The up‐regulation of mature miR‐7‐1‐3p and miR‐15b‐5p inhibits the expression of target genes POLR3G, CALU, and KIF1B, further decreases the expression of VM‐related genes MMP9 and VE‐cadherin, and ultimately decreasing VM of NPC cells (Fig. 8). This evidence concerns the gene KIF1B and nasopharyngeal carcinoma.
