Construction of Trans-4-hydroxy-L-proline-producing Escherichia coli and Optimization of Fermentation Conditions

open access: yesFermentation
In this study, we combined the citric acid cycle with the biosynthesis pathways of L-proline and L-hydroxyproline to construct a strain that produces L-hydroxyproline directly from glucose and other raw materials, without the addition of L-proline and α ...

Optimized Monothiol Thioredoxin Derivative (ORP100S) Protects In Vitro and In Vivo from Radiation and Chemotoxicity Without Promoting Tumor Proliferation

open access: yesAdvanced Science, EarlyView.
Native thioredoxin‐1 (TRX) stimulates proliferation and rescues stem cells and cancer cells from multiple stressors by suppressing p53 and inhibiting ferroptosis via GPX4/SLC7A11 upregulation mediated by enhanced KLF4 expression and p53 promoter binding.

One‐Step Drug Screening System Utilizing Electrophysiological Activity in Multiple Brain Organoids

open access: yesAdvanced Science, EarlyView.
This study presents a one‐step system that delivers different drug doses to brain organoids and monitors their neural activity using integrated 3D microelectrodes. By combining dose‐specific microfluidic delivery with high‐resolution electrophysiological recording, the platform enables simultaneous, real‐time screening of neural responses across ...

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

open access: yesAdvanced Science, EarlyView.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

Effects of Carbohydrates, Prebiotics and Salts on Survival of Saccharomyces boulardii During Freeze-Drying

open access: yesActa Universitatis Cibiniensis. Series E: Food Technology, 2018
Saccharomyces boulardii, as a probiotic yeast, had been commonly used in food, medicine and feed to treat diarrhea in humans or livestock. However, there are few researches focusing on the preparation of its freeze-drying S.boulardii powder.

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

open access: yesAdvanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...
