Furthermore, we analyzed data from TCGA database to show that the expression levels of mature miR-9-5p in lung cancer tissues (n = 999) were much higher than those in normal tissues (n = 91) (Fig. 7d), indicating that the high levels of NAT10 in cancers (Fig. 6a, b) up-regulated mature miR-9-5p production. This evidence concerns the gene NAT10 and lung cancer.
