    A light-gated transcriptional recorder for detecting cell-cell contacts

    Kelvin F Cho, Shawn M Gillespie ... Alice Y Ting
    TRACC (Transcriptional Readout Activated by Cell-cell Contacts) is an engineered molecular tool that detects and records cell-cell contacts in mammalian systems.

    A neural progenitor mitotic wave is required for asynchronous axon outgrowth and morphology

    Jérôme Lacoste, Hédi Soula ... Sophie Louvet-Vallée
    Timing of neural precursor cells division controls the order of development of sensory neurons, which in turn determines their axon terminal pattern and ultimately fly behaviour.

    Distinct and diverse chromatin proteomes of ageing mouse organs reveal protein signatures that correlate with physiological functions

    Giorgio Oliviero, Sergey Kovalchuk ... Ole N Jensen
    Quantitative proteomics reveals the diversity and heterogeneity of nuclear proteomes in mammalian organs and identifies the molecular features of ageing.

    The transcription factor Xrp1 orchestrates both reduced translation and cell competition upon defective ribosome assembly or function

    Marianthi Kiparaki, Chaitali Khan ... Nicholas E Baker
    Ribosomal protein mutations, mutations that affect ribosomal RNA synthesis, or function of the mature ribosome, trigger a transcriptional response mediated by Xrp1 expression which reduces cellular translation via eIF2-alpha phosphorylation and renders cells liable to competition with wild-type neighbors.

    The out-of-field dose in radiation therapy induces delayed tumorigenesis by senescence evasion

    Erwan Goy, Maxime Tomezak ... Corinne Abbadie
    Irradiation of normal human fibroblasts and mice in conditions mimicking standard external X-ray radiotherapy protocols highlights that noncancerous cells surrounding the planning target volume accumulate DNA single-strand breaks but almost no double-strand breaks, putting them in a pre-cancerous senescent state.

    In vivo transcriptomic profiling using cell encapsulation identifies effector pathways of systemic aging

    Omid Mashinchian, Xiaotong Hong ... C Florian Bentzinger
    Cell encapsulation-based transcriptional profiling using myogenic progenitors reveals that long-range factors in the aged systemic environment induce a wide range of signaling pathways in a niche-independent manner.

    Tom70-based transcriptional regulation of mitochondrial biogenesis and aging

    Qingqing Liu, Catherine E Chang ... Chuankai Zhou
    Tom70 connects the mitochondrial import to the nuclear transcriptional activity of mitochondrial proteins and controls mitochondrial biogenesis defects during aging.

    SOX4 facilitates PGR protein stability and FOXO1 expression conducive for human endometrial decidualization

    Pinxiu Huang, Wenbo Deng ... Shuangbo Kong
    A biochemical approach shows that SOX4 guaranteed the PGR protein stability through repressing the ubiquitin E3 ligase HERC4, to make the stroma cell conducive for response to progesterone and decidualization.

    C-type natriuretic peptide facilitates autonomic Ca2+ entry in growth plate chondrocytes for stimulating bone growth

    Yuu Miyazaki, Atsuhiko Ichimura ... Hiroshi Takeshima
    Membrane potential adjustment required for growth plate chondrocytic signal conversion from cGMP to Ca2+ influx toward long bone outgrowth.

    Activation of the CaMKII-Sarm1-ASK1-p38 MAP kinase pathway protects against axon degeneration caused by loss of mitochondria

    Chen Ding, Youjun Wu ... Marc Hammarlund
    Axon degeneration due to loss of mitochondria is suppressed by CaMKII activity and MAP kinase signaling.
