Toward a Safer Live Vaccine: Targeting the Key Gene EtMob1 to Block Sporogony in Eimeria tenella

This study identifies EtMob1 as a critical regulator of *Eimeria tenella* sporogony and demonstrates that generating an EtMob1-deficient strain via CRISPR/Cas9 and IAA-inducible degradation effectively attenuates pathogenicity while inducing protective immunity, establishing it as a promising candidate for a safer live vaccine against avian coccidiosis.

Integrative Mendelian Randomization and Single-Cell Transcriptomic Analyses Reveal Ferroptosis-Related Protective Genes and Tumor Microenvironmental Remodeling in Colorectal Cancer

This study integrates Mendelian randomization, bulk, and single-cell transcriptomic analyses to identify four ferroptosis-related genes (AKR1C2, MAPK3, MAP3K11, and CDKN1A) as genetically protective factors in colorectal cancer that are downregulated in tumors and linked to critical tumor microenvironment remodeling, including immune infiltration, endothelial transition, and intercellular communication.

Elevated East Eurasian Maternal Genetic Ancestry in the Haryana Jaat Population: Insights from Mitochondrial DNA Haplogroup Distribution and Comparative Analysis

This study reveals that the Haryana Jaat population possesses a unique tripartite maternal genetic structure dominated by South Asian lineages with significant West Eurasian contributions and a distinctive 7.65% East Eurasian ancestry (primarily haplogroup D) that sets them apart from neighboring groups like the Ror, Gujjar, and Kamboj.

CrRAP2.2 reprograms transcriptional networks associated with vascular cell wall remodeling and stress responses in Citrus

This study demonstrates that overexpressing the transcription factor CrRAP2.2 in citrus reprograms defense-related transcriptional networks to enhance vascular cell wall reinforcement through lignin deposition, thereby establishing a mechanistic link between this factor and resistance against *Xylella fastidiosa*.

Dietary volatile molecules orchestrate microbiome-mitochondrial crosstalk via tryptophan metabolism to resolve intestinal stress

This study demonstrates that black tea volatile fractions (BTVs) alleviate alcohol-induced intestinal stress in rats by remodeling the gut microbiota to drive tryptophan metabolism toward NAD⁺ biosynthesis, thereby restoring mitochondrial function and suppressing pyroptosis to preserve gut barrier integrity.
