DUSP5 and gastric cancer: For example, the oncogenic lncRNA linc01503 in gastric cancer interacts with zeste homolog 2 (EZH2) and lysine (K)-specific demethylase 1A (LSD1) enhancers, targeting the promoter regions of dual-specificity phosphatase 5 (DUSP5) and cyclin-dependent kinase inhibitor 1A (CDKN1A).
