Proteomic characteristics of vessels in patients with chronic kidney disease

In this study, isobaric tags for relative and absolute quantification (ITRAQ) and Q Exactive mass spectrometer were used for non-targeted proteomic profiling of forearm arteries and veins in patients with chronic kidney disease stage 5 (with or without diabetes mellitus, obtained from arteriovenous fistula surgery) and healthy controls (obtained from patients with forearm trauma). Protein identifications were acquired against the Uniport Human database. As a result, 497609 spectra were obtained and 3244 proteins were identified with 96525 matched peptides.
