Filip Mundt, Gustav Nilsonne, Sertaç Arslan, Karola Csürös, Gunnar Hillerdal, Huseyin Yildirim, Muzaffer Metintas, Katalin Dobra & Anders Hjerpe
Purpose: Diagnosis of malignant mesothelioma is challenging. The first available diagnostic material is often an effusion and biochemical analysis of soluble markers may provide additional diagnostic information. This study aimed to establish a predictive model using biomarkers from pleural effusions, to allow early and accurate diagnosis. Patients and Methods: Effusions were collected prospectively from 190 consecutive patients at a regional referral centre. Hyaluronan, N-ERC/mesothelin, C-ERC/mesothelin, osteopontin, syndecan-1, syndecan-2, and thioredoxin were measured using ELISA and...

Data from: Combined structural, biochemical and cellular evidence demonstrates that both FGDF motifs in alphavirus nsP3 are required for efficient replication

Tim Schulte
Recent findings have highlighted the role of the Old World alphavirus non-structural protein 3 (nsP3) as a host defence modulator that functions by disrupting stress granules, subcellular phase-dense RNA/protein structures formed upon environmental stress. This disruption mechanism was largely explained through nsP3-mediated recruitment of the host G3BP protein via two tandem FGDF motifs. Here, we present the 1.9 Å resolution crystal structure of the NTF2-like domain of G3BP-1 in complex with a 25-residue peptide derived...

Data from: The effects of spatial structure, frequency dependence and resistance evolution on the dynamics of toxin-mediated microbial invasions

Ben Libberton, Malcolm J. Horsburgh & Michael A. Brockhurst
Recent evidence suggests that interference competition between bacteria shapes the distribution of the opportunistic pathogen Staphylococcus aureus in the lower nasal airway of humans, either by preventing colonization or by driving displacement. This competition within the nasal microbial community would add to known host factors that affect colonization. We tested the role of toxin-mediated interference competition in both structured and unstructured environments, by culturing S. aureus with toxin-producing or nonproducing Staphylococcus epidermidis nasal isolates. Toxin-producing...

Data from: Mutations in COL1A1 and COL1A2 and dental aberrations in children and adolescents with osteogenesis imperfecta - a retrospective cohort study

Kristofer Andersson, Göran Dahllöf, Katarina Lindahl, Andreas Kindmark, Giedre Grigelioniene, Eva Åström & Barbro Malmgren
Osteogenesis imperfecta (OI) is a heterogeneous group of disorders of connective tissue, caused mainly by mutations in the collagen I genes (COL1A1 and COL1A2). Dentinogenesis imperfecta (DGI) and other dental aberrations are common features of OI. We investigated the association between collagen I mutations and DGI, taurodontism, and retention of permanent second molars in a retrospective cohort of 152 unrelated children and adolescents with OI. The clinical examination included radiographic evaluations. Teeth from 81 individuals...

Data from: Increased dopamine release after working-memory updating training: neurochemical correlates of transfer

Lars Bäckman, Otto Waris, Jarkko Johansson, Micael Andersson, Juha O. Rinne, Kati Alakurtti, Anna Soveri, Matti Laine & Lars Nyberg
Previous work demonstrates that working-memory (WM) updating training results in improved performance on a letter-memory criterion task, transfers to an untrained n-back task, and increases striatal dopamine (DA) activity during the criterion task. Here, we sought to replicate and extend these findings by also examining neurochemical correlates of transfer. Four positron emission tomography (PET) scans using the radioligand raclopride were performed. Two of these assessed DAD2 binding (letter memory; n-back) before 5 weeks of updating...

Data from: Parallel telomere shortening in multiple body tissues owing to malaria infection

Muhammad Asghar, Vaidas Palinauskas, Nadège Zaghdoudi-Allan, Gediminas Valkiūnas, Andrey Mukhin, Elena Platonova, Anna Färnert, Staffan Bensch & Dennis Hasselquist
Several studies have shown associations between shorter telomere length in blood and weakened immune function, susceptibility to infections, and increased risk of morbidity and mortality. Recently, we have shown that malaria accelerates telomere attrition in blood cells and shortens lifespan in birds. However, the impact of infections on telomere attrition in different body tissues within an individual is unknown. Here, we tested whether malarial infection leads to parallel telomere shortening in blood and tissue samples...

Sleep disturbance and intrusive memories after presenting to the emergency department following a traumatic motor vehicle accident: an exploratory analysis

Annemarie I. Luik, Lalitha Iyadurai, Isabel Gebhardt & Emily A. Holmes
Background: Sleep disturbances are common after traumatic events and have been hypothesized to be a risk factor in the development of psychopathology such as that associated with posttraumatic stress disorder (PTSD). Objective: To assess the association between intrusive memories, a core clinical feature of PTSD, and self-reported sleep disturbance shortly after experiencing or witnessing a motor vehicle accident, and whether a brief behavioural intervention (trauma reminder cue and Tetris gameplay) reduced sleep disturbance post-trauma. Method:...

Landscape of RNA editing reveals new insights into the dynamic gene regulation of spermatogenesis

Xiaodan Wang, Xiaolong Wu, Zhenshuo Zhu, Hao Li, Tongtong Li, Qun Li, Peng Zhang, Leijie Li, Dongxue Che, Xia Xiao, Tong Liu, Jinlian Hua & Mingzhi Liao
Spermatogenesis is an important physiological process associated with male infertility. As a kind of post-transcriptional regulation, RNA editings (REs) change the genetic information at the mRNA level. But whether there are REs and what’s the role of REs during the process are still unclear. In this study, we integrated published RNA-Seq datasets and established a landscape of RNA REs during the development of mouse spermatogenesis. Totally, 7530 editing sites occurred in 2012 genes among all...

Yuchang Li, Jing Li, Ying Zhang, Lizhong Dai, Lin Li, Juan Liu, Sen Zhang, Xiaoyan Wu, Yi Hu, Chenfeng Qin, Tao Jiang & Xiaoping Kang
In December 2019, Wuhan, China suffered a serious outbreak of a novel coronavirus infectious disease (COVID) caused by novel severe acute respiratory syndrome-related coronavirus (SARS-CoV 2). To quickly identify the pathogen, we designed and screened primer sets, and established a sensitive and specific qRT-PCR assay for SARS-CoV 2; the lower limit of detection (LOD) was 14.8 (95% CI: 9.8–21) copies per reaction. We combined this qRT-PCR assay with an automatic integration system for nucleic acid...

How severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections engage cellular host pathways and innate immunity in infected cells remains largely elusive. We performed an integrative proteo-transcriptomics analysis in SARS-CoV-2 infected Huh7 cells to map the cellular response to the invading virus over time. We identified four pathways, ErbB, HIF-1, mTOR and TNF signaling, among others that were markedly modulated during the course of the SARS-CoV-2 infection in vitro. Western blot validation of the downstream effector...

Mice deficient in UXT exhibit retinitis pigmentosa-like features via aberrant autophagy activation

Mingyu Pan, Yue Yin, Xinxia Wang, Quanyi Wang, Lele Zhang, Haiyang Hu & Chen Wang
UXT (ubiquitously expressed prefoldin like chaperone), a small chaperone-like protein, is widely expressed in diverse human and mouse tissues and is more abundant in retina and kidney. However, the functional characterization of UXT at tissue level was largely unknown. Here, we reported that mice deficient in UXT exhibited salient features of retinal degenerative disease, similar to retinitis pigmentosa. Conditional knockout (CKO) of Uxt led to retinal degeneration and pigmentation in mice retina along with significant...

Elisabet Stener-Victorin, Sanjiv Risal, Maria Manti, Haojiang Lu, Romina Fornes, Henrik Larsson, Anna Benrick, Qiaolin Deng, Mina A. Rosenqvist & Carolyn E. Cesta
If and how obesity and elevated androgens in women with polycystic ovary syndrome (PCOS) affect their offspring’s psychiatric health is unclear. Using data from Swedish population health registers, we showed that daughters of mothers with PCOS have a 78% increased risk of being diagnosed with anxiety disorders. We next generated a PCOS-like mouse (F0) model induced by androgen exposure during late gestation, with or without diet-induced maternal obesity, and showed that the first generation (F1)...

Data from: Quantification of endogenous and exogenous protein expressions of Na,K-ATPase with super-resolution PALM/STORM imaging

Kristoffer Bernhem, Hans Blom & Hjalmar Brismar
Transient transfection of fluorescent fusion proteins is a key enabling technology in fluorescent microscopy to spatio-temporally map cellular protein distributions. Transient transfection of proteins may however bypass normal regulation of expression, leading to overexpression artefacts like misallocations and excess amounts. In this study we investigate the use of STORM and PALM microscopy to quantitatively monitor endogenous and exogenous protein expression. Through incorporation of an N-terminal hemagglutinin epitope to a mMaple3 fused Na,K-ATPase (α1 isoform), we...

Data from: Reproductive and behavior dysfunction induced by maternal androgen exposure and obesity is likely not gut microbiome-mediated

Lisa Lindheim, Maria Manti, Romina Fornes, Mina Bashir, Paulo Czarnewski, Oscar E Diaz, Maike Seifert, Lars Engstrand, Eduardo J Villablanca, Barbara Obermayer-Pietsch & Elisabet Stener-Victorin
Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder of unclear etiology in women and is characterized by androgen excess, insulin resistance, and mood disorders. The gut microbiome is known to influence conditions closely related with PCOS, and several recent studies have observed changes in the stool microbiome of women with PCOS. The mechanism by which the gut microbiome interacts with PCOS is still unknown. We used a mouse model to investigate if...

The sepsis patient cohort has heterogeneous etiologies and location of infection. Additionally, we included a group of patients that...

N6-methyladenosine RNA modification and its interaction with regulatory non-coding RNAs in colorectal cancer

Yiling Ge, Tong Liu, Chuntao Wang, Yanqiu Zhang, Siyi Xu, Yiyi Ren, Yanlu Feng, Lihong Yin, Yuepu Pu & Geyu Liang
As one of the most common forms of RNA modification, N6-methyladenosine (m6A) RNA modification has attracted increasing research interest in recent years. This reversible RNA modification added a new dimension to the post-transcriptional regulation of gene expression. In colorectal cancer (CRC), the role of m6A modification has been extensively studied, not only on mRNAs but also on non-coding RNAs (ncRNAs). In the present review, we depicted the role of m6A modification in CRC, systematically elaborate...

Role of intestinal extracellular matrix-related signaling in porcine epidemic diarrhea virus infection

Yuchen Li, Jianda Li, Xiuyu Wang, Qingxin Wu & Qian Yang
Porcine epidemic diarrhea virus (PEDV) is emerging as a major threat to the global swine industry. Clinical PEDV infection is associated with severe intestinal lesions, resulting in absorptive dysfunction and high mortality rates in suckling piglets. The extracellular matrix (ECM) is an important component of intestinal tissue, providing a structural framework and conveying tissue-specific signals to nearby enterocytes. In this study, we investigated the extensive ECM remodeling observed in intestinal epithelial cells infected with PEDV...

Abstract Background and aims Automated recording of laboratory animal’s home cage behavior is receiving increasing attention since such non-intruding surveillance will aid in the unbiased understanding of the normal animal cage behavior potentially improving animal experimental reproducibility. Material and methods Here we investigate activity of group held (5 mice/cage) female C57BL/6J mice (mus musculus) housed in standard Individually Ventilated Cages (IVC cages) across three test-sites: Consiglio Nazionale delle Ricerche (Rome, Italy), The Jackson Laboratory (Bar...

Small RNA expression and miRNA modification dynamics in human oocytes and early embryos

Pauliina Paloviita, Christel Hydén-Granskog, Juha S. Tapanainen, Timo Tuuri & Sanna Vuoristo
Small non-coding RNAs (sRNAs) play important roles during the oocyte-to-embryo transition (OET), when the maternal phenotype is reprogrammed, and the embryo genome is gradually activated. The transcriptional program driving early human development has been studied with the focus mainly on protein-coding RNAs, and expression dynamics of sRNAs remains largely unexplored. We profiled sRNAs in human oocytes and early embryos using an RNA-sequencing (RNA-seq) method suitable for low inputs of material. We show that OET in...

Simultaneous visualization of DNA loci in single cells by combinatorial multi-color iFISH

Magda Bienko
We describe a dataset obtained by applying our recently developed iFISH pipeline to simultaneously visualize 16 small (size range: 62–73 kilobases, kb) evenly spaced DNA loci on chromosome 2 in human cells, in a single round of hybridization. We show how, using combinatorial color coding, multiple loci can be precisely 3D localized in single cells, and how inter-loci distances scale inversely with chromosome contact frequencies determined by Hi-C, as expected. We provide raw images and...
