NSD2 is a direct target of miR-1224-5p in 5-FU-resistant OSCC cells
(A) The Venn diagram showed the downstream target genes which could bind with miR-1224-5p in PITA, RNA22, miRmap, and microT databases. (B) Starbase website predicted putative-binding sites between miR-1224-5p and NSD2. (C) NSD2 expression was detected by RT-qPCR in cells transfected with miR-1224-5p mimics. (D) RIP assays were conducted to confirm miR-1224-5p and NSD2 coexisted in RNA-induced silencing complexes (RISCs). (E) Luciferase reporter assay was conducted to verify the combination between miR-1224-5p and NSD2. (F) NSD2 expression was detected in HSC-3/5-FU and HN-4/5-FU cells transfected with NC mimics, miR-1224-5p mimics, or miR-1224-5p mimics+oe-APCDD1L-AS1. **P< 0.01, ***P < 0.001.
