Compared with the gastric mucosal low-grade/high-grade intraepithelial neoplasia group, the expression level of lncRNA H19 (n = 10, p < 0.05, Figure 2A), LINC00895 (n = 10, p < 0.001, Figure 2B), lnc-SRGAP2C-16 (N = 10, p < 0.001, Figure 2C), lnc-HLA-C-2 (n = 10, p < 0.01, Figure 2D), lnc-APOC1-1 (n = 10, p < 0.0001, Figure 2E) in the GC group was significantly upregulated, while the expression level of lnc-B3GALT2-1 (n = 10, p < 0.01, Figure 2F) was significantly downregulated. This evidence concerns the gene H19 and intraepithelial neoplasia.
