Nitrous oxide production in soil isolates of nitrate-ammonifying bacteria [PDF]

, 2012
Here we provide the first demonstration of the potential for N2O production by soil-isolated nitrate-ammonifying bacteria under different C and N availabilities, building on characterizations informed from model strains.

Oral Streptococcus salivarius Couples Neutrophil IRGM1 Signaling to NET Formation and Colorectal Cancer Metastasis

Advanced Science, EarlyView.
The oral bacterium Streptococcus salivarius promotes colorectal cancer metastasis by inducing neutrophil extracellular trap (NET) formation. Mechanistically, IRGM1–IQGAP1 interaction activates Wnt5a–PI3K/AKT signaling in neutrophils, driving NET‐mediated tumor progression.

Inefficient Secretion of Anti-sigma Factor FlgM Inhibits Bacterial Motility at High Temperature

iScience, 2019
Summary: Temperature is one of the key cues that enable microorganisms to adjust their physiology in response to environmental changes. Here we show that motility is the major cellular function of Escherichia coli that is differentially regulated between

Sphingomonas paucimobilis‐Driven Epithelial–Endothelial Transition in Adenomyosis Pathogenesis

Advanced Science, EarlyView.
This study identifies epithelial–endothelial transition (EET) as a novel adenomyosis pathogenic mechanism driven by Sphingomonas paucimobilis colonization. Systematic inhibitor experiments validate a TNFα→NF‐κB→MMP signaling cascade essential for EET. Critically, bacterial culture supernatant fails to induce pathological changes, demonstrating viable ...

Mitochondrial CircRNA CircMT‐RNR2 Safeguards Antioxidant Defense to Support Fibroblast Functions in Wound Repair

Advanced Science, EarlyView.
CircMT‐RNR2 promotes wound healing by enhancing fibroblast proliferation, migration, contraction, and extracellular matrix (ECM) production. It sustains mitochondrial redox balance by stabilizing the antioxidant protein PRDX3, thereby reducing ROS‐induced damage. In diabetic foot ulcers, hypoxia, hyperglycemia, and reduced FGF2 and EGF expression lower
