Mucin Glycoprotein Nanoparticles Enable a Selective Antisense Therapy for Oncogenic MicroRNAs

Advanced NanoBiomed Research, EarlyView.
Mucin glycoproteins are turned into nanoparticles by employing synthetic DNA strands, which have a dual function: they stabilize the nanoparticles and act as binding sites for intracellular miRNA‐21. Thus, upon internalization into tumor cells, these mucin nanoparticles can deplete miRNA‐21 from the cytosol, which induces apoptosis in vitro and in vivo.

Hydrophilic Janus Micelles From an ABC Triblock Copolymer

Angewandte Chemie, EarlyView.
An amphiphilic triblock copolymer with poly(ethylene glycol) (PEG) and poly(N‐vinylpyrrolidone) (PVP) coronas self‐assembles into spherical micelles with Janus‐type surface segregation in water. Cryo‐TEM, enabled by selective PVP labeling, and 1H‐NOESY NMR reveal phase separation.

Nanostructured Lipid Carriers Overcome the Low Immunogenicity of M2e Peptide via Surface Click Chemistry Conjugation, Improving the Anti‐M2e Antibody Response

Advanced NanoBiomed Research, EarlyView.
1) Nanostructured lipid carriers efficiently vectorize low‐immunogenic M2e peptide. 2) M2e peptide conjugation via click chemistry preserves the peptide key epitopes. 3) Forty M2e peptides per nanoparticle are sufficient to induce robust immune responses.

Chemical Proteomics Identifies Ketogenesis‐Mediated Cysteine Modifications Regulating Redox Function

Angewandte Chemie, EarlyView.
Herein, we report ketone body induce cysteine modifications beyond lysine acylation, as revealed by integrating chemical proteomics with open‐search methods. Among the modifications, cysteine crotonation (Ccr) was chemically validated by endogenous peptide‐based co‐elution assays.

From Covalent Traps to Fluorescent Beacons: The Expanding Arsenal of Chemical Probes for Studying Ubiquitin and Ubiquitin‐Like Proteins

Angewandte Chemie, EarlyView.
A large variety of chemistry‐based ubiquitin probes have been developed. ABSTRACT Ubiquitin (Ub) and ubiquitin‐like proteins (Ubls) orchestrate diverse cellular processes through reversible post‐translational modification of target proteins. Their conjugation is governed by a cascade of E1 activating, E2 conjugating, and E3 ligating enzymes, while ...

Harnessing Methyltransferase‐Guided Targeting for Sequence‐Specific Proximity Labeling of DNA

Angewandte Chemie, EarlyView.
A novel methyltransferase‐mediated approach leveraging rationally designed S‐adenosyl‐L‐methionine (SAM) analogues was developed to achieve sequence‐specific DNA labeling but in proximity to the natural transfer site, addressing key limitations of previously established methods, including ligand instability and methylation‐sensitive labeling.

Fluorine‐18‐Labeled Nucleotide Analogs Targeting Ecto‐5'‐Nucleotidase (CD73) for Positron Emission Tomography Imaging of Solid Tumors

Angewandte Chemie, EarlyView.
Fluorine‐18‐labeled CD73 inhibitor [18F]PSB‐19427 enables noninvasive PET mapping of CD73 overexpression in triple‐negative breast (TNBC) and pancreatic cancer. For [18F]PSB‐19427, specific binding in human tumor tissues, favorable biodistribution with prolonged blood retention, robust tumor uptake, and superiority to [18F]FDG in a TNBC model ...
