ProteomicsRevealing Stress Granule Compositional Heterogeneity through Antibody-Guided Proximity Labeling
Stress granules (SGs), transient nonmembranous cytoplasmic condensates that formed in response to cellular stresses, require precise characterization to unravel their cell-type and stressspecific protein compositions. This study introduced a G3BP1 antibody-guided proximity labeling (Ab-PL) method to...

MetabolomicsCardiac disruption of SDHAF4-mediated mitochondrial complex II assembly promotes dilated cardiomyopathy
Succinate dehydrogenase, which is known as mitochondrial complex II, has proven to be a fascinating machinery, attracting renewed and increased interest in its involvement in human diseases. Herein, we find that succinate dehydrogenase assembly factor 4 (SDHAF4) is downregulated in cardiac muscle in...

ProteomicsAntibody-Free Profiling of Lysine Dimethylation via Chemoselective OxidationCoupled Reversible Enrichment
Lysine dimethylation (Kme2) is a critical post-translational modification (PTM), while its comprehensive analysis remains challenging due to low stoichiometry and lack of pan-specific antibodies. Here, we developed an antibody-free proteomics strategy combining selective fluorine-mediated oxidation ...

ProteomicsOne-Step Chemoenzymatic Labeling and Oxime-Reversible Enrichment for O-GlcNAc Profiling in Oxidative Stress
Chemoenzymatic labeling has greatly advanced O-GlcNAc proteomics, yet existing strategies using azide-modified donors (e.g., UDP-GalNAz) require multi-step click-based workflows that introduce substantial sample loss and limit sensitivity toward low-abundance targets. While recent one-step labeling ...

ProteomicsIdentification of proteins affected by PTENα under stress conditions by mass spectrometry
Stress granules are known to be related with selective translation. To determine which proteins are regulated by stress granules assembly in Ptenα─/─ MEFs, we performed a mass spectrometry analysis of Ptenα+/+ and Ptenα─/─ MEFs under oxidative stress.

ProteomicsIdentification of PTENα associated proteins under stress condictions in B16 cells by mass spectrometry
PTENα is the first isoform of tumor suppressor PTEN. To investigate the molecular mechanism by which PTENα modulates cell response to inflammation, we performed pull-down assays with FLAG-tagged proteins coupled with mass spectrometry under condition of H2O2 treatment in B16 cells.

ProteomicsPhenotypic heterogeneity analysis of APC-mutant colon cancer by proteomics and phosphoproteomics identifies RAI14 as a key prognostic determinant
Adenomatous polyposis coli (APC) is an important tumor suppressor and most directly related to the regulation of WNT/β-catenin signaling pathway. APC mutation has been identified as an early event in more than 80% of sporadic colorectal cancers (CRCs). However, obvious prognostic differences are obs...
