Golgi self-correction generates bioequivalent glycans to preserve cellular homeostasis

eLife, 2016
Essential biological systems employ self-correcting mechanisms to maintain cellular homeostasis. Mammalian cell function is dynamically regulated by the interaction of cell surface galectins with branched N-glycans. Here we report that N-glycan branching

Bio‐Inspired Oligocellulose‐Regulated Ice‐Water Interfaces Enable Sustained Ion Transport in Frozen Aqueous Zinc Batteries

Advanced Science, EarlyView.
Inspired by antifreeze glycoproteins (AFGPs), we synthesized a type of oligomeric cellulose (OC‐8) to inhibit ice formation and enlarge the inter‐ice water channel for transportation. Typical confocal fluorescence experiments display the expansion of the ice‐water interface for zinc‐ion transport.

8-plex LC-MS/MS Analysis of Permethylated N-glycans Achieved by Using Stable Isotopic Iodomethane

, 2019
Glycosylation is an important post-translational modification of proteins. Many diseases, such as cancer have proved to be related to aberrant glycosylation.

CHST1 Drives Immunotherapy Resistance in Triple‐Negative Breast Cancer by Orchestrating an Immunosuppressive Microenvironment via the NKRF–CCL20–Macrophage Axis

Advanced Science, EarlyView.
Proposed model of CHST1‐associated immune remodeling in triple‐negative breast cancer. In CHST1‐low tumors, greater nuclear accumulation of NKRF is associated with repression of an NF‐κB‐related CCL20 transcriptional program and an immune‐inflamed microenvironment.

ACSL4‐Dependent Lysosomal Lipid Peroxidation Links WTAP‐Mediated m6A Modification to Intervertebral Disc Degeneration

Advanced Science, EarlyView.
IL‐1β upregulates the protein level of WTAP, which promotes the m6A modification of ACSL4 mRNA in an IGF2BP2‐dependent manner, thereby enhancing its stability. The increased ACSL4 drives lipid peroxidation, leading to lysosomal membrane permeabilization (LMP) and impaired mitophagy, which collectively accelerate intervertebral disc degeneration (IVDD).

Carbohydrate‐Directed Labeling Probes for UV‐Independent Chemoproteomic Profiling of Carbohydrate–Protein Interactions

Angewandte Chemie, EarlyView.
Modular carbohydrate‐directed labeling probes (CDLPs) convert weak carbohydrate–protein interactions into durable covalent tags in live cells without the need for multivalency or UV irradiation. Ligand binding triggers proximity‐enabled, glycan‐releasing acyl transfer to install a click handle for protein tagging and chemoproteomic profiling.

Oligosaccharides With Defined Glycosidic Bonds Shape Gut Microbial Succession and Metabolism Via Bond‐Specific Microbial Responders

Advanced Science, EarlyView.
Oligosaccharides with defined glycosidic bonds drive divergent gut microbial succession and shape unique metabolic profiles. Absolute time‐series profiling with Bayesian generalized Lotka–Volterra modeling identifies bond‐specific microbial responders, while monoculture validation and metaproteomics reveal linkage‐matched transport and cleavage modules.

The Nature of Cell‐Penetrating Poly(disulfide)s

Angewandte Chemie, EarlyView.
The mode of action of cell‐penetrating poly(disulfide)s (CPDs) is elucidated to understand thiol‐mediated uptake (TMU) in general and guide future efforts to control cellular entry for chemicals delivery and pathogen defense. ABSTRACT Cell‐penetrating poly(disulfide)s (CPDs) are the most popular thiol‐mediated uptake (TMU) tools for delivering attached

Combination of Microwave-Assisted Girard Derivatization with Ionic Liquid Matrix for Sensitive MALDI-TOF MS Analysis of Human Serum N-Glycans

Journal of Analytical Methods in Chemistry, 2018
We developed a new method for MALDI-TOF MS detection of N-glycans derived from human serum. The synergistic combination of microwave-assisted Girard T derivatization, solid-phase extraction desalting, and an ionic liquid matrix (2, 5-dihydroxybenzoic ...

CRISPR and Gene Augmentation Rescue Trabecular Meshwork Dysfunction in iPSC Models of Lowe Syndrome

Advanced Science, EarlyView.
By modeling Lowe syndrome using patient‐derived iPSCs, this study establishes a human disease model that faithfully recapitulates OCRL deficiency‐associated ciliary and cytoskeletal defects. The model enables evaluation of both mutation‐agnostic DNA augmentation and CRISPR‐mediated mutation correction strategies, both of which restore OCRL function and
