    Evolutionary expansion of apical extracellular matrix is required for the elongation of cells in a novel structure

    Sarah Jacquelyn Smith et al.
    A new morphological structure evolved through extreme changes in cell height requires novel connections to an extracellular matrix network, which predates the origin of structure.

    Retrocopying expands the functional repertoire of APOBEC3 antiviral proteins in primates

    Lei Yang et al.
    Genomes take advantage of the gene-duplicating ability of retroelements to birth novel innate immune defense genes.

    MeCP2 in cholinergic interneurons of nucleus accumbens regulates fear learning

    Ying Zhang et al.
    Robust fear learning deficits and decreased tonic activity of NAc cholinergic interneurons caused by depletion of MeCP2 could be attributed to an elevation in α2-containing GABAA receptors.

    ER-luminal [Ca2+] regulation of InsP3 receptor gating mediated by an ER-luminal peripheral Ca2+-binding protein

    Horia Vais et al.
    Calcium release from the endoplasmic reticulum through the IP3 receptor ion channel is strongly regulated by a calcium-binding protein in the lumen of the endoplasmic reticulum.

    Bmal1 integrates mitochondrial metabolism and macrophage activation

    Ryan K Alexander et al.
    Macrophage Bmal1 controls the timing of the glycolytic to oxidative metabolism transition that dictates the extent of Hif-1a activation and the associated inflammatory response.

    Live-cell single particle imaging reveals the role of RNA polymerase II in histone H2A.Z eviction

    Anand Ranjan et al.
    Histone variant H2A.Z is deposited near transcription start sites by the chromatin remodeler SWR1 and seems to be removed by RNA polymerase II at an early stage of transcription elongation.

    Axon-dependent expression of YAP/TAZ mediates Schwann cell remyelination but not proliferation after nerve injury

    Matthew Grove et al.
    YAP and TAZ, potent concoproteins and therapeutic targets in cancer therapy, are essential for Schwann cells to support peripheral nerve regeneration.

    Lin28a/let-7 pathway modulates the Hox code via Polycomb regulation during axial patterning in vertebrates

    Tempei Sato et al.
    Genetic analyses reveal that the loss of Lin28a causes axial shortening with mild skeletal transformations via decreased PRC1 at Hox genes, establishing a new pathway in the “Hox code.”.
