Low-Magnitude Mechanical Loading Modulates Age-Related Changes in the Temporomandibular Joint via TRPV4

This study demonstrates that long-term low-magnitude mechanical loading exacerbates age-related temporomandibular joint degeneration by downregulating TRPV4, which in turn suppresses chondrogenic factors like SOX9 and disrupts extracellular matrix metabolism.

MEFV genotype distribution and allele frequencies in familial Mediterranean fever: a 20-year retrospective study of 2,246 individuals from a Palestinian laboratory archive

This 20-year retrospective study of 2,246 individuals from a Palestinian laboratory archive reveals that nearly half of the tested population carries *MEFV* variants, with five specific mutations—led by the unusually prevalent V726A—accounting for over 94% of the genetic burden, thereby supporting the implementation of focused screening and genetic counseling strategies for Familial Mediterranean Fever in this high-prevalence population.

Prognostic Value, Immune Microenvironment Remodeling, and Drug Sensitivity of MIOX in Breast Cancer: A Multi‑Cohort Bioinformatics Analysis

This multi-cohort bioinformatics study identifies Myo-inositol oxygenase (MIOX) as an independent poor prognostic biomarker in breast cancer that drives cell cycle progression, remodels the immune microenvironment into a state of coexisting activation and suppression, and predicts sensitivity to specific targeted therapies.

Genome-wide identification and comparative analysis of endogenous retroviruses across five breed-representative pig assemblies

This study establishes a comprehensive, breed-resolved pan-genome framework for porcine endogenous retroviruses (ERVs) across five pig assemblies, revealing that while most ERVs are degraded, a core set of breed-shared, tissue-specific ERV-associated genes overlaps with key agricultural QTLs and offers critical benchmarks for improving xenotransplantation safety.

Structural and functional dissection of ASCT2 interaction with Syncytin-1 mediating cell-cell fusion

This study utilizes cryo-EM and functional assays to reveal how Syncytin-1 selectively binds the ASCT2 transporter in an outward-oriented, asymmetric state that enables cell-cell fusion while preserving residual transport activity, a specificity dictated by a broad interaction interface rather than single residues.
