An animal without a mitochondrial genome: the salmon parasite Henneguya salminicola (Cnidaria: Myxozoa)

Dorothée Huchon, Dayana Yahalomi, Stephen D. Atkinson, Moran Neuhof, E. Sally Chang, Hervé Philippe, Paulyn Cartwright & Jerri L. Bartholomew
Although aerobic respiration is a hallmark of eukaryotes, a few unicellular lineages, growing in hypoxic environments, have secondarily lost this ability. In the absence of oxygen, the mitochondria of these organisms have lost all or parts of their genomes and evolved into mitochondria related organelles (MROs). There has been debate regarding the presence of MROs in animals. Using deep sequencing approaches, we discovered that a member of the Cnidaria, the myxozoan Henneguya salminicola, has no...

Time course and diagnostic utility of NfL, tau, GFAp, and UCH-L1 in subacute and chronic TBI

Pashtun Shahim, Adam Politis, Andre Van Der Merwe, Brian Moore, Vindhya Ekanayake, Sara Lippa, Yi-Yu Chou, Dzung Pham, John Butman, Ramon Diaz-Arrastia, Henrik Zetterberg, Kaj Blennow, Jessica Gill, David Brody & Leighton Chan
Objective: To determine whether neurofilament light (NfL), glial fibrillary acidic protein (GFAP), tau, and ubiquitin C-terminal hydrolase-L1 (UCH-L1) measured in serum relate to traumatic brain injury (TBI) diagnosis, injury severity, brain volume, and diffusion tensor imaging (DTI) measures of traumatic axonal injury (TAI) in patients with TBI. Methods: Patients with TBI (n = 162) and controls (n = 68) were prospectively enrolled between 2011 and 2019. Patients with TBI also underwent serum, functional outcome, and...

Data from: Multiple sequence alignment averaging improves phylogeny reconstruction

Haim Ashkenazy, Itamar Sela, Eli Levy Karin, Giddy Landan & Tal Pupko
The classic methodology of inferring a phylogenetic tree from sequence data is composed of two steps. First, a multiple sequence alignment (MSA) is computed. Then, a tree is reconstructed assuming the MSA is correct. Yet, inferred MSAs were shown to be inaccurate and alignment errors reduce tree inference accuracy. It was previously proposed that filtering unreliable alignment regions can increase the accuracy of tree inference. However, it was also demonstrated that the benefit of this...

Data from: Revised Airlie House consensus guidelines for design and implementation of ALS clinical trials

Leonard H Van Den Berg, Eric Sorenson, Gary Gronseth, Eric A. Macklin, Jinsy Andrews, Robert H. Baloh, Michael Benatar, James D. Berry, Adriano Chio, Philippe Corcia, Angela Genge, Amelie K. Gubitz, Catherine Lomen-Hoerth, Christopher J. McDermott, Erik P. Pioro, Jeffrey Rosenfeld, Vincenzo Silani, Martin R. Turner, Markus Weber, Benjamin Rix Brooks, Robert G. Miller & Hiroshi Mitsumoto
Objective: To revise the 1999 Airlie House consensus guidelines for the design and implementation of preclinical therapeutic studies and clinical trials in amyotrophic lateral sclerosis (ALS). Methods: A consensus committee comprising 140 key members of the international ALS community (ALS researchers, clinicians, patient representatives, research funding representatives, industry and regulatory agencies) addressed nine areas of need within ALS research: 1. Pre-clinical studies; 2. Biological and phenotypic heterogeneity; 3. Outcome measures; 4. Disease-modifying and symptomatic interventions;...

Data from: High-throughput synapse-resolving two-photon fluorescence microendoscopy for deep-brain volumetric imaging in vivo

Guanghan Meng, Yajie Liang, Sarah Sarsfield, Wan-Chen Jiang, Rongwen Lu, Joshua Tate Dudman, Yeka Aponte & Na Ji
Optical imaging has become a powerful tool for studying brains in vivo. The opacity of adult brains makes microendoscopy, with an optical probe such as a gradient index (GRIN) lens embedded into brain tissue to provide optical relay, the method of choice for imaging neurons and neural activity in deeply buried brain structures. Incorporating a Bessel focus scanning module into two-photon fluorescence microendoscopy, we extended the excitation focus axially and improved its lateral resolution. Scanning...

Blocking core fucosylation of epidermal growth factor (EGF) receptor prevents peritoneal fibrosis progression

Changqing Yu, Ning Yang, Weidong Wang, Xiangning Du, Qingzhu Tang, Hongli Lin & Longkai Li
Peritoneal fibrosis (PF) ultimately causes ultrafiltration failure and peritoneal dialysis (PD) termination, but there are few effective therapies for it. Core fucosylation, which is catalyzed by α1,6-fucosyltransferase (Fut8) in mammals, may play a crucial role in PF development. This study aims to assess the effects of inhibiting core fucosylation of epidermal growth factor (EGF) receptor on PF rats. PF rats (established by 4.25% glucose dialysate) were treated with either an adenovirus-Fut8 short hairpin RNA (Fut8shRNA)...

Epigenome-wide association studies of occupational exposure to benzene and formaldehyde

Rachael V. Phillips, Linqing Wei, Andres Cardenas, Alan E. Hubbard, Cliona M. McHale, Roel Vermeulen, Hu Wei, Martyn T. Smith, Luoping Zhang, Qing Lan & Nathaniel Rothman
Sufficient evidence supports a relationship between certain myeloid neoplasms and exposure to benzene or formaldehyde. DNA methylation could underlie benzene- and formaldehyde-induced health outcomes, but data in exposed human populations are limited. We conducted two cross-sectional epigenome-wide association studies (EWAS), one in workers exposed to benzene and another in workers exposed to formaldehyde. Using HumanMethylation450 BeadChips, we investigated differences in blood cell DNA methylation among 50 benzene-exposed subjects and 48 controls, and among 31 formaldehyde-exposed...

Elevated Ras related GTP binding B (RRAGB) expression predicts poor overall survival and constructs a prognostic nomogram for colon adenocarcinoma

Jianjia Xiao, Qingqing Liu, Weijie Wu, Ying Yuan, Jie Zhou, Jieyu Shi & Shaorong Zhou
Currently, no articles have explored the roles of RRAGB gene in the occurrence and development of cancer. By means of The Cancer Genome Atlas (TCGA) data mining, we found that this gene might be a novel prognostic predictor for colon adenocarcinoma (COAD). Hence, this article was carried out to explore its roles in COAD and associations with immunity. RRAGB single-gene expression matrix and corresponding clinical information were extracted from TCGA database. Univariate/multivariate cox regression analyses...

Data from: A new versatile primer set targeting a short fragment of the mitochondrial COI region for metabarcoding metazoan diversity: application for characterizing coral reef fish gut contents

Matthieu Leray, Joy Y. Yang, Christopher P. Meyer, Suzanne C. Mills, Natalia Agudelo, Ranwez Vincent, Joel T. Boehm & Ryuji J. Machida
Introduction: The PCR-based analysis of homologous genes has become one of the most powerful approaches for species detection and identification, particularly with the recent availability of Next Generation Sequencing platforms (NGS) making it possible to identify species composition from a broad range of environmental samples. Identifying species from these samples relies on the ability to match sequences with reference barcodes for taxonomic identification. Unfortunately, most studies of environmental samples have targeted ribosomal markers, despite the...

Data from: Maternal effects and population regulation: maternal density-induced reproduction suppression impairs offspring capacity in response to immediate environment in root voles Microtus oeconomus

Jiang-Hui Bian, Shou-Yang Du, Yan Wu, Yi-Fan Cao, Xu-Heng Nie, Hui He & Zhi-Bing You
1. The hypothesis that maternal effects act as an adaptive bridge in translating maternal environments into offspring phenotypes and thereby affecting population dynamics has not been studied in the well-controlled fields. 2. In this study, the effects of maternal population-density on offspring stress axis, reproduction and population dynamics were studied in root voles (Microtus oeconomus). Parental enclosures for breeding offspring were established by introducing 6 adults per sex into each of 4 (low density) and...

Data from: Quantifying hummingbird preference for floral trait combinations: the role of selection on trait interactions in the evolution of pollination syndromes

Charles B. Fenster, Richard J. Reynolds, Christopher W. Williams, Robert Makowsky & Michele R. Dudash
Darwin recognized the flower's importance for the study of adaptation and emphasized that the flower's functionality reflects the coordinated action of multiple traits. Here we use a multi-trait manipulative approach to quantify the potential role of selection acting on floral trait combinations underlying the divergence and maintenance of three related North American species of Silene (Caryophyllaceae). We artificially generated 48 plant phenotypes corresponding to all combinations of key attractive traits differing among the three Silene...

Data from: Integrating influenza antigenic dynamics with molecular evolution

Trevor Bedford, Marc A. Suchard, Philippe Lemey, Gytis Dudas, Victoria Gregory, Alan J. Hay, John W. McCauley, Colin A. Russell, Derek J. Smith & Andrew Rambaut
Influenza viruses undergo continual antigenic evolution allowing mutant viruses to evade host immunity acquired to previous virus strains. Antigenic phenotype is often assessed through pairwise measurement of cross-reactivity between influenza strains using the hemagglutination inhibition (HI) assay. Here, we extend previous approaches to antigenic cartography, and simultaneously characterize antigenic and genetic evolution by modeling the diffusion of antigenic phenotype over a shared virus phylogeny. Using HI data from influenza lineages A/H3N2, A/H1N1, B/Victoria and B/Yamagata,...

Data from: Existing infection facilitates establishment and density of malaria parasites in their mosquito vector

Laura C. Pollitt, Joshua T. Bram, Simon Blanford, Matthew J. Jones & Andrew F. Read
Very little is known about how vector-borne pathogens interact within their vector and how this impacts transmission. Here we show that mosquitoes can accumulate mixed strain malaria infections after feeding on multiple hosts. We found that parasites have a greater chance of establishing and reach higher densities if another strain is already present in a mosquito. Mixed infections contained more parasites but these larger populations did not have a detectable impact on vector survival. Together...

Data from: Imperfect vaccination can enhance the transmission of highly virulent pathogens

Andrew F. Read, Susan J. Baigent, Claire Powers, Lydia B. Kgosana, Luke Blackwell, Lorraine P. Smith, David A. Kennedy, Stephen W. Walkden-Brown & Venugopal K. Nair
Could some vaccines drive the evolution of more virulent pathogens? Conventional wisdom is that natural selection will remove highly lethal pathogens if host death greatly reduces transmission. Vaccines that keep hosts alive but still allow transmission could thus allow very virulent strains to circulate in a population. Here we show experimentally that immunization of chickens against Marek's disease virus enhances the fitness of more virulent strains, making it possible for hyperpathogenic strains to transmit. Immunity...

Data from: Distributed acoustic cues for caller identity in macaque vocalization

Makoto Fukushima, Alexandra M. Doyle, Matthew P. Mullarkey, Mortimer Mishkin, Bruno B. Averbeck & Alex M. Doyle
Individual primates can be identified by the sound of their voice. Macaques have demonstrated an ability to discern conspecific identity from a harmonically structured ‘coo’ call. Voice recognition presumably requires the integrated perception of multiple acoustic features. However, it is unclear how this is achieved, given considerable variability across utterances. Specifically, the extent to which information about caller identity is distributed across multiple features remains elusive. We examined these issues by recording and analysing a...

Data from: Genome sequencing highlights the dynamic early history of dogs

Adam H. Freedman, Ilan Gronau, Rena M. Schweizer, Diego Ortega-Del Vecchyo, Eunjung Han, Pedro M. Silva, Marco Galaverni, Zhenxin Fan, Peter Marx, Belen Lorente-Galdos, Holly Beale, Oscar Ramirez, Farhad Hormozdiari, Can Alkan, Carles Vilà, Kevin Squire, Eli Geffen, Josip Kusak, Adam R. Boyko, Heidi G. Parker, Clarence Lee, Vasisht Tadigotla, Adam Siepel, Carlos D. Bustamante, Timothy T. Harkins … & John Novembre
To identify genetic changes underlying dog domestication and reconstruct their early evolutionary history, we generated high-quality genome sequences from three gray wolves, one from each of the three putative centers of dog domestication, two basal dog lineages (Basenji and Dingo) and a golden jackal as an outgroup. Analysis of these sequences supports a demographic model in which dogs and wolves diverged through a dynamic process involving population bottlenecks in both lineages and post-divergence gene flow....

Data from: Genome-wide evolutionary dynamics of influenza B viruses on a global scale

Pinky Langat, Jayna Raghwani, Gytis Dudas, Thomas A. Bowden, Stephanie Edwards, Astrid Gall, Trevor Bedford, Andrew Rambaut, Rodney S. Daniels, Colin A. Russell, Oliver G. Pybus, John McCauley, Paul Kellam & Simon J. Watson
The global-scale epidemiology and genome-wide evolutionary dynamics of influenza B remain poorly understood compared with influenza A viruses. We compiled a spatio-temporally comprehensive dataset of influenza B viruses, comprising over 2,500 genomes sampled worldwide between 1987 and 2015, including 382 newly-sequenced genomes that fill substantial gaps in previous molecular surveillance studies. Our contributed data increase the number of available influenza B virus genomes in Europe, Africa and Central Asia, improving the global context to study...

Data from: The E3 ubiquitin ligase MARCH1 regulates glucose-tolerance and lipid storage in a sex-specific manner

Candida Bhagwandin, Erin L. Ashbeck, Michael Whalen, Joanna Bandola-Simon, Paul A. Roche, Adam Szajman, Sarah Mai Truong, Betsy C. Wertheim, Yann C. Klimentidis, Satoshi Ishido, Benjamin J. Renquist & Lonnie Lybarger
Type 2 diabetes is typified by insulin-resistance in adipose tissue, skeletal muscle, and liver, leading to chronic hyperglycemia. Additionally, obesity and type 2 diabetes are characterized by chronic low-grade inflammation. Membrane-associated RING-CH-1 (MARCH1) is an E3 ubiquitin ligase best known for suppression of antigen presentation by dendritic and B cells. MARCH1 was recently found to negatively regulate the cell surface levels of the insulin receptor via ubiquitination. This, in turn, impaired insulin sensitivity in mouse...

Objective: To determine whether serum neurofilament light (NfL) correlates with CSF NfL, traumatic brain injury (TBI) diagnosis, injury severity, brain volume, and diffusion tensor imaging (DTI) estimates of traumatic axonal injury (TAI). Methods: Participants were prospectively enrolled in Sweden and the United States between 2011 and 2019. The Swedish cohort included 45 hockey players with acute concussion sampled at 6 days, 31 with repetitive concussion with persistent postconcussive symptoms (PCS) assessed with paired CSF and...

Data from: Marking mosquitoes in their natural larval sites using 2H-enriched water: a promising approach for tracking over extended temporal and spatial scales

Roy Faiman, Adama Dao, Alpha Yaro, Moussa Diallo, Samake Djibril, Zana L. Sonogo, Yossi Ousmane, Margerie Sullivan, Laura Veru, Benjamin Krajacich, Asha Krishna, Joy Matthews, Christine France, Gabriel Hamer, Keith Hobson & Tovi Lehmann
1. Background. Tracking mosquitoes using current methods of mark-release-recapture are limited to small spatial and temporal scales exposing major gaps in understanding long-range movements and extended survival. Novel approaches to track mosquitoes may yield fresh insights into their biology which improves intervention activities to reduce disease transmission. Stable isotope enrichment of natural mosquito breeding sites allows large-scale marking of wild mosquitoes absent human handling. Mosquito larvae that develop in 2H-enriched water are expected to be...
