According to transcriptomics data deposited on the Oncomine repository, only 5 glycoproteins were significantly overexpressed in GC (KRT5, HIST1H1D, PSMD2, ANXA2 and SPTAN1), distributed between the different types of gastric tumors, according to the Lauren classification (intestinal, diffuse and mixed type adenocarcinomas), as highlighted in Figure 4A. Gene expression was then matched with the levels of the proteins in gastric tumors, as defined by the Human Protein Atlas (Figure 4B). Here, H1-3 is linked to adenocarcinoma.
