Moreover, to assess whether SNHG20 was differentially expressed in NSCLC tissues, 42 NSCLC patients were classified into two groups relative to the median ratio of SNHG20 expression in tumor tissues: relative high SNHG20 group (n=21, SNHG20 expression ratio≥median ratio) and relative low SNHG20 group (n=21, SNHG20 expression ratio≤median ratio) (Figure 1c). This evidence concerns the gene SNHG20 and neoplasm.
