Cluster analysis of differentially expressed proteins in the group of gastric type, pancreatic type, and intestinal type. The hierarchical clustering results are represented as a tree heat map, with the ordinate representing significantly differentially expressed proteins and the abscissa representing sample information. Significant differences in protein expression in the different numerical expression quantities (log₂ expression) of the samples with different colors are shown on the heat map, where red or blue represents significantly upregulated or downregulated proteins, and gray represents no quantitative information for proteins. ATG12 represents the protein name of Q94817, IGF2 represents the protein name of p03814, and IRS2 represents the protein name of Q9Y4H2.
