SLC2A1 and pancreatic neoplasm: We also acquired the GLUT1 mRNA expression from the Human Protein Atlas (Human Protein Atlas proteinatlas.org)29, and the GLUT1 mRNA was highly expressed in pancreatic cancer tissues with an average abundance of expression of 43.5 FPKM (fragments per kilobase of transcript per million fragments mapped) and ranging from 20.3 FPKM to 85.8 FPKM (Figure 9C).
