    Co-targeting myelin inhibitors and CSPGs markedly enhances regeneration of GDNF-stimulated, but not conditioning-lesioned, sensory axons into the spinal cord

    Jinbin Zhai, Hyukmin Kim ... Young-Jin Son
    Myelin-associated inhibitors and chondroitin sulfate proteoglycans are not the primary mechanism stopping sensory axons regenerating into the spinal cord, although their removal can markedly enhance regeneration when combined with an intervention that elevates axon growth capacity sufficiently robustly.

    Genetic dissection of Down syndrome-associated congenital heart defects using a new mouse mapping panel

    Eva Lana-Elola, Sheona Watson-Scales ... Victor LJ Tybulewicz
    A panel of seven new mouse strains with chromosomal duplications is used to identify a minimal genetic region required in three copies to cause congenital heart defects typical of human Down syndrome.

    Mutations in L-type amino acid transporter-2 support SLC7A8 as a novel gene involved in age-related hearing loss

    Meritxell Espino Guarch, Mariona Font-Llitjós ... Virginia Nunes
    SLC7A8 a neutral amino acid transporter has a key role in the maintenance of hearing during aging and its absence causes early onset of hearing loss.

    SORBS2 is a genetic factor contributing to cardiac malformation of 4q deletion syndrome patients

    Fei Liang, Bo Wang ... Zhen Zhang
    Combined evidence of human genetics, in vitro cardiomyocyte differentiation, and mouse model indicates that SORBS2 is a regulator of second heart field development and its deficiency causes seemingly opposite atrial septal defects.

    Trabid patient mutations impede the axonal trafficking of adenomatous polyposis coli to disrupt neurite growth

    Daniel Frank, Maria Bergamasco ... Hoanh Tran
    A novel DUB-regulated mechanism controls polarized axon growth and guidance.

    Defective AMH signaling disrupts GnRH neuron development and function and contributes to hypogonadotropic hypogonadism

    Samuel Andrew Malone, Georgios E Papadakis ... Paolo Giacobini
    Mouse in vivo and in vitro analysis and human genetic screening highlight the role of anti-Müllerian hormone (AMH) signaling in GnRH neuronal development and function, and identify mutations in AMH and AMHR2 in CHH patients.

    The LRR-TM protein PAN-1 interacts with MYRF to promote its nuclear translocation in synaptic remodeling

    Shi-Li Xia, Meng Li ... Yingchuan B Qi
    Identified as a binding factor of transcription factor MYRF, the LRR-TM protein PAN-1 promotes the cell-membrane localization and nuclear translocation of MYRF, which drives synaptic rewiring in Caenorhabditis elegans.

    A simple and effective F0 knockout method for rapid screening of behaviour and other complex phenotypes

    François Kroll, Gareth T Powell ... Jason Rihel
    Zebrafish knockouts can be generated in a few hours directly from wild-type eggs and are suitable for studying continuous traits, including behaviour.

    Variable paralog expression underlies phenotype variation

    Raisa Bailon-Zambrano, Juliana Sucharov ... James T Nichols
    Within populations, there is standing variation in paralog expression levels, paralog expression levels are heritable, and variation in paralog expression can modify the phenotypes associated with mutation of one of the paralogs.

    Fgf4 maintains Hes7 levels critical for normal somite segmentation clock function

    Matthew J Anderson, Valentin Magidson ... Mark Lewandoski
    Quantification of fluorescently labeled mRNAs reveals that Fgf4 regulates Notch oscillations in the segmentation clock that controls somitogenesis.
