Genome-wide association studies (GWAS) have identified thousands of genetic variants associated with complex human traits, but only a fraction of variants identified in discovery studies achieve significance in replication studies. Replication in genome-wide association studies has been well-studied in the context of Winner's Curse, which is the inflation of effect size estimates for significant variants due to statistical chance. However, Winner's Curse is often not sufficient to explain lack of replication. Another reason why studies fail to replicate is that there are fundamental difference

Disruptions in gut microbiome are implicated in cardiometabolic disorders and other health outcomes. Antibiotics are known gut microbiome disruptors, but their long-term consequences remain underexplored. Here we combined individual-level data from the Swedish Prescribed Drug Register with fecal metagenomes of 14,979 adults to examine the association between oral antibiotic use over 8 years and gut microbiome. In multivariable confounder-adjusted regression models, antibiotic use <1 year before fecal sampling was associated with the greatest reduction in species diversity, but significant asso

Most dog owners in Western countries regard their dogs as companions or family members, prompting extensive research on the human-animal bond. However, many studies rely on broad categories or single dimensions, such as satisfaction or attachment, which can oversimplify the complexity of these relationships. In contrast, our study employed a multifaceted approach, examining the dog-owner bond across 13 relationship scales and comparing these scales to four different types of human relationships to reveal the human-like roles of dogs within a family.

BACKGROUND: The heart depends on a continuous and flexible energy supply from fatty acids, glucose, and other substrates. Emerging evidence shows that gut microbiota-derived metabolites-such as trimethylamine-N-oxide (TMAO), short-chain fatty acids (SCFAs), secondary bile acids, indoles, phenylacetylglutamine (PAGln), and branched-chain amino acids-modulate cardiac metabolism and function. Although clinical evidence linking these metabolites to cardiovascular outcomes is expanding, most data remain associative, with limited causal or interventional proof.

ABSTRACT Melanoma is the most aggressive skin malignant tumor, typically exhibiting a high mutation burden and potentially harboring mutations in NRAS, BRAF, or NF1. To enhance survival rates, these driver alterations can achieve significant antitumor activity through targeted therapy. In the past decade, BRAF inhibitors combined with MEK inhibitors significantly improved the prognosis of BRAF mutation melanoma. Nevertheless, researchers have attempted various strategies to block the NRAS signaling pathway, NRAS mutation in melanoma is still considered to be untargetable. In recent years, MEK

The origin of the universal asymmetry between matter and antimatter remains a mystery. Electroweak baryogenesis is a well-motivated mechanism for generating the asymmetry dynamically, using interesting features of the Standard Model. In addition, it relies on beyond-the-Standard Model physics active around the electroweak scale: new physics coupling to the Higgs to make the electroweak phase transition first order, and a new mechanism of CP violation. The relatively low energy scale at which electroweak baryogenesis occurs makes certain aspects of the mechanism testable through collider experi

Abstract Plague is among the most devastating diseases in human history 1 . However, early strains of the plague-causing bacterium Yersinia pestis lacked virulence factors that are required for the bubonic form until around 3,800 years ago 2,3 . Consequently, the morbidity and mortality of early plague strains remain unclear. Here we describe early plague strains that are associated with two phases of outbreaks among mid-Holocene hunter-gatherers near Lake Baikal in southeast Siberia, beginning from about 5,500 years ago. These outbreaks occur across four hunter-gatherer cemeteries, with a 39%

Curcumin is widely recognized for its anti-inflammatory and antioxidant properties; however, this conventional framing obscures a broader, complex, and mechanistically diverse pharmacology. Here, we advance a refined perspective that situates curcumin within a hierarchical and multilayered architecture shaped by the dynamic interplay of intrinsic chemical reactivity, metabolic transformation and exposure, and microbial modulation. From this standpoint, curcumin functions as a network-level modulator, producing context-dependent outcomes rather than uniform or linear responses. Consequently, it

Non-small cell lung cancer (NSCLC) accounts for 80-85% cases of lung cancer cases. Diagnosis at advanced stages is common, after which therapy-refractory disease progression frequently occurs. Therefore, a better understanding of the molecular mechanisms that control NSCLC progression is necessary to develop new therapies. Overexpression of IκB kinase α (IKKα) in NSCLC correlates with poor patient survival. IKKα is an NF-κB-activating kinase that is important in cell survival and differentiation, but its regulation of oncogenic signaling is not well understood. We recently demonstrated that IK

Abstract The cellular and tissue response to acute hypoxia is mediated by a complex adaptive response initiated by hypoxia-inducible factors (HIF) 1 and 2. HIF proteins are key transcription factors that modulate gene expression to adapt cells to the low oxygen tension. Cellular studies of hypoxia have used the low oxygen model by using hypoxia chambers to monitor the gene expression changes, while others have utilized hypoxia mimetics in normoxic conditions. Here, we provide a comparison of the utility and limitations of two hypoxia mimetics by studying the changes in the miRNA and mRNA expre

A central question in evolutionary biology is what drives the diversification of lineages. Rapid, recent radiations are ideal systems for this question because they still show key morphological and ecological adaptations associated with speciation. While most research on recent radiations focuses on those occurring in insular environments, less attention has been given to continental radiations with complex species interactions.
