Synergistic Impact of miR-126 and miR-143 Variants on Atherosclerosis Risk: A Case- Control Study Integrated with Functional In Silico Annotation

This case-control study demonstrates that the miR-126 rs4636297 and miR-143 rs4705342 polymorphisms individually and synergistically influence atherosclerosis risk in an Iranian population, with functional in silico analysis confirming their regulatory roles in gene expression and splicing.

Microanatomy reveals functional roles of skin bones

By analyzing the microanatomy of osteoderms in Australian Egernia-group lizards using high-resolution µCT, this study demonstrates that specific structural adaptations in these skin bones serve functional roles beyond armor, such as water retention in dry habitats and mechanical reinforcement for burrowing, thereby providing new tools for reconstructing the lifestyles of extinct vertebrates.

Breeding emperor penguins repeatedly use shelf/slope-associated foraging areas across contrasting sea-ice seasons in the northwestern Weddell Sea

This study reveals that breeding emperor penguins from Snow Hill Island in the northwestern Weddell Sea exhibit strong fidelity to specific shelf/slope-associated foraging areas across contrasting sea-ice seasons, with their habitat use influenced by sea-ice concentration and distance from the colony, thereby validating the relevance of the proposed Weddell Sea Marine Protected Area for their conservation.

A genomically validated loss of chromosome Y transcriptional program is a modest prognostic signal independent of tumour stage in male lung adenocarcinoma

In male lung adenocarcinoma, a genomically validated loss of chromosome Y (LOY) transcriptional program serves as a modest, statistically significant prognostic signal that is only marginally independent of tumor stage and is largely confounded by generic proliferation, limiting its immediate utility as a standalone clinical biomarker.

CHAP-GWAS: Leveraging Chromosomal Haplotypes to Improve Genome-Wide Association Studies

The paper introduces CHAP-GWAS, a novel, phenotype-driven algorithm that leverages chromosome-scale haplotypes to dynamically define trait-associated blocks, thereby significantly improving statistical power and identifying genetic loci missed by conventional single-SNP and static haplotype-based GWAS methods.

Identification and functional analysis of the TOPLESS-related co-repressor CcTPR4 in jute: a negative regulator of fiber yield through modulation of cellulose biosynthesis and gibberellin homeostasis

This study identifies and functionally characterizes CcTPR4 as a negative regulator of jute fiber yield that suppresses cellulose biosynthesis and modulates gibberellin homeostasis, establishing it as a key target for molecular breeding.

A brain splicing-QTL colocalization map of candidate effector genes for major depressive disorder

By integrating a large-scale major depressive disorder GWAS with a comprehensive human brain splicing-QTL resource, this study identifies 56 high-confidence candidate effector genes whose disease associations are more clearly resolved through alternative splicing than through gene expression alone, offering a complementary regulatory layer for functional and translational prioritization.

Shared Genetic Architecture of Premenstrual Disorder and Postpartum Depression: Registry-Based and Genetic Evidence

This study provides the first evidence of a substantial shared genetic architecture between premenstrual disorder and postpartum depression through registry-based and genomic analyses, identifying novel risk loci in *PCDH9* and *KCTD16* that implicate GABA-mediated inhibitory signaling and hippocampal regulation in the abnormal brain response to hormonal fluctuations.
