    Ovaries absent links dLsd1 to HP1a for local H3K4 demethylation required for heterochromatic gene silencing

    Fu Yang et al.
    A Drosophila fertility gene is identified that acts as a linker between HP1a and local H3K4 demethylation during HP1a-mediated gene silencing that is required for ovary development and transposon silencing..

    Multi-protein bridging factor 1(Mbf1), Rps3 and Asc1 prevent stalled ribosomes from frameshifting

    Jiyu Wang et al.
    An eukaryotic specific system cooperates with the ribosome quality control pathway to maintain the reading frame during translation of slowly translated sequences.

    Human embryonic lung epithelial tips are multipotent progenitors that can be expanded in vitro as long-term self-renewing organoids

    Marko Z Nikolić et al.
    Improved characterisation of human embryonic lung development highlights human-mouse differences and facilitates the development of defined culture conditions for the expansion of self-renewing, multipotent human lung epithelial progenitor cells.

    Planar cell polarity signaling coordinates oriented cell division and cell rearrangement in clonally expanding growth plate cartilage

    Yuwei Li et al.
    Through the interaction between PCP signaling and N-cadherin, oriented cell division and cell rearrangement are coordinated to establish the appropriate tissue architecture critical for limb skeletal morphogenesis.

    Essential role for SUN5 in anchoring sperm head to the tail

    Yongliang Shang et al.
    SUN5 is essential for the tight junction between sperm head and the head-tail coupling apparatus, and is the main cause of human acephalic spermatozoa syndrome.

    Spatiotemporal regulation of autophagy during Caenorhabditis elegans aging

    Jessica T Chang et al.
    Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.

    Type XVII collagen coordinates proliferation in the interfollicular epidermis

    Mika Watanabe et al.
    Type XVII collagen, a transmembranous protein in basal keratinocytes, suppresses interfollicular epidermal proliferation in neonatal and aged skin, and helps rejuvenate epidermis.

    Doc2B acts as a calcium sensor for vesicle priming requiring synaptotagmin-1, Munc13-2 and SNAREs

    Sébastien Houy et al.
    Doc2B functions in two distinct vesicle priming steps; membrane localization occludes upstream Ca2+-dependent priming, whereas Ca2+-binding and interaction with synaptotagmin-1, SNAREs, and Munc13-2 are involved in downstream priming, which makes vesicles readily releasable.

    Ribosomal mutations promote the evolution of antibiotic resistance in a multidrug environment

    James E Gomez et al.
    Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.

    TP53 drives invasion through expression of its Δ133p53β variant

    Gilles Gadea et al.
    Clinical analysis corroborated with experimental data demonstrate that Δ133p53β, a naturally occurring isoform of p53 protein, induces a pro-metastatic program and is a clinical indicator of metastasis, independently of TP53 mutation status.
