According to node degrees, top10 miRNAs (such as hsa-miR-16-5p, hsa-let-7b-5p,hsa-miR-15a-5p, hsa-miR-15b-5p, hsa-let-7a-5p andhsa-miR-34a-5p) and genes (such as high mobilitygroup AT-hook 1, HMGA1; BTG family, member 2,BTG2; superoxide dismutase 2, SOD2; and TP53)were selected and listed in Table 2, while they mightbe critical for development of NSCLC (Fig .3). The gene discussed is BTG2; the disease is non-small cell lung carcinoma.
