In NPC, miR-24 suppressed cell prolifearation, migration, and invasion and increased the readiosensitivity of cells to iridiation by targeting SP1 (specificity protein 1), FSCN1 (fascin actin-bundling protein 1), and Jab1 (Jun activation domain-binding protein 1), respectively, funcioning as a tumor suppressor (9, 24, 26). This evidence concerns the gene SP1 and nasopharyngeal carcinoma.
