For example, LINC00461 functions as a ceRNA to regulate ZEB2 expression by sponging miR-30a-5p to promote progression and malignancy in non-small cell lung cancer (29), SNHG15 functions as a ceRNA to promote KLF9-mediated proliferation by acting as a decoy for miR-141-3p in nasopharyngeal carcinoma (30), and DANCR promotes osteosarcoma migration and invasion by acting as a ceRNA that sponges miR-149 to regulate MSI2 expression (31). Here, KLF9 is linked to osteosarcoma.
