CDH11 and gastric cancer: In the present study, we focused on investigating the effects of CDH11 on the prognosis and progression of GC by utilizing multiple public gene expression databases such as Oncomine (https://www.oncomine.org/resource/login.html) [28], Gene Expression Omnibus (GEO, https://www.ncbi.nlm.nih.gov/gds) [29], the Gene Expression Profiling Interactive Analysis (GEPIA, http://gepia.cancer-pku.cn/index.html) [30], Tumor Immune Estimation Resource (TIMER, https://cistrome.shinyapps.io/timer/) [31], and Kaplan-Meier Plotter (KMP, http://kmplot.com/analysis/) [32].
