“…SPNS2 also exports the S1P-mimicking FTY720-P (Fingolimod) and thereby is central to the pharmacokinetics of this drug when treating multiple sclerosis. Here, we use a combination of cryo-electron microscopy, immunofluorescence, in vitro binding and in vivo S1P export assays, and molecular dynamics simulations to probe SPNS2’s substrate binding and transport. …”

Reseeding promotes plant biomass by improving microbial community stability and soil fertility in a degraded subalpine grassland by Debao Li, Sicheng Li, Hao Chen, Jianping Wu

“…However, the mechanism understanding for the effect of multiple reseeding approaches on soil microbial community and their associated ecosystem functioning remains unclear. Here, we conducted a 3-year field reseeding experiment with eight treatments in a degraded grassland in southern China to test how the link between plant biomass and soil microbial community stability are influenced by plant community structure. …”

“…IntroductionUsually, patients with sY84 or sY86 deficiency present with azoospermia, but recent studies have shown that some males with partial AZFa deletions, including sY84 or sY86, exhibit normal fertility. Here, we reported a rare case of AZF deletion in a family, where both father and son exhibited a deletion at the sY86 site in the AZFa region and a partial deletion in the AZFc region.Methods and ResultsDetection was performed using classical multiplex polymerase chain reaction and the “Male AZF Full-region Detection” Panel, revealing specific deletions in AZFa: Yq11.21 (14,607,372–14,637,973), 30.6 kb; AZFc: Yq11.223–11.23 (25,848,831–27,120,665), 1.3 M for the father; and Yq11.223–11.23 (25,505,378–27,120,665), 1.6 M for the son. …”

Fénelon, Daniela Cota

“…The bile acid receptor Takeda G protein-coupled receptor 5 (TGR5) is expressed in the hypothalamus, where it determines some of the actions of bile acids on food intake and body weight through still poorly defined neuronal mechanisms. Here, we examined the role of TGR5 in SF1 neurons in the regulation of energy balance and glucose metabolism. …”

First evidence of transovarial transmission of Kyasanur Forest disease virus in Haemaphysalis and Rhipicephalus ticks in the wild by Sarah J. Burthe, Bhimanagoud Kumbar, Stefanie M. Schäfer, Bethan V. Purse, Abi T. Vanak, Natrajan Balakrishnan, Richard Hassall, Subhash L. Hoti, Darshan Narayanaswamy, Santoshkumar Potadar, Mujeeb Rahman, Mohammed Mudassar Chanda

“…Mathematical models predict that transovarial transmission, whereby adult female ticks pass KFDV infections to their offspring, plays an important role in the persistence of KFD, but this has not been shown in the wild. Here we set out to establish whether transovarial transmission of KFDV was occurring under natural field conditions by assessing whether host-seeking larvae were positive for KFDV. …”

Extended Reality Interventions for Health and Procedural Anxiety: Panoramic Meta-Analysis Based on Overviews of Reviews by Tom Arthur, GJ Melendez-Torres, David Harris, Sophie Robinson, Mark Wilson, Sam Vine

“…Trial effect sizes were extracted from reviews and expressed as standardized mean differences, which were entered into a 3-level generalized linear model. Here, outcomes were estimated for patients (level 1), studies (level 2), and anxiety indications (level 3), while meta-regressions explored possible influences of age, immersion, and different mechanisms of action. …”

Co-obligate symbioses have repeatedly evolved across aphids, but partner identity and nutritional contributions vary across lineages by Manzano-Marín, Alejandro, Coeur d’acier, Armelle, Clamens, Anne-Laure, Cruaud, Corinne, Barbe, Valérie, Jousselin, Emmanuelle

“…Though these cases break our view of aphids harbouring a single obligate endosymbiont, we know little about the extent, nature, and evolution of these associations across aphid subfamilies. Here, using metagenomics on 25 aphid species from nine subfamilies, re-assembly and re-annotation of 20 aphid symbionts previously sequenced, and 16S rRNA amplicon sequencing on 223 aphid samples (147 species from 12 subfamilies), we show that dual symbioses have evolved anew at least six times. …”

Novel treatment strategy targeting interleukin-6 induced by cancer associated fibroblasts for peritoneal metastasis of gastric cancer by Ema Mitsui, Satoru Kikuchi, Tomohiro Okura, Hiroshi Tazawa, Yuta Une, Noriyuki Nishiwaki, Shinji Kuroda, Kazuhiro Noma, Shunsuke Kagawa, Toshiaki Ohara, Junko Ohtsuka, Rieko Ohki, Toshiyoshi Fujiwara

“…Abstract Cancer-associated fibroblasts (CAFs) are a crucial component in the tumor microenvironment (TME) of peritoneal metastasis (PM), where they contribute to tumor progression and metastasis via secretion of interleukin-6 (IL-6). Here, we investigated the role of IL-6 in PM of gastric cancer (GC) and assessed whether anti-IL-6 receptor antibody (anti-IL-6R Ab) could inhibit PM of GC. …”

Cell Morphology on Poly(methyl methacrylate) Microstructures as Function of Surface Energy by Matthias Katschnig, Boris Maroh, Natascha Andraschek, Sandra Schlögl, Ulrike Zefferer, Elisabeth Bock, Gerd Leitinger, Christa Trattnig, Maria Kaufmann, Werner Balika, Clemens Holzer, Ute Schäfer, Silke Patz

“…Whilst the significance of substrate topography as a regulator of cell function is well established, a systematic analysis of the principles underlying this is still unavailable. Here we evaluate the hypothesis that surface energy plays a decisive role in substrate-mediated modulation of cell phenotype by evaluation of cell behaviour on synthetic microstructures exhibiting pronounced differences in surface energy. …”

Internal climate variability modulates decadal changes in ocean anthropogenic carbon storage by Holly C Olivarez, Nicole S Lovenduski, Elizabeth Maroon, Jens D Müller, Amanda R Fay, Kristen M Krumhardt, Michael N Levy, Keith Lindsay, Galen A McKinley, Jamin K Rader

“…Observations from global hydrographic surveys reveal the spatial and temporal evolution of the ocean inventory of anthropogenic carbon and suggest substantial decadal variability in historical storage rates. Here, we use a 100-member ensemble of an Earth system model to investigate the influence of external forcing and internal climate variability on historical changes in ocean anthropogenic carbon storage over 1994 to 2014. …”
