We retrieved from the allOnco database (http://www.bushmanlab.org/links/genelists) found that most of them targeted genes involved in newly identified ceRNA network are definite tumor-related genes, such as WT1, MAPK4, MYCN, CNTN4, ADAMTSL3, KLF4, PAX3, ALK, EPHA7, ANLN, WIF1, PAX7, CTNND2, ADAM12 and FOSL1. This evidence concerns the gene KLF4 and neoplasm.
