Spatial genome organization in nematodes with programmed DNA elimination

This study utilizes Hi-C to reveal that programmed DNA elimination in nematodes involves distinct, species-specific spatial interactions at chromosomal breakage regions that demarcate retained versus eliminated DNA, while demonstrating that the resulting 3D genome reorganization of somatic chromosomes is evolutionarily conserved across *Ascaris* and *Parascaris*.

Systemic Genome Correlation Loss as a Central Characteristic of Spaceflight

This study reveals that spaceflight induces a universal "Systemic Genome Correlation Loss," where the regulatory architecture of the transcriptome undergoes profound decoherence and stochasticity, causing survival-critical networks to remain intact while non-essential systems shatter, thereby shifting the paradigm for astronaut health risks from gene abundance changes to the entropic decay of gene-gene synchronization.

A genome-wide atlas of meiotic recombination intermediates reveals distinct modes of DNA repair that direct crossovers away from transcriptionally marked genes

This study establishes that meiotic cells utilize two distinct DNA repair pathways to direct crossovers away from transcriptionally active genes, thereby safeguarding gene function through an evolutionarily conserved mechanism where early transcriptional context determines whether a double-strand break is resolved as a non-crossover or a crossover.

Systematic identification of seed-driven off-target effects in Perturb-seq experiments

This paper presents a systematic workflow for identifying and filtering seed-driven off-target effects in CRISPRi Perturb-seq experiments by leveraging transcriptional similarity between cells harboring off-target guides and those with direct on-target perturbations, thereby establishing a principled framework to prevent erroneous gene-pathway associations in genome-wide analyses.

Motif-Centered Analyses Reveal Universal and Tissue-Specific Mutagenic Mechanisms Operating in the Human Body

This study analyzes mutation profiles from nearly 12,000 normal human samples across 25 tissues to identify both universal and tissue-specific mutagenic mechanisms, revealing that while clock-like processes and APOBEC activity are widespread, UV-induced mutagenesis is skin-specific and diseased tissues exhibit significantly higher, age-independent mutation accumulation.

Variant-to-gene mapping identifies ARHGEF12 as a primary open-angle glaucoma effector gene operating within retinal ganglion cells

By integrating multi-omics data from trabecular meshwork cells and retinal ganglion cells, this study identifies ARHGEF12 as a primary open-angle glaucoma effector gene, demonstrating that risk-associated homozygosity leads to reduced expression, morphological defects, and disrupted neuronal activity specifically in retinal ganglion cells.

A single-cell and spatial atlas of prostate cancer reveals the combinatorial nature of gene modules underlying lineage plasticity and metastasis

This study presents a comprehensive single-cell and spatial atlas of prostate cancer from 128 patients that reveals how combinatorial gene modules drive lineage plasticity and metastasis, identifies distinct tumor microenvironment features, and introduces a transformer-based foundation model for automated cell-state classification.
