Therefore, the eight genes (MEOX2, FGF7, DPT, LAMP3, CILP, TMEM119, PMP2, GLDN) that were predicted as differentially expressed between intra- and extracranial metastases in our and at least two of the three related studies (Fig. 6) were summarized in Table 2 to provide an overview of their expression behavior, biological functions, and associations with cancer. Here, FGF7 is linked to cancer.
