Maternal Hyperglycemia Disrupts Cerebral Cortex Development Through the Foxp1‐Dll1‐Notch Axis

open access: yesAdvanced Science, EarlyView.
Maternal hyperglycemia disrupts offspring cortical development through a Foxp1–Dll1–Notch signaling axis. In a PGDM mouse model, intrauterine hyperglycemia decreases cortical thickness and perturbs neuronal layering by downregulating Foxp1, which transcriptionally regulates the Notch ligand Dll1.

PDHA1 Hyperactivation‐Mediated Glucose Metabolism Reprogramming Fuels Neutrophil NETosis and Promotes Acute Lung Injury

open access: yesAdvanced Science, EarlyView.
During NETosis, neutrophils shift metabolically toward enhanced OXPHOS and partially reduced glycolysis. This shift is driven by PDHA1 hyperactivity‐dependent selective metabolic reprogramming. The neutrophil‐targeted nanoparticle 3‑FP‑BSA NPs effectively inhibit NETosis and attenuate ALI.

Turn Residues in β-Hairpin Peptides as Points for Covalent Modification

open access: yes, 2016
β-Turns are important sites for protein−protein and protein−peptide interactions, but little research has explored synthetic modifications of turn residue side-chains in a β-hairpin peptide. To this end, β-hairpin peptides were synthesized containing the

A Fish MDA5 Integrates Canonical RIG‐I and MDA5 Ligand Recognition

open access: yesAdvanced Science, EarlyView.
These results show that the large yellow croaker lacks RIG‐I, yet its MDA5 senses both 5′ppp‐dsRNA and long dsRNA. A flexible RNA‐capping loop in the MDA5 C‐terminal domain enables two ligand‐binding modes. This dual recognition signals through MAVS–STING–TBK1/IRF3 and induces type I interferons, revealing unexpected plasticity in vertebrate antiviral ...

The VCPIP1‐UBE3A Deubiquitination‐Ubiquitination Cascade Contributes to Castration‐Resistant Prostate Cancer Progression

open access: yesAdvanced Science, EarlyView.
VCIPIP1 emerges as a molecular link between protein stability and prostate cancer progression. By deubiquitinating and stabilizing UBE3A, VCIPIP1 promotes p53 degradation and progression to castration‐resistant prostate cancer. Elevated VCIPIP1 expression is associated with shorter castration‐resistant prostate cancer–free survival, highlighting the ...

Histone Lactylation Drives WNK1 Expression to Promote Esophageal Squamous Cell Carcinoma Progression Through Histone H3 Ser10 Phosphorylation

open access: yesAdvanced Science, EarlyView.
In brief. Yan et al. demonstrated that the excess lactate produced by the enhanced glycolysis pathway in esophageal cancer can lactylate H3K23, H3K23la can be enriched in the WNK1 promoter region to promote WNK1 expression, thereby increasing the phosphorylation of the p‐H3 Ser10 site, and p‐H3S10 can be enriched in the AKT1 promoter region to promote ...

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

open access: yesAngewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Integrated Multiomic Analysis Reveals an EBV‐Associated MIF–SPP1+ Macrophage Axis Linking Tumor Stemness and Immune Dysfunction in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, EarlyView.
This study maps how Epstein–Barr virus reshapes the cellular ecosystem of nasopharyngeal carcinoma. It identifies SPP1+ macrophages as partners of stemness‐associated tumor cells and dysfunctional T cells, links tumor‐derived MIF to macrophage recruitment and programming, and shows that macrophage‐derived SPP1 promotes tumorsphere formation and impairs

Accessibility and Alignment of Trans‐Cleavage Substrates Modulate the Kinetics of Cas12a Ribonucleoprotein

open access: yesAngewandte Chemie, EarlyView.
Two key binding events that collectively determine the catalytic efficiency of trans‐cleavage: (1) the substrate passing through the gap between the REC and NUC domains, determined by Kpass, and (2) the alignment of the substrate with the catalytic triad of the ribonucleoprotein, determined by Kalign.

Folding of a β-hairpin peptide derived from the N-terminus of ubiquitin: Conformational preferences of β-turn residues dictate non-native β-strand interactions

open access: yes, 2000
The role of the non-native β-turn sequence (NPDG) in nucleating the folding of a β-hairpin peptide derived from the N-terminus of ubiquitin, has been examined by NMR and CD spectroscopy.
