As shown in Figures 5A–G, KDELR3 was mainly expressed in tumor cells, IDH2 was mainly expressed in endothelial cells, S100A6 was mainly expressed in photoreceptor cells, ITPA was mainly expressed in endothelial cells and tumor cells, PARP8 was mainly expressed in T cells, and APRC1B was mainly expressed in endothelial cells. Here, KDELR3 is linked to neoplasm.
