As shown in Fig. 1, Box-and-Whisker plot shows that G9a mRNA level was moderately variable in NSCLC tissues, and it was substantially higher in at least half of both LUAD N( N = 517; Fig. 1a) and LUSC N( N = 494; Fig. 1b) samples in comparison to normal lung tissues (N = 105). The gene discussed is EHMT2; the disease is non-small cell lung carcinoma.
