Of the 121 candidate genes listed in the website database (Supplementary Table 11), two genes (fibroblast growth factor 20; FGF20 and tumor necrosis factor superfamily member 9; TNFSF9) overlapped with DEGs in FAP(+) CAFs at the tumor invasive margin between EOCC and LOCC tumors, and with the DEGs in PanCK(-) AOIs between the tumor invasive margin and tumor center in EOCC tumors (Fig. 5a). The gene discussed is FGF20; the disease is neoplasm.
