Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

Advanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Dietary Mannan‐Rich Fractions Attenuate Weaning Stress in Piglets via Modulating Gut Microbiota and TLR5/NF‐κB Signaling

Animal Research and One Health, EarlyView.
This study aimed to investigate the potential of a mannan‐rich fraction (MRF) as a dietary intervention to alleviate weaning stress in piglets. Our results revealed that MRF could alleviate weaning stress by modulating the gut microbiota and the TLR5/NF‐κB signaling pathway, offering a novel and sustainable alternative to antibiotic use in swine ...

The involvement of Srs2 in post-replication repair and homologous recombination in fission yeast [PDF]

Nucleic Acids Research, 2004
Homologous recombination is important for the repair of double-strand breaks and daughter strand gaps, and also helps restart stalled and collapsed replication forks. However, sometimes recombination is inappropriate and can have deleterious consequences.

Controllable engineered probiotic microspheres for treating ulcerative colitis: A cascade enzyme‐catalyzed strategy to restore intestinal redox homeostasis

BMEMat, EarlyView.
A dual strategy integrating genetic engineering and physical encapsulation was proposed to enhance the cell viability and antioxidant properties of probiotics. The cascade antioxidant enzymes released from probiotic microspheres restore intestinal redox homeostasis by eliminating intestinal reactive oxygen species for ulcerative colitis treatment ...

Checkpoint and recombination pathways independently suppress rates of spontaneous homology-directed chromosomal translocations in budding yeast

Frontiers in Genetics
Homologous recombination between short repeated sequences, such as Alu sequences, can generate pathogenic chromosomal rearrangements. We used budding yeast to measure homologous recombination between short repeated his3 sequences located on non ...

Increased Insulin Action, Glucose Metabolism and Muscle Function in Supervillin‐Knockout and Supervillin‐Mutant Mice

Cytoskeleton, EarlyView.
ABSTRACT We here describe mouse models with complementary homozygous Svil mutations. In skeletal muscle, Svil‐Mut mice express the Svil‐encoded N‐terminus fused to the βgal‐neo gene‐trap tag and lack the highly conserved archvillin C‐terminus; Svil‐KO mice lack expression of all known Svil‐encoded proteins; and Svil‐LoxP mice contain loxP sites for ...

Use of an on/off tetracycline riboswitch to control protein production in Komagataella phaffii

AMB Express, 2023
The methylotrophic yeast Komagataella phaffii is one of the most important microbial platforms to produce recombinant proteins. Despite its importance in the context of industrial biotechnology, the use of synthetic biology approaches in K.

Monitoring and Mitigation Strategies for Hazardous Compounds in Chinese Rice Wine (Huangjiu): A Comprehensive Review

Food Safety and Health, EarlyView.
This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.

Genome‐wide identification of the bZIP transcription factor family in sainfoin (Onobrychis viciifolia Scop.) and expression profiles in response to aluminum stress

Grassland Research, EarlyView.
Sainfoin is an important forage legume with potential for cultivation in stressful environments, but its molecular response to aluminum toxicity remains unclear. This study identified 236 basic leucine zipper (bZIP) transcription factor genes in sainfoin and analyzed their evolutionary features and regulatory potential.
