das
    A multidimensional chemical mapping strategy enables confident determination of the structures of non-coding RNAs at 1-nm resolution, including previously intractable riboswitch and human regulon states.

    FoxP2 isoforms delineate spatiotemporal transcriptional networks for vocal learning in the zebra finch

    Zachary Daniel Burkett, Nancy F Day ... Stephanie A White
    Basal ganglia gene coexpression patterns shift across the sensorimotor critical period for vocal learning.

    Crosstalk between nitric oxide and retinoic acid pathways is essential for amphioxus pharynx development

    Filomena Caccavale, Giovanni Annona ... Salvatore D'Aniello
    Previously undescribed morphogenetic and developmental mechanisms unravel that the cooperation of two ancient signaling pathways, nitric oxide and retinoic acid, is essential to build a chordate embryo.

    Regenerative neurogenic response from glia requires insulin-driven neuron-glia communication

    Neale J Harrison, Elizabeth Connolly ... Alicia Hidalgo
    Neuronal Ia-2 and glial Kon coordinate an injury-response insulin relay that restores glial cell populations and induces neural stem cells from glia, enabling central nervous system regeneration.

    A novel, ataxic mouse model of ataxia telangiectasia caused by a clinically relevant nonsense mutation

    Harvey Perez, May F Abdallah ... Paul J Mathews
    Progressive changes in Purkinje neuron perturbations and overall cerebellar atrophy correlate for the first time with the development of an overt loss of motor function in a novel mouse model of Ataxia Telangiectasia.

    Stem-loop and circle-loop TADs generated by directional pairing of boundary elements have distinct physical and regulatory properties

    Wenfan Ke, Miki Fujioka ... James B Jaynes
    Boundary:boundary pairing generates either stem-loop or circle-loop TADs, and these loop topologies differ in how they impact chromosome structure and genetic activities.

    Chromatin-associated RNA sequencing (ChAR-seq) maps genome-wide RNA-to-DNA contacts

    Jason C Bell, David Jukam ... Aaron F Straight
    ChAR-seq is a massively parallelized de novo RNA mapping assay, which is capable of generating hundreds to thousands of RNA-binding maps with no a priori knowledge of target RNAs.

    The Drosophila ZAD zinc finger protein Kipferl guides Rhino to piRNA clusters

    Lisa Baumgartner, Dominik Handler ... Julius Brennecke
    Kipferl, a ZAD zinc finger protein from Drosophila, determines the chromatin binding specificity of the heterochromatin protein variant Rhino, defining piRNA clusters and preventing Rhino sequestration by selfish Satellite repeats.

    Estradiol elicits distinct firing patterns in arcuate nucleus kisspeptin neurons of females through altering ion channel conductances

    Jian Qiu, Margaritis Voliotis ... Martin J Kelly
    Kiss1ARH neurons transition from synchronous to burst firing under preovulatory levels of E2, causing a shift from peptidergic to glutamatergic transmission that drives the GnRH surge through enhanced glutamate neurotransmission.

    Nova proteins direct synaptic integration of somatostatin interneurons through activity-dependent alternative splicing

    Leena Ali Ibrahim, Brie Wamsley ... Gordon Fishell
    RNA sequencing and conditional Nova mutants reveal that Nova protein function is necessary for activity-dependent alternative splicing of synaptic genes within somatostatin cortical interneurons and regulates its afferent and efferent connectivity.
