Insulin Resistance in the 21st Century: New Takes on an Old Problem—2025 Diabetes , Diabetes Care , and Diabetologia Expert Forum

Insulin resistance is a hallmark of type 2 diabetes and several other metabolic diseases. However, efforts to improve insulin resistance are hindered by the biological complexity inherent to insulin action, as well as conceptual and methodological limitations to date. In Septembe...

An integrated spatially defined roadmap of normal and cancer-associated colon fibroblasts

Abstract Cancer-associated fibroblasts (CAFs) promote tumorigenesis and represent potential therapeutic targets, highlighting the need for precise understanding of CAF heterogeneity. In colorectal cancer (CRC), CAF subsets and nomenclature vary widely, and many studies overlook t...

Genome-wide analysis of social behaviour across social domains, reporters and developmental stages: a meta-regression approach

Abstract Social behaviour is a heritable trait linked to well-being and mental health, yet it varies across social context, including social domains, informants and development, which may shape its underlying genomic architecture. Here, we conducted a genome-wide meta-regression...

A genetic and historical perspective on the origins of keratitis fugax hereditaria

Abstract Purpose To investigate the genetic and genealogical background of keratitis fugax hereditaria (KFH), a periodic corneal disease caused by the heterozygous pathogenic variant c.61G>C in the NLRP3 gene. KFH is characterized by recurrent unilateral autoinflammatory attacks...

Craniofacial growth in Mulibrey nanism and impact of growth hormone treatment

Abstract Background Mulibrey nanism (MUL) impacts cellular metabolism and leads to severe prenatal onset growth restriction, distinctive craniofacial features, heart disease, hypogonadism, and predisposition to tumors. Growth hormone therapy is commonly used in treatment of patie...

Robust inference and correlates from genetic associations with personality

Personality traits describe stable differences in how people think, feel and behave, and how they interact with and experience their social and physical environments1,2. Many questions remain unanswered about associations between DNA and personality traits, such as their robustne...

Multi-modal learning with incomplete data

Multi-modal learning, in which diverse data types are integrated and analyzed together, has become a central area of research in artificial intelligence, driving major advances in a wide range of domains. However, in many practical situations, certain modalities or variables may...

Joint-RPCA: domain-aware multi-omics integration for systems microbiology

Integrating multi-omics data is essential for microbiome research, as microbial communities are shaped by and respond to interdependent processes, including taxonomic composition, metabolite production and utilization, and gene expression. However, accurately capturing ecosystem-...

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures

We developed a high-content screening to investigate how Alzheimer’s disease (AD) genetic risk factors may affect synaptic mechanisms in rat primary neuronal cultures. Of the target genes identified, we found that Plcg2 downregulation in mouse dentate gyrus neurons consistently d...
