FOXL2 and non-small cell lung carcinoma: By overlapping the miRNAs predicted in the online biological databases miRDB (https://www.mirdb.org/) and TargetScan Human (http://www.targetscan.org/), as well as the downregulated miRNAs in the miRNA microarray of four paired NSCLC and normal tissues, we identified miR‐133b as a potential upstream regulator of FOXL2 (Figure 5A).
