The subcutaneous xenograft tumor formation assay and lung metastasis assay after cotransfecting GC cells with si-ELFN1-AS1 and si-TAOK1 showed that TAOK1 knockdown partially rescued the effect of ELFN1-AS1 slicing on tumor formation and metastasis (Fig. 5K–P). This evidence concerns the gene TAOK1 and neoplasm.
