Firstly, we selected several genes related to tumor metastasis through the NCBI database and literature, including SRA1, DBF4 zinc finger B (DBF4B), ZNFX1 antisense RNA 1 (ZFAS1), colorectal neoplasia differentially expressed (CRNDE), endoplasmic reticulum lectin (OS9), and others. Here, SRA1 is linked to neoplasm.
