Engineered Allosteric Biosensor for In Situ DNA Glycosylase Detection in Neuroblastoma Risk Stratification and Drug Resistance Monitoring

Advanced Science, EarlyView.
An engineered allosteric biosensor (UUU‐DZ‐tFNA) was developed, in which UDG specifically recognizes and activates a DNAzyme to achieve signal cycle amplification in a sequentially activatable mode. UUU‐DZ‐tFNA achieves in situ UDG detection across multiple biological levels and facilitates risk stratification and drug resistance monitoring of NB ...

Beyond Nature's Blueprint: Macrocyclic Peptides Containing Unnatural Amino Acids in Therapeutic Development

Angewandte Chemie, EarlyView.
Strategic incorporation of unnatural amino acids transforms macrocyclic peptides into drug‐like molecules capable of engaging challenging targets. These building blocks enhance stability, permeability, and bioavailability, accelerating the development of next‐generation peptide therapeutics.

Transfer RNA‐Derived Small RNA‐5’tiRNAGln Drives HNRNPC Phase Separation to Promote Breast Cancer Bone Metastasis by Regulating IGF1R

Advanced Science, EarlyView.
This study reveals that 5'tiRNA‐Gln interacts with hnRNPC to promote IGF1R liquid‐liquid phase separation, which drives ERK1/2 signaling activation, EMT, and breast cancer bone metastasis. These findings highlight a novel mechanism of breast cancer bone metastasis and potential therapeutic target in metastatic breast cancer.

Distinct Molten‐Globule Conformations in an Interacting Protein Domain Resolved by 19F NMR of Fluoroproline Residues

Angewandte Chemie, EarlyView.
Modifying the conformational ensemble of “molten‐globule” protein by the site‐specific incorporation of stereoisomeric 4‐fluoroproline residues modulated its binding affinity and aggregation behavior. 19F NMR spectroscopy enabled the detection of key interactions responsible for structural and dynamic changes. ABSTRACT Recently, the application of deep

Galactokinase 1 Positively Regulates Mitochondrial Respiration by Phosphorylating TIMM13 as a Protein Kinase

Advanced Science, EarlyView.
GALK1 acts as a protein kinase beyond the phosphorylation of galactose. GALK1 phosphorylates TIMM13 at Y73 in the cytoplasm. This phosphorylation prevents premature oxidative folding of TIMM13 and ensures its entrance into the intermembrane space of mitochondrion, positively regulating mitochondrial respiration.

Conformation‐Selective Binding Domains of Intramolecular Chemically Induced Protein Dimerisation Systems

Angewandte Chemie, EarlyView.
Intramolecular chemically induced dimerisation transforms FK506‐ and cyclosporine A‐responsive protein pairs into high‐affinity pseudo‐allosteric switches. Holo‐selective binders isolated by mRNA display convert these switches into gain‐of‐signal biosensors and ultrasensitive ELISAs, enabling direct quantification of both immunosuppressants in ...

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...
