β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

open access: yesAdvanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

Oligopeptides/DNA Coacervate Droplets as Macromolecular Delivery Microcarriers

open access: yesAdvanced Science, EarlyView.
Oligopeptide–DNA coacervates formed via liquid–liquid phase separation serve as programmable carriers for macromolecular cargos, entering cells through lipid raft–associated pathways and subsequently undergoing enzyme triggered intracellular disassembly driven by DNA degradation processes, thereby enabling efficient, controlled, and spatially defined ...

Imaging‐Guided Live Single‐Cell Lipid Profiling of Leader and Follower Cells During Collective Migration of Triple‐Negative Breast Cancer Cells

open access: yesAdvanced Science, EarlyView.
Integrated single‐cell mass spectrometry reveals distinct lipidomic signatures that differentiate leader and follower phenotypes in migratory breast cancer cells. Phenotype‐specific alterations across various lipid classes, including fatty acids and phosphatidylcholines, underpin functional heterogeneity.

Membrane Fusion‐Mediated Cytosolic Delivery of Threose Nucleic Acids via Homotypic Nanoparticles Overcomes Drug Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study introduces a biomimetic “nanofusion” platform that integrates the biostability of threose nucleic acids (TNA) with homotypic cell‐membrane cloaking to combat drug‐resistant TNBC. By leveraging a non‐canonical membrane‐fusion pathway for direct cytosolic delivery, the platform bypasses endosomal sequestration. To achieve potent AKT2 silencing

Predicting Catalyst Performance From Pt/CeO2 Redispersion Kinetics

open access: yesAngewandte Chemie, EarlyView.
Unravelling kinetics of dynamic structural changes in catalysts is the key to predicting their catalytic properties. ETEM experiments reveal a continuous decrease in Pt particle size on cube‐shaped CeO2 under oxidizing conditions, changing from large nanoparticles to highly dispersed species.

Cholesterol Laundry of Cell Membrane and Fatty Liver by Detergent Liposomes to Improve Anti‐Cancer Drug Responsiveness of Patient Liver Tissues

open access: yesAdvanced Science, EarlyView.
Cholesterol‐enriched plasma membranes in hepatocellular carcinoma impede drug penetration. Cholesterol (+)‐liposomes act as membrane‐specific detergents, extracting cholesterol and reducing barrier function without cytotoxicity. Following endocytosis, cholesterol transfers from endosomes to liposomes and is metabolized in the ER.

Loss of hepatic SMLR1 causes hepatosteatosis and protects against atherosclerosis due to decreased hepatic VLDL secretion

open access: yesHepatology, EarlyView., 2022
The role of SMLR1 in lipid metabolism (high fat + cholesterol diet in mice) Abstract Background and Aims The assembly and secretion of VLDL from the liver, a pathway that affects hepatic and plasma lipids, remains incompletely understood. We set out to identify players in the VLDL biogenesis pathway by identifying genes that are co‐expressed with the ...

Oxygen‐Tolerant Photo‐Induced Miniaturized Accelerated Atom Transfer Radical Polymerization (OPTIMA‐ATRP) for High‐Throughput Synthesis of Polymer Bioconjugates

open access: yesAngewandte Chemie, EarlyView.
Oxygen‐tolerant photo‐induced miniaturized accelerated atom transfer radical polymerization (OPTIMA‐ATRP) in water was developed for the polymerization of hydrophilic (meth)acrylate monomers under ambient or sub‐ambient (4°C) temperature and atmospheric conditions, without prior degassing, in less than 10 min, at an ultra‐small scale (< 50 µL) in ...

Partition profile of the nicotinic acetylcholine receptor in lipid domains upon reconstitution[S]

open access: yesJournal of Lipid Research, 2010
The nicotinic acetylcholine receptor (AChR) is in intimate contact with the lipids in its native membrane. Here we analyze the possibility that it is the intrinsic properties of the AChR that determine its partition into a given lipid domain.
