LINE-1 retrotransposons contribute to mouse PV interneuron development

Retrotransposons are mobile DNA sequences duplicated via transcription and reverse transcription of an RNA intermediate. Cis-regulatory elements encoded by retrotransposons can also promote the transcription of adjacent genes. Somatic LINE-1 (L1) retrotransposon insertions have been detected in mammalian neurons. It is, however, unclear whether L1 sequences are mobile in only some neuronal lineage

L1 retrotransposition is a common feature of mammalian hepatocarcinogenesis

The retrotransposon Long Interspersed Element 1 (LINE-1 or L1) is a continuing source of germline and somatic mutagenesis in mammals. Deregulated L1 activity is a hallmark of cancer, and L1 mutagenesis has been described in numerous human malignancies. We previously employed retrotransposon capture sequencing (RC-seq) to analyze hepatocellular carcinoma (HCC) samples from patients infected with he

Unraveling the Genetics of Shared Clinical and Serological Manifestations in Patients With Systemic Inflammatory Autoimmune Diseases

OBJECTIVE: Systemic inflammatory autoimmune diseases (SIADs) such as systemic lupus erythematosus (SLE), primary Sjögren disease (pSS), and idiopathic inflammatory myopathies (myositis) are complex conditions characterized by shared circulating autoantibodies and clinical manifestations, including skin rashes, among others. This study was aimed at elucidating the genetics underlying these common f

ANKRD55 and DHCR7 are novel multiple sclerosis risk loci

Multiple sclerosis (MS) shares some risk genes with other disorders hallmarked by an autoimmune pathogenesis, most notably IL2RA and CLEC16A. We analyzed 10 single-nucleotide polymorphisms (SNPs) in nine risk genes, which recently emerged from a series of non-MS genome-wide association studies (GWAS), in a Spanish cohort comprising 2895 MS patients and 2942 controls. We identified two SNPs associa

The protective gene dose effect of the APOE ε2 allele on gray matter volume in cognitively unimpaired individuals

Introduction: Harboring two copies of the apolipoprotein E (APOE) ε2 allele strongly protects against Alzheimer's disease (AD). However, the effect of this genotype on gray matter (GM) volume in cognitively unimpaired individuals has not yet been described. Methods: Multicenter brain magnetic resonance images (MRIs) from cognitively unimpaired ε2 homozygotes were matched (1:1) against all other AP

COG8 deficiency causes new congenital disorder of glycosylation type IIh

We describe a new Type II congenital disorder of glycosylation (CDG-II) caused by mutations in the conserved oligomeric Golgi (COG) complex gene, COG8. The patient has severe psychomotor retardation, seizures, failure to thrive and intolerance to wheat and dairy products. Analysis of serum transferrin and total serum N-glycans showed normal addition of one sialic acid, but severe deficiency in sub

Systems biology analysis of human genomes points to key pathways conferring spina bifida risk

Spina bifida (SB) is a debilitating birth defect caused by multiple gene and environment interactions. Though SB shows non-Mendelian inheritance, genetic factors contribute to an estimated 70% of cases. Nevertheless, identifying human mutations conferring SB risk is challenging due to its relative rarity, genetic heterogeneity, incomplete penetrance, and environmental influences that hamper genome

Hexavalent chromium still a concern in Sweden - Evidence from a cross-sectional study within the SafeChrom project

OBJECTIVES: Hexavalent chromium (Cr(VI)) is classified as a human carcinogen. Occupational Cr(VI) exposure can occur during different work processes, but the current exposure to Cr(VI) at Swedish workplaces is unknown.METHODS: This cross-sectional study (SafeChrom) recruited non-smoking men and women from 14 companies with potential Cr(VI) exposure (n = 113) and controls from 6 companies without C

From Great Novels to Jantsch/Prigogine, Ken Wilber and Stephen Wolfram. Erland Lageroth's Homepage

"Search is our greatest adventure" (Rolf Edberg). Join me in this adventure and experience the same joy, enlightment, and insight that this journey of discoveries during 50 years has given me! The journey, way, narrative begins with criticism of fiction and goes via rethinking of literary research, humanities, and natural science to the discovery of a "humanistic" natural science, a "world philos

Association of Lipid-Related Genetic Variants with the Incidence of Atrial Fibrillation : The AFGen Consortium

BACKGROUND: Several studies have shown associations between blood lipid levels and the risk of atrial fibrillation (AF). To test the potential effect of blood lipids with AF risk, we assessed whether previously developed lipid gene scores, used as instrumental variables, are associated with the incidence of AF in 7 large cohorts.METHODS: We analyzed 64,901 individuals of European ancestry without

Diagnosis and management of dementia with Lewy bodies - Third report of the DLB consortium

The dementia with Lewy bodies (DLB) Consortium has revised criteria for the clinical and pathologic diagnosis of DLB incorporating new information about the core clinical features and suggesting improved methods to assess them. REM sleep behavior disorder, severe neuroleptic sensitivity, and reduced striatal dopamine transporter activity on functional neuroimaging are given greater diagnostic weig

Oxidative stress and life histories: unresolved issues and current needs.

Life-history theory concerns the trade-offs that mold the patterns of investment by animals between reproduction, growth, and survival. It is widely recognized that physiology plays a role in the mediation of life-history trade-offs, but the details remain obscure. As life-history theory concerns aspects of investment in the soma that influence survival, understanding the physiological basis of li

CONSORT-Children and Adolescents (CONSORT-C) 2026 Extension Statement : Enhancing the Reporting and Impact of Pediatric Randomized Trials

IMPORTANCE: Randomized controlled trials (RCTs) in children and adolescents provide evidence for patients, families, researchers, clinicians, regulators, funders, policymakers, and other interest holders to inform decisions about health care interventions and improve outcomes for young patients and their families. To critically evaluate, interpret, and apply trial results, readers require access t

SPIRIT-Children and Adolescents (SPIRIT-C) 2026 Extension Statement : Enhancing the Reporting and Usefulness of Pediatric Randomized Trial Protocols

IMPORTANCE: Key information is often omitted from pediatric randomized controlled trial (RCT) protocols, including details on dose adjustments of interventions based on age, body surface area, or weight; developmental appropriateness of trial outcome measures and processes; or strategies to minimize participants' anxiety and pain. These deficiencies impair the planning and implementation of potent

Production of hyperpolarized [1,4-13C2]malate from [1,4-13C2]fumarate is a marker of cell necrosis and treatment response in tumors

Dynamic nuclear polarization of (13)C-labeled cell substrates has been shown to massively increase their sensitivity to detection in NMR experiments. The sensitivity gain is sufficiently large that if these polarized molecules are injected intravenously, their spatial distribution and subsequent conversion into other cell metabolites can be imaged. We have used this method to image the conversion

Dissemination and implementation of injury prevention interventions : a scoping review for the Female, woman and girl Athlete Injury pRevention (FAIR) consensus

OBJECTIVE: To synthesise evidence related to the dissemination and implementation (D&I) of injury prevention interventions for female, woman and/or girl (female/woman/girl) athletes.DESIGN: Scoping review.DATA SOURCES: MEDLINE, APA PsycInfo, Cochrane Databases for Systematic Review, Cochrane Central Register for Controlled Trials Registry, EMBASE, CINAHL, SPORTDiscus, ERIC, ProQuest Dissertati

The Genomic and Epigenomic Landscape of Double-Negative Metastatic Prostate Cancer

UNLABELLED: Systemic targeted therapy in prostate cancer is primarily focused on ablating androgen signaling. Androgen deprivation therapy and second-generation androgen receptor (AR)-targeted therapy selectively favor the development of treatment-resistant subtypes of metastatic castration-resistant prostate cancer (mCRPC), defined by AR and neuroendocrine (NE) markers. Molecular drivers of doubl
