Eosinophils‐Induced Lumican Secretion by Synovial Fibroblasts Alleviates Cartilage Degradation via the TGF‐β Pathway Mediated by Anxa1 Binding

Advanced Science, EarlyView.
Eosinophils play a crucial role in the progression of temporomandibular joint osteoarthritis (TMJOA). This study demonstrates that eosinophils, induced by OVA/IL‐5, promote Lumican secretion in the synovium, which binds to Annexin A1 in chondrocytes, inhibiting transforming growth factor β2 and Smad2/3 phosphorylation.

Model‐Guided Rational Construction of Escherichia coli Synthetic Consortia for Enhanced 2‐Methylbutyric Acid Production

Advanced Science, EarlyView.
We developed a citramalate‐derived pathway for 2‐methylbutyric acid production in E. coli mono‐culture and consortia. The optimized consortium, using 2‐keto‐3‐methylvalerate as a node, achieved 1817.03 ± 103.73 mg L−1 2‐methylbutyric acid, a 28‐fold increase from the initial strain, with a yield of 0.091 g/g glucose.

AhR‐Dependent Induction of β‐Defensin 1 in Colonic Epithelial Cells Regulates Cross‐Talk between Gut Microbiota and Immune Response Leading to Attenuation of Colitis

Advanced Science, EarlyView.
This study identifies a key signaling pathway involving the environmental sensor AhR and antimicrobial peptides, such as BD‐1, in the regulation of intestinal homeostasis. It highlights the role of BD‐1 in regulating gut microbiota and the intestinal immune response.

Contrasting recovery of metagenome‑assembled genomes and derived bacterial communities and functional profiles from lizard fecal and cloacal samples

Animal Microbiome
Genome-resolved metagenomics, based on shotgun sequencing, has become a powerful strategy for investigating animal-associated bacterial communities, due its heightened capability for delivering detailed taxonomic, phylogenetic, and functional insights ...

Exploring gene content with pangene graphs [PDF]

arXiv
Motivation: The gene content regulates the biology of an organism. It varies between species and between individuals of the same species. Although tools have been developed to identify gene content changes in bacterial genomes, none is applicable to collections of large eukaryotic genomes such as the human pangenome.

Gelsolin's Protective Role in MASH through F‐Actin Regulation and P53 Degradation

Advanced Science, EarlyView.
Gelsolin (GSN) maintains liver metabolic homeostasis by promoting MDM2‐mediated P53 degradation and inhibiting F‐actin/Yes‐associated protein (YAP) overactivation. Loss of GSN impairs P53 degradation, increases lipid deposition, and enhances YAP‐driven fibrosis and inflammation in metabolic‐associated steatohepatitis.

Nuclear‐Localized BCKDK Facilitates Homologous Recombination Repair to Support Breast Cancer Progression and Therapy Resistance

Advanced Science, EarlyView.
Under DNA damage, tumor cells rely on efficient DNA repair for survival and therapy resistance. This study has demonstrated that BCKDK localizes to breast cancer cell nuclei, where it binds to and phosphorylates RNF8, thereby blocking ubiquitin‐mediated degradation of RAD51 and enhancing HRR. A selective BCKDK inhibitor synergizes with clinical agents,

An Engineered PfAgo with Wide Catalytic Temperature Range and Substrate Spectrum

Advanced Science, EarlyView.
This work presents a strategy for engineering thermophilic Ago proteins to obtain wide catalytic temperature range and broad substrate spectrum. This strategy is applied to engineer PfAgo and TtdAgo, and the biochemical properties of the engineered PfAgo are systematically characterized. The study further elucidates the structural differences involved.

Bacterial Genomes

Microbes form the “unseen majority” of life on Earth, with bacteria at the forefront as both the architects of life’s chemical foundations and agents of disease. But their story is far more complex. Bacteria thrive in diverse and extreme environments, driven by the dynamic evolution of their genomes.
