Mitochondrial diversity and demographic history of Arctica islandica (Bivalvia: Venerida) in the German waters of the Baltic Sea

This study reveals that *Arctica islandica* populations in the German Baltic Sea exhibit high mitochondrial diversity and a history of postglacial expansion without significant regional genetic structuring, indicating they share widespread lineages with the broader amphi-Atlantic species range despite inhabiting distinct brackish environments.

Ancestry-Associated Distribution of IL6, IL1B, and TNF Variants Reveals Differential Genetic Susceptibility to Inflammatory Diseases

This study reveals significant ancestry-associated differences in the distribution of inflammatory gene variants (IL6, IL1B, and TNF) between Mexican Mestizo and Indigenous populations, with Indigenous groups showing lower frequencies of risk alleles compared to Mestizos and Europeans, thereby underscoring the necessity of ancestry-informed approaches for assessing inflammatory disease susceptibility.

Integrating Molecular Diagnostics and Interpretable Machine Learning to Identify Genetic Drivers of Drug-Resistant Mycobacterium tuberculosis

This study demonstrates that integrating interpretable machine learning models with routine cycle threshold (Ct) molecular data from *Mycobacterium tuberculosis* isolates in rural Eastern Cape can accurately predict drug resistance patterns and identify key genetic drivers, offering a scalable framework to enhance tuberculosis management in high-burden, resource-limited settings.

An APOD-EFEMP1-COL5A2 fibroblast programme marks a matrix-remodelling, vascular and myeloid-associated niche linked to adverse gastric cancer outcomes

This study integrates multi-omics data to identify an APOD-EFEMP1-COL5A2 fibroblast programme in gastric cancer that defines a matrix-remodelling, vascular, and myeloid-associated niche linked to adverse clinical outcomes and suggests testable mechanistic hypotheses for therapeutic intervention.

Construction of a Molecular Traceability and Identification System for Edible Rose and Its Analogues Using Chloroplast Genomes and DNA Barcoding

This study establishes a robust molecular traceability system for authenticating edible *Rosa rugosa* and distinguishing it from adulterants by integrating chloroplast genomic analysis, ITS2 DNA barcoding with secondary structure, and chemical profiling to address supply chain traceability and quality screening needs.

Thermal landscapes reorganize movement through behavioural-state transitions in an endangered ungulate

This study demonstrates that thermal landscapes reshape the movement of endangered hirola antelope through predictable, nonlinear transitions among distinct behavioral states—specifically a shift toward resting above a 33°C threshold—rather than a uniform suppression of activity, offering a mechanistic framework for predicting wildlife responses to climate change and guiding conservation strategies.

CRISPR/Cas9-Mediated Knockout of LXRα and LXRß in MCF-7 Breast Cancer Cells, Revealing Their Roles in Target Gene Regulation and Cell Proliferation

This study utilized CRISPR/Cas9 technology to generate LXRα, LXRβ, and dual knockout MCF-7 breast cancer cell lines, demonstrating that the loss of LXR function disrupts the regulation of target genes like ABCA1 and ABCG1 while increasing basal cell proliferation and reducing sensitivity to LXR agonist-induced growth inhibition.

ALDOB influences β-cell insulin secretion through modulating GLP-1R signaling in type 2 diabetes

This study reveals that ALDOB modulates β-cell insulin secretion in type 2 diabetes by interacting with IGFBP5 to regulate GNAI2 transcription and tune GLP-1R-cAMP-PKA signaling, offering a potential therapeutic strategy to overcome GLP-1R desensitization.

High-resolution assessment of fecal microbiome integrity across practical storage conditions and extreme treatments

This study demonstrates that while standard fecal sample storage variations up to 11 days preserve microbial community integrity, extreme treatments like autoclaving and UV exposure cause catastrophic DNA degradation and artifactual community shifts, thereby validating flexible handling protocols for large-scale microbiome research.
