First, differential analysis was performed on genes in TCGA-LUAD dataset, and 533 downregulated DEmRNAs were intersected with predicted mRNAs to obtain 4 target genes (Figure 3(a)), among which STARD13 had the strongest inverse correlation with miR-182-5p (Figure 3(b)) and was prominently lowly expressed in cancer tissue (Figure 3(c)). This evidence concerns the gene STARD13 and cancer.
