16S rRNA Gene Survey of Microbial Communities in Winogradsky Columns

open access: yesPLoS ONE, 2014
A Winogradsky column is a clear glass or plastic column filled with enriched sediment. Over time, microbial communities in the sediment grow in a stratified ecosystem with an oxic top layer and anoxic sub-surface layers. Winogradsky columns have been used extensively to demonstrate microbial nutrient cycling and metabolic diversity in undergraduate ...

Neuroprotective Effects of Time‐Restricted Feeding Combined With Different Protein Sources in MPTP‐Induced Parkinson's Disease Mice Model and Its Modulatory Impact on Gut Microbiota Metabolism

open access: yesAdvanced Science, EarlyView.
Time‐restricted feeding (TRF) exerts protein‐dependent neuroprotective effects in an MPTP‐induced Parkinson's disease model. In casein‐fed mice, TRF improves gut barrier integrity and reduces neuroinflammation, possibly via modulation of Allobaculum and BCAAs.

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

open access: yesAdvanced 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.

Developmentally Inspired, Mechanical–Metabolic Dual Gradient Osteochondral Constructs Bridging Regeneration and Therapeutic Screening

open access: yesAdvanced Science, EarlyView.
A developmentally inspired osteochondral construct integrates mechanical and metabolic dual gradients within a 3D‐printed platform. Human MSC spheroids are spatially directed to form cartilage–bone interfaces, enabling evaluation of regeneration without biochemical reagents and assessment of drug responses. This physiologically relevant, phase‐specific

Bacterial Community Reconstruction Using A Single Sequencing Reaction [PDF]

open access: yes, 2010
Bacteria are the unseen majority on our planet, with millions of species and comprising most of the living protoplasm. While current methods enable in-depth study of a small number of communities, a simple tool for breadth studies of bacterial population

Sphingomonas paucimobilis‐Driven Epithelial–Endothelial Transition in Adenomyosis Pathogenesis

open access: yesAdvanced 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 ...

Alternating High‐Fat and Polysaccharide Diets Modulates Gut Phage‐Bacterial Interplay

open access: yesAdvanced Science, EarlyView.
This study reveals how alternating high‐fat and polysaccharide diets reshape the human gut virome and enhance phage‐bacteria interactions. Using large‐scale metagenomic meta‐analysis and a time‐resolved mouse model, the authors show that diets strongly modulate phage abundance, lifestyle, and gene exchange, offering new insights into nutrition‐guided ...

Genome‐Wide Association Study Reveals Insect Genetics and Microbial Symbiont Effects on Susceptibility of Diaphorina citri to the Citrus Greening Pathogen, Candidatus Liberibacter Asiaticus

open access: yesAdvanced Science, EarlyView.
This study investigates the genetic and microbial factors influencing the susceptibility of Diaphorina citri to the citrus greening pathogen Candidatus Liberibacter asiaticus (CLas), employing a microbiome Genome Wide Association Study. The research identifies a key gene encoding an MFS‐type transporter contributing to CLas infectivity and abundance in

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

open access: yesAdvanced 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

The Gut Commensal Butyricimonas Virosa Modulates Gut Microbiota‐Dependent Thiamine Metabolism and Attenuates Mouse Steatotic Liver Disease

open access: yesAdvanced Science, EarlyView.
This study reveals that dietary stachyose enriches Butyricimonas virosa, effectively attenuating metabolic dysfunction‐associated steatotic liver disease (MASLD). Mechanistically, B. virosa enhances gut thiamine monophosphate synthesis, which elevates hepatic thiamine pyrophosphate levels.
