According to the median ratio of relative GAS5 expression (0.38) in tumor tissues, the 89 gastric cancer patients were classified into two groups: relative high-GAS5 group (n = 45, GAS5 expression ratio ≥ median ratio) and relative low-GAS5 group (n = 44, GAS5 expression ratio ≤ median ratio) (Figure 1B). This evidence concerns the gene GAS5 and neoplasm.
