FN1 was a target of miR-508-5p. (A) Venn diagram indicating potential targets explored by MicroT-CDS and TCGA databases. (B) Predicted binding sites between miR-508-5p and FN1. (C) The secondary structure of miR-508-5p. (D) Examinations of combinations between miR-508-5p and FN1 were verified by dual-luciferase reporter assays in NPC cells. (E) FN1 expression was detected by qRT-PCR in NPC cells transfected with either miR-NC or miR-508-5p mimics. *P < 0.05.
