Probiotic‐Derived Vesicles Rectally Delivered via Thermo‐Gelling Copolymer Promote Mucosal Healing and Reduce Inflammation in Ulcerative Colitis

Advanced Science, EarlyView.
A thermo‐responsive rectal delivery platform integrating probiotic‐derived extracellular vesicles within a hyaluronic acid‐based copolymer enables localized and sustained therapy for ulcerative colitis. The formulation effectively suppresses inflammation, promotes macrophage polarization toward a regenerative phenotype, restores epithelial barrier ...

Dietary Trehalose Activates Autophagy Potentially Via MAPK Signaling Pathway to Alleviate Oxidative Stress Induced by Air Exposure Stress in Chinese Mitten Crab (Eriocheir sinensis)

Aquaculture Nutrition
Air exposure stress (AES) is a common stress faced by Chinese mitten crabs (Eriocheir sinensis) in aquaculture and transport. This study was designed to evaluate the levels of endogenous trehalose, oxidative stress, and autophagy in crabs subjected to ...

Trehalose and α-glucan mediate distinct abiotic stress responses in Pseudomonas aeruginosa.

PLoS Genetics, 2021
An important prelude to bacterial infection is the ability of a pathogen to survive independently of the host and to withstand environmental stress. The compatible solute trehalose has previously been connected with diverse abiotic stress tolerances ...

Cancer‐Associated BCL‐2 Mutants Reveal Mechanisms Towards Venetoclax Resistance

Advanced Science, EarlyView.
Venetoclax (VEN) resistance in chronic lymphocytic leukemia arises from diverse BCL2 mutations. We map mechanisms contributing to VEN resistance across common BCL‐2 variants. G101V and D103Y reduce drug binding and increase sequestration of pro‐apoptotic proteins. V156D blocks VEN allosterically.

Adaptation of Echinococcus Multilocularis to Oxidative Stress Depends on EmPDK‐Mediated Metabolic Reprogramming

Advanced Science, EarlyView.
Metabolic adaption presents a vital survival strategy for E. multilocularis. This study identifies EmPDK as a central metabolic regulator governing glucose metabolic reprogramming. Oxidative stress activates EmHIF1α to induce EmPDK expression. Mechanistic characterization reveals this ROS/EmHIF1α/EmPDK axis drives glycolytic reprogramming to sustain ...

Gestational Hypoxia Disrupts Medial Ganglionic Eminence Progenitor Dynamics and Interneuron Development in Schizophrenia

Advanced Science, EarlyView.
FES‐derived MGE spheroids exhibit progenitor‐stage alterations in developmental trajectory and hypoxia‐responsive transcriptional programs, followed by functional disruption. Gestational hypoxia recapitulates impaired progenitor proliferation, shortened cell‐cycle progression, interneuron developmental abnormalities, and schizophrenia‐like behaviors in

Exogenous Carbohydrate Effects on Thermoadaptation and Thermostress in Ogataea parapolymorpha Under Different Carbon Sources

Fermentation
Thermotolerant methylotrophic yeast Ogataea parapolymorpha is a promising host for high-temperature bioprocesses, yet the effects of carbon source and exogenous carbohydrates on their heat response remain poorly understood.

Improving the Physicochemical Properties, Organic Acids, Amino Acids, Volatile Organic Compounds, and Metabolites of Laohan Melon Juice Through Fermentation With Different Lactic Acid Bacteria

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Fermentation with lactic acid bacteria could improve amino acids, volatile organic compounds (VOCs), and nonvolatile metabolites of Laohan melon juice (LMJ), which provides theoretical guidance for the development of Laohan melon beverage and advances knowledge of the metabolic mechanisms of VOCs in LMJ.

Strategies to reduce osmotic stress during cryopreservation of red blood cells when using trehalose

Scientific Reports
The aim of this study was to determine optimal conditions for cryopreserving red blood cells (RBCs) using trehalose. We assessed the extent of trehalose uptake by RBCs during incubation at 37 °C and following freezing-and-thawing.

Effects of Trehalose Preconditioning on H9C2 Cell Viability and Autophagy Activation in a Model of Donation after Circulatory Death for Heart Transplantation

Current Issues in Molecular Biology
Donation after circulatory death (DCD) is a promising strategy for alleviating donor shortage in heart transplantation. Trehalose, an autophagy inducer, has been shown to be cardioprotective in an ischemia-reperfusion (IR) model; however, its role in IR ...
