Mitochondrial DNA-cGAS-STING-CISD1 axis mediates hypoxia-induced cognitive impairment by driving hippocampal neuronal ferroptosis

This study reveals that high-altitude hypoxia induces hippocampal neuronal ferroptosis and cognitive impairment through a self-amplifying axis where mitochondrial damage triggers mtDNA release to activate the cGAS-STING pathway, which interacts with CISD1 to drive ferroptosis, a mechanism validated across mouse models and human cohorts.

Effects of chemical properties of mixed leaf litter, phyllosphere microbial communities, and leaf litter decomposition

This study demonstrates that mixing leaf litter from different tree species reshapes phyllosphere microbial communities and exhibits intermediate effects on chemical properties, ultimately influencing litter decomposition rates and nutrient cycling in forest ecosystems.

Synthesis, characterization, and molecular docking of ES/CA/Cs nanocomposite as a potential nanocarrier for gene delivery: a preliminary study

This preliminary study synthesizes and characterizes an Eggshell/Citric Acid/Chitosan (ES/CA/Cs) nanocomposite as a potential gene delivery carrier, using molecular docking to predict its favorable interaction with the AtRCCR enzyme while highlighting the need for future biological validation to confirm its efficacy in treating renal cell carcinoma.

Systematic Evaluation of Short-Read, Long-Read, and Microarray Platforms for Integrated Genomic and Epigenomic Profiling in Brain Tumors

This study systematically evaluates short-read sequencing, long-read Oxford Nanopore Technologies, and EPICv2 microarrays for brain tumor profiling, concluding that while short-read sequencing offers superior scalability and accuracy for somatic variants, long-read sequencing provides unique advantages in resolving problematic genomic regions and haplotype-specific methylation, with all platforms demonstrating high concordance in methylation measurements.

Endophyte-Mediated Elicitation Enhances Picrosides Production in Suspension Cultures of Picrorhiza kurroa Royle ex Benth

This study demonstrates that eliciting suspension cultures of *Picrorhiza kurroa* with mycelial extracts from endophytic fungi, particularly *Fusarium acuminatum* (EE2), significantly enhances the concentration-dependent and tissue-specific production of valuable picrosides and their precursors.

Deciphering Accelerated Biological Ageing in Breast Cancer Survivors and Cancer-Free Women Using Explainable Machine Learning

This study employs an explainable machine learning framework to identify distinct, multidimensional factors driving accelerated biological ageing in breast cancer survivors compared to cancer-free women, revealing unique associations such as impaired functional status and radiotherapy in survivors versus physical fitness and diet in controls, thereby paving the way for targeted survivorship care.

Gut microbiota ablation depletes secondary bile acids and shifts the cytokine balance in BCG-infected mice

Using a novel four-arm mouse model with independent ablation and transplantation branches, this study demonstrates that antibiotic-mediated gut microbiota depletion specifically eliminates secondary bile acids and drives a pro-inflammatory cytokine shift in BCG-infected mice, establishing a direct link between the gut community, its metabolites, and the host immune response.
