Site- and structure-specific characterization of N-glycoprotein markers of MCF-7 cancer stem cells using isotopic-labelling quantitative N-glycoproteomics

Abstract

High-throughput proteome-level characterization of stemness markers of MCF-7 cancer stem cells was carried out using our recently developed site- and structure-specific isotopic-labeling quantitative N-glycoproteomics pipeline. 144 differentially expressed intact N-glycopeptides were quantified all at once yet with good accurate consistency with the individual biochemical measurements of proteins, RNA or DNA.
