Tailoring a Functional Synthetic Microbial Community Alleviates Fusobacterium nucleatum‐infected Colorectal Cancer via Ecological Control

open access: yesAdvanced Science, EarlyView.
The bottom‐up strategy based on multiomics data is used for the SynCom design, and it successfully inhibited F. nucleatum growth and achieved stable colonization in vivo. In addition, it promoted tryptophan metabolism and secondary bile acid conversion, reduced lipid accumulation, relieved microbiome disorder, decreased inflammatory reaction, and ...

Nuclear Translocation of S100A9 Triggers Senescence of Human Amnion Fibroblasts by De‐Repressing LINE1 Via Heterochromatin Erosion at Parturition

open access: yesAdvanced Science, EarlyView.
This study shows that the classical secretory protein S100 calcium‐binding protein A9 (S100A9) can translocate to the nucleus upon de‐phosphorylation at Thr 113 in human amnion fibroblasts at parturition, where S100A9 induces heterochromatin erosion through segregation of the heterochromatin maintenance protein, resulting inLong Interspersed Nuclear ...

Sulfite: Cytochrome \u3cem\u3ec\u3c/em\u3e Oxidoreductase from \u3cem\u3eThiobacillus novellus\u3c/em\u3e [PDF]

open access: yes, 2000
Direct oxidation of sulfite to sulfate occurs in various photo- and chemotrophic sulfur oxidizing microorganisms as the final step in the oxidation of reduced sulfur compounds and is catalyzed by sulfite:cytochrome c oxidoreductase (EC1.8.2.1).

Engineering Electron Transfer Flux between Cytochrome P450 Enzyme and P450 Reductase to Enhance Serotonin Production in Escherichia Coli

open access: yesAdvanced Science, EarlyView.
The electron transfer flux in CPR‐P450 catalytic system is systematically engineered through: i) enhancing electron transfer rate by redesigning the putative electron transfer pathway of CPR; ii) improving electron‐receiving rate by evolving the heme domain of tryptophan‐5‐hydroxylase (T5H); iii) enlarging electron supply by fine‐tuning NADPH synthesis.

Taylor Expansion Proof of the Matrix Tree Theorem - Part I

open access: yes, 2013
The Matrix-Tree Theorem states that the number of spanning trees of a graph is given by the absolute value of any cofactor of the Laplacian matrix of the graph.

Neuronal C/EBPβ Shortens the Lifespan via Inactivating NAMPT

open access: yesAdvanced Science, EarlyView.
Schematic diagram illustrating the mechanism of shortened lifespan in Thy 1‐C/EBPβ transgenic mice and intervention strategies. Briefly, C/EBPβ/AEP escalation in the aging brain triggers NAMPT fragmentation and NAD+ depletion. Knockout of AEP from Thy 1‐C/EBPβ Tg/Tg mice ameliorates cognitive impairments and elongates the lifespan.

Unraveling Neurodevelopment: Synergistic Effects of Intrinsic Genetic Programs and Extrinsic Environmental Cues

open access: yesAdvanced Science, EarlyView.
Overview of the regulation of intrinsic and extrinsic signals during neurodevelopment. Intrinsic genetic signals from NSCs, in conjunction with cues from microglia and blood vessels, collaboratively regulate the proliferation of NSCs, their fate determination, synaptogenesis, synaptic pruning, neuronal survival, and death, as well as communication ...

Targeted Delivery of α‐ketoglutarate to Macrophages in Bone: A Novel Therapeutic Strategy for Improving Fracture Healing in Type 2 Diabetes

open access: yesAdvanced Science, EarlyView.
The study reveals that glutaminolysis in macrophages is inhibited under type 2 diabetes mellitus (T2DM) conditions, which impedes fracture healing by reducing bone morphogenetic protein 2 (BMP2) production through increased cytosine methylation on the promoter.

Apoptotic Bodies Restore NAD and Mitochondrial Homeostasis in Fibroblasts

open access: yesAdvanced Science, EarlyView.
Mesenchymal stem cell‐derived apoptotic bodies (MSC‐ABs) target keloid fibroblasts (KFs), restoring nicotinamide adenine dinucleotide (NAD) metabolism and mitochondrial function, suppressing collagen overproduction, and rebalancing tissue homeostasis, offering a novel therapy for keloid.

SSRP1/SLC3A2 Axis in Arginine Transport: A New Target for Overcoming Immune Evasion and Tumor Progression in Peripheral T‐Cell Lymphoma

open access: yesAdvanced Science, EarlyView.
Enhanced arginine uptake is a critical feature of metabolic reprogramming in PTCL, characterized by elevated expression of the arginine transporter SLC3A2. SLC3A2‐mediated arginine uptake facilitates PTCL proliferation and survival by enhancing OXPHOS metabolism and inducing immune evasion.
