Data collected from the database (TCGA-COAD project deposited in GDC Data Portal, https://portal.gdc.cancer.gov/, accessed on 15 November 2021) revealed that the GalR1 and GalR2 mRNAs levels were higher in normal adjacent tissue; however, the GalR3 gene expression was stable in both cancer and adjacent normal tissue (Figure 7). Here, GALR2 is linked to cancer.
