ProteomicsUBA2-High Osteosarcoma Suppresses Immune Infiltration by Autophagy-Mediated MHC-I Degradation
Osteosarcoma (OS) responds poorly to immune-checkpoint blockade (ICB), and the molecular drivers of its immune-cold state remain unclear. Using multi-omics analyses, we identified an immune-cold OS subtype characterized by enrichment of protein SUMOylation and found the SUMO E1 subunit UBA2 as a key...

ProteomicsCDK9 binds and activates SGK3 to promote cardiac repair after injury via the GSK-3β/β-catenin pathway
SGK3 (threonine-protein kinase 3) is a functional kinase we identified previously with the capacity to promote cardiomyocyte proliferation and cardiac repair after myocardial infarction. However, the upstream signals regulating SGK3 are still unknown. Based on the quantitative proteomics data and pu...

ProteomicsLabel-free quantitative proteomic analysis for normal and inflamed colonic mucosa from patients with ulcerative colitis
Label-free quantitative proteomic analysis for clinical tissues of 5 normal and 5 inflamed colonic mucosa. The EASY-nLC 1200 system and Q Exactive Plus were used for peptides detection. A total of 4102 proteins were identified, and 2713 proteins were quantified. According to the criterion fold chang...
