Human Umbilical Cord Mesenchymal Stem Cells Treat Photoaged Mouse Skin through the Mitochondrial Autophagy Pathway

This study demonstrates that human umbilical cord mesenchymal stem cells (hUC-MSCs) effectively treat photoaged mouse skin and associated systemic organ damage by restoring mitochondrial autophagy, with combined local and tail-vein injection proving to be the most effective therapeutic strategy.

Exploring the prognostic value of N4-acetylcytosine- modified genes in colorectal cancer using transcriptomics combined with single-cell data

This study integrates bulk and single-cell transcriptomics to identify a seven-gene N4-acetylcytosine modification-related signature that effectively stratifies colorectal cancer patients into high- and low-risk groups while revealing distinct immune infiltration patterns, pathway enrichments, and key cellular differentiation trajectories to guide potential therapeutic strategies.

PathwayBench: a multi-criterion benchmark of pseudobulk pathway activity scoring methods reveals rank-window competition as a mechanism of biological signal loss in single-cell RNA-seq

PathwayBench introduces a comprehensive multi-criterion benchmark revealing that "rank-window competition" causes biological signal loss and direction inversion in rank-based pathway scoring methods, thereby guiding evidence-based method selection for pseudobulk single-cell RNA-seq analyses.

Flagellar Oncogenicity in the Hypocomplement–Tumour Holobiont: A Five-Prediction Hypothesis Paper on Bacterial Flagella as Effectors of Virus-Driven and Coinfection-Driven Carcinogenesis

This hypothesis paper proposes that bacterial flagella serve as the primary effectors of viral and coinfection-driven carcinogenesis within the tumor microbiome by linking flagellar biology, complement evasion, and microbial dominance, and outlines five testable predictions plus a sixth extended hypothesis to guide future immuno-oncology research.
