ProteomicsOrthogonal Ionic Liquid-based Extraction Strategy Enables Amyloid-Specific Profiling of the Aggregate Proteome
Amyloid deposits are key pathological features of neurodegenerative diseases, yet their structural heterogeneity coupled with a stable β-sheet fibrillar architecture makes them extremely insoluble and difficult to isolate. Through systematic screening and molecular dynamics simulations, we identifie...

ProteomicsTop-down proteomics of membrane proteoforms from HeLa cells and mouse hippocampus
Comprehensive characterization of membrane proteins at the level of proteoforms in complex biological samples by top-down mass spectrometry is of vital importance in revealing their precise functions. Based on a novel membrane protein separation technology, we obtained a dataset of membrane proteofo...

ProteomicsProteoform Imaging by Combining MALDI MSI and High-sensitivity Top-down Proteomics
Spatially resolved characterization of proteoforms has great potential to significantly advance our understanding of physiological and disease mechanisms. However, it faces challenges regarding throughput and coverage. Herein, we developed a robust method for high-throughput proteoform imaging (HTPi...

ProteomicsA multiplex fragment ion-based method for accurate proteome quantification
We developed a multiplex pseudo-isobaric dimethyl labeling (m-pIDL) method for proteome quantification to extend the capacity of the fragment ion-based method to 6-plex by one-step dimethyl labeling with several millidalton and dalton mass differences between precursor ions and enlarging the isolati...

ProteomicsBis(zinc(II)-dipicolylamine) functionalized sub-2 μm core-shell microspheres enabled comprehensive analysis of N-phosphoproteome
Herein, bis(zinc(II)-dipicolylamine) functionalized sub-2 μm core-shell silica microspheres (SiO2@DpaZn) were tailored for N-phosphopeptide enrichment at pH 7.7. Contributed by the coordination bonding between Zn(II) and phosphate groups with the KD value of 13.14 μM, N-phosphopeptides could be capt...

ProteomicsAffinity peptide ligands: New tools for chasing non-canonical N-phosphoproteome
Protein N-phosphorylation enrichment is faced with great difficulties due to the intrinsic instability of the N-P bond, which has seriously hindered its biological function unraveling. Current methods for N-phosphopeptides enrichment are challenging to fulfil high selectivity for all types of N-phos...

Proteomics5-fluorouracil (5-Fu) resistant Bel/5Fu cell line and its parent Bel7402 cell line
The extensive drug resistance of hepatocellular carcinoma (HCC) has become the main cause of chemotherapy failure. The mechanisms leading to drug resistance in tumor cells are not well understood. Previous studies demonstrated that plasma membrane proteins play important roles in mediating drug disp...
