  • RhoA determines lineage fate of mesenchymal stem cells by modulating
           CTGF–VEGF complex in extracellular matrix

    • Authors: Changjun Li, Gehua Zhen, Yu Chai, Liang Xie, Janet L. Crane, Emily Farber, Charles R. Farber, Xianghang Luo, Peisong Gao, Xu Cao, Mei Wan
      Abstract: It is unclear what regulates the fate of mesenchymal stem cells (MSCs) in arterial repair following injury. Here, the authors show that MSC differentiation following injury is triggered by RhoA which in turn stimulates the release of connective tissue growth factor and vascular endothelial growth factor.

  • Converging flow and anisotropy cause large-scale folding in Greenland's
           ice sheet

    • Authors: Paul D. Bons, Daniela Jansen, Felicitas Mundel, Catherine C. Bauer, Tobias Binder, Olaf Eisen, Mark W. Jessell, Maria-Gema Llorens, Florian Steinbach, Daniel Steinhage, Ilka Weikusat
      Abstract: A range of mechanisms has been proposed for large-scale folding in polar ice sheets. Here, using new three-dimensional reconstructions of such folds in the onset region of the Greenland Petermann Glacier, the authors show that these formed due to flow convergence and the high mechanical anisotropy of ice.

  • DNMT3B isoforms without catalytic activity stimulate gene body methylation
           as accessory proteins in somatic cells

    • Authors: Christopher E. Duymich, Jessica Charlet, Xiaojing Yang, Peter A. Jones, Gangning Liang
      Abstract: De novo DNA methylation is carried out by DNA methyltransferase DNMT3A/B, although DNMT3B isoforms without active catalytic domains are widely expressed. Here, the authors show that DNMT3B isoforms stimulate gene body methylation and re-methylation independently of the isoforms' catalytic activity.

      Abstract: Defaunation is linked to the decline of tree species that depend on large animals for seed dispersal, but it is unclear if this affects carbon storage. Here the authors show that defaunation effects on carbon storage vary across continents, driven by relationships between seed dispersal strategies and adult tree size.

  • Phosphotransferase-dependent accumulation of (p)ppGpp in response to
           glutamine deprivation in Caulobacter crescentus

    • Abstract: The small molecule (p)ppGpp is commonly produced by bacteria as a signal of nutrient starvation. Here, Ronneau et al . show that (p)ppGpp accumulation in the model bacterium Caulobacter crescentus is modulated by a nitrogen-related phosphotransferase system in response to glutamine deprivation.

  • miRNA863-3p sequentially targets negative immune regulator ARLPKs and
           positive regulator SERRATE upon bacterial infection

    • Authors: Dongdong Niu, Yifan E. Lii, Padmanabhan Chellappan, Lei Lei, Karl Peralta, Chunhao Jiang, Jianhua Guo, Gitta Coaker, Hailing Jin
      Abstract: Small RNA plays an important role in regulating the plant defence against bacterial pathogens. Here the authors propose that miR863-3p acts to fine-tune the timing of defence responses by sequentially silencing negative and positive regulators of the plant immune response.

  • The obesity-induced transcriptional regulator TRIP-Br2 mediates visceral
           fat endoplasmic reticulum stress-induced inflammation

    • Abstract: Visceral and subcutaneous fat are associated with different metabolic risk, but mediators of such depot specific effects are not very well known. Here the authors identify the transcriptional regulator, TRIP-Br2, as a regulator of endoplasmic reticulum (ER) stress-induced inflammatory responses specifically in visceral fat.

  • Mechanical cell competition kills cells via induction of lethal p53 levels

    • Abstract: Cell competition is a quality control mechanism to eliminate unfit cells. Here the authors show that physical compaction of less fit cells surrounded by healthy neighbours leads to increased expression of tumour suppressor p53 in the compacted cells, causing cell death.

  • Arabidopsis PROTEASOME REGULATOR1 is required for auxin-mediated
           suppression of proteasome activity and regulates auxin signalling

    • Authors: Bao-Jun Yang, Xin-Xin Han, Lin-Lin Yin, Mei-Qing Xing, Zhi-Hong Xu, Hong-Wei Xue
      Abstract: Plant responses to auxin require proteasome-mediated degradation of Aux/IAA transcriptional repressor proteins. Here, Yang et al . show that auxin suppresses proteasome activity in a manner dependent on the proteasome regulator PTRE1 and propose a mechanism for fine tuning Aux/IAA homoeostasis.

      Abstract: When grown in the lab, Mycobacterium tuberculosis can form pellicle biofilms. Here, Trivedi et al . show that thiol reductive stress (induced by dithiothreitol) triggers rapid formation of thicker biofilms containing cellulose as well as antibiotic-tolerant, metabolically active bacteria.

  • Host gene constraints and genomic context impact the expression and
           evolution of human microRNAs

    • Abstract: Recent miRNAs tend to emerge within coding genes. Here, by analysing miRNA expression data from six species and comparing genomes from 13 species, the authors report that host genes may provide stronger expression constraints to intragenic miRNAs in the long run.

  • Enhanced nonlinear interactions in quantum optomechanics via mechanical
           amplification

    • Authors: Marc-Antoine Lemonde, Nicolas Didier, Aashish A. Clerk
      Abstract: Optomechanics harnesses the interaction between mechanical resonators and light, but weak matter–single-photon interactions limit studies to the linear regime. Here, the authors show that the interaction can be enhanced by modulating the spring constant of the resonator.

      Abstract: Use of general linear mixed models (GLMMs) in genetic variance analysis can quantify the relative contribution of additive effects from genetic variation on a given trait. Here, Jonathan Mosley and colleagues apply GLMM in a phenome-wide analysis and show that genetic variations in the HLA region are associated with 44 phenotypes, 5 phenotypes which were not previously reported in GWASes.

  • Retroviral intasomes search for a target DNA by 1D diffusion which rarely
           results in integration

    • Authors: Nathan D. Jones, Miguel A. Lopez Jr, Jeungphill Hanne, Mitchell B. Peake, Jong-Bong Lee, Richard Fishel, Kristine E. Yoder
      Abstract: Retroviral Integration into the host DNA is a rare event with evidence suggesting that it relies on DNA topology and sequence. Here the authors present single molecule evidence that shows the retroviral integration machinery vigorously scans the target DNA by 1D-diffusion but infrequently integrates.

      Abstract: The extent to which mammals and other vertebrates share similar mechanisms of tissue regeneration is unclear. Here, the authors use an ear punch assay in spiny mice, which regenerate fully, to show blastema formation and mesenchymal cell proliferation as cell cycle regulators p21 and p27 remain cytoplasmic.

           unconventional protein secretion

    • Authors: Jinsei Jung, Jiyoon Kim, Shin Hye Roh, Ikhyun Jun, Robert D. Sampson, Heon Yung Gee, Jae Young Choi, Min Goo Lee
      Abstract: Mutations in pendrin, a plasma membrane transporter, lead to Pendred syndrome, which is associated with hearing loss. Here, Jung et al . show that cell-surface expression of a mutated form of pendrin can be restored by blocking ER-to-Golgi traffic and triggering a DNAJC14 dependent unconventional secretion pathway.
