FGF7 and pancreatic adenocarcinoma: These genes were overlapped with 9,170 DEGs in PAAD, which were obtained by comparing the mRNA expression profile between pancreatic cancer in TCGA and the normal pancreas in GTEx; six specific genes were found, including VWF, GNG11, FGF7, TNXB, IL3RA, and LPAR1 (Figure 5a and b).
