Overlap analysis of differentially expressed proteins among four NFPA subtypes (NF-, LH-, FSH-, and LH/FSH-). Each number in this figure is corresponded to the SSP number in the Table 1. Those duplicated SSP Numbers in the Table 1 are re-labeled in this figure as following: 1017(1) = Chain 1, somatotropin; 1017(2) = Splice isoform 2 of somatotropin precursor; 1103(1) = Somatotropin precursor; 1103(2) = Growth hormone variant precursor; 2310(1) = F-actin capping protein beta subunit; 2310(2) = Splice isoform 2 of F-actin capping protein beta subunit; 2419(1) = Guanine nucleoide-binding protein G(O), alpha subunit 1; and 2419(2) = Guanine nucleotide-binding protein G(O), alpha subunit 2. The red color number refers to an upregulated protein. The black color number refers to a downregulated protein. The label (*) means those DEP-spots are common to only two groups of LH- and FSH-NFPA, not to NF-NFPA.
