This provides us with new insights for further exploring the biological mechanisms of lncRNA H19, LINC00895, and lnc-SRGAP2C-16 in the process of chronic non-atrophic gastritis and gastric mucosal low-grade or high-grade intraepithelial neoplasia to GC. This evidence concerns the gene SRGAP2C and intraepithelial neoplasia.
