Venn and GO enrichment analyses of differential phosphoproteins. A Venn diagram of the differential phosphoproteins in the three comparison groups (PEC vs. NEC, GE vs. PEC, and GE vs. NEC) at the protein level. B Venn diagram of the differential phosphoproteins in the three comparison groups (PEC vs. NEC, GE vs. PEC, and GE vs. NEC) at the phosphosite level. C–E GO enrichment analysis of the differential phosphoproteins in PEC vs. NEC, GE vs. PEC, and GE vs. NEC
