Schematic workflow of materials and methods. Samples from endometrial tissues of NE () and EC cases () were collected in two biological replicates. Similar amounts of proteins were digested into peptides using Trypsin and Lys-C Mix enzymes. The digested peptides were subsequently extracted and desalted. All samples were pooled together after 4-plex iTRAQ labeling and analyzed using 2D LC-MS/MS. Tag 116 and 117 for endometrial tissues of normal cases and 114 and 115 for endometrial tissues of EC cases, respectively.
