TH/TRs–COL11A2 Axis Mediates Loss of a Differentiated Astrocyte State in Hypogyrified Brains

Advanced Science, EarlyView.
Using a gyrencephalic congenital hypothyroidism pig model, this study reveals cerebral atrophy and cortical hypogyrification. Single‐cell sequencing identifies astrocytes as major TH‐responsive cells, with the COL11A2‐enriched Astro‐2 state nearly absent.

The role of glutamine in leukemia cell metabolism

Leukemia is a heterogeneous group of hematological malignancies that result from the abnormal proliferation of immature blood cells. One of the hallmarks of tumor cells is their altered metabolism.

Hierarchical Flux‐Protection Engineering Stabilizes Oxidation‐Prone Metabolic Nodes for High‐Level Curcumin Biosynthesis

Advanced Science, EarlyView.
Flux‐protection engineering stabilizes an oxidation‐prone L‐DOPA node in engineered E. coli by combining acid‐adapted chassis evolution, respiratory‐chain modulation, enzyme‐level flux matching, and pH–DO control. Carbon is redirected from oxidative browning to productive biosynthesis, enabling 1075.2 mg/L curcumin and demonstrating transferability to ...

E2F1 regulates glutamine metabolism in mouse embryonic fibroblasts (MEFs)

, 2020
E2F1 is well known as an oncogene for its role in controlling cell proliferation. However, this transcription factor is also involved in contrasting roles such as apoptosis, DNA repair and cell differentiation.

Restoring Endothelial Mitochondrial Homeostasis With a Bioactive Nanoshield Promotes Vascular Regeneration on Cardiovascular Implants

Advanced Science, EarlyView.
A bioactive poly(citrate‐polyglycol‐procyanidin) (PCGP) nanoshield is developed for cardiovascular implants to restore endothelial mitochondrial homeostasis following vascular injury. By preserving mitochondrial integrity, re‐establishing metabolic balance, and activating PI3K/Akt/eNOS‐NO signaling, the PCGP interface promotes functional endothelial ...

Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

Advanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

Advanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...

An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management

Advanced Science, EarlyView.
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

Upadacitinib Restrains the Pathogenic Fitness of CD4+ T Cells and Aberrant B Cell Programming in Optic Neuritis

Advanced Science, EarlyView.
Single‐cell profiling and functional perturbation reveal coordinated JAK1‐pSTAT3 downstream programs in optic neuritis, including MCL1‐dependent fitness of pathogenic CD4+ Tem cells and glycolysis‐linked, cholesterol‐sensitive B‐cell responses associated with RORA. Upadacitinib disrupts this reciprocal T‐B‐cell circuit and alleviates neuroinflammation,

SIRT5‐Mediated Desuccinylation of ACAA2 Protects Against Calcium Oxalate‐Induced Kidney Injury by Regulating Fatty Acid Oxidation to Suppress Mitochondrial Oxidative Injury and Ferroptosis

Advanced Science, EarlyView.
The SIRT5/ACAA2 axis maintains lipid metabolic homeostasis in RTECs by promoting ACAA2 desuccinylation and preserving its stability and enzymatic activity, thereby sustaining FAO and limiting PUFA and PUFA‐containing phospholipid accumulation. Under CaOx stress, SIRT5 downregulation impairs FAO, promotes oxidative stress and ferroptosis, and enhances ...
