Figure 3. miR-424-5p-induced downregulation of KDR. (A) A volcano map of the differentially expressed miRNAs and mRNAs (n = 19349) identified between the normal samples and the OSCC samples based on data from the GEO dataset. (B) miR-424-5p expression data from the TCGA-OSCC dataset. (C) Survival curves based on miR-424-5p expression data and tumor grade from the TCGA-OSCC dataset. (D) Expression of miR-424-5p in the HOK cell line and OSCC cell lines (n = 4 in each group). (E) TargetScan predicts the binding site between miR-424-5p and promoter of KDR. (F) Dual luciferase reporter gene assay showing the targeted binding of miR-424-5p and KDR. *P < 0.05 **P < 0.01.
