Genetic Diversity of MHC Class I Genes in the Asiatic Ibex (Capra sibirica) along an Altitudinal Gradient

This study presents the first comprehensive analysis of MHC class I genes in the Asiatic ibex, revealing high genetic polymorphism maintained by long-term balancing selection and demonstrating that altitudinal gradients modulate the strength of positive selection on specific alleles likely through differential pathogen pressures.

Mechanistically Informed Prioritization of RNA–LNP Therapeutics: a Safety-by- Design Framework Integrating Virtual Patients, Synthetic Multi-Omics and Biological Consistency Assessment

This paper presents a unified Safety-by-Design computational framework that integrates virtual patient cohorts, mechanistic immune signatures, synthetic multi-omics, and explainable AI to prioritize RNA-LNP formulations by predicting safety scores and validating biological consistency against independent human single-cell data.

The in vitro study of the susceptibility of Bifidobacteria to antidepressants

This in vitro study demonstrates that the serotonin modulator and stimulator Brintellix (vortioxetine) exhibits significantly stronger antimicrobial activity against 22 strains of Bifidobacterium compared to the SSRIs Cipralex and Seropram, suggesting that antidepressant class influences their impact on gut microbiota.

Improving nuclease-and nickase-based homology-directed repair with ZIP CRISPR

The paper introduces ZIP CRISPR, a versatile and cost-effective all-in-one RNP strategy that uses complementary extensions between the gRNA and ssODN template to significantly enhance homology-directed repair efficiency with both Cas9 nuclease and nickase while minimizing genotoxicity.

GDF15 induces GFRAL internalization and lysosomal degradation to impair bovine granulosa cell function through RET–PI3K/AKT suppression and ER stress-associated apoptosis

This study reveals that prolonged GDF15 exposure impairs bovine granulosa cell proliferation, steroidogenesis, and survival by inducing GFRAL internalization and lysosomal degradation, which suppresses the RET–PI3K/AKT signaling pathway and triggers endoplasmic reticulum stress-associated apoptosis.

Genome-Wide m6A Methylation Profiling Reveals Epitranscriptomic Dysregulation in Peripheral Blood Mononuclear Cells from Parkinson's Disease Patients

This study reveals that Parkinson's disease patients exhibit widespread m6A epitranscriptomic remodeling in peripheral blood mononuclear cells, driven by METTL14 downregulation, which correlates with immune pathway dysregulation and the aberrant stabilization of neurodegeneration-associated transcripts.

Morphological variation, morphometric relationships and reproductive observations of the paper nautilus Argonauta hians Lightfoot, 1786 (Cephalopoda: Argonautidae) from the northeastern Arabian Sea, India

This study documents the first quantitative morphometric baseline and reproductive observations for the paper nautilus *Argonauta hians* in Indian waters, confirming its presence off the north-west coast of India through the analysis of seven female specimens and highlighting their negative allometric growth and protracted reproductive cycle.
