The microarray analysis showed that there were 51 differentially expressed miRNAs in NSCLC, and the top 10 upregulated and downregulated miRNAs are shown in Figure 3A. We found 20 miRNAs that targeted RASSF1A, though only miR‐330‐3p was involved in both groups (Figure 3B,C). This evidence concerns the gene RASSF1 and non-small cell lung carcinoma.
