Extending single-cell proteomics from HeLa to small primary human immune cells

Abstract Single-cell proteomics (SCP) holds the promise of decoding cellular heterogeneity at the functional level, yet achieving deep and reproducible proteome coverage from individual cells has remained a formidable challenge. Here, we establish a high-sensitivity, label-free S...

Cullin 3 ubiquitin ligase regulates redox defense and metabolic programs in proximal tubule cells

Abstract Background Chronic kidney disease (CKD) is characterized by proximal tubule (PT) stress, oxidative injury, and metabolic dysfunction. Human kidney single-nucleus RNA-sequencing (snRNA-seq) identified enrichment of ubiquitin-dependent protein catabolic processes in injure...
