Single-cell and multi-layer analysis identifies state-restricted stromal remodeling in steroid-associated osteonecrosis of the femoral head

This study employs a multi-layer analytical strategy to reveal that stromal remodeling in steroid-associated osteonecrosis of the femoral head is a state-restricted, context-sensitive process where adipogenic rewiring is only partially coupled to a specific stress-adaptation program, rather than a uniform compartment-wide phenotype.

A genetically marked maggot to better understand corpse decomposition ecology

This study successfully developed a genetically marked *Phormia regina* blow fly strain expressing a fluorescent protein that retains normal development rates, thereby overcoming the technical barrier of tracking known-age larvae in the field to validate forensic age-estimation methods under realistic decomposition conditions.

Plasma Proteomic Profiling Reveals Divergent Molecular Pathways in Aging and Alzheimer’s Disease

This study utilizes plasma proteomic profiling to demonstrate that the molecular pathways driving Alzheimer's disease and cognitive decline are distinct from those of normal aging, revealing unique signatures in immune, actin, and platelet-related proteins that offer new candidate biomarkers and therapeutic targets.

Lineage Memory and Convergent Adaptation Dictate the Single-Cell and Spatial Architecture of Brain Malignancies

By integrating the largest single-cell and spatial atlas of brain malignancies, this study reveals that tumor evolution is driven by a balance of lineage-specific imprinting and convergent adaptation to a dominant mesenchymal state, which orchestrates distinct microenvironmental shifts and defines a specific proliferative niche that predicts severe clinical deterioration.

Transcriptional signatures of nitrogen and amino acid metabolism under excess ammonium stress in Nicotiana tabacum leaves

This study reveals that excess ammonium stress in *Nicotiana tabacum* triggers growth inhibition and metabolic shifts characterized by specific amino acid alterations and distinct transcriptional reprogramming, ultimately identifying six candidate transcription factors that regulate the plant's response to ammonium toxicity.
