Fe‐Photocatalyzed Decarboxylative Giese‐Type Reaction of α‐N, O or S Carboxylic Acids: Insight into the Mechanism of the Radical Formation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Electron‐deficient alkenes can be functionalized with α‐amino, α‐alkoxy and α‐alkylthio radicals formed by Fe‐photocatalyzed decarboxylation of the corresponding carboxylic acids. The reactions proceed under smooth ligandless conditions with inexpensive base and in the absence of oxidant. A mechanistic computational TD‐DFT study supports the occurrence

Copper and Iron‐Based Metal‐Organic Frameworks for Synergistic Cancer Phototherapies: Recent Advances, Challenges, and Future Prospects

open access: yesAdvanced Therapeutics, EarlyView.
The graphical abstract illustrates the combined effect of PTT and PDT using metal‐organic frameworks (MOFs) in a cancer treatment model. Tumor‐bearing mice are irradiated with different laser lights, which activate the MOF nanoparticles within cancer cells. The MOFs produce reactive oxygen species through PDT, while PTT elevates the temperature to kill

Epigenetic Activation of CCDC183‐AS1 Promotes Osteoclastogenesis and Prostate Cancer Bone Metastasis Through the FUBP1/LIGHT Axis

open access: yesAdvanced Science, EarlyView.
CCDC183‐AS1 overexpression enhanced the ability of PCa cells to spread to the bone by inducing osteoclastogenesis. Mechanistically, CCDC183‐AS1 interacted with FUBP1 and enhanced its stability, which promoted the transcription of TNFSF14 (LIGHT). Copy number gain‐induced KDM5C epigenetically upregulated CCDC183‐AS1 expression by recruiting TET1 to the ...

An Allele of Glutamate Formiminotransferase Triggers 5‐Methyl‐Tetrahydrofolate‐to‐MeFox Conversion and Facilitates Folate Biofortification in Maize

open access: yesAdvanced Science, EarlyView.
This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.

Supply of sulphur to S-deficient young barley seedlings restores their capability to cope with iron shortage [PDF]

open access: yes, 2010
The effect of the S nutritional status on a plant's capability to cope with Fe shortage was studied in solution cultivation experiments in barley (Hordeum vulgare L. cv. Europa). Barley is a Strategy II plant and responds to Fe deficiency by secretion of

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

open access: yesAdvanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

Skullcapflavone II Inhibits SLC1A4‐Mediated L‐Serine Uptake and Promotes Mitochondrial Damage in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
Skullcapflavone II (SkII) significantly alters serine metabolism in gastric cancer cells by directly targeting the L‐serine transporter SLC1A4, thereby inhibiting L‐serine uptake rather than de novo synthesis. This disruption of serine metabolism by SkII leads to increased oxidative stress and consequent mitochondrial damage.

5’‐Methylthioadenosine Metabolic Reprogramming Drives H3K79 Monomethylation‐Mediated PAK2 Upregulation to Promote Cadmium‐Induced Breast Cancer Progression by Impairing Autophagic Flux

open access: yesAdvanced Science, EarlyView.
Cadmium, a carcinogenic heavy metal, drives breast cancer progression via metabolic reprogramming and autophagic flux disruption. Multi‐omics revealed cadmium‐induced 5'‐methylthioadenosine depletion activates DOT1L‐mediated H3K79me1 at PAK2 promoter, upregulating PAK2 to block autophagy and driving malignancy. Clinically, 5'‐methylthioadenosine levels

Critical Role of IL1R2‐ENO1 Interaction in Inhibiting Glycolysis‐Mediated Pyroptosis for Protection Against Lethal Sepsis

open access: yesAdvanced Science, EarlyView.
The authors have discovered that intracellular interleukin 1 receptor 2 (IL1R2) negatively regulates pyroptosis and inflammation by inhibiting glycolysis in sepsis. Soluble IL1R2 is released from macrophages undergoing pyroptosis. IL1R2 acts as a novel negative regulator of glycolysis by interacting with enolase 1 (ENO1), thereby inhibiting gasdermin D
